Inquiry (采购产品): Hoist I am interested in a 500 lb capacity hoist with about 40' of travel (mono rail exists) with an 8' lift. The system is used to load parts into a jig and thus needs to have very smooth motion. The current system is very jerky and making a move of 1/8" is impossible. Do you have a system that can help? **** Hidden Message ***** Roger Richardson 30144 Company: Delta Sigma Corp E-mail: roger@deltasigmacorp.com **** Hidden Message ***** roger@deltasigmacorp.com
