6.4 Actual sleeper length adjustment SL450
The sleeper layer SL450 is designed for a variation in length on sleepers. The minimum
sleeper length is 2490 mm and the maximum length is 2800 mm as standard (option
2220 mm - 2530 mm).
The adjustment can be done on both sides of the sleeper layer. The figures below
shows where the adjustment is done.
Description:
1. Measure the length of the current sleeper.
2. Loosen the bolts using two 21 mm spanners.
3. Measure the distance between the grapple arms with the hydraulic cylinder
extracted.
4.
Slide the fixed grapple arm to desired position (Fig. 8).
5.
The grapple arm with the hydraulic cylinder needs space to grab the sleeper,
therefore the distance between the grapple arms should be minimum 20 mm
shorter than the length of the sleeper.
6. Tighten the bolts.
