Abstract

A loading arm (50) has one end rotatably connected via journals (61, 63) to the loader frame (20). A tool attachment (70. 71) is pivotally connected to the other end of the arm and extends at an angle relative to the latter. A tilt linkage (80) for the tool is used to alter the angle of the tool relative to the arm and comprises a deflection lever (83) rotatably mounted on the loader frame independently from the arm via a journal (90), a linear actuator (81) extending between the frame and driven end of the actuator and a connecting part (85) rotatably secured to the driving end of the lever and extending in the direction of the tool. The tool is a scoop.
