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.
