In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0017] See also Figure 1-3 As shown, an embodiment of the present application provides a technical solution: a fixed safety belt suspension device for loading and unloading a truck, comprising at least two columns 110, a cross bar 120 cantilevered above the column 110, a steel wire rope 130 provided between the two cross bars 120, and a lifting mechanism 250 provided on the column 110, a pedal mechanism connected to the lifting mechanism 250, and the pedal mechanism can be lifted from the ground to the height of the truck under the action of the lifting mechanism 250.

[0018] In this way, the operator can stand directly on the pedal mechanism, and by pressing the start button, the pedal mechanism automatically moves upward under the action of the lifting mechanism 250, and moves directly to the top of the truck, making it convenient for the operator to board the truck.

[0019] Preferably, the pedal mechanism has a support portion 140 and a guide portion 150 arranged on both sides of the support portion 140, the support portion 140 is a rectangular structure composed of rectangular tubes, a plurality of support rods 141 are arranged in the middle of the support portion 140, the guide portion includes two parallel mounting rods 151 arranged on both sides of the column 110, a roller 152 is provided on the opposite side of the two mounting rods 151, and the roller 152 is installed on the baffle 153.
