Install Double Girder Overhead Travelling Crane 20 tons

Main beam uses bias-rail box-type structure, with optimized design and light self-weight，Steel plate material Q345-B，It employs motor of hoisting mechanism and reducer imported. The integrated and compact design of hoisting motor, reducer, reel and limit switch saves space for the user. Modular design increases the reliability of mechanism meanwhile reduces the time and cost for maintaining.

It has more and faster hoist speed and various pulley ratio which can be selected. The standard traveling mechanism of trolley is controlled by converter, with speed of 20m/min which makes a little swing and accurate position if hoisting items while trolley traveling as well as lifts precision and valuable items reliably.

Double Girder Overhead Travelling Crane Feature：

1, Overhead traveling on the steel structure, normally in workshop, heavy working duty from A5-A8

2, Light self weight, could save steel structure cost.

3, Lifting and traveling is very accurate.

4, VVF/ frequency inverter control, 3-5 speeds to operate, stable to lift and running.

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 over-high and over-low limit switch
