Heavy duty cabin control double girders electric bridge traveling crane

Product Description of QD Type double girder overhead crane

Double girder overhead crane is composed with double girder frame, crane traveling end truck, and the top running trolley with lifting and travelling device. The motors, reducers and brakes in this model crane lifting and traveling mechanism are separate parts, which makes the crane higher working duty from A3~A8 (ISO) and faster lifting and traveling speeds.

The cranes standard speeds are adjustable, which allow the crane adjust its speed under 2~3 grades. The crane could also be equipped with frequency inverter, which makes the crane speeds adjusted under 10 grades speeds. It could move very slow which makes it possible to do very accurate works.

This model overhead crane is designed under GB regulation, passed ISO, CE certification.

The crane lifting and travelling speeds are steady and accurate.

Main Features of QD model Crane:

1). Long Life Span: 30-50years;

2). Easy for Installation and maintenance;

3). Reasonable structure and strong rigidity;

4). The speed can be frequency inverter speed control;

5). Control method is cabin control or remote control;

6). Depending on lifting cargo, crane can be equipped with hanging beam magnet or magnet chuck or Grab or C hook;

7). Crane is equipped with all moving limit switch, loading limit and other standard safety devices, to promise crane work safe

Attention:

Safety is the most important issue for cranes. To ensure the safety,It is prohibited to use the equipment in the combustible, explosive or corrosives environment.(Need explosion proof type for this).
