1.
Turn the key switch to the platform control
position.
2.
Operate the handle to make the vehicle run on
flat pavement at maximum speed, and then
release the handle rapidly.
3.
Measure the braking distance of the vehicle. The
braking distance is required to be less than
0.45m.
The vehicle must be park
on
the
slope
with
maximum gradient at
which it could get on, and shall not slide.
4.
When the vehicle is fully-loaded, the boom has
been extended fully, the vehicle is running on the
flat pavement at the maximum speed, the vehicle
braking distance shall be less than 0.05m after
the handle is released rapidly.
B-7 Testing Traveling Speed (Platform in Lifted
State)
Reasonable driving speed is of great importance to the
safe operation of the machine. The driving function
shall respond to the operations of the operator rapidly
and stably, free from swinging, impact and abnormal
noise.
The machine shall be placed on flat, level and
barrier-free firm ground.
1.
Draw two about 12m lines from the start point to
the end point on the ground.
2.
Turn the key switch to the platform control
position.
3.
Lift the platform off ground by 2.5m and open
the pit protective device.
4.
Operate the control handle and drive the vehicle
from start point to end point.
Result: Run at the speed of 0.8km/h.
5.
Move the high/low-speed selection switch
(tortoise symbol) once, push the control handle to
the maximum position and drive the vehicle from
start point to end point.
Result: Run at low speed (0.8km/h).
B-8 Testing Traveling Speed (Platform in Fully
Retracted State)
Reasonable driving speed is of great importance to the
safe operation of the machine. The driving function
shall respond to the operations of the operator rapidly
and stably, free from swinging, impact and abnormal
noise.
The machine shall be
placed on flat, level and
barrier-free ground.
1.
Draw two about 12m lines from the start point to
the end point on the ground.
2.
Turn the key switch to the platform control
position.
3.
The platform is in the fully retracting state, and
the pit protective devise is also in the retracting
state.
4.
Operate the control handle and drive the vehicle
from start point to end point.
Result: run at high speed (3.2km/h).
5.
Move the high/low-speed selection switch
(tortoise symbol) once, push the control handle to
the maximum position and drive the vehicle from
start point to end point.
Result: Run at low speed (1.6km/h).
B-9 Test Full Lifting and Full Lowering Time
Appropriate lifting or lowering speed is of great
importance to the safe operation of the machine. The
control and response shall be able to respond to the
operations of the operator rapidly and stably.
Select a barrier-free testing area with firm and level
surface.
1.
Release the emergency stop button, and turn the
key switch to the lower platform control.
