Speed Measurements
a
Bucket Ram speed.
The conditions for checking are that the Dipper should
be level.
Measurement is of the time it takes the bucket to fully
open and close from each end of the stroke
b
Dipper Ram speed
The conditions for checking are that the Dipper should
be level with the bucket open.
Measurement of the time it takes the Dipper to open
and close from each end of the stroke.
c
Boom Ram speed
The conditions for checking are that the Dipper and the
bucket are open.
Measurement of the time it takes for the boom to go
from a fully raised to fully lowered position.
Note:
Place a wooden block where the Dipper would make
contact with the ground, so as to prevent a shock loading of
the arm, when it is lowered.
d
Slew Speed
The conditions for checking are that the attachment is
facing forwards and that a vertical line is chalked on the
turntable bearing and lower ring, then place the
attachment in the minimum slew position.
Rotate the upper framework and after one complete
rotation, then measure the time it takes for the next
rotation.
e
Travel Speed
The conditions for checking are that the main unit is
jacked up, then marks are made on the Traction Motor
and side frame. Rotate the sprocket two times or more
to warm the motor then, record the time it takes for the
motor to complete ten revolutions.
Measurement should be done with the machine in each
mode, low, medium and high speed and three
measurements in each direction in each mode should
be done to obtain an average.
