NTW trip-wire switches, standard range.

Lanyard rope / trip-wire• Developed to meet AS/NZS conveyor safety standard AS 1755-2000 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 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 high-pressure 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™:

55.1.53P

55.1.53RLR


Red PVC covered galvanised trip-wire Wire rope 7 mm dia. (4 mm wire coated in 3 mm RED UV resistant PVC)

Tripwire note: Standard role 200 metres. Cut lengths cannot be returned.

55.1.53P

LCP fibre lanyard rope NHP/Tufflex™ RED fibre lanyard rope 7 mm dia. (105 m roll)

55.1.53RLR

NHP/Tufflex™ RED fibre lanyard rope 7 mm dia. per metre (840 m roll) 55.1.53RLR-pm

Ordering details:

• 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

Single-sided operationTripwire/lanyard connected to one side of the trip-wire switch (either left or right) and terminated with a return compensation (tension) spring.

Double-sided operationTripwire/lanyard connected to both left and right hand sides of the trip-wire switch. Both left and right hand lanyards are terminated with a return compensation (tension) spring.

Multiple double-sided installationsFor longer conveyor runs, must be installed as shown below:

• Individual maximum lengths of lanyard (shown as ‘X’ in the diagrams above) in a horizontal plane must not exceed:

– 100 m when using NHP/Tufflex™ Lanyard rope (Cat. no. 55.1.53RLR) – 60 m when using NHP red PVC coated galvanised steel cable (Cat. no. 55.1.53P)

• NHP recommends the use of NHP/Tufflex™ as the lanyard when the conveyor system is operating over a 5 degree incline from the horizontal.

• 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.

Heavy duty pull-wire switches cont

Type NTW cont

NTW trip-wire switches, standard range.

1. Firmly mount the trip-wire switch using the four mounting points on the trip-wire unit:

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 trip-wire 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. If necessary, re-adjust the turnbuckle until the end of the shaft is in-line with the end of the setting gauge. If desired, the setting gauge can now be removed.

11. The trip-wire switch set-up is now complete.
