Group hoist electric hoist, also known as oil tank electric hoist, welding tank electric hoist is commonly used in the climbing frame of the construction engineering field, climbing mold lifting, large oil tank group hoist. The essence of group hoist electric hoist lies in the word "group". The product is a low-speed driving electric chain hoist, which has the characteristics of slow lifting speed and stable operation. "Group" is used to denote a large number of objects, which is generally reflected in a large number of objects. The word "group" of the group hoist electric hoist is also interpreted in this way. In the group hoist electric hoist, many hoists are needed to hoist the same item together. The hanging things are generally bulky and heavy, usually not a hoist can be lifted. For example, oil tank, climbing mold, etc. The reason why the group hoist electric hoist can achieve such a function is to take advantage of its slow speed. Imagine how to ensure the stability and accuracy of lifting if 50 sets of electric hoist hoisting the same object when lifting the same object. If it is a group hoist electric hoist, can it be separated Use? The answer is yes, but in general, no one will use it, because its speed is much lower than other chain electric hoist, it may delay the progress of the project, if it is not used for group cranes, it is recommended Don’t choose. After all, the focus is now on high-efficiency work. The group crane and slow speed of the group crane electric hoist are mainly to ensure safety and the stability of synchronous lifting. When performing a single lifting, synchronous lifting is not involved
