Brakes

Service brake: double-circuit air

pressure brake, acting on all

wheels.Parking brake: spring energy

brake, acting on wheels of 2-7

axles.Auxiliary brake: engine

brake,transmission retarded brake,

and eddy current brake.

Safety devices

Hydraulic balance valve, Hydraulic relief valve, Double-way hydraulic valve, LMI. Spring centering system for control levers. Lowering limiter for preventing wire rope from over-releasing. Anti-two block at boom head for preventing wire rope from overwinding. Anemometer for measuring the wind velocity.

Hydraulic system

The variable displacement pump is connected to the PTO at the left side of transmission via propeller shaft fbr controlling the movements of electric-hydraulic proportional steering, outriggers and suspension. The triple pump is connected to the PTO at the rear of engine via propeller shaft for controlling the movements of hydraulic boosting and radiating hydraulic system

Electrical

System
