    摘要： A method and apparatus for reinforcing the training received by an operator of a material handling vehicle to maintain the operator's feet and legs in the operator compartment includes a first and second photoelectric beam extending across the entry to the compartment. When a deadman brake is released and the vehicle is commanded to move or is actually moving, the detectors sense the presence of objects extending through the entry. When objects are sensed, a vehicle brake can be applied, a visual or audio sensor can be activated, or the detected fault can be stored in memory. The faults can be used by a supervisor to calculate an operator rating.

    摘要： A mast includes a base section, an outer telescopic section and an inner telescopic section which are raised and lowered by a pair of main lift cylinders. A fork carriage is slidably mounted to the inner telescopic section and is raised and lowered thereon by a pair of free lift cylinders. The mast elements are arranged to form two mast columns which produce minimum obstruction to the truck operator's field of view when looking forward through the mast.

    摘要： A motorized pallet truck includes an angular indicator on the steering arm mechanism providing an internal controller with an angular position of the steering arm or tiller. The controller applies a brake when the tiller is in either of a substantially vertical or substantially horizontal position, limits the speed of the truck for a predetermined rotational movement from the vertical position, and allows full speed of the vehicle when the tiller arm is pulled into a predefined fast driving arc. The controller further limits the rate of acceleration of the truck when the truck is transitioned between a slow and a fast mode of operation to prevent rapid acceleration in the speed of the truck during the transition.

    摘要： A material handling vehicle includes first and second control handles positioned at opposing ends of an operator compartment. The control system receives inputs from each of the first and second control handles and determines an appropriate travel direction and speed based on those inputs. In a normal mode, one of the handles is in the neutral state, and the input of the second handle is therefore used to direct motion of the truck. In a conflict state, each of the first and second control handles is providing a non-neutral travel request, and the control system determines an appropriate travel direction and speed based on a most conservative choice algorithm.

    摘要： A hydraulic lifting and lowering system for battery-powered lift trucks includes an electronic control system which reduces or limits operator selected lifting commands in accordance with the current being drawn by an electric motor connected to drive a variable-displacement pump, and in accordance with the state-of-charge of the vehicle battery, to control a proportional valve which meters fluid flow to a lift cylinder.
