The wheels are made of aluminium alloy mounted on ball bearings; the lateral ones have the groove lined by neoprene ring; the central one has the groove made up of wear-proof interchangeable nylon sectors. The frame is made of galvanised steel. The pulleys are supplied with fixed connection Fibre optical cables head boards mod. RFF Specifically designed to connect the pulling rope with a fibre optical cable. They are composed of several jointed rods and two arched rods (to facilitate the passage on the pulley), and two drawback counterweights (to avoid cable twisting) Two or three bundled conductors head boards mod. RB/RF Specifically designed to connect the pulling rope, max 24 mm diameter, with 2 or 3 bundled conductors. The equipment includes the necessary rope lengths and swivel joints; quantity and models are indicated in the following tables Four bundled conductors head boards mod. RB/RF Specifically designed to connect the pulling rope, max 28 mm diameter, with 4 bundled conductors. The equipment includes the necessary rope lengths and swivel joints; quantity and models are indicated in the following tables Fixed joints mod. GFT The fixed joints are specifically designed to connect pilot rope lengths or pulling rope lengths and to pass over the puller or puller-tensioner bull wheels. The special profile minimises the overload on the rope spliced eyes during this passage. They are made of highly tensile galvanised steel Swivel joints mod. GGT The swivel joints are suitable to connect the pulling rope to the mesh sock joint mounted on the conductor; they are mounted on thrust bearings and they are designed to avoid torsion strain accumulation.They are made of highly tensile galvanised steel; the special design can bear the high radial loads, which occur during the passage over the pulleys Temporary mesh sock joints mod. GCT The head-type temporary mesh sock joints are specifically designed to temporarily connect the aluminium, steel or copper conductor to the pulling rope. They consist of variable pitch steel wires, which effectively distribute the gripping effect on the conductor. The double head-type temporary mesh sock joints are specifically designed to temporarily connect the aluminium, steel or copper conductors. They consist of variable pitch steel wires, which effectively distribute the gripping effect on the conductor. Self gripping clamps mod. MOT The self-gripping clamps can be used whenever a conductor, a cable or a rope made of aluminium, aluminium/steel, copper or steel, even if insulated, has to be stretched. The body is made of high-strength hot forged steel, in order to minimise weight in comparison with the working load. The galvanisation treatment on the surface protects from oxidation. The most important characteristic is the possibility to use the same clamp for working on conductors or ropes of different diameters only by changing the jaws; this feature makes it possible to reduce the operating costs Self gripping clamps Mod. MOR The self-gripping clamps can be used whenever a conductor, a cable or a rope made of aluminium, aluminium/steel, copper or steel, even if insulated, has to be stretched. The body is made of high strength hot forged steel, in order to minimise weight in comparison with the working load. The galvanisation treatment on the surface protects from oxidation. The most important characteristic is the possibility to use the same clamp for working on conductors or ropes of different diameters only by changing the jaws; this feature makes it possible to reduce operating costs Radial locking clamps mod. MOS The radial locking clamps can be used whenever a conductor or a rope made of aluminium, aluminium/steel, copper or steel has to be stretched. The body is made of high-strength steel. It is made up of a series of hinged elements, which can be locked by nuts. A special hook is provided at one end. The galvanisation treatment on the surface protects from oxidation Hydraulic presses mod. PRT The hydraulic presses, mainly implemented in press forged steel, have the following characteristics: - excellent weight/power ratio - very short pressing cycle (all the presses have a hydraulically-driven piston release) - each power unit or manual hydraulic pump (and hoses) is interchangeable with any hydraulic press Accessories for hydraulic presses PRT Hydraulic power units Manual pump Kit of connecting hoses Dies for conductors Dies for coupling Straightening joint devices Cover joints mod.
