CONTROL AND HYDRAULIC SYSTEM FOR LIFTCRANE |
摘要 |
An improved control system for operation of a liftcrane having mechanical subsystems powered by a engine and connected thereto by a closed loop hydraulic system with one or more individual closed hydraulic loops. The liftcrane includes controls for outputting signals for operation of the mechanical subsystems and a programmable controller connected and responsive to the controls and connected to the mechanical subsystems. The programmable controller is capable of running a routine for controlling the mechanical subsystems. A first set of sensors is operable to sense the pressure in the closed loop hydraulic system at each of the mechanical subsystems in a first set of mechanical subsystems and provide an output to the programmable controller indicative of the hydraulic pressure sensed. A second set of sensors is operable to sense the position or speed of each of the mechanical subsystems in a second set of mechanical subsystems and provide an output to the programmable controller indicative of the position sensed.
