PROJECT NAME: Suspended portal bridge crane VPMD 3,2 t / 7,06 m

INVESTOR: PK Ltd.

LOCATION: Dugo Selo

YEAR OF PRODUCTION: 2014

TECHNICAL CHARACTERISTICS:

• maximum crane capacity: 3,2 t
• bridge span: 7,06 m
• lift height: 5,158 m
• load lifting speed (frequency controlled): 5,2/0,9-0,4 m/min
• hoist travel speed (frequency controlled): 24/4-2,4 m/min
• bridge travel speed (frequency controlled): 24/4-2,4 m/min

TECHNICAL DESCRIPTION:

For the needs of investor, company PK Ltd., a detailed design of a suspended bridge crane was made. The maximum load capacity of the crane is 3,2 t, the bridge span is 7,06 m and the maximum lift height is 5,158 m. The crane was installed in the hall of company PK Ltd. in Dugo Selo.

The crane moves hanging from the crane tracks. The crane tracks consists of the existing honeycomb girders IPN340. The length of  crane tracks is 18 m.

All working movements of the crane: driving the bridge, driving the hoist and lifting / lowering the load, are electrically driven and controlled by frequency converters.

The crane is operated from the floor by a suspended cable pendant control station with reduced voltage.

The electrical equipment of the crane consists of:

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