The main feature of the slow-speed loop chain electric hoist is that it can lift multiple units at once, which is its group lifting function. The lifting speed of the slow-speed group lifting electric hoist is 0.09 meters per minute, with consistent lifting speeds, allowing for simultaneous ascent and descent. Since multiple group lifting electric hoists are lifted simultaneously, if one or two do not achieve synchronization, customers can adjust them individually. Once they are adjusted to the same level, work can proceed. The main wear parts of the group lifting electric hoist are where the chains pass through, such as sprockets, idlers, gears, long shafts, short shafts, pulleys, etc. As long as the chains are properly cleaned, maintained, greased, and any accessories that malfunction are replaced promptly, this will also provide a good guarantee for the group lifting electric hoist. The group lifting electric hoist is controlled either uniformly by a control cabinet or individually.
