What is the ATD
2.1.Description
ATD is a specific tool to be used only for tree care operations, for lifting or lowering tree
sections
during controlled felling (rigging) or pruning
(eg. removal of large dead or
damaged branches).
ATD consists of a metal frame which acts as a support to a winch, wrapped by a aluminium
cylinder brake, a
mechanical safety blocking system (stopper) and two
straps (for anchoring
and positioning) .
Since the ATD is not the only equipment used during the rigging, it is necessary that all the
other components (
ropes, blocks, pulleys, slings,
straps, connectors, etc) are in good
condition of use, properly sized for the work
to be performed and compatible with each
other.
All operating instructions must be observed, those
indicated in this manual as well as those
provided with each device combined to the ATD .
Caution:
The a
ctivities involving the use of the ATD are inherently dangerous.
Who uses the ATD is responsible for his/her own actions, decisions and safety.
It is mandatory to follow the current safety standards.
Before using the ATD you must:
•
read and understand all operating instructions described in this manual;
•
be
properly trained for controlled felling with the use of aluminium cylinder brakes
and
winches
•
