Abstract
Disclosed is a lift device for lifting a container. The device includes a mount insert constructed to insert into and lock with a corner mounting block on the container. A carriage/trolley is attached to the mount insert, and includes a frame that defines a passthrough, a plurality of guide wheels attached to the frame that extend into the passthrough, and a lower pulley attached to the frame. A carriage/trolley vertical member is disposed in the passthrough, and includes a bottom end that contacts the ground, as well as a first upper pulley and a second upper pulley positioned away from the bottom end. A winch with a cable lifts the carriage/trolley. The cable exits the winch, spools on the first upper pulley, spools on the lower pulley, spools on the second upper pulley and connects to a cable anchor. The guide wheels ride along the carriage/trolley vertical member during lifting.
