Abstract
A control system for a dump truck or trailer having a telescoping hoist is disclosed. The control system includes an integrated electronic control unit which receives sensor information regarding at least a hydraulic pump, a power take-off, a first inclinometer and a second inclinometer and uses this information to send warning to a user display and to sends control information to at least a hydraulic fluid control valve and optionally other devices on the truck or trailer as well.
Claims14
A control system for a dump truck or a dump trailer comprising:
- a truck or a truck trailer;
- a dump bed having a front portion, a rear portion, a bed floor and a plurality of sidewalls attached to the bed floor, the dump bed being pivotally attached to a lower portion of the truck or truck trailer;
- a dump bed hydraulic hoist comprising a plurality of telescoping hoist sections, the hoist having a first end attached to the truck or truck trailer and a second end attached to the dump bed, wherein the hoist is movable between a retracted position and an extended position in which the dump bed is tipped to facilitate load dumping;
- a hydraulic pump in flow communication with a hydraulic fluid control valve for supplying pressurized hydraulic fluid to the hoist, the pump further including a pump sensor for determining the operating state of the pump;
- a power take-off for selectively transferring power from a truck powertrain to the hydraulic pump, the power take-off having a valve to engage with and disengage from the hydraulic pump and further including a power take-off sensor for determining the operating state of the power take-off;
- a first inclinometer attached to the dump bed for determining a tip angle and a roll angle of the dump bed;
- a second inclinometer attached to the lower portion of the truck or truck trailer for determining longitudinal levelness and transverse levelness of the truck or truck trailer lower portion;
- an integrated hoist electronic control unit for receiving sensor information and sending control information based upon the sensor information received, wherein the control unit receives information from the pump sensor, the first inclinometer, and the second inclinometer, and wherein the control unit sends control information to the hydraulic fluid control valve;
- a primary hoist human machine interface capable of receiving information from and sending information to the control unit, the primary human machine interface having a video monitor for displaying information received from the control unit and a plurality of controls for sending information to the control unit.
