Abstract
A lifting device for lifting and tilting a refuse container includes a base, a drive unit mounted to the base and having a rotatable output shaft, a carriage for engaging and lifting the refuse container, at least one lift arm having a first end carried by the output shaft and a second end associated with the carriage, and at least one actuator arm having a first end pivotably carried by the base and a second end pivotably associated with the carriage. One of the lift arm or the actuator arm is pivotable at a location along the length thereof to allow movement of the carriage relative to the base and independent of rotation of the output shaft allowing movement of the carriage in response to obstacles or road debris so as to prevent damage to the lifter. In another embodiment, the carriage may include an upper portion carrying an upper hook and a lower portion carrying a lower hook where the lower portion is pivotable relative to said upper portion to allow movement of said lower hook relative to said upper hook independent of rotation of said output shaft.
