Description

Technical Field

[0001] The utility model mainly relates to the technical field of equipment disassembly and assembly lifting tools, and particularly relates to a lifting tool convenient for disassembly and assembly. Background Art

[0002] The gantry of a pickup truck is a structure installed at the rear of the pickup truck compartment. It is usually made of metal and is shaped like a door frame, so it is named "gantry". Its main functions include the following aspects: Cargo fixation and protection: The gantry can be used to fix and protect the goods in the compartment, especially when transporting tall or long items (such as ladders, pipes, etc.). It provides a safe support point to prevent the goods from moving or tilting during transportation. Installation of additional equipment: The gantry is often used as a platform for installing additional equipment, such as work lights, toolboxes, winches, etc. This can improve the practicality of the pickup truck, especially in construction, maintenance, or off-road activities, etc.

[0003] During the installation process of the gantry, first, the gantry and tools need to be prepared: Check whether the gantry is in good condition and prepare the required installation tools. Then place the gantry in position: Multiple people cooperate to lift the gantry onto the pickup truck and align it with the fixed position. Finally, fix the gantry: Use bolts to fix the gantry to the pickup truck compartment. Ensure that all bolts are tightened to ensure the stability of the gantry.

[0004] The inventor found the following defects during the operation of specific embodiments:

[0005] The size and specifications of the gantry are made according to the rear space of the vehicle. The weights of gantries for different vehicles are different. When disassembling and assembling the gantry, multiple people need to work together to move it. Since most gantries are made of metal, the process of moving the gantry is relatively dangerous. Especially when the gantry is placed at the rear of the pickup truck, if the force is uneven, it is easy to cause hand injuries to the lifting personnel.

[0006] It should be noted that the above content belongs to the technical cognition scope of the inventor. Due to the vast and complex technical content in this field, the above content of this application does not necessarily constitute the prior art. Content of the Utility Model
