Products Details
1. Main girder
Be welded of steel plates, connected by high-strength precision bolt. There are sliding rail for trolley to travel upper the girder which is fixed on outrigger by hightension
precision bolt.
2. Outrigger
a.Consist of rigid outrigger and flexible outrigger, all connection points are connected by high-tension bolt
b. The ladder is used by operator to enter into cab or arriving at winch.
c.When the span>30m,there need a flexible leg aiming at reducing the lateral thrust the trolley has to the rail when the girder load objects.
3. Travelling mechanism
Consist of driving gear box and passive wheel box
