20 ton QD Model Overhead Crane

Sketch

A brief of introduction

QD Model Hanger Bridge Crane mainly consists of bridge,trolley travelling mechanism,crab and electrical appliances,and is divided into 2 working grades of A5 and A6 according to the use frequency.

This crane operation is completed in driver's chamber.

Note:HO ≤250 refers to the increased height by trolley buffer.

Benefits and Features

1.Compact design, optimal use of the size of work areas

2.Control the load easily and position the load exactly

3.Superior safety and reliability

4.Minimum& Easy maintenance

5.“One-Stop Shop” for your crane and hoist needs

Safety and Facilities

1.Overload protection: If the material is over the capacity, the crane will give a sharp warning for protection

itself.

2.Emergency brake: If the operation staff encounter some emergency situation, we could start the emergency

brake system to protection the related treasure.

3.Control Method: Room control or remote control to avoid any injure to the operation staff

4.Main lifting motor: with thermal protection and currency protection.

The material

Molding, no welds, high-precision cold-formed molding, eliminating the traditional production grinding, cutting, welding,

and many other complicated production process, reduce to the deformation of the

single beam crane girder in the handling process, to ensure that a single beam

crane girder precision. Improve the work efficiency, while greatly enhanced the

whole strength, and improve the quality of cranes appearance.

Mechanical part

Double girder, welding box beam, camber meet national standard;

Adopt high quality carbon steel, Q235B or Q345B;

Main and end girder connected through level 10.9 high-strength bolt

Crane drive: IP54 or IP44, level F insulation

Efficiency brake, long life

Electric part

Security trolley line or angle steel trolley line

The power supply of Travelling trolley adopt flat cable

Smoothly sliding, overall nice

Controlling ways

Ground controlling and cab controlling

Operating cab: open style and close style, left or right installation

Direction of entrance: side, end and top

Choose according to customer's different requirement
