Jack solves waste problem
September 1st 2005

LGH Megalift and Mayfield Engineering solved a major lifting problem for Horstmann Group when it was contracted to manufacture and install two 40t rubbish processing vessels for a Tyneside waste processing station.

Each vessel had to be installed on two pairs of steel support legs, one being 8.5m high, the other 7.5m high. This gives the inclination needed to progress refuse down rotating vessels and over size-sorting screens. Vessels had to be positioned, side-by-side.

LGH Megalift supplied two 400t jacking systems. Mayfield removed the installed lower support legs and moved the first vessel into position under the first pre-erected LGH Megalift system that was attached to lifting points at each end of the vessel and extended to give some 4m clearance from floor level to the underside of the vessel.

The second LGH Megalift system was constructed beneath the vessel and extended to make contact with its underside. The first LGH Megalift was then disconnected and removed from the area.

The device was fully extended to about 8.6m, raising the vessel higher than the front support legs.

Once the front of the vessel was secured, the leading jacks were lowered, moved back close to the trailing jacks and extended to make contact with the vessel underside. Rear support legs were reinstalled and the vessel lowered onto them.
