3. KNOWING THE MACHINE
3.1 TYPOLOGY AND USING FIELD
The puller-tensioner mod. PT1250 It is suitable for the traction of 1 conductor with a diameter of max 42
mm and for the recovery of a rope with diameter 16.
The machine is governed by a hydraulic system which allows it to automatically configure itself as
PULLER or as a TENSIONER.
The power transmission to the wheels of adhesion is achieved through a closed hydraulic circuit with
variable displacement pump and a fixed displacement engine, with the possibility to vary continuously the
speed in both directions of rotation.
An hydraulic drive brake allows to automatically lock the wheels of grip when the work stops and in case
of failure in the hydraulic circuit.
The puller-tensioner has a reel winder with hydraulic command with automatic lever winder, rear
stabilizer, front hydraulic control jack and attacks and for the anchorage to the ground; The case comes in
a rigid axle for towing at 30 km/h and of a handbrake hand wheel. The machine can be equipped with
special equipment approved for road transport at max. speed of 80 Km/h.
3.2 PERFORMANCES
Max. pull. 50 kN
Max. pull speed. 1,5 km/h
Max. speed. 5 km/h
Pull at max. speed. 16 kN
Performances are referred to the machine without optional, at sea level and at 20°C.
DANGER
use with ropes or conductors of smaller diameter than the maximum allowed
involves the reduction of the max pull. applicable in relation to the workload
guaranteed minimum of rope or conductor.
