Load leveling modification for front loading refuse truck

摘要

A modification apparatus to convert an existing front loading refuse collection truck so that the lifted container remains level until the container is near the load opening of the refuse collection body of the truck. A mounting plate is bolted to brackets added to an existing refuse collection body and provides multiple connection points for attachment of one end of a slave cylinder that is hinged at its other end to one of the main lift arms of the collection body. As the rod of the slave cylinder extends or retracts with the movement of the lift arm, hydraulic fluid from the slave cylinder passes to fork cylinders which retract or extend to control the orientation of the lifted container relative to the lift arms. The apparatus can be easily added to a variety of existing front loading collection bodies.

主权项

1. A front end load commodity collection body comprising
lift arms driven by main hydraulic cylinders to lift a container supported on the lift arms from a ground position to a tipped position overlying a load opening of the body, the lift arms pivotable about pivots on opposing sides of the body, each of the main hydraulic cylinders hinged to a one of the opposing sides of the body and drivingly coupled to a one of the lift arms, a mounting member removably mounted to one of the sides of the collection body adjacent one of the main hydraulic cylinders, a slave cylinder mounted at a first end thereof to the mounting member, the slave cylinder hinged at a second end thereof to one of the lift arms wherein a rod of the slave cylinder extends or retracts in response to movement of the one of the lift arms, hydraulic ducts coupled to the slave cylinder and selectively coupled to leveling cylinders supported on the lift arms, the hydraulic ducts passing hydraulic fluid between the slave cylinder and the leveling cylinders when coupled thereto, rods of the leveling cylinders extending in response to hydraulic fluid received from the slave cylinder thereby maintaining an upright orientation of the container as the container is lifted.
