Definitions
- the invention concerns a hydraulic rotate system, in which a shunt is laid across the supply gate of the hydraulic motor.
- the invented system Because of its characterization, which consists in in ⁇ creasing ability of braking on on increasing speed, the invented system also prevents the situations, where the crane starts to rotate uncontrolled, when about the half of the working area of the crane is laying under cover from the wind.
- Fig. 1 shows a schematic outline of the invention in unactivated situation.
- Fig. 1 shows a schematic outline, as per the invention, seen in unactivated circuit loose situation, where the hydraulic motor A can circulate oil through a two-ways valve C and a blend B, when the crane is to be able to place itself in the direction of the wind.
- a steering valve D is activated to start the rotate movement, according to, if all the oil are wan- " ted to the motor A on powerful start or more mild start with pressure- and flow reduction through blend B, the valve C respectivelycan be activated or stay in the
