Electrical Control System
SYIC-2 integrated control system independently developed by SANY is adopted to ensure high system integration, accurate operation, and reliable quality. The control system mainly includes power system, engine system, master control system, load moment limiter system, auxiliary system, and safety monitoring system. Main electrical components are from internationally or industrially well-known brands with reliable quality, which can perform stably in such bad environment as in severe low or high temperature, plateau, and sandstorms.
The controller, monitor, and the engine communicates through CAN Bus.
Hydraulic System
Main pump: adopt large piston pump with open displacement to provide oil for the machine actuator;
Gear pump: dual gear pumps are used for swing, radiator and control circuit.
Control: the main pump adopt the control of electrical proportionate positive flow; winch motor is piston motor of variable displacement. The operation components are two hydraulic control handles, and one dual travel pedal control valve to control each actuator in proportionate way.
System max. pressure: Main load hoist, aux. load hoist, boom hoist winch and travel
system: 32MPa
Swing system: 20MPa
Control system: 4.5MPa
Hydraulic oil tank capacity: 460L
Swing Mechanism
Internal-gear swing drive can swing the upperworks by 360°.
Swing lock: Swing lock is designed. When the operation is over or the machine is in transport, the upperworks can be locked tightly.
Swing bearing: single row ball bearing.
Swing speed: 0-2.5rpm.
