Self loading tipper trailer - with hydraulically powered winch under tipping frame to release load container

摘要

The trailer is provided with a tipping frame operated by a ram powered from the tractor hydraulic system. The load is slid onto the frame on guides and is raised and lowered on the inclined frame by a cable attached to a winch in the bottom of the fixed frame. The cable is taken over rollers at the top and bottom of the tipping frame. The winch is operated by a cam plate to which two rams are linked, at 90 deg. out of phase with each other, and with the rams eccentrically linked to the plate. The winch rams are also powered from the tractor hydraulic system.
