QD A5-A7 Double-Girder Overhead Crane

Introduction to Double-beam Hoisting Trolley Bridge Crane

QD series double-beam hoisting trolley bridge crane consists of a box-shaped main beam frame, a crane operating device, a lifting hoisting mechanism, and a trolley. The trolley is equipped with a track on the main beam. When moving, a moving platform is installed on the outer side of the two main beams, one side is used to assemble and repair the crane moving device, and the other side is used to assemble the trolley operating device.

Application of QD hoisting trolley bridge crane

Hoisting trolley bridge crane is widely used in machinery manufacturing, metallurgical plants, steel industry, warehouses, material yards, power stations, etc. According to the lifting cargo, the crane can be equipped with a lifting beam magnet or an electromagnetic suction cup or a grab or a C-shaped hook, etc.;

Advantages of hoisting trolley bridge crane

■   The hoisting trolley is composed of an electric motor, a brake, a reducer, a trolley frame, a hook, a pulley, etc.
