Introduction
It is important before taking measurements that control
conditions are maintained.
a.
Position the machine on a level safe site.
b.
Adhere strictly to the safety operation.
c.
Confirm the setting when an adjustment is made.
The items to prepare are:-
a.
The check sheet
b.
Tape measure
c.
Dial gauge with magnetic stand
d.
Angle gauge
e.
Chalk
f.
Stop watch
Basic Measurement Conditions
When checking the performance value, certain conditions
should be fulfiled:-
a.
The machine should be in the
S
. Mode.
b.
The hydraulic oil temperature should be 45°C-55°C.
c.
The engine speed should be within ±50 rpm of the
Reference Value.
d.
The hydraulic equipment should be operated several
times before testing.
e.
The operation to be measured should be operated
three times and an average taken.
f.
Measure on level hard ground.
These consist of two basic types of measurement:-
1. Speed Measurements
a.
Bucket Ram Speed.
b.
Dipper Ram speed.
c.
Boom Ram Speed.
d.
Slew Speed.
e.
Travel Speed.
2. Other Measurements
a.
Travel Linearity.
b.
Slew Backlash.
c.
Lateral Movement in turntable bearing.
d.
Slew Brake.
e.
Slew Lock Characteristics.
f.
Natural Internal Leakage, Natural Ram Drop.
g.
Amount of Hydraulic Oil squeezed out by each ram.
