Abstract
A mobile load carrier comprises a castor mounting arrangement comprising two or swivellable castors mounted on a first member (7), characterized in that said first member (7) is rotatably attached to a second member or member (5), along a fixed, substantially horizontal axis (6) substantially perpendicular to the primary direction of travel of the mobile load carrier, said second member(s) (7) being attached to, or forming part of, the structure of the mobile load carrier, such that any movement of the castors' swivel axes, relative to the chassis, is synchronous, with movement only being possible via the rotatable attachment of the first member (7) to the second member(s) (5). Preferably the rotation is load dependent with the load dependency optionally being provided by one or more biasing members (10).
