Abstract
A coupling device for a handling trolley comprises a drawbar (22) arranged at the front of the trolley and designed to co-operate with the hook (24) provided at the back of a tractor, in particular a trolley preceding a line of trolleys. The drawbar (22) comprises a longitudinal slot (36) wherein the hook (24) is designed to slide such that the hook can slide in the longitudinal slot between a position spaced apart wherein the trolley (10) is at a maximum distance from the tractor while it is being towed and a closer position wherein the trolley is at a minimum distance from the tractor to reduce the space requirement when it is stopped.

Coupling device for a handling trolley, comprising a drawbar (22) provided at the front of the trolley and designed to cooperate with a hook (24) provided at the rear of a towing unit, in particular a trolley in front in a line of trolleys, characterised in that the drawbar (22) has a longitudinal slot (36) in which the hook (24) is able to slide so that the said hook can slide in the said longitudinal slot between a spaced-apart position, in which the trolley (10) is at a maximum distance from the towing unit during towing, and a close-together position, in which the trolley is at a minimum distance from the towing unit so as to reduce the space requirement when stationary.
A trolley apparatus comprising;
- a first handling trolley having a front and a rear with a first drawbar (22) disposed at the front of the first handling trolley,
- a second handling trolley having a front and a rear with a second hook (24) disposed at the rear of the second handling trolley,
- characterised in that the first drawbar (22) has a longitudinal slot (36) and the first drawbar (22) articulates between a coupled position with the second hook (24) sliding in the longitudinal slot between a spaced-apart position, in which the first handling trolley is at a maximum distance from the second handling trolley, and a close-together position, in which the first handling trolley is at a minimum distance from the second handling trolley, and an uncoupled position with the second hook (24) removed from the longitudinal slot and spaced from the first drawbar (22).
A handling trolley comprising;
- a chassis (12) having a front and a rear,
- a drawbar (22) disposed at the front of the chassis with the drawbar (22) having a longitudinal slot (36),
- a hook (24) disposed at the rear of the chassis, and
- an articulation device mounted to the chassis and supporting the drawbar (22) on the front of the chassis with the articulation device defining an articulation axis (XX) for pivoting the drawbar between a coupled position substantially parallel with the chassis and an uncoupled position angled relative to the chassis.
