HYDRAULIC SYSTEM

General

The task of the hydraulic system is to operate the ma- chine’s functions by means of hydraulic pressure and ßow. The system consists of hydraulic pump, tank, cooler, hydraulic motor, hydraulic cylinders, Þlters and valves of various kinds. Hoses or pipes connect the components with each other.

Valves are used to control the hydraulic system’s pressure, volume rate of ßow and direction. Pressure control valves limit or reduce the pressure to the value required. Volume control valves affect the hydraulic ßuid’s ßow and thereby the speed of the functions. Direction control valves direct the hydraulic ßuid to the machine’s different functions.

The hydraulic pump is of the variable displacement type and delivers a ßow of 0-65 l/min (0-17 gal/min).

Main pressure

The hydraulic system has two main pressures.

Standard pressure is 200 Bar.

Increased main pressure is 250 Bar.

Increased main pressure is used when the outriggers are down and when concrete cutters are used with increased tool pressure.

If concrete cutters with increased tool pressure are operated at the same time as another function, the machine returns to standard pressure.

Pressure cut-off

Functions equipped with pressure cut-off have a reduced pre-set maximum pressure. The telescopic arm is equipped with a pressure cut-off that produces a maximum of 180 Bar.

Cooler

The cooler has an integrated bypass valve that pro- tects against overpressure in conjunction with, for example, cold start.
