Ammann ASC 130 - Driving with Vibrations on Compacted and Hard Material

113ASC110/ASC130/ASC150/ASC200/ASC250
OPERATING INSTRUCTIONS
After releasing brakes and short-
circuiting the travel hydraulic circuit,
all brakes are out of operation!
Use unimpaired towing cables or
towing bars of sufficient capacity -
dimensioned to weight 1.5 times
higher than weight of the towed
machine. It is not permitted to use
chains for towing.
No persons can be present on the
machine with non-working engine.
It is necessary to keep the deviation
from the straight towing angle as
little as possible. Maximum deviation
is 30 degrees.
The movement during towing must be
smooth. Do not exceed towing speed
of 2 kmph (1.2 mph). Do not tow the
machine for distances longer than
300 m (0.19 miles).
The towing machine should be equal
by size to the damaged machine. It
must be sufficiently powerful (towing
power), heavy and have sufficient
brake effect.
When towing downhill using a cable,
it is necessary to connect another
towing machine to the rear part of the
damaged machine. This will prevent
uncontrolled movement of the
damaged machine.
Do not start the engine during towing.
The bogged roller may be pulled out
for short distance, if the engine is
running and the driving unit and
steering are functional. The drive on
the towed roller must steer the roller
in the dragging direction.
If the engine is stopped. Avoid
damaging inoperable power train,
steering and brake system.
NOTE
These are general requirements for safe towing of the
damaged machine under standard conditions. Any spe-
cific conditions that may occur during towing must be
consulted with a machine distributor.
2.9.2. Driving with vibrations on compacted
and hard material
When driving with vibration on more compacted subgrade
material, so called vibro-strike may occur.
The same applies when driving with vibration on hard
materials (such as stone aggregate). This situation results
in increased transmission of vibrations to the machine
frame and the driver’s stand. It can be partially reduced by
increasing travel speed or by changing vibration parame-
ters (using smaller amplitude).
Note:
Emission data of vibration acceleration will be different
during driving with vibration on subgrade material other
than the one specified in ”Specification manual” - Sani-
tary data.
! NOTE !
If working with the machine under conditions
exposing the operator to increased vibrations
cannot be avoided, the keeper of the machine must
modify working procedures so that it is not harmful
to the driver’s health.
