Description
technical field [0001] The invention relates to a belt lifter, in particular to a lower part belt lifter used for a side wall conveying line of an automobile body. Background technique [0002] In general, in the EMS conveying system for the inner and outer panels of the automobile manufacturing and welding factory, when the left and right side outer panels of the automobile are transported from the loading area to the unloading area by the EMS trolley, they can be lowered to the side of the vehicle through the elevator of this design. Install around the installation location of the main line. [0003] In the elevator unit of the EMS conveying system in the existing automobile production workshop, the form of the ground column next to the work station is generally used to realize the transformation of the workpiece from a high altitude to a certain pick-up height from the ground. Since the lift is erected on the ground and a safety fence is installed around the lift at the ...
