Installation and Maintenance Manual - Mod.D
Maximum working load
WARNING!
The maximum working load (MWL) for the UniPower Radial Winch is 900 Kg (1984 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.
Outline
Installation
The winch must be installed on a flat area of the deck, reinforced if necessary to bear a load equal
to at least twice the maximum working load of the winch. It is the installer's responsibility to carry
out all structural tests needed to ensure that the deck can bear the load. Harken
®
does not supply
the screws needed to install the winch since these may vary depending on the deck on which it
is to be installed. It is the installer's responsibility to choose the correct screws taking account of
the loads they will have to bear. Harken
®
assumes no responsibility for incorrect installation of its
winches or for an incorrect choice of mounting screws.
DANGER!
Incorrect installation of the winch may cause severe injury or
death. Consult the yard that built the boat in the case of doubt
over the correct positioning of the winch.
WARNING!
Failure to use the correct number and type of mounting fasteners
or failure to ensure the correct deck strength can result in the
winch pulling off the deck suddenly and unexpectedly during
high loads causing severe injury or death.
WARNING!
Verify the entry angle of the sheet. This must be 8° with tolerance
of ±2°, to avoid sheet overrides and damaging the winch or
making the winch inoperable leading to loss of control of the boat
which can lead to severe injury or death.
