ESL series tube vacuum lifter for carton box stack or unloading was from 10kg up to 150kg maximum, and we can offer three standard control models for all applications:
This model we designed for one man operation with two hands, it feature its operation way like motorcycle drive model with high safety and convenient, the right hand with rotation lever for grabbing\lifting\low down, the left hand with brake lever for release and make the suction pads separated from the loads quickly, the loads never deviated from the pads unless the brake lever was pressed.
Up-Down control model: it was traditional model and most popular in applications.
The model designed for single hand operation with sensible up/down speed control, mainly for those smaller sized and 35kg below loads which need to be quick handle for stacking, machine feeding. The lifter integrated a quick release valve, which not only make the suction pads separated from loads while the loads had been well positioned and fully put down, but greatly enhanced the safety in the handling process
