An arrangement for supporting lifting hooks for a mechanical handling device is described. Forks (not shown) are hooked over a rail 42 and extend down to rest against a lower bar 40. For each fork 20, the hook is located between the plates 48 or the plates 54, which form two carriages 46A, 46B. These can slide along the rail 42, drawing the forks with them. Movement of the carriages 46A, 46B is coordinated by racks 62A, 62B which extend from respective carriages 46A, 46B and mesh with a pinion wheel 64. Thus, the forks can be maintained symmetrically disposed about the centre line of the lifting apparatus, thereby improving safety of operation. |
