摘要： A computer controlled braking system utilizes gross vehicle weight of a materials handling vehicle and maximum allowable vehicle speeds to calculate braking force in response to a service brake request. For vehicles equipped with a caster brake, the calculated braking force is proportionally distributed between a drive brake and the caster brake. The drive brake includes a mechanical brake and motor braking which is performed by a traction motor. The drive brake force is divided between the mechanical brake and the motor braking so that the motor provides as much braking as possible to reduce wear on the mechanical brake and also to conserve battery power. For vehicles equipped with a caster brake, the caster brake portion of the calculated braking force is determined as a programmable percentage of the total braking force and can differ based on travel direction. The caster brake portion is clipped and reverts to the drive brake if it is below a minimum; and, if the calculated caster brake force is greater than a maximum, the caster brake force in excess of the maximum is clipped and reverts to the drive brake. A maximum caster brake current can be set to accommodate different brake hardware. A user of the vehicle can select adjustments to the calculated drive brake force and, if provided, can also select independent adjustments to the calculated caster brake force. If the vehicle has not substantially stopped within a given period of time after having its speed reduced to a low speed, the mechanical drive brake is fully applied.

摘要： A handle (35) mounted generally horizontally on a fork lift truck for controlling forward and reverse speed of movement of the truck and raising and lowering forks is carried by a control device (100). The control device includes a shaft (150) with a centrally positioned spherical section (160) contained in a socket (172, 176) in a support member (170). The shaft is therefore free to rotate about the center (177) of the sphere. A ramp cam (200) is mounted on the support member surrounding the shaft. A slider (180) mounted on the shaft is pressed against the cam by action of a spring (190). This arrangement assures that the shaft and control handle remain centered until acted upon by an operator of the truck. Two linear potentiometers (270, 290) provide electrical output signals representing the X (horizontal) and Y (vertical) positions of the end of the shaft opposite the control handle. The cam is provided with four distinct compound surfaces (201-204). For vertical movement of the handle, the slopes of the two lower surfaces (202, 203) are greater than the slopes of the two upper surfaces (201, 204). The slopes of each surface are also different in the forward and reverse direction. This arrangement provides the illusion that the same force is required to move the handle in any direction. A detent (215) in the center of the cam requires a slightly greater force to move the handle from the center position.

摘要： A work assist vehicle (10) includes a self propelled, steerable body (20) having a chassis (24) and a drive mechanism (30) supported on the chassis; a mast assembly (40) coupled to the body; and, a personnel compartment (50) attached to the mast assembly and being movable by the mast assembly toward and away from the body. The body further includes a cover (80) adapted to extend over a portion of the chassis and a weight sensor assembly (90) coupled to the chassis and the cover. The weight sensor assembly is capable of detecting if someone or something is located on the cover.

摘要： An end of aisle control system permits an operator controlled materials handling vehicle to be configured by following instructions given on a vehicle-mounted service terminal (110) and easily positionable, vehicle-mounted magnet sensors (A1, A2, B1, B2, C1) to a customer's specific operating environment. In addition to end of aisle magnets (70) that are buried in specified paths in the floor of a warehouse, magnets may be buried in other paths to accomplish specified functions, such as auto-resume and end aisle blocked. The buried magnets identify zones of operation and a vehicle-mounted microprocessor (18) controls the maximum speed of travel in each of these zones. The maximum speed of the vehicle in each of the specified zones may be pre-selected according to the direction of travel of the vehicle, thus making the control system adaptable to a wide variety of operating environments. The end of aisle control system also controls the method of stopping the vehicle, either by the use of brakes, or by plugging the traction motor. Whenever the vehicle is stopped in response to action by the end of aisle control system, a vehicle- mounted audible (124) and visual (122) signal is presented, indicating that specific operator action is required before further movement in that same direction is possible.

摘要： A remote control device that is to be worn on the appendage of an operator includes a base portion, a wireless communication system, a control, and an insert member. The wireless communication system includes a wireless transmitter for transmitting wireless commands from the remote control device. The control is communicably coupled to the wireless communication system, wherein actuation of the control causes the wireless transmitter to transmit a wireless command. The insert member is removably attached to the base portion, wherein an opening for receiving an appendage of an operator is defined as either between the base portion and the insert member or by the insert member. The insert member is formed from an expandable material such that it may be stretched to increase the size of the opening.
