Hydraulic System Requirements; Emergency Stop; Typical Layout; Performance Charts - RAMSEY WINCH HD-P 177,9 Traduction Des Instructions Originales

Refer to the performance charts below to properly match your hydraulic system to the winch performance. The
charts consist of: (1) Line Pull first layer kN (lb) vs. Working Pressure (PSI). (2) Line Speed, first layer MPM
(FPM) vs. flow LPM (GPM).

HYDRAULIC SYSTEM REQUIREMENTS

1. Motor spool (open center) control valve.

2. Emergency Stop:

A. If winch is controlled by a direct-operated manual valve, that valve serves as the E-stop.
B. If a remote operated control valve is used, a solenoid-operated hydraulic dump valve, normally open to
tank, and an emergency stop switch (to open the dump valve) is required. The E-stop switch is to be
normally closed and have a red, resettable push button actuator with yellow background. The E-stop
switch must be easily accessible to the operator.
3. Relief valve set at 193 bar (2800 psi) which is the rated capacity limiter.
4. Flow rate of 64,3 LPM (17 GPM) maximum. Do not exceed 75,7 LPM (20 GPM) or motor and winch may be
damaged.
5. Hydraulic fluid with a viscosity between 20-43 cSt (100-200 SUS). Maximum operating temperature 85C
(180F). Cleanliness level of ISO 17-14 or better.
