Abstract

The loading shovel comprises a driven chassis (1) on the upper part of which an arm (5) rotates on a horizontal axis (4) under the action of a hydraulic ram (7) connected to both the arm (5) and the chasis (1). On the end of the arm is a bucket (9). The arm consists of two separate elements hinged to each other on an axis (6) parallel to the arm base axis, the first (5a) of the two elements being attached to the hydraulic ram. A second hydraulic ram (8) is attached to both the second element (5b) of the arm and either the chassis or the first arm element. The unit is designed so that during loading operations the joining axis of the two elements is located below the joining axis of the arm to the chassis. The shovel is stable when moving, either with or without a load and the length of the arm enables a load to be discharged directly onto a vehicle.
