PERFORMANCE CRITERIA
2D0AX002
Swing cylinder speed
• Engine:
Maximum R.P.M.
• Hydraulic oil temp.: 50°C to 60°C (122°F to 140°F)
• Measuring attitude: Same as that for measuring slew
time
• While swinging the boom from left (right) to right (left),
measure the time required for a full stroke in each di-
rection. (exclusive of cushion operating time).
Natural cylinder drop
Boom, arm bucket, dozer blade, bucket tip
• Engine:
Stopped
• Hydraulic oil temp.: 50°C to 60°C (122°F to 140°F)
• Measuring attitude: With the bucket in a no-load state,
completely retract the dozer blade and arm cylinders,
and then fully extend the bucket cylinder and make
adjustments so that the boom foot pin and bucket pin
are at the same height.
• Maintain this attitude for 5 minutes and then measure
the change in rod length and the distance that the
bucket tip moved.
Swing
• Engine:
Stopped
• Hydraulic oil temp.: 50°C to 60°C (122°F to 140°F)
• Inclination angle:
15°
• Measuring attitude: Same as that for measuring slew
time
• Rotate the upper structure so that it is directly abeam
of the grade, and then measure the change in rod
length after 5 minutes has passed.
Spanner cylinder speed
• Engine:
Maximum R.P.M.
• Hydraulic oil temp.: 50°C to 60°C (122°F to 140°F)
• Measuring attitude: Excavator body to be raised using
both the hoe attachment and the dozer blade.
• Measure the time required for the spanner cylinder to
move from the fully retracted position to the fully ex-
tended position, and vice versa.
