3 RE 65051/08.04 YM-WC Industrial Hydraulics osch Rexroth G 3/12 Function General The YM-WC control block is suitable for use with anchor, warping and mooring winch systems. The combination of the pressure compensator (013) with the directional spool valve (011) and the pilot control (02) makes a precise and load independent control of winches possible. controlled load lowering is achieved via the integrated load lowering valve (012). When the operating lever is moved the holding brake is hydraulically released. The pressure relief valve (015) which is fitted to the load holding side protects the system from overloads. The pilot pressure supply is internal via a pressure reducing valve (023) and is taken from the port. The pilot pressure is only used up to a imum of 16 bar for controlling the directional valve (011). t 16 bar the noal speed at the imum pulling force is acheived. The lever, in the directional control valve (011) adjustment range, is, when released, returned to the centre position by means of springs. referred use of variable displacement motors. further increase in the pilot pressure makes it possible to adjust the motor (6VM) from the imum to the imum stroke and thereby the displacement volume. The drive torque is thereby reduced and the speed increases, the power however remains the same. Version H Hand lever with hydraulic remote control connection dditionally a hydraulic pilot control unit can be fitted via thread holes. proportional remote control (. control pressure 25 bar). Version W Warping system applications With a pilot pressure of 16 bar there is no change to the motor s imum swivel angle (noal pulling force). y increasing the pilot pressure the motor swivel angle reduces and thereby increases the line speed, at approx. 24 bar a value of three times the basic setting (slack rope speed) is achieved. higher speed can be achieved by adjusting the imum swivel angle adjustment screw. Version C nchor / warping system applications The motor is so set that when a pilot pressure of 18 bar at port is applied, the swivel angle for the required noal force is set. y operating the switchover valve (03) with the spring return, the motor is set to the imum swivel angle and a defined anchor brake-out force is achieved. Versions and K Mooring or anchor / mooring winch systems The directional spool valve (011) is not operated during mooring operation. It is in its mid position. The pressurised oil supply is only via the spool (021) of the pilot control (02). The line force is set via the lever deflection and the related motor swivel angle. safety relevant imised mooring speed is guaranteed. Note! The pressures stated in the above text are approximate values. Version E Hand lever with electrical proportional remote control proportional pressure reducing valve (04) which is fitted to the pilot control (02) makes it possible to have an electrical Force-velocity diagram ine velocity ine force ever deflection angle in Control pressure in bar
