Bridge Cranes: Uses and Classification

Hook Bridge Crane

Features:  The lifting device is a hook or a ring. The working speed of the lifting mechanism can be adjusted by mechanical or electrical means as needed.

Uses:  It is suitable for general loading and unloading lifting operations in machining, repair, assembly workshops or warehouses, material yards. Cranes with adjustable speeds are used for precision installation in repair and assembly workshops or for slow - speed box closing in casting workshops.

Grab Bridge Crane

Features:  The lifting device is a double - rope grab (usually a four - rope grab). There are two sets of winch devices on the trolley, which can operate simultaneously or separately to achieve the lifting and opening/closing of the grab, as well as opening the grab and unloading materials at any height within the lifting height range.

Uses:  It is suitable for loading, unloading and lifting operations of bulk materials such as ore, limestone, sand, coke in warehouses, material yards, workshops and other places.

Electromagnetic Bridge Crane

Features:  The lifting device is an electromagnetic disk. It has a short loading and unloading time and requires fewer auxiliary personnel. However, the self - weight of the electromagnetic disk consumes power, and the lifting capacity varies with the nature, shape, and size of the items.

Uses:  It is suitable for lifting and transporting ferromagnetic metals and their products in mechanical, metallurgical factories and material yards. It is generally only used for attracting ferrous metal materials below 500℃.

Three - in - one Bridge Crane

Features:  On the bridge hook crane, there is a detachable motor grab and a detachable electromagnetic disk. The lifting device can be replaced according to the working object.

Uses:  It is suitable for occasions where the types of materials to be lifted often change and the productivity requirement is not very high.
