Through vertical circulation and double-layer lifting mechanisms, they can more than double parking capacity. These garages typically feature intelligent access control and integrated charging functionality.

[0004] In the existing technology, the lifting points of two-wheeled vehicle lifting frames are usually in the form of two or four multiple lifting points. When lifting the lifting frame, an independent lifting drive unit is usually set on each lifting frame, which increases the initial construction cost of the two-wheeled vehicle garage. Furthermore, when lifting through multiple lifting points, uneven force is easily generated, which can lead to the lifting frame tilting and two-wheeled vehicles falling, greatly increasing the danger factor of the two-wheeled vehicle garage. Summary of the Invention

[0012] A second ball head is fixedly connected to the side of the card plate away from the sliding plate, and a second pressure sensor is fixedly installed on the top of the steel frame structure. The second ball head contacts and squeezes the second pressure sensor.

[0013] Preferably, the lifting and limiting assembly includes multiple pulley bodies, all of which are fixedly connected to the second-layer vehicle platform. Each pulley body is rotatably connected to a limiting pulley. Multiple sets of U-shaped tracks are fixedly connected to the steel frame structure.

Each set of U-shaped tracks contains two tracks, and the limiting pulleys are located inside the corresponding U-shaped tracks.

[0014] Preferably, the walking assembly includes two rotating shafts, both of which are rotatably connected to a vehicle platform. Each rotating shaft is fixedly connected to a walking wheel, which is located at the top of the walking track. A second motor is fixedly installed on the vehicle platform.

[0016] Preferably, each of the vehicle carrier plates has two scrapers fixedly connected to it, both scrapers are located at the top of the travel track, and two travel wheels are located between the two scrapers.

[0017] Preferably, two wheel rails are fixedly connected to the top of both the first and second vehicle carriers, and two U-shaped frames are fixedly connected inside the wheel rails.

[0018] Preferably, each of the two-layer vehicle carrier plates is fixedly connected to a U-shaped baffle, and the movable pulleys are located inside the corresponding U-shaped baffles. Multiple buffer pads are fixedly connected to the bottom of each of the two-layer vehicle carrier plates.

[0019] A control method for a multi-level lifting and lateral movement two-wheeled vehicle garage, the method comprising the following steps:

[0020] Step 1: Push the two-wheeled vehicles onto multiple single-layer vehicle carriers for parking. Once the single-layer vehicle carriers are full, continue pushing the two-wheeled vehicles onto the second-layer vehicle carriers located on the ground. The steel wire rope is wound up using a steel wire winding assembly. During the winding process, the steel wire rope is limited by a fixed pulley assembly, and the movable pulley is lifted upwards. When the second-layer vehicle carrier is lifted upwards, the lifting limit assembly limits the second-layer vehicle carrier vertically.

[0021] Step 2: After the second-layer vehicle platform carrying the two-wheeled vehicle is lifted upward, the first-layer vehicle platform is driven by the walking component to move to the bottom of the second-layer vehicle platform carrying the two-wheeled vehicle and support the bottom of the second-layer vehicle platform carrying the two-wheeled vehicle. The wire winding component works in reverse to release the wire rope outward, so that the second-layer vehicle platform without the first-layer vehicle platform below moves downward to the ground.

[0022] Step 3: When retrieving the two-wheeled vehicle from the upper second-layer vehicle carrier, the steel wire rope is wound up by the steel wire winding assembly, so that all the second-layer vehicle carriers are moved to the top. The first-layer vehicle carrier is then driven to move laterally by the walking assembly until there is no second-layer vehicle carrier below the one where the two-wheeled vehicle needs to be retrieved. Then, the corresponding second-layer vehicle carrier is moved down to the ground to retrieve the two-wheeled vehicle.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. This invention synchronously drives multiple two-story vehicle platforms by winding and unwinding a single steel wire rope, reducing the number of lifting drive units required and lowering the investment cost of two-wheeled vehicle garages. Furthermore, when lifting the two-story vehicle platforms, a lifting limit assembly limits the platforms, and a single movable pulley performs single-point lifting, preventing uneven force distribution during lifting and improving stability. The cooperation between the fixed pulley assembly and the movable pulley halves the traction force required for lifting the two-story vehicle platforms, reducing power output during the lifting process.

[0025] 2. When the second-layer vehicle platform, which was originally located on the ground, comes into contact with the bottom of the crossbeam of the steel frame structure, the wire rope continues to be wound up. Since all the second-layer vehicle platforms are in a state where they cannot rise, the compression spring continues to compress. The pressure value of the first pressure sensor increases synchronously and reaches the set value. Then, the controller connected to the first pressure sensor controls the first motor to stop working, thereby completing the winding of the wire rope and ensuring that all the second-layer vehicle platforms are above the first-layer vehicle platform, preventing the lateral displacement of the first-layer vehicle platform from being blocked.

[0026] 3. When the last double-layer vehicle platform descends to the ground, the compression spring performs the second stage of reset and reaches the initial state. The clamping plate moves synchronously to the initial state, and the second ball head on the clamping plate contacts the second pressure sensor. After the second pressure sensor detects the pressure value, the controller on the second pressure sensor controls the first motor to stop working, thereby completing the release of the wire rope and ensuring that the wire rope no longer provides force support to any double-layer vehicle platform.

[0039] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0040] like Figures 1 to 11 The multi-level lifting and horizontal / vertical sliding two-wheeled vehicle garage shown includes a steel frame structure 1. On one side of the steel frame structure 1, there are multiple first-level vehicle-carrying platforms 2 and multiple second-level vehicle-carrying platforms 3. The number of second-level vehicle-carrying platforms 3 is one more than the number of first-level vehicle-carrying platforms 2. The multiple first-level vehicle-carrying platforms 2 are located at the bottom of the corresponding second-level vehicle-carrying platforms 3. The extra second-level vehicle-carrying platforms 3 are located at the bottom of the steel frame structure 1. Each second-level vehicle-carrying platform 3 is fixedly connected to a pulley shaft 4, and each pulley shaft 4 is rotatably connected to a movable pulley 5.

[0041] The top of the steel frame structure 1 is provided with a steel wire rope 6 and multiple fixed pulley assemblies. One end of the steel wire rope 6 passes through the corresponding fixed pulley assembly and the movable pulley 5 in sequence. The two ends of the steel wire rope 6 are respectively provided with a steel wire winding assembly and a spring limiting assembly.

[0042] The bottom of the steel frame structure 1 is fixedly connected to the walking track 7. Each of the first-layer vehicle platform 2 is equipped with a walking component. The walking component is used to drive the first-layer vehicle platform 2 to move laterally along the walking track 7. Each of the second-layer vehicle platform 3 is equipped with a lifting and limiting component.

[0043] Two-wheeled vehicles are pushed onto multiple single-layer vehicle carriers 2 for parking. Once the single-layer carriers 2 are full, the two-wheeled vehicles are pushed onto second-layer carriers 3 located on the ground. The steel wire rope 6 is wound up using a wire winding assembly. During winding, the steel wire rope 6 is limited by a fixed pulley assembly, and the movable pulley 5 is lifted upwards. As the second-layer carriers 3 are lifted upwards, a lifting limit assembly vertically limits their movement. The second-layer carriers 3 carrying the two-wheeled vehicles then... After being lifted, the first-layer vehicle platform 2 is driven by the walking component to move to the bottom of the second-layer vehicle platform 3 carrying two-wheeled vehicles, and supports the bottom of the second-layer vehicle platform 3 carrying two-wheeled vehicles. The wire winding component works in reverse to release the wire rope 6 outward, so that the second-layer vehicle platform 3, which does not have a first-layer vehicle platform 2 below, moves downward. The above operation is repeated until all the first-layer vehicle platforms 2 and second-layer vehicle platforms 3 are full of two-wheeled vehicles, and the last second-layer vehicle platform 3 with two-wheeled vehicles is in contact with the ground.

[0044] When it is necessary to retrieve a two-wheeled vehicle from the upper second-layer vehicle carrier 3, the wire rope 6 is wound up by the wire winding assembly, so that all the second-layer vehicle carriers 3 are moved above the first-layer vehicle carrier 2. The first-layer vehicle carrier 2 is then driven to move laterally by the walking assembly until there is no first-layer vehicle carrier 2 under the second-layer vehicle carrier 3 where the two-wheeled vehicle needs to be retrieved. Then, the corresponding second-layer vehicle carrier 3 is moved down to the ground to retrieve the two-wheeled vehicle.

[0045] This invention synchronously drives multiple two-story vehicle carriers 3 through the winding and unwinding of a single steel wire rope 6, reducing the number of lifting drive units required and lowering the investment cost of two-wheeled vehicle garages. Furthermore, when lifting the two-story vehicle carriers 3, a lifting limit assembly limits their movement, and a single movable pulley 5 performs single-point lifting, preventing uneven force distribution during lifting and improving the stability of the vehicle carriers 3 during the lifting process. The cooperation between the fixed pulley assembly and the movable pulley 5 halves the traction force required to lift the two-story vehicle carriers 3, reducing power output during the lifting process.

[0046] As a further embodiment of the present invention, the fixed pulley assembly includes a plurality of through slots 8, all of which are opened on the top of the steel frame structure 1. Each through slot 8 is fixedly connected to a mounting frame 9, and each mounting frame 9 is rotatably connected to a set of limiting pulleys 10, with each set of limiting pulleys 10 consisting of two pulleys.

[0047] One end of the wire rope 6 passes over the top of one of the limiting pulleys 10 in the same group and moves downward along the corresponding through groove 8. Then it passes over the bottom of the corresponding movable pulley 5 and moves upward along the corresponding through groove 8 before passing over the top of another limiting pulley 10 in the same group, thus completing the limiting of the fixed pulley assembly and the movable pulley 5. The above operation is repeated until the wire rope 6 passes through all the fixed pulley assemblies and the movable pulleys 5, so that when the wire rope 6 is wound up, it moves and pulls all the movable pulleys 5.

[0048] As a further embodiment of the present invention, the wire winding assembly includes a take-up drum 11, which is fixedly connected to the top of the steel frame structure 1. A take-up roller 12 is rotatably connected inside the take-up drum 11. A first motor 13 is fixedly mounted on the take-up drum 11. The output shaft of the first motor 13 is fixedly connected to the axis of the take-up roller 12. A wire feeding groove 14 is provided on the take-up drum 11. One end of the wire rope 6 extends along the wire feeding groove 14 into the interior of the take-up drum 11 and is then fixedly connected to the take-up roller 12.

[0049] The output shaft of the first motor 13 drives the take-up roller 12 to rotate in one direction. The take-up roller 12 is fixedly connected to one end of the wire rope 6, and the wire rope 6 is wound up on the take-up roller 12 along the wire feeding groove 14. When the output shaft of the first motor 13 rotates in the opposite direction, the wire rope 6 on the take-up roller 12 is fed out along the wire feeding groove 14.

[0050] As a further embodiment of the present invention, the spring limiting assembly includes a fixed sleeve 15, which is fixedly connected to the top of the steel frame structure 1. A clamping plate 16 is provided at one end of the fixed sleeve 15 away from the winding drum 11. Two limiting pins 17 are fixedly connected to the fixed sleeve 15, and both limiting pins 17 are slidably inserted into the clamping plate 16. The other end of the wire rope 6 passes through the inside of the fixed sleeve 15 and is fixedly connected to the clamping plate 16. A sliding plate 18 is provided between the fixed sleeve 15 and the clamping plate 16. Both limiting pins 17 are slidably inserted into the sliding plate 18. A compression spring 19 is fixedly connected between the fixed sleeve 15 and the sliding plate 18. A first ball head 20 is fixedly connected to the sliding plate 18. A first pressure sensor 21 is fixedly installed on the clamping plate 16. The first ball head 20 contacts and presses against the first pressure sensor 21.

[0051] A second ball head 22 is fixedly connected to the side of the card plate 16 away from the sliding plate 18, and a second pressure sensor 23 is fixedly installed on the top of the steel frame structure 1. The second ball head 22 contacts and presses against the second pressure sensor 23.

[0052] When the wire rope 6 is wound up, multiple second-layer vehicle carrier plates 3 rise simultaneously. At this time, the second-layer vehicle carrier plate 3 located on top of the first-layer vehicle carrier plate 2 moves upward and is in a suspended state, while another second-layer vehicle carrier plate 3 located on the ground simultaneously detaches from the ground and is located below the other second-layer vehicle carrier plates 3. All second-layer vehicle carrier plates 3 are in a suspended state. The force borne by the wire rope 6 is set as G. At this time, the tension of the wire rope 6 is G / 2. The wire rope 6 is fixedly connected to the clamping plate 16. Under the action of the tension of the wire rope 6, the clamping plate 16 moves along the sliding insertion of the limiting pin 17 towards the fixed sleeve 15 and squeezes the first ball head 20 on the sliding plate 18. At the same time, the movement of the sliding plate 18 causes the compression spring 19 to undergo compression deformation. The first pressure sensor 21 monitors the pressure value in real time by contacting the first ball head 20.

[0053] The second-layer vehicle platform 3 on top of the first-layer vehicle platform 2 rises first to the bottom of the crossbeam of the steel frame structure 1. The crossbeam blocks and restricts the second-layer vehicle platform 3 on top of the first-layer vehicle platform 2 from continuing to rise, while the second-layer vehicle platform 3 that was originally on the ground continues to rise. At this time, the tension of the wire rope 6 is also G / 2, and the value of the first pressure sensor 21 remains unchanged. When the second-layer vehicle platform 3 that was originally on the ground contacts the bottom of the crossbeam of the steel frame structure 1, the wire rope 6 continues to wind up. Since all the second-layer vehicle platforms 3 are in a state where they cannot rise, the compression spring 19 continues to compress. The pressure value of the first pressure sensor 21 increases synchronously and reaches the set value. Then, the controller connected to the first pressure sensor 21 controls the first motor 13 to stop working, thereby completing the winding of the wire rope 6 and ensuring that all the second-layer vehicle platforms 3 are above the first-layer vehicle platform 2, preventing the lateral displacement of the first-layer vehicle platform 2 from being blocked.

[0054] When the first motor 13 rotates in the reverse direction and drives the wire rope 6 to release the wire, all the second-layer car carriers 3 move downwards. The second-layer car carrier 3 located above the first-layer car carrier 2 descends to the top of the first-layer car carrier 2 and is supported by the first-layer car carrier 2. The compression spring 19 performs the first stage of elastic reset. One of the second-layer car carriers 3 is suspended without a first-layer car carrier 2 below it. At this time, the wire rope 6 still needs to bear the weight of the last second-layer car carrier 3, and the compression spring 19 cannot return to its initial state. When the last second-layer car carrier 3 descends to the ground, the compression spring 19 performs... In the second stage, after resetting and reaching the initial state, the clamping plate 16 moves synchronously to the initial state. The second ball head 22 on the clamping plate 16 contacts the second pressure sensor 23. After the second pressure sensor 23 detects the pressure value, the controller on the second pressure sensor 23 controls the first motor 13 to stop working, thereby completing the release of the wire rope 6. This ensures that the wire rope 6 no longer provides force support to any of the second-layer vehicle carrier plates 3, so that the first motor 13 and the wire rope 6 only participate in the work when the two-wheeled vehicles on the upper second-layer vehicle carrier plate 3 are picked up and parked, reducing the pressure-bearing time of the wire rope 6 and extending the service life of the wire rope 6.

[0055] As a further embodiment of the present invention, the lifting and limiting assembly includes multiple pulley bodies 24, all of which are fixedly connected to the second-layer vehicle platform 3. Each pulley body 24 is rotatably connected to a limiting pulley 25. Multiple sets of U-shaped tracks 26 are fixedly connected to the steel frame structure 1. The number of sets of U-shaped tracks 26 is the same as the number of second-layer vehicle platforms 3. Each set of U-shaped tracks 26 has two tracks, and the limiting pulleys 25 are located inside the corresponding U-shaped tracks 26.

[0056] During the lifting and lowering process, the second-layer vehicle platform 3 is limited by the U-shaped track 26 to limit the limiting pulley 25, so that the limiting pulley 25 rotates along the inside of the U-shaped track 26 through contact friction, thereby improving the stability of the lifting and lowering of the second-layer vehicle platform 3 and preventing the second-layer vehicle platform 3 from tilting.

[0057] As a further embodiment of the present invention, the walking assembly includes two rotating shafts 27, both of which are rotatably connected to a vehicle platform 2. Each rotating shaft 27 is fixedly connected to a walking wheel 28, which is located at the top of the walking track 7. A second motor 29 is fixedly installed on the vehicle platform 2. The output shaft of the second motor 29 is fixedly connected to a first sprocket 30 on one of the rotating shafts 27. A first chain 31 is driven between the two first sprockets 30. A second sprocket 32 ​​is fixedly connected to each of the two rotating shafts 27, and a second chain 33 is driven between the two second sprockets 32.

[0058] Both sides of the travel track 7 have limiting grooves 34. A fixed bracket 35 is fixedly installed on the first-layer vehicle platform 2. Two limiting rollers 36 are rotatably connected to both sides of the bottom of the fixed bracket 35. The limiting rollers 36 are rolled and limited in the corresponding limiting grooves 34. Multiple driven wheels 37 (such as...) are rotatably connected to the bottom of the first-layer vehicle platform 2. Figure 8 (as shown)

[0059] When the first-layer vehicle platform 2 moves laterally, the second motor 29 operates to rotate the first sprocket 30 on the output shaft. Through the transmission action of the first chain 31, the other first sprocket 30 drives the corresponding rotating shaft 27 to rotate. Through the transmission action of the second chain 33, the two rotating shafts 27 drive the corresponding traveling wheels 28 to rotate synchronously. During the rotation, the traveling wheels 28 drive the first-layer vehicle platform 2 to move laterally through the contact friction with the traveling track 7. When the first-layer vehicle platform 2 moves laterally, the multiple driven wheels 37 at the bottom rotate along the ground to ensure the normal movement of the first-layer vehicle platform 2.

[0060] When the first-layer vehicle platform 2 moves along the travel track 7, the multiple limiting rollers 36 on the fixed bracket 35 roll along the corresponding limiting grooves 34 to limit the movement of the first-layer vehicle platform 2, prevent the travel wheels 28 from leaving the travel track 7, and improve the stability of the displacement of the first-layer vehicle platform 2.

[0061] As a further embodiment of the present invention, two scrapers 38 are fixedly connected to each of the first-layer vehicle plate 2, and the two scrapers 38 are located at the top of the travel track 7, and the two travel wheels 28 are located between the two scrapers 38.

[0062] When the first-layer vehicle platform 2 moves along the travel track 7, the scraper 38 moves synchronously along the top of the travel track 7 and scrapes away dirt such as stones and fallen leaves on the top of the travel track 7, improving the smoothness of the rolling of the travel wheel 28 on the top of the travel track 7 and reducing vibration during displacement.

[0063] As a further embodiment of the present invention, two wheel rails 39 are fixedly connected to the top of the first-layer vehicle platform 2 and the second-layer vehicle platform 3, and two U-shaped frames 40 are fixedly connected inside the wheel rails 39.

[0064] When the two-wheeled vehicle is pushed onto the first-layer vehicle platform 2 or the second-layer vehicle platform 3, one of the wheels enters the interior of the wheel retainer 39 along the protrusion of the wheel retainer 39, and the wheel is limited by the two U-shaped frames 40, thereby improving the stability of the two-wheeled vehicle and preventing the two-wheeled vehicle from shifting.

[0065] As a further embodiment of the present invention, each of the two-layer vehicle-carrying plates 3 is fixedly connected with a U-shaped baffle 41, and each of the movable pulleys 5 is located inside the corresponding U-shaped baffle 41. Each of the two-layer vehicle-carrying plates 3 is fixedly connected with a plurality of buffer pads 42.

[0066] When the wire rope 6 moves on the movable pulley 5, the U-shaped baffle 41 protects and blocks the contact point between the wire rope 6 and the movable pulley 5 to prevent the wire rope 6 from falling off the movable pulley 5. The buffer pad 42 buffers the bottom contact of the second-layer vehicle platform 3 when it descends, reducing the shaking caused by the contact between the second-layer vehicle platform 3 and the first-layer vehicle platform 2 and the ground, and reducing the noise caused by the collision.

[0067] A control method for a multi-level lifting and lateral movement two-wheeled vehicle garage, the method comprising the following steps:

[0068] Step 1: Push the two-wheeled vehicle onto multiple single-layer vehicle platforms 2 for parking. When the single-layer vehicle platform 2 is full, continue to push the two-wheeled vehicle onto the second-layer vehicle platform 3 located on the ground. The steel wire rope 6 is wound up by the steel wire winding assembly. During the winding process, the steel wire rope 6 is limited by the fixed pulley assembly and the movable pulley 5 is lifted upward. When the second-layer vehicle platform 3 is lifted upward, the lifting limit assembly limits the second-layer vehicle platform 3 in the vertical direction.

[0069] Step 2: After the second-layer vehicle platform 3 carrying two-wheeled vehicles is lifted upward, the first-layer vehicle platform 2 is driven by the walking component to move to the bottom of the second-layer vehicle platform 3 carrying two-wheeled vehicles, and the bottom of the second-layer vehicle platform 3 carrying two-wheeled vehicles is supported. The wire winding component works in reverse to release the wire rope 6 outward, so that the second-layer vehicle platform 3 without the first-layer vehicle platform 2 below moves downward to the ground.

[0070] Step 3: When retrieving the two-wheeled vehicle from the upper second-layer vehicle carrier 3, the steel wire rope 6 is wound up by the steel wire winding assembly, so that all the second-layer vehicle carriers 3 are moved to the top. The first-layer vehicle carrier 2 is then driven to move laterally by the walking assembly until there is no second-layer vehicle carrier 2 below the second-layer vehicle carrier 3 where the two-wheeled vehicle needs to be retrieved. Then, the corresponding second-layer vehicle carrier 3 is moved down to the ground to retrieve the two-wheeled vehicle.

[0071] The component includes a fixed sleeve, a sliding plate, a compression spring, and a first and a second pressure sensor. When the wire rope passes through the fixed sleeve and engages with the sensor-equipped clamping plate and sliding plate, contact compression occurs. Through this structure, the system can monitor the tension and stress of the wire rope in real time. When the wire rope becomes slack, breaks unexpectedly, or the vehicle platform is abnormally overloaded, the deformation of the compression spring changes, instantly triggering the first or second pressure sensor to issue an early warning signal. This design achieves intelligent fall protection during the lifting process of the parking garage, greatly improving the safety and reliability of the automated parking system.

[0072] The second-level vehicle platform is equipped with pulleys and limiting pulleys. Multiple sets of corresponding U-shaped tracks are fixed to the steel frame structure, with the limiting pulleys located inside each U-shaped track. This guide structure provides strict mechanical control over the vertical lifting trajectory of the second-level vehicle platform. It effectively eliminates any lateral swaying or significant swinging that may occur during the suspension and lifting process, ensuring extreme stability and preventing parked two-wheeled vehicles from tipping over or colliding due to chassis vibration.

[0073] The first-layer vehicle carrier is driven by a second motor, with synchronous transmission via a first sprocket, a second sprocket, and a chain. The fixed bracket at the bottom of the first-layer vehicle carrier has rotating limiting rollers that roll and limit the movement within limiting grooves in the travel track. This design offers several advantages: the sprocket and chain transmission ensures synchronous rotation of the front and rear travel wheels, resulting in more even power output; the precise fit between the limiting rollers and the limiting grooves provides excellent lateral anti-deviation and guiding effects. This combination completely solves the technical problem of the first-layer vehicle carrier easily deviating or derailing during long-term lateral movement, ensuring precise alignment of the vehicle carrier during storage and retrieval.

[0074] Two scrapers are fixedly connected to a single-layer carrier plate, located at the top of the travel track, with both travel wheels positioned between them. The scrapers in front of and behind the travel wheels provide the carrier plate with a "self-cleaning" function. When the carrier plate moves laterally, the scrapers automatically push aside and scrape away dust, fallen leaves, or accumulated water from the travel track surface. This effectively prevents foreign objects from getting caught in the travel wheels, causing jamming, bumping, or slippage, ensuring the long-term smooth operation of the lateral movement system and reducing the manual maintenance costs of track cleaning.

[0075] The take-up drum is internally connected to a take-up roller, and a wire rope unwinding groove is provided on the take-up drum. The wire rope extends along the unwinding groove and is then fixed to the take-up roller. The design of the unwinding groove plays a role in forcibly sorting and physically limiting the winding and unwinding trajectory of the wire rope. Driven by the first motor, it ensures that the wire rope is neatly and orderly wound on the take-up roller, avoiding tangling, knotting, or overlapping of the wire rope inside, significantly reducing friction loss and extending the service life of the traction wire rope.

[0076] The second-level vehicle carrier has one more platform than the first-level one. This extra platform is located at the bottom of the steel frame structure. The bottom level has a single-level vehicle carrier equipped with a lateral movement mechanism. This scientifically designed ratio of upper and lower levels (with one space reserved for lateral movement and exchange), combined with the lateral movement of the first level and the lifting mechanism of the second level, achieves a highly efficient "no-obstruction" storage and retrieval logic. This not only maximizes the parking density of two-wheeled vehicles within a limited space but also optimizes the garage's scheduling mechanism, allowing users to retrieve their target vehicles without moving other vehicles, significantly reducing waiting time.
