PERFORMANCE CRITERIA 2D0AX002
Boom cylinder speed
• Engine: Maximum R.P.M.
• Hydraulic oil temp.: 50°C to 60°C (122°F to 140°F)
• Measuring attitude: Completely retract the arm cylin-
der, and fully extend the bucket cylinder.
• Next, measure the time required for the bucket to
reach its highest elevation point (lowest point) from its
lowest point (highest point) at rest on the ground. (ex-
clusive of cushion operating time).
Arm cylinder speed
• Engine: Maximum R.P.M.
• 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 arm cylinder, fully extend the
bucket cylinder, position the arm horizontally, and rest
the dozer blade on the ground.
• Measure the time required for the arm cylinder to move
from the fully retracted position to the fully extended
position, and vice versa.
Bucket cylinder speed
• Engine: Maximum R.P.M.
• 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 arm cylinder, position the arm
horizontally, and rest the dozer blade on the ground.
• Measure the time required for the bucket cylinder to
move from the fully retracted position to the fully ex-
tended position, and vice versa.
Dozer blade cylinder speed
• Engine: Maximum R.P.M.
• Hydraulic oil temp.: 50°C to 60°C (122°F to 140°F)
• Measuring attitude: Using the hoe attachment, lift up
the dozer blade end of the excavator.
• After raising and lowering the dozer blade one full
stroke each, measure the time required per stroke in
each direction.
