Benefits of technology
The solution provides a secure and controlled method for loading and unloading, reducing relative movement and eliminating safety hazards by ensuring the chain remains engaged with the sprocket, thus preventing slippage and ensuring safe operation.
Problems solved by technology
This simple approach has many limitations and there are many patents disclosing devices that simplify the procedure and / or improve the safety aspects of such a maneuver.
While the tiltable bed and interlocking bracket and cavity aspect of this patent appear to address deficiencies that are present in the previously described patents, it still suffers from the potential that the cable may come off the bracket, and therefore, could potentially be a safety hazard.
It is often difficult to maintain adequate control of this maneuver, and thus inadvertent lateral movement and slippage of the pulling mechanism can occur, especially during the initial lifting procedure.

Embodiment Construction
[0051] Referring to FIGS. 1 and 2, an apparatus according to a first embodiment of the invention is shown generally at 10 and connects a movable frame 11 to a conventional cab and chassis vehicle 13 via a chain 66, the frame 11 having a load 100 securely mounted thereupon. The vehicle 13 has a chassis 9 and a stationary frame 19 securely mounted thereupon. The stationary frame 19 is a “skeleton body” and is secured to the chassis 9 by conventional means, and is arranged such that a front end of the frame is disposed towards the rear of the cab of the vehicle 13 and a rear end portion is disposed towards a rear end portion of the chassis 9.
[0052] The stationary frame 19 has a guide system mounted on the chassis 9 of the vehicle 13 and comprises a “skeleton-type” arrangement of rails 16. The rails 16 are positioned parallel to each other along the side of the chassis 9 and are shaped so as to allow efficient sliding and seating of the moveable frame 11 during loading and are coated w...

A loading apparatus for a vehicle, the apparatus having a first frame, a second frame having a chain mounted thereupon; and a locking system that is mounted on the first frame. The locking system has a drive wheel, a first arm member and a second arm member. The system is configured such that in a generally closed position, the chain engages the drive wheel in a first position, the drive wheel is connected to the arms; the arms are urged into the closed position. In a generally open position, the chain engages the drive wheel in a second position and the arms are urged into the open position by the second frame.
Description
CROSS-REFERENCE TO RELATED APPLICATION [0001] The present application is a division of U.S. patent application Ser. No. 09 / 493,478, filed Jan. 28, 2000, which is incorporated herein by reference in its entirety for all purposes.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to devices for loading and unloading containers and more particularly, to a chain locking mechanism for safely loading a movable frame onto a stationary vehicle. [0004] 2. Description of Related Art [0005] A conventional cab and chassis vehicle when used to transport loads usually comprises a frame and a device for pulling a movable frame from the ground up and over onto the vehicles' stationary frame, and guiding the frame into the loaded position. During normal usage, the movable frame supports a load which is transferred from the ground to the vehicle chassis via an arrangement of elevating booms and guide systems that are controlled by an operator. This simpl...
