Abstract
A linkage system for loading machines is mounted on two lift-arms (14) supporting a pallet-lifting fork or a bucket (22) at the ends of the lift-arms. The linkage system is so designed that when using a bucket (22) or pallet-lifting fork the linkage system will ensure that the bucket or lifting fork will take a substantially desired angular position as it is raised and lowered, without needing to make adjustments to the tilt-cylinder as the bucket or lifting fork is raised.
