Measurement conditions
(1) Hydraulic oil temperature: 50 ± 5°C, Machine front at travel position
2.
How to measure the travel block performance
(1) Travel the machine over a distance of 1 m or more on a 20° slope. Test it more than 3 times.
(2) Mark the lower travel structure and the crawler to measure the displacement in the 10-minute time span.
(3) Test it more than two times and record the greater displacement.
3.
Crawler speed
(1) Raise the machine body and mark the crawler. Run the crawler half a turn in advance. Measure the running speed twice
or more.
