Abstract

According to the present invention there is provided a load sensing system for an aerial work apparatus, the system comprising: a support member (20) mountable on a load handling machine; a first support structure (32) having at least one end connectable to the support member; a second structure (16) supported on said first support structure at a location (34) spaced from said at least one end of the first support structure; load determining means (36) for determining the load applied to the first support structure (32) via the second support structure (34). In one embodiment, the first support structure (34) comprises a transverse beam supported on the support member (20) at its ends, the second support structure comprising a carriage (16) having a support pin (34) resting on a midpoint of the support beam (32).
