US Patent:

6883625, Apr 26, 2005

Filed:

Aug 7, 2002

Appl. No.:

10/213788

Inventors:

Allen T. Trego - Hampshire IL, US
John I. Koeper - New Bremen OH, US
Robert J. Henshaw - Newnan GA, US

Assignee:

Crown Equipment Corporation - New Bremen OH

International Classification:

B62D051/04

US Classification:

180 192, 180 193, 180334

Abstract:

Supplemental walk along control for walkie/rider pallet trucks is provided by supplemental controllers such as jog and coast release switches and/or twist grips (or other drive motor speed controllers) provided adjacent the base of load carrying forks. The supplemental controllers 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, the operators activate the coast release switches to release the coast mode and enable deadman brake mechanisms to brake the trucks and/or by plug braking with the twist grips. A steering direction detector 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 controls is disabled.

International Classification:

B62D 2520
B66F 906

US Classification:

180 8912

Abstract:

The motor compartment of a fork lift truck is modified so that the operator's feet extend into the space normally required by the motor compartment. A motor support structure is installed between the traction motor and the gear box which is connected to the steerable, powered wheel. The motor support structure occupies a smaller space than the traction motor itself, thus increasing the space available to the operator's compartment, at least in a limited vertical location adjacent to the support. With the traction motor out of the way, sufficient space for elevated pedals is provided, thus providing the operator ample space to operate the truck while seated. A battery compartment and hydraulic system of the truck are positioned adjacent to one another and ahead of the operator's compartment/motor compartment. In this way, the battery compartment and hydraulic system are positioned such that they are clear of the operator's compartment.

Inventors:

Robert Joseph Henshaw - Evanston IL

Steve Carlyle Billger - Celina OH

Assignee:

Crown Equipment Corporation - New Bremen OH

International Classification:

A47C 1300

US Classification:

297112

Abstract:

An improved operator's station includes an improved three position seat assembly which allows the operator to stand, perch or sit while maintaining the operator's eyes at essentially the same vertical level. The seat assembly includes a back rest, a seat that may be raised and lowered, and a movable shelf or perch positioned between the back rest and the seat. In a stand mode of operation, the seat is lowered and the shelf is raised; in a perch mode of operation, the shelf is lowered to provide a partial support for the weight of the operator; and, in a sit mode of operation, the seat is raised for substantially full support of the weight of the operator and the shelf is raised to be flush with the back rest. Two sets of foot pedals are provided in the improved operator's station. A first set of pedals is on the floor and includes a brake pedal and a power pedal.

US Classification:

187232

Abstract:

Each straddle arm of a lift truck is formed from a cylindrical section of steel pipe or tubing which is continuous in its circumference, to evenly distribute the torque which is transferred from a forwardly extending portion of the straddle arm to a mast assembly of the truck.
