technical field

The invention relates to a tailgate of a car compartment, in particular to a steel wire rope vertically lifting tailgate which is applied to a truck to load goods into the compartment.

Background technique

In the modern transportation industry, in order to facilitate transportation, a kind of lifting and unloading equipment is often installed at the tail of trucks and various vehicles, that is, the tail plate of the car. By using this device, the efficiency of transportation and loading can be greatly improved, so the tail plate has become a modern logistics. One of the necessary equipment for transportation. The car tailgates that appear on the market at this stage are mainly of the flip type. Although it serves the purpose of assisting in carrying the goods onto the vehicle, its disadvantage is that because the tailgate is of the flip type, during its working process, The tail plate forms a certain angle with the ground, so there are certain defects. The current vertical lifting tailgate solves some defects of the flip-type tailgate, but the car compartment used has only one layer, and there are few goods in the pair, and if the car compartment has two layers, how to solve the two-layer car compartment? The problem of non-interference in the use of vertical tail lifts during loading and unloading.
