d
Slew Brake
1
The slew brake performance is measured at the
minimum slew position.
Mark the turntable bearing and lower ring.
Note:
The person must stand well out of the machines slew
radius on the front side, and also to confirm that no other
personnel are in the vicinity.
2
Rotate the upper body and when the machine has
completed its full initial start rotation, indicate to the
operator when the two marks will coincide on the
next rotation. The operator then moves the lever to
neutral.
3
After the swinging has stopped, measure the
distance between the two indicating marks.
e
Slew Lock Characteristics.
1
The conditions for checking this is to load the
bucket with soil at the maximum working radius.
Then drive
up a slope of 20° , then set the
attachment to a 90° position relative to the
direction of travel.
2
Confirm with an angle gauge that the vehicle is at
20° and mark the turntable bearing and lower ring.
3
Stop the engine and remove the key. Measure the
distance the Upper Slew Body has moved relative
to the lower frame after 30 minutes.
f
Natural Internal Leakage, natural ram drop.
1
The conditions for checking are that the dipper is
fully open with the bucket open.
2
Using a marker pen, mark the wiper seal on the
bucket ram piston rod, then mark the wiper seal on
the dipper ram rod.
3
Gently raise the dipper till the bucket is 2 m above
ground.
4
Make a mark 100 mm from the wiper seal on the
boom ram rod.
5
Switch the engine off and remove the key. Wait 10
minutes then measure the distance from the ground
to the bucket.
Measure the movement of each:-
Ram Rod
Boom
Dipper
Bucket
