Description

Technical Field

[0001] The utility model relates to the field of airport equipment manufacturing, in particular to an anti-dropping device for a tail hook of a bulk truck used in an airport. Background Art

[0002] The bulk truck tail hook, also known as the coupler, is a key component at the rear of a bulk truck (a vehicle used to transport bulk goods, such as sand, gravel, etc.). Its main working principle is to connect a trailer, trailer or other additional load to the frame or chassis of the main vehicle through a special hook device fixed to the rear of the vehicle. The coupler usually consists of a metal rod and a ball connector. The metal rod is usually tightly connected to the chassis frame of the vehicle in order to withstand tension or torque. The ball connector is one of the key components of the coupler, which allows the coupler to rotate and tilt appropriately in multiple directions to accommodate the needs of the additional load.

[0003] When a vehicle needs to tow or haul an additional load, the coupler is used. The driver needs to align the coupler with the connection head of the additional load and ensure that the locking device is in a secure state. In this way, a secure physical connection can be established between the main vehicle and the additional load, effectively transferring the traction force to the additional load while maintaining stability and safety.

[0004] In general, the bulk truck tail hook is an important device for towing and hauling additional loads. It ensures the safety and efficiency of the bulk truck during transportation through the stability and adaptability of the connection.

[0005] Airport bulk trucks need to be used in an environment with several important equipment, so it is very important to prevent the tail hook pin from falling off. Utility Model Content
