*** at 110 bar at 30 l/min
NOTE
The ratio of the line load - pressure is evaluated at nominal flow rate.
The performance is evaluated measuring the pressure and flow on the motor ports.
The performance data are based on oil with a viscosity of 35mm

/s [165 SUS] and
temperature of 50°C [120°F].

Maximum working load
WARNING!
The maximum working load (MWL) for the 70.3 ST Radial Winch is 2700 Kg (5952 lb)
Subjecting the winch to loads above the maximum working load can cause the winch to fail or
pull off the deck suddenly and unexpectedly during high loads causing severe injury or death.
