Angle Chart
The maximum weight the OzWinch Signature Series II electric winch can haul
depends on the angle of the hauling surface e.g. driveway or slipway.
To determine the safe weight for the angle of the hauling surface, calculate the total
weight of the hauling object (e.g. boat and trailer or other vehicle). Use the angle
chart below in Table 2 to assess the maximum weight to safely haul the object
against the angle of the hauling surface.

All figures given in the Angle Chart are based on a hard surface such as concrete or
steel tracks with bearing steel wheels or rubber tyres.
The total hauling object maximum weight determines the limit of the angle of the
ramp.
CAUTION
Never exceed the safe maximum weight and angle when operating the
electric winch.
