1. Important Information
The present Installation Manual contains important information for the
correct use of 2 Speed Electrical XT winches and you are therefore
advised to read it carefully before using the product.
The present manual gives technical information for the installation and
the maintenance of the following XT winch models:
XT66EH, XT70EH - Electric Horizontal Drive: These models are
equipped with an electric horizontal motor and a speed reducer with a
worm screw.
XT66EV, XT70EV - Electric Vertical Drive:These models are equipped
with an electric vertical motor and a high efficiency hypocycloid speed
reducer.
Electric winches retain two speeds both in manual use (inverting the
direction of rotation of the handle) and in electric use (pressing one of
the two control buttons).
It is of fundamental importance to be able to choose the most suitable
speed for the manoeuvre that you want to perform; this allows fast
recovery of the first part of the manoeuvre and more careful regulation
in the final stage.
In electric winches the speeds are higher than in manual use even if,
at maximum load, a speed reduction up to 30% must be considered.
Speed
Motors with a power of 1500 Watt are used to drive the winches,
depending on the size of the model. Considering a mean reduction
gear efficiency of 70%, this gives powers of 1050 Watt at winch intake.
It is interesting to compare these figures with the power value in manual
use, which is conventionally considered to be 400 Watt.
Power
Antal powered winches come supplied with a chrome - plated bronze
drum. Black anodized aluminium drums are available on request, in
this case the aluminium drum is “reinforced” applying a special toothed
crowngear of high resistance alloy or chromed bronze.
Winch Drum
Simply insert the handle to disconnect the speed reducer-motor unit.
For Greater Safety: accidental starting of the motor does not affect
the winch, avoiding dangerous turning of the handle.
For Greater Efficiency: the speed reducer-motor unit does not turn in
manual use, avoiding needless friction.
