1. Important Information
The present Installation Manual contains important information for the
correct use of 2 Speed Hydraulic 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:
XT66HD, XT70HD: Hydraulic Winch Vertical. These models are
equipped with a vertical drive hydraulic motor directly connected to
the winch through the disengagement box.
Hydraulic winches retain two speeds both in manual use (inverting the
direction of rotation of the handle) and in hydraulic 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 hydraulic winches the speeds are higher than in manual use even if,
at maximum load, a speed reduction up to 30% must be considered.
Speed
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.
Use
Winches are fitted with hydraulic motors as described in the table at
p.6. The winch speed is proportional to the flow and the winch load is
proportional to the pressure.
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.
