Electric displacement drive of the crane bridge

This electric drive allows the drive to eliminate misalignments of the crane bridge and prevents the contact of the wheel flange and the rail head, which significantly extends the operational time of the wheels, rails, and also removes static and dynamic overloads arising from distortions of the crane.

The electric drive structure includes:

  • asynchronous squirrel-cage motor;
  • frequency converter;
  • tracking system;
  • position sensors.

Under the control of the servo system crane moves at the same distance to the rail heads on both sides, that is centered between the rails, which eliminates contact of rims and rail head. Actually, the distance between the rail head and flange constantly changes (due to the curvature of the rails), which is controlled by position sensors, but the control system calculates a motion path to avoid contact of the flange and the rail.

When the crane bridge unbalance is caused by various reasons (the slippage of wheels, the load on the crane bridge end beams is varied, non-simultaneous operation of the brakes, etc.) the operation system generates control signals in such way that the bridge of the crane moves perpendicular to the rails of the crane track.

During the movement of the crane this control system displays the distance measured by the position sensors between rims and rails of the crane wheels on a digital monitor.
