HYDRAULIC SYSTEM
System Type: Open system with filtered return line
Relief Valve:
IMPORTANT
- Set at winch operating pressure
Pump: With a maximum oil supply of 60 l/min at top motor rpm. The
pump must be capable of delivering a pressure of 170 bar.
Reservoir: Must be fitted with an oil filter device comprising strainer
and air filter and a dip stick. The capacity of the tank should be at
least 60 litres (16 U.S. gal). Note: Do not fill the tank to the top, since
there must be space for expansion in the tank. Suitable hydraulic oil
is Castrol CRML or equivalent (150 LHM 32 - 68). Typical viscosity
rating of 150 - 175 cSt at 100°c.
Hoses: Should have the minimum following dimensions:
Pump inlet line: 32 - 38mm (1 1/4” - 1 1/2”)
Nominal Bore (N.B.)
(reservoir to pump)
Return line: 25mm (1”) N.B.
(control valve to reservoir)
Pressure hoses: 13mm (1/2”) N.B.
(control valve to load control valve)
Pressure and flow loss is increased as hose length increases and/or
bore size decreases. Pressure and return lines in excess of 3.5 meters
should be compensated with an increase in nominal bore size.
Control Valve 4 - way, 3 - position with spring centred, open centre
(ports A & B open when in centre position) and built in relief valve.
The relief valve must be set to the winch operating pressure. The
valve should be mounted as close to the winch as possible
Load Control Valve: A single overcentre valve is fitted to the winch
to give smoothly controlled winch out when under load and to
provide full dynamic braking.
Oil Suction Strainer Rating: Approximately 250 microns
Return Line Filter Rating:
10 - 40 microns
INSTALLATION
As a general rule:
Bigger Nominal Bore Hose = Better Winch Performance
In all installation work on a hydraulic system, cleanliness and
accuracy are essential so that the hydraulic system functions
properly.
All winch systems must be protected by an efficient Emergency
Stop system, hydraulic winches should be fitted with a highly
visible engine kill system to stop the vehicle engine driving the
hydraulic system.
MOUNTING
The diagrams on page 6 show the mounting dimensions for the
Superwinch H8 and H10P.
The side and feet mounting hole positions are designed to allow the
winch to be interchangeable with the most popular 8000 - 10000 lbs
units currently available. The diagram below shows the H8P or H10P
mounted on a Superwinch flatbed mounting kit (Part No. 5625),
shown with Roller Fairlead. If a Superwinch mounting plate is not
used, the surface must be flat within 0.5 mm and sufficiently stiff to
prevent flexing. A minimum of 6.0 mm thick steel plate should be
used. The thicker the plate, the better the alignment between motor
mounting, drum and gearbox housing.
It is important that the winch is mounted securely so that the motor
mounting, drum and gearbox housing are accurately aligned. Be sure
the winch will not move under load, otherwise you may cause
misalignment in the winch, causing the drum to bind up.
The tie bars supplied with the winch must remain attached when the
winch is foot mounted. Angle mounting is possible and
recommended for maximum flexibility in mounting. These mounts
allow the winch to be low-mounted. See the diagram below.
Mounting / Fixing hole details:
M10 thread, depth of full thread: 20mm.
Please ensure depth of thread engagement: 15mm.
