Abstract

An earth moving appliance comprises a chassis which may be moved along the ground and which has a turret mounted for rotation about an axis thereon. A jib is pivotally mounted on the turret and carries a working tool such as a bucket. A shield, which may be a blade or skirt, is connected to the chassis, and is movable relative thereto between a first position in which the shield bears against the ground and is disposed between the working tool and the chassis and the second position in which the shield is raised from the ground. The shield is curved and has a centre of curvature which is substantially on the axis of rotation of the turret, the radius of curvature of the shield is such that contact between the shield and the turret on rotation of the latter is avoided. The shield presents a stop surface to the working tool, so that when, for example, the working tool is a bucket the shield facilitates loading of the bucket with material.
