Abstract
A quick-coupling locking mechanism is provided comprising a C-shaped attachment means (2) which is secured to a service module (C) of any type and a toggle linkage assembly which is secured to a service vehicle (B). The C-shaped attachment means (2) is formed to define a lifting hook (3) at its top and a holding hook (4) at its bottom. The linkage assembly includes a horizontal lifting bar (5) for engagement with the lifting hook (3) and a horizontal holding bar (6) for engagement with the holding hook (4). The linkage assembly is selectively operable to move the lifting bar (5) into secure engagement with the lifting hook (3) to raise the service module (C) such that the holding hook (4) is brought into engagement with the holding bar (6). The linkage assembly further includes separating means (21) responsive to the movement of the assembly to force the lifting bar (5) away from the holding bar (6) to lock the lifting bar (5) and the holding bar (6) into secure engagement with the attachment means (2).
