摘要： A straddle fork vehicle includes a generally rectangular frame structure with front and rear forklift assemblies positioned between a set of tread belts. The straddle fork vehicle is designed such that the frame may accommodate, or straddle, agricultural harvesting pallets between the set of treads in a passthrough through area beneath the frame as the vehicle progresses down a field row. Engine configuration and improved braking systems facilitate a safer construction and tighter turning radius.

摘要： An industrial vehicle includes a travel direction detector configured to detect a travel direction of the industrial vehicle, a vehicle speed sensor configured to detect a vehicle speed of the industrial vehicle, a travel direction determiner, an object detector, and a controller. The controller is set in a particular state when the vehicle speed of the industrial vehicle is equal to or higher than a first vehicle speed threshold value. In the particular state, even when a travel direction command is changed by the travel direction determiner, the controller recognizes that a traveling state of the industrial vehicle before the travel direction command is changed continues and the object detector operates based on the traveling state of the industrial vehicle before the travel direction command is changed.

摘要： A system for controlling an industrial truck with a drive portion including a traction drive portion, a steering portion, and a load portion, comprises a portable transmitting unit configured to be positioned away from the industrial truck. The system further comprises at least three transmitting and receiving units positioned in a predetermined spatial arrangement with respect to one another on the drive portion. An evaluation unit is provided that is configured to determine a position of the portable transmitting and receiving unit relative to the industrial truck by measuring signal propagation times. The industrial truck further comprises a control unit configured to send a control command for traction drive and/or steering if the relative position of the portable transmitting and receiving unit is located within a predetermined spatial region relative to the industrial truck.

摘要： An industrial vehicle includes a hydraulic brake device, a hydraulic load handling device, a first hydraulic circuit, a second hydraulic circuit, a pressure compensating circuit, and a controller. The controller sets an electromagnetic valve to a first position during operation of the load handling device. The controller sets the electromagnetic valve to a second position and controls an electric motor to drive a hydraulic pump when determining that pressure needs to be accumulated in a hydraulic accumulator based on a detection result of a detector. When the electromagnetic valve is at the second position, hydraulic pressure generated by driving the hydraulic pump is applied to a pressure compensating valve and produces a force acting in a direction to disconnect the hydraulic pump and an oil tank from each other, so that hydraulic pressure is generated in a first oil passage to be accumulated in the hydraulic accumulator.

摘要： A materials handling vehicle is provided comprising: a frame; wheels supported on the frame; a traction motor coupled to one of the wheels to effect rotation of the one wheel; a speed control element operable by an operator to define a speed control signal corresponding to a desired speed of the traction motor; a system associated with a steerable wheel to effect angular movement of the steerable wheel; and control apparatus coupled to the speed control element to receive the speed control signal, and coupled to the traction motor to generate a drive signal to the traction motor in response to the speed control signal to control the operation of the traction motor. The control apparatus may determine an acceleration value for the traction motor based on at least one of an angular position of the steerable wheel, a speed of the traction motor and a current position of the speed control element as defined by the speed control signal.

摘要： A multiple detection zone supplemental remote control system for a materials handling vehicle comprises one or more sensors capable of defining multiple contactless detection zones at least towards the front of the forward travel direction of a remotely controlled vehicle. The vehicle responds to the detection of objects within the designated zones based upon predetermined actions, such as to slow down or stop the vehicle, and/or to take other action, such as to perform a steer angle correction.
