Double hook electric hoist

Brief Introduction

The double-hook electric hoist means that there are two lower hooks on the same reel. This type of gourd drum is blank in the middle, and the rope is wound on both sides. And the often said double-rope electric hoist, generally refers to this, and more refers to the single rope on both sides. Double-hook and double-lifting point electric hoist on the market The so-called double-lifting point wire rope electric hoist refers to an electric hoist that has two lifting points separated by a certain distance and can rise or fall at the same time. The existing double-lifting point electric wire rope hoist has a hook and pulley device at each end of a wire rope electric hoist drum. This kind of double-lifting point electric hoist is composed of two sets of hook and pulley devices. The lifting or lowering of the cylinder can ensure that the two lifting points are raised and lowered at the same time; the other is to install the two electric hoist reducer ends relative to each other, and install the transmission gear and output shaft outside the reducer, using a coupling, an intermediate shaft The transmission of the two electric hoists is linked together to achieve the purpose of synchronization of the two electric hoists. The former type of double lifting point electric hoist is restricted by the length of the reel, which cannot meet the requirements of large lifting height and large distance between two lifting points; the latter has a complicated structure and requires a torque limiter, and the distance between the lifting points is large. Under circumstances, it is difficult to ensure the balance of the intermediate drive shaft, because the electric hoist swings during use, which causes the intermediate drive shaft to vibrate during operation.

The double hook electric hoist is suitable for lifting over-long workpieces or objects. The hook distance can be designed and manufactured according to user requirements.
