Double Girder Double Trolley Overhead Crane Qe Model

Qe Model Double Girder Double Trolley Overhead Crane

Introduction

QE Type Double Girder Overhead Crane Working Class A5~A6 is suitable to lift long materials(wood, paper tube, pipe and bar) in workshops or outdoors to store in factory and mines. The two trolley could work separately and at the same time.

QE double girder overhead crane are mainly consists of Girder frame, Crane travelling device, two lifting trolley and electrical parts. Bridge adopts box welded structure, high degree of vertical and horizontal rigidity; crane travelling mechanism adopts separate drive. It has a strong beam and a stable travelling mechanism; the emergency switch can stop any movement once any dangerous happened. It is rely on the bridge frame along the workshop rail direction moving longitudinal, the trolley along the main beam direction moving transverse and the hook lifting movement to work. It is an excellent choice where high speeds and heavy service are required. As the widely used hoisting machinery currently especially is suitable for working at warehouses and freight yard and other department it is prohibited to use the equipment in the combustible, explosive or corrosives environment.

Main Features of QE model overhead crane

1). Long Life Span: 30-50 years;
2). Double welding box girder, beam deflection with DIN/FEM standard;
3). Trolley rail is made of high strength hot rolled flat steel (16 Mn);
4). The speed can be frequency inverter speed control;
5). Control method is cabin control or remote control;
6).Steel Material: Chinese standard Q235B and Q345B;
7). Both side of all the steel plate of crane are pretreatment by pretreatment production line,Sand blasting-- Primer spray--Primer
drying. Eliminate the innerstress of steel plate, increase the adhesive force of the steel structure. Ensure the appearance and
anticorrosion quality.

Technical Parameter

Feature

1, Two sets of heavy duty cart/crab on the double beam to lift material, cargo,etc together.
2, overhead traveling on the steel structure, normally in workshop, heavy working duty from A5-A6.
3, Soft start, 3-5 speeds to operate, very stable to lift and running.
4,Strong box type steel structure.
5, Six direction action, to make sure the enough wide working area.
6, Full safety system as follows:
Weight overload protection
Emergency stop system
Over current protection,Short-circuit protection
Phase sequence protection
Zero position protection
Voltage loss protection
Limit switch and stopper for crane long traveling and cross traveling
Lifting overhigh and overlow limit switch
