Precision Tensioning for Power LinesWith a dual independent drum design, the TY4x50 Tensioner enables fine-tuned tension control, crucial for laying and maintaining high-voltage conductors. Its automatic hydraulic regulation maintains consistent force, reducing line sag or damage during installation. The digital display offers real-time readings, giving operators full command of line tension and speed.
High Durability and Operator SafetyCrafted from high-strength steel and anti-corrosive alloy, this tensioner withstands demanding environments. Operator safety is prioritized through hydraulic fail-safe multi-disc brakes and an overload/emergency shut-off system. The cabins shock-absorbing seat ensures comfort during prolonged use, even in challenging weather or extended operations.
Easy Mobility and Efficient OperationThe TY4x50 comes trailer-mounted for effortless transportation between job sites. It accommodates demanding projects with a maximum flow rate of 250 L/min and an operational pressure up to 25 MPa. Hydraulic quick connectors and included accessories, such as drum clamps and hose kits, streamline setup and daily usage, saving valuable project time.
FAQs of TY4x50 Max Tension 4x50(2x100)KN Hydraulic Tensioner For power transmission line Machine:
Q: How is the TY4x50 hydraulic tensioner commonly used in power transmission projects?
A: The TY4x50 is primarily used for tensioning conductors during the installation and maintenance of power transmission lines. It ensures consistent, controlled tension, which is essential for preventing conductor sag and maintaining system reliability.
Q: What are the benefits of the hydraulic automatic tension regulation system?
A: The automatic hydraulic system maintains precise, stepless tension control without manual intervention. This feature minimizes conductor stress, reduces risk of snapback, and enhances installation efficiency by optimizing tension at all times.
Q: When should I use the dual groove (4x50 or 2x100 kN) configuration?
A: The dual groove configuration allows for flexible operation, supporting either four conductors each at 50 kN or two conductors at 100 kN. Use the appropriate setup depending on the cable type, required tension, and project scope.
Q: Where is the tensioner best operated, and what is its environmental tolerance?
A: This machine performs efficiently in a variety of environments thanks to its temperature range of -20C to +50C and corrosion-resistant construction. Its trailer-mounted mobility enables use on remote or uneven terrain typical of transmission line projects.
Q: How does the hydraulic fail-safe braking system contribute to safety?
A: The hydraulic fail-safe multi-disc brake automatically engages in case of loss of hydraulic pressure or emergency stop, ensuring the conductors remain securely held and minimizing potential hazards to personnel and equipment.
Q: What is the setup process for operating the TY4x50 tensioner?
A: Setting up involves positioning the trailer-mounted tensioner, attaching the appropriate drum clamps and wire ropes (up to 40 mm in diameter), connecting the hydraulic hoses, and powering up the diesel engine. The control system and digital displays make calibration and monitoring straightforward.
Q: What accessories and support materials are included with the TY4x50 tensioner?
A: Each unit comes with standard drum clamps, hydraulic hose kits, a detailed operation manual, and quick-connect hydraulic fittings. These accessories facilitate installation, operation, and routine maintenance.
