The ‘Chain type RotaDavit’ (Patent Pending) has been designed, manufactured installed and commissioned into service at Severn Trent Water – Ledbury STW by Lloyds – Rota division.

Its structure can be secured to existing steelwork or concrete and is fitted with its own integral chain hoist mechanism which is operated from the rear of the post.

The load chain which is fed from the rear of the post is confined within the arm structure and passes over a set of rollers and through a stripping box at the end of the arm. This is designed to remove debris which is present on the chain when a unit is lifted. The remaining load chain is stored in a collector/container bag which is secured to the hoist unit.

The SWL of the unit can be anything up to a maximum of 700 Kgs. The reach of the lifting point is adjustable up to a distance of 1200mm. There is potential for very fine adjustments on-site on the unit. The height can also be altered to suit any on-site requirement.

Under full load the unit can be slewed through 360 degrees with minimal effort and all of the operations of the hoisting unit is carried out from the safe side of the hand-railing.
