DIFFERENT FUNCTIONS OF OUTER HYDRAULIC CIRCUIT CONTROL LEVERS
There are four positions of the lever (a):
N -
Neutral position. Quick coupler drives (1) and (2) are closed and oil in the hydraulic appliance connected is blocked. Lever
(a) is locked in this position.
1 -
Pressure in quick coupler (1). Quick coupler (2) is connected with the drain. Lever (a) is locked in this position. In case
pressure exceeds 16.5 MPa when connected to quick coupler (1), lever (a) automatically returns to (N) position – „kick-out“
function.
2 -
Pressure in quick coupler (2). Quick coupler (1) is connected with the drain. Lever (a) is locked in this position. In case
pressure exceeds 16.5 MPa when connected to quick coupler (2), lever (a) automatically returns to (N) position – „kick-out“
function.
P -
Floating position. Both quick couplers (1) and (2) are connected with the drain and oil is free to flow in both directions.
Lever (a) is locked in this position.
