d. anchor the machine to the ground using 2 ropes each having a load of use guaranteed minimum of 700
kN linking the connections provided (tab. 2 pos.8 and tav.3 pos.10), in the rear of the machine, with
anchoring pegs. The attacks used to be an anchor shackle with a breaking load of 17 tons and the
safety factor of 5. It is necessary that the ropes make an angle with the direction of pull as shown on the
table 9, to allow the machine to withstand even any transverse loads.
IMPORTANT
before starting stringing operations, we suggest to test the pull, reaching the
max. value expected for the operations, in order to check the carried out
anchoring and the machine settling. It is better to have the rear anchoring
slightly released so that the machine can freely settle.
f. put the anchoring ropes under tension using the suitable turnbuckles (if necessary, anchor the
machine also in the front).
g. block the machine brakes acting on the handle brake wheel.
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 radiators (endothermic motor, 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 foresee a grounding device on the towing rope
or on the conductors.
