摘要： A vehicle mounted hoist for loading, transporting and dumping containers including a tail frame pivotally mounted at a tail frame pivot pin to the rear of a vehicle; a jib assembly pivotally mounted to the tail frame at a jib assembly pivot pin forwardly of the tail frame pivot pin, the jib assembly including a telescopically extendable jib with an outboard end to which is connected a hook configured to engage with a complementary configured apparatus on a container; a pair of hydraulic cylinders connected between the vehicle and the jib assembly and operable to pivot the jib assembly about one of the pivot pins; and, a locking assembly connected with the tail frame and the jib assembly and having a locked condition wherein the jib assembly is locked to pivot as a unit with the tail frame about the tail frame pivot pin, and having an unlocked position wherein the jib assembly is unlocked from the tail frame and able to be pivoted about the jib assembly pivot pin, and wherein the locking assembly is operably connected with the jib so that complete retraction of the jib changes the locking assembly from the locked to the unlocked condition only when the first hydraulic cylinders are retracted and the jib assembly and the tail frame are both in a rest position lying substantially horizontal atop the vehicle.
