US Patent:

47476109, May 31, 1988

Filed:

Aug 20, 1987

Appl. No.:

7/087347

Inventors:

Bruce A. Yingling - Sleepy Hollow IL
Richard A. Peck - McHenry IL

Assignee:

Barrett Industrial Trucks, Inc. - Marengo IL

International Classification:

B66F 900

US Classification:

280 4312

Abstract:

A pallet sensing system, for a low lift pallet-type fork truck having load wheels extendible downwardly away from and retractable upwardly toward the forks to raise and lower the forks, is characterized by sensors for detecting proper alignment of the fork load wheels with respect to an opening in a bottom deck of a pallet. Upon the forks being extended into the pallet, the sensors disable lift controls of the truck to prevent the wheels from being extended away from the forks to lift the pallet until the sensors detect that the wheels are aligned for unobstructed passage through the bottom deck opening, whereupon the sensors enable the lift controls. The system prevents the pallet bottom deck from being broken by the wheels should an attempt be made to lift the pallet when the wheels are not positioned to pass freely through the opening, but would instead strike and break the bottom deck.

Abstract:

A barrier door for a protective enclosure includes a lower section and an upper section. The upper section includes an outer stationary portion and an inner movable portion disposed within the outer stationary portion. The outer stationary portion and the inner movable portion are light transmissive. The inner movable portion is movable in a vertical direction and is coupled to a lift device disposed in the lower section. The lift device is configured to move the inner movable portion between a lowered position in which the inner movable portion is at least partially withdrawn into the lower section to form an opening in the upper section and a raised position in which the inner movable portion is extended to close the opening.
