    摘要: A personnel carrying vehicle comprising a self propelled, steerable body, a telescoping mast attached to and extending upwardly from said body, and a personnel compartment attached to the mast and provided with a rail member that extends from the mast and around the sides. A pair of gate members, which are pivotally attached to the rail member and to the floor of the compartment, are movable from a closed position to an open position wherein said gate members extend into the compartment. The mast extends upwardly and forwardly of the body at an angle of approximately five degrees to the top of the rail; this provides the operator with unobstructed access to anything above the top edge of the rail, and the forward tilt of the mast enlarges the upper portion of the compartment, near the waist of the operator, thus accommodating the operator comfortably without increasing the length of the vehicle; it also causes the center of gravity of the vehicle to move forward, toward the center of the vehicle, as the compartment is raised. The vehicle is driven by electric motors which are located under the operator compartment and attached to the drive wheels through gear trains to permit the floor of the compartment to be positioned as close to the ground level as possible. Control handles are mounted within the personnel compartment, with one handle controlling steering and the other handle controlling traction. Sensors ensure the operator's hands are on both control handles and both feet are properly positioned on the floor before the vehicle can be moved or the platform raised; this ensures a four point stance, providing for operator stability and that the operator's hands and feet are within the operator's compartment anytime the vehicle is being moved or during lifting or lowering operations. Gate interlock switches are provided to restrict or prevent travel of the vehicle under certain conditions. A load deck is provided on the body of the vehicle on the opposite side of the mast from the personnel compartment. Also, a load tray may be mounted to the telescoping mast to move vertically with the compartment. Rail guides may be mounted to the outside of the vehicle to facilitate entry into and operations within narrow aisles.

    摘要: A fork lift truck includes a fork level sensor located in the forks, away from the vertical mast of a lift truck for detecting the true level of the forks, and a vision system including a camera which may take several forms. In one form, a single camera is mounted in a housing which may be moved to a protected location vertically either by sliding in the carriage assembly, or by use of a parallelogram device. In another form, multiple cameras are employed where a second camera may either mounted above the first camera in the same housing or mounted between the forks. Alternatively, the first camera may perform multiple roles by being moved vertically from a first predetermined location below the bottom of the forks to a higher elevation a second predetermined location relative to the forks. A video display terminal, which shows the view observed by the camera, may also include a fork level indicator, a reticle for assisting in adjusting the vertical position of the forks, and an indicator showing the specific truck function selected by the operator.

    摘要: An improved switch assembly for use with a materials handling truck includes a pair switches that are conveniently placed in a natural position for actuation by an operator while walking along side the truck. The pair of switches are so placed on each side of a steering control handle to prevent inadvertent actuation and therefore inadvertent operation of the truck. One of the pair is operated by the thumb while the other is positioned to be operated by the fingers as the operator grasps the handle. A control circuit responds to the operation of both switches on one side to move the truck forward at a predetermined speed.

    摘要: An apparatus and method are provided for guiding a personnel carrying vehicle including a body with a pair of driven rear wheels and a pair of front caster wheels into a narrow aisle. A pair of guide rollers are mounted on each side of the vehicle and spaced between the front caster wheels and the driven rear wheels. A steering rail extends between the pair of guide rollers on each side of the vehicle and is curved inwardly towards the body. A guide rail is placed on each side of the narrow aisle for engaging the vehicle mounted rollers with the guide rails terminating in entry ends which engage the steering rails for entry of the vehicle into the narrow aisle. The vehicle is steered forward toward an aisle entrance to cause one of the forward guide rollers to engage one of the guide rails and one of the aisle entry ends to engage one of the steering rails. Continuing forward movement of the vehicle causes the vehicle to rotate about the engaged aisle entry end to align the vehicle within the aisle. Aisle rollers may be placed at the entry ends of the guide rails for engaging the vehicle mounted steering rails.

    摘要: A materials handling vehicle, such as a turret stockpicker, is provided with control circuits and hardware to allow an operator to control the vehicle from either a standing or seated position while providing all of the safety interlocks that ensure proper operation of the vehicle. All functions of the vehicle, including raising and lowering of forks and moving the vehicle, are affected by the operator's position. The switch associated with the operator's seat indicates whether the operator is in the standing or seated position, and the control of the vehicle is appropriately modified to conform to industry standards according to the mode selected from the operator. An electronic circuit is responsive to an operator actuated seat switch to control the mode of operation wherein, a) if the operator is standing, floor operated switches control the braking of the vehicle, with braking being applied upon release of either of said switches, and b) if the operator is sitting, a pair of pedestal switches must both be activated to permit selected operations of the vehicle and lift truck functions, and wherein braking is controlled by the operation of a pedestal brake switch.
