1. A system for loading and unloading a container from a transport vehicle comprising, in combination:
- a. a tilt frame member removably attached to a transport vehicle, where the tilt frame member has a length defined by a front located adjacent to a transport vehicle cab and a rear located opposite the front;
b. a carriage slidably attached to the tilt frame member that travels along the tilt frame member during loading of a container onto the transport vehicle;
c. a multi-stage central hydraulic cylinder having a fixed end and a moving end, the fixed end being attached toward the rear of the tilt frame member and the moving end is attached to the carriage such that extending and retracting the central hydraulic cylinder moves the carriage from the rear of the tilt frame member to the front of the tilt frame member and necessarily causes the container attached to the engaging means to be loaded onto the tilt frame member;
d. means for releasably engaging a container, where the engaging means is connected to and moves with the carriage along the tilt frame member when the central hydraulic cylinder is extended or retracted; and
e. a tail member rotatably attached to the tilt frame member, said tail member being rotated by at least one hydraulic or pneumatic cylinder; and
f. wherein said tail member can be rotated between a first position in alignment with said tilt frame member, and a second position adjacent the ground.

Abstract
A container handling system and method for a wheeled transport vehicle is disclosed that is capable of loading and unloading containers, particularly in locations where the overhead height is limited. A hinged tail member at the rear end of the elongated body (a/k/a tilt frame member) is rotated to the ground allowing the containers to be loaded and unloaded without rotating the tilt frame to its maximum height. A cable reeving arrangement, such as a dual reeving arrangement, can be utilized to load and unload the container.

4. A method for loading and unloading a container from a transport vehicle comprising, in combination:
-
a. providing a tilt frame member pivotably attached to a transport vehicle, where the tilt frame member has a front and rear, a carriage slidably attached to the tilt frame member, and a multi-stage central hydraulic cylinder connected to the carriage and having a fixed end and a moving end; b. providing a tail member pivotably attached to the rear of the tilt frame member and being actuated by at least one hydraulic cylinder; c. providing an engaging system on said carriage for connecting to a container; d. actuating pivotal rotation of said tail member; e. connecting said engaging system to a container; and f. activating sliding of said carriage member along said tilt frame member to assist in pulling a container along said hinged tail member and onto said tilt frame member until the container is fully positioned on the elongated body. - View Dependent Claims (5, 6, 7, 8)
