  • Patent number: 8425177
    Abstract: A compact lifter is disclosed which allows for an improved operating envelope of the liftplate. The lifter utilizes a motor having 210 degrees of rotation and lifting arms of a unique geometry to rotate a liftplate from a retracted position below and in front of the lifter baseplate to a dumping position wherein the opening of a refuse cart is located substantially forward of an inner hopper or container edge. As a result, refuse is dumped further into the container or vehicle hopper, which minimizes the number of packing cycles required as multiple refuse carts are emptied. The liftplate is attached to the motor using dual lifting arms, and includes a fixed upper hook. A rotating, retractable lower hooking mechanism holds the refuse cart during dumping. The compact design improves ground clearance when the lifter is retracted, permits the dumping of large commercial containers over the lifter, and requires no modification of the hopper structure of a rear-loading refuse collection vehicle.
