2.3 Winches
The endless winches on this machine does
not collect the steel cable, but moves it
through the winch at the desired speed.
Therefore, the lifting height is
determined by the cable length.
Use only Blastrac approved steel cables.
The steel cables can be ordered in every
desired length. See the Service manual
for the correct part number.
The endless winches are provided with an
electro-magnetically released spring brake,
which closes automatically when the
button for UP/DOWN travel is released
and in the case of a power failure.
The winches have an overload detection device in
accordance with EN 1808 built into the winch.
Pressing the emergency stop button shuts down the
entire control unit in the event of an
emergency. The button can be released again by
rotating it in the direction of the arrow and
pulling it outwards.
In an emergency, for example in the case of fire or a
power failure, the load can be lowered or lifted
manually.
