Cleaning and greasing of steel sliding bearings :

Following equipments are required for greasing of steel sliding bearings:

1. Jacks (50 ton capacity) - 2 nos.

2. Hard wooden packing below and above jack

3. Grease graphite Grade 3 conforming to IS:508

4. Kerosene or released black oil for cleaning

5. 6 mm thick steel scrapers

6. Mortar pan

7. Cotton waste

Greasing of sliding bearings can be undertaken under traffic with issue of caution order and line protection for temporary works as per provision of IRPWM.

Lifting of girder should be restricted to 8 to 10 mm only, ensuring that the bearing strip does not get lifted over locking strip and guide strip to avoid creep of girder in logitudinal and lateral direction. For lifting, it is not necessary to break the track. Only loosening of fish bolts and dog spikes over a small length on both sides of the pier is sufficient. Only one end of the girder should be lifted at a time and steel scraper inserted between bearing strip and base plate to remove old grease dust and dirt. The contact surface is cleaned with oil and grease applied. Girder is then lowered back over the base plate. Time required for all these activities is approximately 15 to 20 minutes.
