Group hoist electric hoist, also known as building hoist electric hoist, welding can electric hoist, is a kind of multiple electric hoist for lifting professional together. A distinctive feature of the group hoist electric hoist is "stable". The "steadiness" of the group hoist electric hoist is mainly reflected in the slow rise speed. Compared with the fast electric hoist, the group hoist electric hoist has a very slow lifting speed, which is mainly to ensure that the lifting speed of multiple electric hoists is consistent. Only by maintaining a consistent speed can a true overall improvement be achieved without deviations, and even accidents of falling. The use of group hoist electric hoist is caused by the multiple chain electric hoist need the same model, the same tonnage, the same lifting height and the same lifting speed, only meet these several conditions, can you achieve synchronization in use Promote. However, the speed cannot be too fast, and the excessively fast speed is not easy to control, and it is also easy to tilt, leading to accidents. That's why the group hoist electric hoist is produced for this "stability".
