Accessories and spare parts: Lanyard rope / trip-wire P Developed to meet AS/NZS conveyor safety standard AS these ropes are specially tested to work in conjunction with the NHP/Austrol NTW 55.4 series trip wire switches Two types are available, i.e. PVC covered galvanised trip-wire, and the new NHP/Tufflex fibre lanyard rope NHP/Tufflex fibre lanyard rope RLR A unique combination of properties differentiates NHP/Tufflex fibre from other high-performance fibres and makes it the material of choice to meet performance requirements in demanding applications. The remarkable mechanical performance of NHP/Tufflex combined with the other unique properties, permit it to be used for a wide variety of purposes. NHP/Tufflex unique fibres are used in aerospace, ocean exploration and development, electronic support structures, safety materials, industrial applications, composites, protective apparel and highpressure inflatables. NHP/Tufflex is a high-performance multi-filament yarn spun from liquid crystal polymer (LCP). It is the only commercially available melt-spun LCP fibre in the world exhibiting low weight and exceptional strength and rigidity. It is five times stronger than steel and ten times stronger than aluminium. These unique properties characterise NHP/Tufflex : High strength and modulus Low coefficient of thermal expansion (CTE) Excellent creep resistance High dielectric strength High abrasion resistance Outstanding cut resistance Excellent flex/fold characteristics Minimal moisture absorption Excellent property retention at high/ low temperatures Outstanding vibration damping characteristics Excellent chemical resistance High impact resistance Description Red PVC covered galvanised trip-wire Wire rope 7 mm dia.

NHP strongly recommends that pulleys are not used with the galvanised steel cable i.e to curve the tripwire/lanyard around conveyor bends, and that pulleys only be used with NHP/Tufflex as the lanyard.

21 Heavy duty pull-wire switches cont Type NTW cont NTW trip-wire switches, standard range. Method of installation for single and double-sided operation: 1. Firmly mount the trip-wire switch using the four mounting points on the trip-wire unit: open view Schematic showing operating lever centred in the middle of the operating cam. A. For double sided installation A maximum of 100 m from one end of the conveyor when using NHP/Tufflex, or A maximum of 60 m from one end of the conveyor when using NHP PVC coated galvanised cable as the lanyard. B. For single sided installation Mount the trip-wire switch at one end of the conveyor, ensuring that the maximum length of the tripwire/lanyard does not exceed: 100 m when using NHP/Tufflex or, 60 m when using NHP PVC coated galvanised wire as the lanyard. Note: If either of the above distances are to be exceeded, then a double-sided installation must be used. 2. Fit the return compensation (tension) spring: C. When using NHP/Tufflex as the lanyard: A maximum of 100 m from each side of the trip-wire switch for double-sided installations, or a maximum of 100 m from one side of the trip-wire switch for single-sided installations. D. When using NHP PVC coated galvanised steel wire as the lanyard: A maximum of 60 m from each side of the trip-wire switch for double-sided installations, or a maximum of 60 m from one side of the trip-wire switch for single-sided installations. 3. Position lanyard wire supports at a maximum spacing of 4 m between the return compensation spring and the trip-wire switches. Smaller spacings will ensure higher performance of the tripwire system. 4. Run the lanyard between the trip-wire switch and the return compensation springs. 5. Terminate the lanyard at the return compensation spring ends using thimbles and clamps. If using the PVC coated galvanised cable, remove outer PVC sheathing before clamping. Secure to the return compensation spring using D shackle if necessary. 6. Unwind both ends of the turnbuckle/s to give maximum extension and hook one end to the shaft of the trip-wire switch using the provided D shackle. 7. Terminate the other end of the lanyard to the turnbuckle/s using thimbles and clamps. If using the PVC coated galvanised cable, remove outer PVC sheathing before clamping. Before tightening clamp to lanyard, pull through all slack until taught, then tighten clamp. 8. Attach the external setting gauge/s using the screws provided, into the threaded holes, either above or below the external trip-wire switch shafts. 9. Adjust the turnbuckle/s until the end of the shaft is in-line with the end of the setting gauge. 10. Pull the lanyard numerous times to bed-in the cable and remove any deadband from the system.
