Everyone knows that electric hoist is divided into ring chain electric hoist and wire rope electric hoist. Most types of electric hoist are in these two categories, but why are group hanging electric hoist separately? Next, we will introduce this special group hoist electric hoist in detail: Group hoist electric hoist is actually a kind of chain electric hoist, but because of its specialty, everyone is accustomed to call it group hoist electric hoist. This hoist is divided into climbing frame electric hoist and welding tank electric hoist, climbing frame electric hoist is a hoist commonly used in construction projects, and welding tank electric hoist is mainly used in large storage tanks, so this name It is also divided according to the use environment, but the functions and structures of the two gourds are the same in some senses, and the structural principles are also the same. The group hoist electric hoist is composed of three-phase disc brake motor and planetary gear reducer. Transmission principle: The rotation of the group hoist electric hoist motor is decelerated by the reducer, and the speed and power are output to make the electric hoist lower hook rise or fall. When the motor is powered off, the group crane electric hoist uses the hook of the hoist to stop the work by relying on the brake of the brake motor, and the heavy weight stops at a considerable position. Another special point of the group hoist electric hoist is that this hoist cannot be operated by a single unit, there must be multiple units working at the same time, and the whole hoisting is achieved through the same control system, so this is a special one that is different from the ordinary single electric hoist point.
