Company EECV in Rotterdam keeps expanding

2013 EECV in Rotterdam increased their transhipment of coal and installed a new Bucket Wheel Reclaimer with a capacity of 3,500 tonnes per hour. This is the 7th bucket wheel reclaimer at EECV with Hägglunds drive systems installed and it has been running successfully since then.

 

Versatility in use

Direct drives are ideal, not only for the bucket wheel itself, but for many of the main functions on a Stacker/Reclaimer. Their specific advantages and high torque capacity make them well-suited for heavy duty applications.

At EECV, Hägglunds direct drives are also installed for slewing and long traveling on some of the Stacker/Reclaimers; on three of the four older stacker/reclaimers the slewing drives have been changed to direct drives, replacing the electric motor with brake, gearbox and open gear stage. Today Hägglunds CB 840 motors with Bica brake successfully drive the pinions for slewing. The long travel drives on two of the bucket wheel reclaimers have been fitted with Hägglunds CA 50 motors.

Govert de Bruin, Mechanical Manager at EECV, says “These drive systems offer reliability and torque. They are low maintenance, have a long life span and we always receive excellent support.”

Long-term performance

In 1987 EECV installed the first Hägglunds direct drive on two of their apron feeders in Rotterdam. Since then they have installed direct drives on the remaining apron feeders, their bucket wheels, slewing drives, long travel drives and conveyor head wagons. Today some 150 Hägglunds direct drives can be found at EECV. In addition to the Hägglunds drive systems, the stacker reclaimers and unloaders are also equipped with Rexroth cylinders and power units. The cylinders range from relatively small, suitable for hinged lids, to massive units that hold the arms or jibs.
