PLATFORM-OPERATOR TILTING RESILIENT MOUNTING FOR EARTHMOVING VEHICLES

摘要

PLATFORM-OPERATOR TILTING RESILIENT MOUNTING FOR EARTHMOVING VEHICLES An operator's cab pivotally mounted to the frame of a tractor employing a screw jack for raising and positively and safely holding the cab in a raised position. When in a lowered operating position, the end of the cab spaced from the pivotal mounting is releasably secured to the frame by a pair of resilient mounting assemblies each including a first connector fixedly attached to the frame, a second connector fixedly attached to the cab, and a coupler having a body resiliently mounted to the first connector by means of a pin and resilient bushing and releasably secured to the second connector by means of a removable connecting pin. The weight of the cab is supported not by the removable connecting pin, but by mating bearing surfaces of the body and the second connector to facilitate removal of the pin. An upwardly projecting sloped surface of the first connector guides the body into supportive engagement with the mating surface thereof.
