Our rail-mounted container gantry cranes are designed as two-girder bridge. The steel construction of the gantry consists of the hinged post, the fixed post and the main girders with suspension. The hoisting rope reeving for the container hoisting gear is executed as a rigid rope-tower. This system enables swing-free travel in gantry and trolley direction, as well as with the slewing gear.
The lifetime of the wheels is limited by the wear of the wheel flanges. This wear is caused by off-track running of the wheels. Tolerances and temperature changes affect the amount of wear caused by off-track running.
The patented Kuenz solution allows for swivelling of the travel unit in the horizontal direction to compensate for any inclination of the travel unit. That means: all wheels are running on the track. Stabilizers on both sides of the travel unit make it possible for optimized transmission of the forces to the steel structure.
This solution enables a major wear-reduction of the wheel flanges, which means a significant increase in the lifetime of the wheels.
