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.

A system for loading and unloading a container from a transport vehicle comprising:
- a. a tilt frame member pivotally attached to a transport vehicle, the tilt frame member having a length defined by a front end located adjacent to the cab of the transport vehicle and a rear end located at a distance from the cab;
- b. an engaging mechanism on the tilt frame member for releasably engaging a container and for assisting in loading and unloading containers from the tilt frame member;
- c. a first hydraulic system for moving said engaging mechanism along said tilt frame member;
- d. a tail member hingedly attached adjacent said rear end of said tilt frame member;
- and
- e. a second hydraulic system for hingedly rotating said tail member relative to said tilt frame member.
A system for loading and unloading containers from a transport vehicle comprising:
- an elongated tilt frame member rotatably attached to a transport vehicle;
- a dual cylinder reeving arrangement positioned on the tilt frame member for loading and unloading containers onto and off from a vehicle;
- and
- a hinged tail member rotatably attached adjacent the distal end of the tilt frame member;
- wherein said tail member can be rotated between a first position in alignment with said tilt frame member and a second position adjacent to the ground.
A system for loading and unloading containers from a transport vehicle comprising:
- an elongated tilt frame member rotatably attached to a transport vehicle;
- a single cylinder reeving arrangement positioned on the tilt frame member for loading and unloading containers onto and off from a vehicle;
- and
- a hinged tail member rotatably attached to a distal end of the tilt frame member;
- wherein said tail member can be rotated between a first position in alignment with said tilt frame member and a second position adjacent to the ground.
A method for loading and unloading containers onto a transport vehicle comprising:
- a. providing an elongated tilt frame member rotatably attached to a transport vehicle;
- b. providing a tail member pivotably attached to the rear of the elongated body by a pivot member and being actuated by at least one hydraulic cylinder, said tail member being rotatably between a first position in alignment with said tilt frame member and a second position adjacent the ground;
- c. providing a dual hydraulic cylinder reeving arrangement on said tilt frame member for connecting to containers, said reeving arrangement having a cable member;
- d. actuating pivotal rotation of said tail member to said second position;
- e. connecting said cable member of said dual hydraulic cylinder reeving arrangement to a container;
- f. activating said dual hydraulic cylinder reeving arrangement to assist in pulling a container up said tail member and onto said tilt frame member;
- and
- g. rotating said tail member to said first position.
