13. R On wire rope installation care must be taken that the wire rope is wrapped completely around the cable anchor and properly pulled into the cable anchor slot in the cable drum The cable drum requires 5 wraps of wire rope for safety The winch operation is controlled by a single control valve lever which has a forward a reverse and a neutral position Speed control in either direction is obtained by modulation of the control valve lever Maximum line speed in either direction is obtained when the control valve lever is moved as far as it can go The disc brake of the winch will come on automatically when the winch control lever is returned to neutral Always warm up equipment prior to operating winch particularly in low ambient temperature Circulate hydraulic oil through the winch control valve for several minutes to warm the hydraulic systems To prime the winch with warm oil operate the winch at slow speed forward and reverse several times To ensure proper winch installation and function raise and lower a full test load to a safe height before using winch for regular operation at the start of each shift If after a new installation the winch does not function properly refer to the TROUBLESHOOTING section of this manual PAGE 10 262 REV 051117 TROUBLE SHOOTING GENERAL In most cases when the hydraulic winch does not perform satisfactorily the cause for malfunction is found somewhere in
14. RAULIC CIRCUIT STACKED CONTROL VALVE Refer to above hydraulic circuit when the winch control valve is one of several stacked control valves and has a cylinder spool winch ports blocked in neutral position In this configuration the safety valve must be replaced with a drain line plumbed directly to the reservoir The drain line cannot be connected to a common return line IMPORTANT proper function of the winch any circuit the return line back pressure measured at the motor return port and the brake housing pressure measured at the safety valve must not exceed pressures per SPECIFICATIONS 262 REV 030408 PAGE 7 RECOMMENDATIONS HYDRAULIC FLUID The hydraulic fluid selected for use with PULLMASTER planetary winches should be a high grade petroleum based fluid with rust oxidation and wear resistance Fluid cleanliness and operating viscosity are critical to winch reliability efficiency and service life For optimum performance the recommended viscosity range at operating temperature is 81 167 SUS 16 36 CS For extreme operating conditions of short duration the maximum viscosity range of 58 4635 SUS 10 1000 CS should not be exceeded The winch recommended hydraulic fluid temperature operating range is 80 150F 27 66C For extreme operating conditions of short duration the maximum temperature range of 5 180F 21 82C should not be exceeded LUBRICATION The winch gear train re
15. TION HOISTING In forward rotation the output torque and RPM of the hydraulic motor are transmitted to the sungear of the primary planet reduction The output of the primary reduction is transferred to the final sungear which is splined to the primary planet hub The final planet assembly does not rotate so the rotation is transmitted to the cable drum by the final drive planet gears In forward rotation or when a load is lifted an over running clutch which connects the motor drive shaft to the automatic brake assembly permits free rotation of the sungear without effecting the brake When the winch rotation is stopped the load on the cable drum causes the over running clutch to lock and the maximum load is held safely by the disc brake FUNCTION IN REVERSE ROTATION LOWERING In reverse rotation or when the winch is pressurized for lowering a load hydraulic pressure from the reverse side of the hydraulic motor is channelled to the brake piston causing the brake piston to release the multi disc brake against a number of brake springs The over running clutch connecting the motor drive shaft to the brake assembly locks causing the brake discs to rotate between divider plates which are engaged into the brake housing If the load on the cable drum tends to effect the lowering speed the resulting pressure drop in the brake piston causes friction between the brake discs and the divider plates In this way a completely smooth paying out s
