Note the use of multi-function electric hoist electric hoist is certainly easy to use, but there are aspects of the use of some noteworthy: 1. not stayed at the lifting, oblique lifting weights to avoid danger. 2. When lifting hoist, make sure to retain at least three turns of wire rope on the rope drum to prevent excessive force off the rope from the rope drum. 3.

Multifunction hoist how to calculate the speed of multi-function electric hoist, also known as multi-functional machine, tonnage usually between 1.5T 3 ton electric hoist, hoist multi-function we know that unlike electric winch, dual manual without electricity phase multifunctional electric hoist, although no electric fast but also very labor-saving, how to calculate the gain speed multifunction machine is the number? In fact, for multi-function electric hoist speed can not be determined, it can only be a range, shake it fast to run fast, run slow shake slow, generally used to measure the running speed ratio, a ratio well know Hand drum circle diameter can be calculated how much the trip meter electric hoist prices, such as a hand-cranked winch 2T ratio of 20: 1 electric hoist suppliers, roll diameter of 60mm, then turn around trip is 3mm, thus you can know the approximate speed of a hand winch.
