Title:
SUPPLEMENTAL WALK ALONG CONTROL FOR WALKIE/RIDER PALLET TRUCKS
Document Type and Number:
WIPO Patent Application WO/2003/013943
Kind Code:
A1
Abstract:
Supplemental walk along control for walkie/rider pallet trucks (100) is provided by supplemental job switches (128, 130, 128A, 130A) and coast release switches (111) provided adjacent to the base of load carrying forks (106). The supplemental jog switches are enabled during coasting operation so that operators can advance to the base of the forks to accelerate the trucks between closely spaced picks located along substantially straight portions of pick routes. For application of the trucks' brakes (117), the operators activate the coast release switches to release the coast mode and enable deadman brake mechanisms (133) to brake the trucks. A steering direction detector (127) is provided to determine the direction of the steered wheel so that if the steered wheel is not directed substantially straight ahead, then operation of the truck from the supplemental jog switches is disabled.
