WDH supplies cylinders for world’s largest backhoe dredger

Equipment & Technology // March 9, 2017

WDH tells Dredging News Online that the excavation system of the world’s largest backhoe, Royal Boskalis Westminster's Magnor, is equipped with 12 WDH cylinders.

In consultation with the client’s technical specialists, WDH came up with a customer-specific design. The double-acting hydraulic cylinders, with strokes ranging from 2m to 5m, are suitable for use in the most extreme conditions.

"It is a high-quality design with forged and casted parts instead of welded joints, because of better fatigue behavior. In addition, an extra bearing is placed in order to maintain stability," said WDH.

WDH also designed build the rotary joint, the interface between the vessel and digger.

In 2010, WDH had already supplied the hydraulic cylinders for Magnor’s predecessor, Baldur.
