Abstract

The gripping device has several pairs of jaws, positioned at equal intervals along the length of the sleeper to be lifted. The device has a central beam (6) with e.g. five crossbeams (8,10,12). Slotted links (72) between the crossbeams ensure equal spacing between them. Hooked clamp members with inward-facing jaws extend from the ends of the crossbeams and may be urged inwards by hydraulic fluid passing through flexible hoses (27,28).
