Abstract
A load handling system of an industrial vehicle includes a pantograph attachment that provides a variable reach. A sensor provides position feedback for the pantograph attachment. A processor then determines a maximum allowable reach of the pantograph attachment according to the position feedback and other vehicle operating parameters.
Claims21
A load handling apparatus of an industrial vehicle, the apparatus comprising:
- a rear section configured to mount to the industrial vehicle;
- an extending section configured to handle a load;
- an extension apparatus that horizontally extends the extending section from the rear section;
- a processor configured to calculate a maximum allowable horizontal extension of the extending section as a function of one or more vehicle operating parameters;
- a weight sensor that determines a load weight, wherein the maximum allowable horizontal extension of the extending section is reduced as the load weight increases;
- and
- a proximity device that detects a horizontal extension distance between the rear and extending sections to determine a position of the load, wherein the processor evaluates the position of the load and the one or more vehicle operating parameters to calculate the maximum allowable horizontal extension of the extending section.

A load handling system of an industrial vehicle comprising:
- a pantograph attachment providing a variable reach;
- a sensor indicating a position feedback of the pantograph attachment;
- and
- a processor that determines a maximum allowable lateral reach of the pantograph attachment according to the position feedback and one or more vehicle operating parameters, wherein the maximum allowable lateral reach is reduced when one or more of the operating parameters are increased, and wherein the maximum allowable lateral reach is increased when one or more of the operating parameters are decreased.

A load handling system of an industrial vehicle comprising:
- a pantograph attachment providing a variable reach;
- a sensor indicating a position feedback of the pantograph attachment;
- a processor that determines a maximum allowable lateral reach of the pantograph attachment according to the position feedback and one or more vehicle operating parameters;
- one or more vehicle sensors that transmit the one or more vehicle operating parameters to the processor;
- and
- a motor that extends or retracts the pantograph attachment according to an instruction from the processor, wherein the maximum allowable lateral reach of the pantograph attachment is determined by the processor in real time by comparing a vehicle stability profile stored in a memory with the vehicle operating parameters currently monitored by the vehicle sensors.
