The transverse movement assembly includes a mast that can be moved laterally and is arranged at the front end of the forklift body. The rotating assembly includes a rotating frame that can be rotatably connected to the lifting frame. The fork assembly is fixed to one side of the rotating frame and can move with the rotating frame. A first guide groove arranged in the vertical direction is provided on the front side of the mast, and a recess is provided in the first guide groove. The lifting assembly includes a lifting frame that can be lifted and lowered on the mast, a lifting cylinder for driving the lifting frame, and an oil pipe for supplying oil to the lifting cylinder. The forklift can only perform forking work and cannot meet the diverse material handling needs. Summary of the Invention

[0004] The present invention provides a multifunctional lifting attachment for forklifts. By setting a rotating mechanism and its mounting position, tools suitable for handling various cargoes can be installed on the mounting position to fix the cargo, thereby realizing multifunctional operations such as forking or clamping, and meeting diverse material handling needs.

[0005] A further object of the present invention is to provide a lateral movement mechanism, a transverse movement mechanism and a vertical movement mechanism so that the multifunctional lifting attachment can move in multiple directions, such as left and right, front and back, up and down, and rotate 360°, so that the goods can be transported and placed more conveniently.

[0006] A further object of the present invention is that the lateral movement mechanism, the transverse movement mechanism and the vertical movement mechanism cooperate with each other so that the force is stable and uniform, and each important component can be disassembled for easy maintenance.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a multifunctional lifting attachment for a forklift, which is installed on a fork frame of a forklift, comprising a mounting frame, which is installed on a forklift, a side shift mechanism being provided in the mounting frame, a transverse shift platform being installed on the side of the mounting frame, a transverse shift mechanism being installed on the transverse shift platform, a guide groove in which a vertical shift mechanism is installed is provided on the transverse shift mechanism, and a rotating mechanism is installed at the bottom end of the vertical shift mechanism; both ends of the transverse shift mechanism are slidably installed in grooves relatively arranged on the transverse shift platform, a mounting position is provided at the bottom end of the rotating mechanism, and a handling tool is detachably installed on the mounting position.

[0008] Preferably, support platforms and transverse drive components are provided at both ends of the transverse platform, and both ends of the support platform are fixed on the channel steel. U-shaped plates are provided at both ends of the support platform, and the top and bottom ends of the U-shaped plates are fixed to the upper and lower surfaces of the channel steel by bolts respectively. The channel steel openings of the transverse platform are inwardly arranged relative to each other. The transverse platform includes two channel steels, one end of which is fixed to the mounting frame, and they are symmetrically arranged on the same horizontal plane. A stabilizing plate is provided on the lower surface of the two fixed ends of the mounting frame. The stabilizing plate is L-shaped, with one end fixed to the surface of the mounting frame and the other end fixed to the lower surface of the channel steel. The channel steel and the mounting frame are arranged vertically. This structural design makes the transverse platform more stable during movement and can withstand greater loads, effectively avoiding the risk of goods falling due to the shaking of the transverse platform, and improving the safety and reliability of transportation. At the same time, the connection method of fixing with bolts facilitates disassembly and maintenance, reducing maintenance costs and time.

[0009] Preferably, the transverse movement mechanism includes a transverse movement plate, and a number of pulleys are provided at both ends of the transverse movement plate through a mounting plate, and the pulleys and the mounting plate are slidingly arranged in the channel steel. This provides a guiding and friction reducing function. The top and bottom surfaces of the pulleys are adapted to the groove of the channel steel and are in contact and sliding connection, and in contact with the groove wall. The front and rear positions of the transverse movement plate are adjusted by controlling the movement of the lead screw by a motor. The setting of the pulleys greatly reduces the friction of the transverse movement plate during movement, making the transverse movement smoother and improving the handling efficiency. The movement of the lead screw controlled by the motor can accurately adjust the position of the transverse movement plate and achieve precise handling, which is suitable for occasions where the placement of goods is required to be high.

[0010] Preferably, a guide groove is provided on the transverse plate, and the top of the vertical movement mechanism is fixedly connected to a vertical movement drive assembly mounted on the transverse plate via a fixed plate, and the vertical movement drive assembly is fixed to one side of the guide groove on the transverse plate. The guide groove is provided on the upper surface of the transverse plate and is a rectangular shell with upper and lower openings. The guide groove design provides stable guidance for the vertical movement mechanism, ensuring that the vertical movement mechanism does not deviate during the up and down movement process, thereby improving the stability and safety of transportation. At the same time, this structural layout makes the entire device more compact, saves space, and is convenient for use in confined areas.

[0011] Preferably, the vertical movement mechanism includes a square tube, and channel steels are respectively provided on two opposite sides of the square tube, and the openings of the two channel steels are arranged in opposite directions facing outward. The size of the square tube and the channel steel is smaller than the inner diameter of the guide groove. The vertical movement drive component is a lifting cylinder, and the upper and lower positions of the vertical movement mechanism are controlled by the lifting cylinder. The use of a lifting cylinder as a vertical movement drive component has a large load-bearing capacity and stable lifting performance, which can meet the handling needs of goods of different weights. The structural design of the square tube and the channel steel increases the rigidity of the vertical movement mechanism, improves its stability during the handling process, and extends the service life of the equipment.

[0012] Preferably, the bottom end of the vertical moving mechanism is connected to the rotating mechanism through a connecting plate, and a handling tool is installed on the rotating mechanism mounting position. The connecting plate is a circular plate, and the rotating mechanism is mainly composed of a slewing bearing and a rotating drive unit. The rotating mechanism is installed at the bottom of the vertical moving mechanism and is fixedly connected to each other through the connecting plate. The rotating drive unit is a motor, and the motor drives the rotating mechanism to rotate. The rotating mechanism can be connected to a variety of handling tools, thereby driving the movement of the goods. The motor is fixed to one side of the slewing bearing through a flange. This connection method makes the connection between the rotating mechanism and the vertical moving mechanism more secure, can withstand greater torque, and ensures the stability of the rotation process. The rotating mechanism can be connected to a variety of handling tools, which greatly improves the versatility and flexibility of the equipment, can adapt to the handling needs of goods of different shapes and sizes, and improves work efficiency.

[0013] Preferably, the transverse plate is provided with a screw fixing seat on the other side of the guide groove, the screw fixing seat is fixedly connected to the screw, and one end of the screw is connected to the transverse drive assembly. A number of mounting holes are provided on both the transverse plate and the support platform, and the screw fixing seat is fixed to the upper surface of the transverse plate by bolts. The setting of the screw fixing seat provides stable support for the screw, ensuring that the screw does not shake during rotation, thereby improving the accuracy and stability of the transverse plate position adjustment. The design of the mounting holes facilitates adjustment of the position of the screw fixing seat according to actual needs, increases the adjustability and adaptability of the equipment, and can better meet the handling requirements under different working conditions.

[0014] Preferably, a screw support seat is provided on the support platform, a screw hole is provided in the center of the screw support seat, and the screw passes through the screw hole and is slidably connected to the screw support seat. The screw support seat is fixed to the upper surface of the support platform by bolts, and the transverse plate and the two support platforms are located on the same horizontal plane. The provision of the screw support seat further enhances the stability of the screw, prevents the screw from bending or deforming during long-term use, and extends the service life of the screw. At the same time, this structural design enables the transverse plate and the support platform to be on the same horizontal plane, ensuring the balance and stability of the entire device and improving the safety and reliability of the handling process.

[0015] Preferably, the wing mechanism includes a J-shaped plate assembly, and the curved portion of the J-shaped plate assembly is arranged upward in the sliding groove of the mounting frame. The design of the J-shaped plate assembly enables the side shift mechanism to better cooperate with the mounting frame, thereby improving the stability and reliability of the side shift mechanism. The arrangement with the curved portion facing upward can better withstand lateral forces, prevent the goods from shifting or tipping over during transportation, and improve the safety of transportation. The side of the mounting frame away from the rotating mechanism is fixed to the fixed beam of the forklift. The fixed beam is a channel steel, one side of which is fixed to the mounting frame, and the fixed beam is fixed to the fork frame of the forklift.

[0016] Preferably, a T-shaped plate is provided on one side of the J-shaped plate assembly, with the top end of the T-shaped plate extending outward from the J-shaped plate assembly to connect to the lateral shift drive assembly. One end of the lateral shift drive assembly is fixed to the upper surface of one end of the mounting frame. The T-shaped plate provides a stable connection point for the lateral shift drive assembly, ensuring that the lateral shift drive assembly can effectively drive the J-shaped plate assembly for lateral shifting. This connection method makes the lateral movement of the wing mechanism smoother and more reliable, enabling precise lateral shifting operations and improving the handling accuracy and flexibility of the equipment.

DETAILED DESCRIPTION

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0025] In the field of modern logistics and industrial production, the efficiency, flexibility and safety of cargo handling operations are of vital importance. Traditional handling equipment often has a single function and is difficult to meet the increasingly diverse material handling needs. The multifunctional lifting attachment of the present invention has come into being. The present invention provides a multifunctional lifting attachment for a forklift. By setting a rotating mechanism 6 and its mounting position 6.2, tools suitable for various cargo handling can be installed on the mounting position 6.2, thereby fixing the cargo and realizing multifunctional operations such as forking or clamping, meeting the diverse material handling needs. The multifunctional lifting attachment can move in multiple directions, left and right, front and back, up and down, and rotate 360°, making it more convenient to carry and place the cargo. All important parts can be disassembled to reduce after-sales costs.

[0026] In large logistics warehouses, there are a large number of goods of different shapes, sizes and weights that need to be transported and stored. In the warehouse, there are not only bulky mechanical equipment, but also irregularly shaped electronic products, and heavy building materials. The ordinary forklift attachments used in the past often seem to be unable to cope with such a variety of goods. For example, when transporting mechanical equipment, it is impossible to accurately fix the goods, which can easily cause the goods to shake or even fall during the transportation process; when transporting electronic products, there is a lack of suitable clamping tools, and there is a concern about damage to the products. The multifunctional lifting attachment of the present invention provides an effective way to solve these problems.

[0027] like Figure 1 and Figure 2As shown, the multifunctional lifting attachment is mainly installed on the fork frame of the forklift, and its core structure includes a mounting frame 1. A side shift mechanism 2 is cleverly provided in the mounting frame 1, which enables the attachment to move flexibly in the left and right directions, providing the possibility for precise positioning during the transportation process. A transverse platform 3 is installed on the side of the mounting frame 1, and a transverse mechanism 4 is carried on the transverse platform 3. Through the transverse mechanism 4, the attachment can be moved in the front and back directions. On the transverse mechanism 4, a guide groove 4.4 is provided in which a vertical movement mechanism 5 is installed, and the vertical movement mechanism 5 is responsible for the movement of the attachment in the up and down directions. At the bottom end of the vertical movement mechanism 5, a rotating mechanism 6 is installed, and a mounting position 6.2 is provided at the bottom end of the rotating mechanism 6. This mounting position 6.2 is the key to realizing multifunctional operations. Various types of applicable handling tools 9 can be installed according to the handling requirements of different goods.

[0028] The two ends of the transverse platform 3 are connected by a support platform 3.2 and a transverse drive assembly 4.5. The two ends of the support platform 3.2 adopt a U-shaped plate structure. The top and bottom ends of the U-shaped plate are firmly fixed to the upper and lower surfaces of the channel steel 3.1 by bolts. The transverse platform 3 is composed of two channel steels 3.1. The two channel steels 3.1 are set opposite each other with their openings facing inward, and one end is fixed to the mounting frame 1. They are symmetrically distributed on the same horizontal plane. The lower surface of the fixed end of the two channel steels 3.1 and the mounting frame 1 is provided with an L-shaped stabilizing plate. One end of the stabilizing plate is fixed to the surface of the mounting frame 1, and the other end is fixed to the lower surface of the channel steel 3.1. The channel steel 3.1 is set perpendicular to the mounting frame 1.

[0029] In actual handling operations, this structural design has demonstrated excellent stability. Taking the handling of large mechanical equipment as an example, the weight of the equipment can reach several tons. When the traditional transverse platform 3 bears such a large load, it is easy to shake or even deform. The transverse platform 3 of the present invention, through the bolt connection between the U-shaped plate and the channel steel 3.1 and the support of the stabilizing plate, can steadily carry the goods, ensuring that the transverse platform 3 will not shake during the handling process, greatly reducing the risk of goods falling. At the same time, the bolt connection method makes disassembly and installation very convenient during equipment maintenance. Compared with fixing methods such as welding, the time for disassembly and installation of the transverse platform 3 is shortened, greatly reducing maintenance costs and time.

[0030] In the multifunctional lifting attachment of this invention, a motor mounting plate 3.4 is fixedly mounted on the screw support base 3.3 near the support platform 3.2 of the mounting frame 1. This motor mounting plate 3.4 plays a crucial role, not only providing a stable mounting base for the motor but also ensuring its stability throughout operation. The motor is securely fixed by motor mounting plate 3.4 and precisely connected to the screw 4.6, ensuring efficient power transmission and precise control.

[0031] The motor serves as the power core of the entire transverse mechanism 4, and one end of the motor is cleverly connected to the reducer 4.8. The addition of the reducer 4.8 allows the output speed of the motor to be reasonably adjusted according to actual needs, thereby achieving precise control of the moving speed of the transverse plate 4.1. This design not only improves the flexibility of transportation, but also can flexibly adjust the transverse speed according to different cargo weights and transportation requirements, ensuring the smoothness and safety of the transportation process. In addition, the reducer 4.8 can also effectively reduce the load on the motor, extend the service life of the motor, and at the same time reduce noise and vibration during equipment operation, providing operators with a more comfortable working environment.

[0032] like Figure 1 As shown, the transverse mechanism 4 includes a transverse plate 4.1, and a plurality of pulleys 4.2 are provided at both ends of the transverse plate 4.1 through a mounting plate 4.3. The pulleys 4.2 and the mounting plate 4.3 are slidably arranged in the channel steel 3.1, which plays a good guiding role. The front and rear positions of the transverse plate 4.1 are adjusted by controlling the movement of the screw rod 4.6 by a motor. The setting of the pulley 4.2 makes the transverse plate 4.1 extremely smooth when moving. When transporting goods such as electronic products that require high handling accuracy, the operator can accurately control the movement of the screw rod 4.6 through the motor, thereby accurately adjusting the position of the transverse plate 4.1. For example, when transporting electronic products to designated shelves, the position error can be controlled within a few millimeters, which meets the high requirements for the placement of goods and greatly improves the handling efficiency and accuracy.

[0033] like Figure 2 As shown, the top of the vertical movement mechanism 5 is fixedly connected to a vertical movement drive assembly 5.1 mounted on the transverse movement plate 4.1 via a fixed plate. The vertical movement drive assembly 5.1 is fixed to one side of the guide groove 4.4 on the transverse movement plate 4.1. The guide groove 4.4 is provided on the upper surface of the transverse movement plate 4.1 and is a rectangular shell with upper and lower openings. The vertical movement mechanism 5 itself comprises a square tube 5.2, with channel steels provided on opposite sides of the square tube 5.2, with the openings of the two channel steels facing outward and facing away from each other. The vertical movement drive assembly 5.1 utilizes a lifting cylinder, which controls the vertical position of the vertical movement mechanism.

[0034] When transporting heavier goods such as building materials, the powerful load-bearing capacity of the lifting cylinder is fully demonstrated. Generally, building materials are heavy, and traditional lifting devices may not be able to stably lift them to the specified height. The lifting cylinder of the present invention can easily cope with this, and its stable lifting performance ensures that the goods will not get stuck or shake during the lifting process. The structural design of the square tube 5.2 and the channel steel greatly increases the rigidity of the vertical movement mechanism 5. During long-term use, after many experiments of transporting heavy objects, the vertical movement mechanism 5 can still maintain good performance, which extends its service life compared to ordinary structures and saves equipment replacement costs.

[0035] like Figure 3、 Figure 4 and Figure 5 As shown, the bottom end of the vertical moving mechanism 5 is tightly connected to the rotating mechanism 6 via a circular connecting plate 6.1. The rotating mechanism 6 is mainly composed of key components such as a high-precision slewing bearing and a high-efficiency motor. The motor is firmly fixed to one side of the slewing bearing through a flange, ensuring the stability and reliability of the entire rotating mechanism 6. The rotating mechanism 6 is cleverly installed at the bottom of the vertical moving mechanism, and the two are fixedly connected to each other through the connecting plate 6.1 to form an organic whole. During operation, the motor acts as a power source to drive the rotating mechanism 6 to rotate smoothly, and the rotating mechanism 6 can be flexibly installed with a variety of handling tools 9, such as forks, clamps, grabbing claws, etc., according to different handling requirements, thereby driving the precise movement of the goods.

[0036] In logistics warehouses, the handling and placement of goods often have complex and diverse requirements. Among them, it is often necessary to rotate the goods 360 degrees in all directions before placing them to meet different storage and transportation requirements. For example, when carrying some irregularly shaped goods, such as large mechanical equipment parts, special-shaped furniture, etc., it is often necessary to rotate the goods to find a suitable placement angle to make full use of the warehouse space and ensure the stable placement of the goods. The rotating mechanism 6 of the present invention can easily and efficiently achieve this function due to its unique design and excellent performance. During actual operation, the motor drives the slewing bearing to rotate smoothly, thereby driving the handling tool 9 and the goods installed on the rotating mechanism 6 to achieve precise and smooth rotation. The rotating mechanism 6 can not only withstand a large torque to ensure stability when carrying heavy objects, but also its rotation process is extremely smooth and smooth, and almost no shaking or jamming will occur, which greatly improves the safety and reliability of transportation.

[0037] By connecting with different handling tools 9, the rotating mechanism 6 of the present invention can widely adapt to the handling needs of various goods. Taking the handling of automobile parts as an example, due to the different shapes and characteristics of automobile parts, such as engine cylinders, car doors, etc., it is necessary to select the corresponding handling tools 9 according to the specific situation. In actual operation, the staff can quickly install the corresponding handling tools 9 according to the shape and size of the parts, such as installing special forks for engine cylinders and clamps for car doors. The rotating mechanism 6 can flexibly drive these goods to rotate, so that they can quickly adjust to the optimal handling posture during the handling process, thereby greatly improving the handling efficiency and adaptability. This multifunctional rotating mechanism 6 not only reduces the time and labor intensity of manually adjusting the angle of the goods, but also reduces the risk of damage to the goods due to improper manual operation, providing strong technical support for the efficient operation of logistics warehouses.

[0038] like Figure 1As shown, the transverse plate 4.1 is provided with a screw fixing seat 4.7 on the other side of the guide groove 4.4. The screw fixing seat 4.7 is fixedly connected to the screw 4.6, and one end of the screw 4.6 is connected to the transverse drive assembly 4.5. Several mounting holes are provided on the transverse plate 4.1 and the support platform 3.2. The screw fixing seat 4.7 is fixed to the upper surface of the transverse plate 4.1 by bolts. In actual application, the screw fixing seat 4.7 provides stable support for the screw 4.6. When the transverse plate 4.1 is subjected to a large force during the transportation of goods, the screw fixing seat 4.7 can ensure that the screw 4.6 does not shake, thereby ensuring the accuracy of the position adjustment of the transverse plate 4.1. The movement of the traverse plate 4.1 is driven by screw 4.6 and screw holder 4.7. For example, when transporting large furniture, the traverse plate 4.1 must withstand both the weight of the furniture and the impact of the movement. Screw holder 4.7 stably supports screw 4.6, minimizing the positional error of the traverse plate 4.1. The mounting holes are designed to allow the position of screw holder 4.7 to be adjusted according to the specific handling requirements. When transporting cargo of varying sizes, the position of screw holder 4.7 can be adjusted to optimize the force applied to the traverse plate 4.1, improving handling stability and safety.

[0039] A screw support seat 3.3 is provided on the support platform 3.2. A screw hole is provided in the center of the screw support seat 3.3. The screw 4.6 passes through the screw hole and is slidably connected to the screw support seat 3.3. The screw support seat 3.3 is fixed to the upper surface of the support platform 3.2 by bolts, and the transverse plate 4.1 and the two support platforms 3.2 are located on the same horizontal plane. The screw support seat 3.3 further enhances the stability of the screw 4.6. During long-term use, the screw 4.6 is easily bent or deformed by various forces when rotating. The screw support seat 3.3 can effectively prevent this from happening. In logistics warehouses with frequent handling, the screw 4.6 can still maintain a good condition after long-term use, extending the service life of the screw 4.6. At the same time, the design of the transverse plate 4.1 and the support platform 3.2 on the same horizontal plane ensures the balance and stability of the entire device. During the handling process, even if the ground is uneven, the safe handling of the goods can be ensured.

[0040] like Figure 2 and Figure 4As shown, the side shift mechanism includes a J-shaped plate assembly 2.2, and the J-shaped plate assembly 2.2 is arranged with its curved portion facing upward in the slide groove of the mounting frame 1. A T-shaped plate 2.3 is provided on one side of the J-shaped plate assembly 2.2, and the top end of the T-shaped plate extends out of the J-shaped plate assembly 2.2 and is connected to the side shift drive assembly 2.1, and one end of the side shift drive assembly 2.1 is fixed to the upper surface of one end of the mounting frame 1. In the present invention, the side shift drive assembly 2.1 is preferably a side shift cylinder. The side of the mounting frame 1 away from the rotating mechanism is fixed to the forklift fixed beam 7. The fixed beam 7 is a channel steel, and one side is fixed to the mounting frame 1, and the fixed beam 7 is fixed to the fork frame 8 of the forklift.

[0041] The wing mechanism plays an important role when transporting some large goods that are prone to lateral shifting. For example, when transporting a large refrigerator, the refrigerator tends to tilt to one side during transportation. The J-shaped plate assembly of the wing mechanism can withstand lateral forces and prevent the refrigerator from shifting sideways. The connection method between the T-shaped plate and the lateral shift drive assembly 2.1 makes the lateral movement of the wing mechanism smooth and reliable. The operator can accurately control the lateral shift distance of the J-shaped plate assembly through the lateral shift drive assembly 2.1 to achieve precise lateral shift operation. During the actual transportation process, the lateral shift accuracy can be controlled within a few centimeters, which greatly improves the handling accuracy and flexibility of the equipment and ensures that the goods can be safely and accurately transported to the designated location.

[0042] In actual operation, the multifunctional lifting attachments have demonstrated powerful functions. When mechanical equipment needs to be transported, a fork can be installed on the mounting position 6.2 of the rotating mechanism 6, and the mechanical equipment can be forked and transported to the designated position through the coordinated action of the transverse mechanism 4, the vertical mechanism 5 and the rotating mechanism 6. During the transportation process, the left and right positions of the goods can also be adjusted through the side shift mechanism 2 to ensure the accuracy of transportation. When transporting electronic products, install a clamp and use the clamp to gently fix the electronic products to avoid damage to the products. Through the flexible movement of each mechanism, the electronic products are transported to the shelf. During the transportation process, the rotating mechanism 6 can rotate 360° to adjust the angle of the electronic products so that they can better adapt to the placement requirements of the shelf.

[0043] The multifunctional lifting attachment of the present invention has all important parts that can be disassembled, and this feature brings great convenience to after-sales maintenance. When the equipment fails, maintenance personnel can quickly disassemble the damaged parts for repair or replacement. For example, when the motor of the transverse movement mechanism 4 fails, maintenance personnel can quickly remove the motor for repair or replace it with a new one by removing the bolts and other connecting parts. Compared with the integral structure, this detachable design greatly shortens the maintenance time and reduces the after-sales cost. In after-sales maintenance, the average maintenance time is shortened because the parts are detachable.

[0044] The multifunctional lifting attachment is a highly integrated piece of machinery. Its sophisticated mechanical structure and intelligent control system enable comprehensive cargo manipulation. The attachment is fixed to the forklift's fork frame with high-strength bolts. Its core components include a rotating mechanism 6, a vertical movement mechanism, a two-stage hydraulic cylinder system, a control selection mechanism, a screw drive system, and a side-shift cylinder. A variety of specialized handling tools 9, such as grippers, pushers, and rotators, can be quickly installed and replaced on the upper platform of the rotating mechanism 6 according to actual needs. These tools securely secure various types of cargo using hydraulic locking devices, ensuring safety during handling.

[0045] High-precision weight sensors and an intelligent alarm system are installed at key locations on the vertical movement mechanism. When the weight of the cargo exceeds the rated load, the system immediately issues an audible and visual alarm signal and displays the specific overload value on the control panel, effectively preventing equipment overload. The two-stage hydraulic cylinder system utilizes a double-acting hydraulic cylinder design, utilizing a proportional control valve to ensure smooth lifting of cargo. The lifting speed can be adjusted steplessly to suit the operating conditions.

[0046] The control selection mechanism is equipped with a high-torque servo motor and a high-precision 4.8-inch reducer, enabling continuous 360-degree rotation of the cargo within the horizontal plane, precise adjustment of lateral and rotational speeds, and a position memory function. The lead screw drive system utilizes a ball screw structure and is driven by a high-performance servo motor, enabling precise forward and backward movement of the cargo. The side shift cylinder utilizes a double-acting hydraulic cylinder design, coupled with a guide mechanism, for smooth left and right movement of the cargo.

[0047] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
