TECHNICAL DESCRIPTION:

For the needs of investor, company Omega Ltd., a single-girder bridge crane was designed, manufactured, installed and commissioned. The maximum load capacity of the crane is 5 t, and the span of the bridge is 14,35 m, while the lifting height is 5,7 m. The crane is mounted in the production hall of the company Omega Ltd. in Breznički Hum.

All working movements of the crane: driving the bridge, driving the hoist and lifting / lowering the load, are electrically driven. The crane is operated from the floor by suspended cable pendant control station with reduced voltage.

The single-girder bridge crane consists of:

• steel structure, consisting of:
  • the main girder made as a box girder,
  • end carriages,
• electric driving hoist, and
• electric equipment.

The electrical equipment of the crane consists of:

• electric motor of the lifting mechanism with brakes,
• electric motors with brakes for driving a hoist,
• two electric motors with brakes for driving the bridge,
• control cabinet,
• limit switches for switching off the lift drive, the hoist drive and the bridge drive,
• cable pendant control station,
• main switches, and
• power and control cables within the crane itself.

At the ends of the crane tracks, steel bumpers were installed as safety against the crane falling off the tracks. In the same way, the movement of the driving hoist along the main crane girder is limited.
