3.6 POSITIONING AND ANCHORING
Positioning and anchoring of the machine have to be carried out only by trained personnel, verifying if
the ground grants the foreseen stability, support and anchoring.
The machine has to be placed in a distance from the first pylon or trestle for the rope passage (or
conductor) included between 2 and 4 times the height h of the pylon itself (see diagram here below).
It is possible to use the machine at a distance from the pole included between 1 and 2 times the height
of the pole itself. In this case, the anchorage described thereafter must be over dimensioned of 125%
compared to the reported data and some moorings must be provided on the front side of the machine.
PROHIBITION: when the distance between the machine and the pole is lower than the
height of the pole itself, the machine use is not possible.
Machine anchoring sequence is the following:
a. machine must be aligned as much as possible with the pull direction.
b. position the rear stabiliser (table 1, pos. 10) and then load properly the plough (table 1, pos. 5)
operating on the lever (table 3, pos. 29) (NOTE: during this operation the diesel engine has to be
always started-up).
c. anchor the machine to the ground by means of 2 stakes with min. granted load equal to 130% of
the machine max. pull, connecting the foreseen connections (table 2, pos. 3) with the anchoring
stakes and respecting the described scheme and angles (table 2).
d. recover the clearance on the anchoring stakes without tensioning them.
e. test the machine pull (see use instructions on the following chapter) to allow the machine to freely
align as regards as the pull itself.
f. tension the anchoring stakes in a uniform way.
g. block the machine brakes acting on the special hand-wheel (table 1, pos. 9).
ATTENTION: the non-respect of the foreseen anchoring operations may cause dangerous
situations during machine use.
Around the machine must be a free space of at least 2-m to make easier the operations of use,
adjustment, maintenance, etc.
Be sure that around the radiator (endothermic engine, hydraulic oil) cooling air can freely circulate.
Otherwise overheating situations with damage for the installed components may happen.
DANGER: machine has not a proper grounding device; for the system machine-rope-
conductor in the job site must foreseen a grounding device on the towing rope or on the
conductors.
