Stringing Machine Tools
Stringing machine tools are specialized hydraulic machines used primarily for overhead transmission line construction and maintenance, designed to pull and tension conductors, earth wires, OPGW, and ADSS optical fiber cables safely and efficiently.
-
: These are the core components, providing controlled, infinitely variable tension and pulling forces. For example, models like the SA-YZ30A and SA-YZ40A offer maximum tension forces of 30 kN and 40 kN respectively, with continuous tension slightly lower, and pulling speeds up to 5 km/h.
-
: Ensures smooth and precise tension control in both pulling and pullback directions, with presettable maximum tension and pullback forces displayed on tension gauges for operator monitoring.
-
: Spring-applied hydraulic released brakes automatically engage in case of hydraulic failure to prevent conductor damage and ensure line safety.
-
: Hydraulic oil cooling systems maintain optimal operating temperatures during prolonged use.
-
: Large diameter bull wheels (e.g., 1200 mm or 1500 mm) lined with wear-proof MC nylon segments reduce conductor wear and facilitate smooth stringing.
-
: Machines are often trailer-mounted with rigid axles, allowing towing speeds up to 15 km/h for easy transport on site.
-
: Equipped with reliable diesel engines (e.g., Cummins water-cooled engines with power ranging from 11 kW to 51 kW), combined with high-quality hydraulic pumps and valves from reputable manufacturers such as Rexroth and WIKA.
-
: Some models (e.g., SA-YZ 2X35 and SA-YZ 2X40B) are designed to string two bundled conductors simultaneously, featuring dual hydraulic power outlets to operate two reel stands independently.
