ABSTRACT:
The invention relates to a load-handling vehicle fitted with load-handling forks in which the fork blades are slidably movable relatively to the carriage on which they are mounted from a load supporting extended position to a retracted position in which the blades will be disengaged from the load. The sliding motion of the fork blades is such that during a movement from the extended load supporting position to a retracted position, each fork blade slides through the carriage on which it is mounted. The sliding motion is preferably effected by a rack and pinion type mechanism driven by a hydraulic driving mechanism controlled from the vehicle.
