CHASSIS
HYDRAULIC SYSTEM
Load sensing, variable flow, automatically controlled feed, variable output
power and multi-function servo control with open centers. Auto warm up machine
(standard feature) provides maximum performance at low temperatures.
Pumps
Main pumps Two axial piston pumps
with variable displacement.
Maximum flow 2 x 214 L / min
Servo pump Gear pump.
Max flow 20 L / min
Control valve
Combined four- and five-piece control valve with auxiliary section as standard
complete set. If necessary, the flow of twin pumps is fed to the boom, bucket and its handle to increase
speed and performance.
Bypass Valve Parameters
Boom / Stick / Bucket 343 bar
Automatic boost 373 bar
Swivel circuit 289 bar
Motion contour 343 bar
Control control 40 bar
A separate damping valve in the servo system provides softer operation for the booms and sticks, as well as
quick warm-up of the servo system.
Hydraulic cylinders
Bidirectional with screwed end caps and hardened steel bearing bushings. Hydraulic cylinders
booms, sticks and bucket are standardly equipped with damping.
Safety valves are optionally available to protect against bursting of the hoses on the boom and stick cylinders.
Filtration
Compliance with the highest filtration standards ensures a long oil and element life.
hydraulic system.
In a tank of 150 microns, the mesh filter.
The return line of the main circuit is 10 microns, a fibrous element.
1.5 micron bypass line, paper element.
Control line 10 microns, paper element.
The reverse line of the contour of the hydraulic hammer is 10 microns, an element with a reinforced microstructure.
Cooling
Cooling is provided by a purge cooling system with a return line, which is part of a one-way
cooling systems, and water cooling of the engine.
