LASE-ALIGN KIT MK II

TRACK LASER ALIGNMENT GAUGE

Switch Tip Alignment
Made simple and accurate without the need for tape measurements and calculation.

Twin laser heads mounted in a solid metal frame ensure total accuracy and reliability. The integral magnets will hold the Lase-Align in place against the field stock rail face to ensure accurate placement.

Place Lase-Align onto rail head aligning the relevant datum line (90mm or 255mm) with bearer one (toe) stock rail bolt. Project the laser across to the small target board and measure the alignment off set.

The laser can also be used for setting datum points by projecting the centre line reference.

CORRECT POSITIONING OF DRILL HOLES
Fix Lase-Align unit over first hole centre line. Turn on laser and the red dot will indicate exactly where on the opposite rail hole should be drilled. Mark rail accordingly.

TRACK SLEWING
Note: The Slewing Target 0111/120123 is not supplied as part of the kit and should be ordered seperately if required.

The Target is intended to align straight rail into switches and crossings. This process should be used once a site survey has identified the alignment defect limits.

Place the Target at the furthest end of the section under test with the Lase-Align at the start point. The red dot should be centred on the line on the target.

Bringing the Target towards the Lase-Align will show misalignment of the track if the dot deviates away from the target line. The track should be re-aligned with the dot on the line.

ADJUSTMENT OF SWITCHES
Alignment checked in seconds using small Target Board (039/127031)

CROSSING NOSE ALIGNMENT
Check crossing nose position in relation to the rest of the junction with the use of the laser and small Target Board. This should be done in accordance with NR/L2/TRK/2049.

RAIL DIP MEASUREMENT
The units adjustable second laser can be set to the centre of the large Target Board (039/127032).

Once the two datum points have been established the laser provides a clear, accurate and easily read alignment tool. The use of the laser means this can be done at night without the need for heavy lighting.

By moving the target board to the intermediate points this will give an accurate measure of dip for the stone blowing or shovel packing.

  USER INSTRUCTIONS: LASE-ALIGN

Introduction
The Lase-Align has been designed in conjunction with and to Network Rail standards (NR/TRK2049/mod3) and in association with Mr Neil Denton the former Network Rail National S&C Specialist. The gauge is designed for use on the Rail Infrastructure to accurately measure Switch Tip Alignment and Adjustment, Crossing and Check Rail Alignment. Track Slewing and Rail Dip Measurement.

Switch Tip Alignment and Adjustment
Before starting the operator should ascertain Rail Size and Switch Type (left hand turnout / right hand turnout / semi flex / contra flex or route handed).

The operator whould also ascertain which company manufactured the Switch as they may have different set ups as per Manufacturing and Network Rail Standards. Then ascertain the lead length by measuring from the switch tip to crossing nose. (see diagram below)

Once lead length is ascertained place the Lase-Align into the Railhead of the Main Line Stock Rail and align the relevant datum line (90mm = 113Ib and Cen56 Rails) or (255mm = RT/NR60 Rail) with the centre of the first bolt hole. The integral magnets will hold the Lase-Align in place against the field stock rail face, then place the small target board on the opposing rail with the correct relevant datum line, allowing for the 90mm offset. Switch on the Lase-Align and adjust the position until the red laser dot shows on the Target Board indicating the point exactly opposite, then measure and record all measurements as per Network Rail Standard.

Other Network Rail Standards to work to

When adjusting squareness of stock rails repeat process above, place the Lase-Align onto the Railhead of the Main Line Stock Rail and align the relevant datum line with the centre of the first bolt hole. Place the small Target Board on the opposing rail with the correct relevant datum line again allowing for the 90mm offset. Switch on the Lase-Align and adjust position until the red laser dot shows on the Target Board indicating the point exactly opposite then measure and record all measurements as per Network Rail Standards.

Crossing Noise Alignment
Take the nose to nose measurement from the switch in accordance with NR/TRK/2049/mod3/Page 12 C.1.6. and mark the rail head. Place Lase-Align on the rail head with the laser directly over the mark on the main line and position the Target Board in the flange way of the adjacent crossing with the centre mark directly in line behind the crossing nose. Switch on the Lase-Align. The laser dot should be on the centre line of the Target Board. Measure and record any variations as per Network Rail Standards.

Die Measurement
Select the two datum points on track where the dip is suspected. Place Lase-Align on the head of the rail at the first high point making sure it is level using the spirit level fitted. Place Target Board on the head of the rail at the end high point and using the spirit level fitted ensure target is level. Switch on Lase-Align using the adjustable laser, adjust the dot down to the bottom line on the Target Board. Move the Target Board periodically towards the Laser Measure and record all low points and adjust to comply with Network Rail Standards.
(TRK/001/mod11)

Track Slewing
Like dip measurement select the two datum points on the track. Place the Lase-Align on the head of the rail at the start of the suspect fault. Then position the Slewing Target at datum point two and ensure the target is level by using the built in spirit level. Switch on the adjustable laser and align laser dot with the line on the Slewing Target Board, then periodically move the Target towards the Lase-Align, making sure the Target Board is always level. Measure and record any variations to comply with Network Rail Standards.
(TRK/001/mod11)

Lase-Align Calibration
To test the Lase-Align before use. Securely fox a 550mm piece of new rail to a fixed level bench parallel to and 1435mm away from a vertical face such as a wall. Make a vertical permanent mark or cut on the side of the rail head facing the wall at its centre. Place new Lase-Align on the rail aligning the notch under the side laser with the mark on the rail head. Switch on laser pointing towards the wall. Fix the Self Adhesive Target (supplied in the kit) to the wall with the red dot exactly in the centre of the target. Once installed the Lase-Align can be checked before use to ensure the fixed laser is within the required field of accuracy.

It is recommended the unit be inspected and calibrated on a regular basis depending on usage and at a minimum period of 12 months.
