Features multi-function electric hoist and how it works multifunction hoist (electric hoist) is a newly developed product, multi-hoist only has the main function of electric hoist and winch, and simplify the design of the structure, reducing the volume , convenient and practical, safe and reliable multi-purpose hoist Xinyu principle, is the latest development of new products. When the limit stopper baffle hit multifunction hoist winches, lifting automatically cease operations, such as reverse lifting rope, hoist motor will automatically stop working, hoist hook design is divided into dynamic and static loading loading two states, home use 220V power supply operation, the power cord for the plug-in, easy to use, hoist hook can be rotated 360 °. Multifunction hoist how to calculate the speed of multi-function electric hoist, also known as multi-functional machine, tonnage usually between 1.5T to 3 tons, we know that is different from the multi-function electric hoist winch, manual without electricity, although there is no electric fast but also very labor-saving, how to calculate the speed multifunction hoist is how much? 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 multifunctional hoist car, such as a hand-cranked winch 2T ratio of 20: 1, the roll diameter is 60mm, then the revolution of the trip is 3mm, by This can know the hand winch is probably faster. Multifunction hoist 220v, Sichuan multifunction hoist, lifting Xinyu Xinyu provided by Crane Co. Qingyuan. Qingyuan Xinyu Crane Co. (xyqz0312.1688.com) strong, credible, Baoding in Hebei engineering, construction crane industry has accumulated a large number of loyal customers.
