Hydraulic Climbing Jacks

1

Step 1 The steel spreader beam passed under the bogie to a similar arrangement on the opposite side of the train.

2

Step 2 The ram was then extended, lifting the train by over 100mm.

3

Step 3 Wooden blocks and steel spacers were then placed underneath the jack.

4

Step 4 The ram was then retracted to bring the train to rest on the spacers and wooden blocks.

5

Step 5 Three more wooden blocks were then slid under the jack.

6

Step 6 The ram was then extended again, and the spacers removed.

7

Step 7 This time two outer wooden blocks and spacers were placed at right angles to the previous ones to form a stable tower.

8

Step 8 The ram was then retracted again and three more wooden blocks slid into place.

From here the process was repeated until at the required height of 1.3 metres.
