CAUTIONS WHEN TRAVELLING
Always observe the following to prevent serious injuries and
accidental death when moving the machine.
• Set the machine to the travelling posture in the right figure.
Refer to the preceding subsection “CAUTIONS ON MACHINE
FORWARDING/REVERSING AND SLEWING”.
• Do not attempt looking sideways or other dangerous act when driving.
• Do not over speed, start moving/stopping/slewing suddenly, or
meander since such acts are dangerous.
• During travelling, keep an adequate distance from persons,
structures and other machines to prevent any contact accident.
• Avoid moving over any obstacle. Travel as slowly as possible
when moving over an obstacle for unavoidable reason. Since the
machine tends to tumble more easily in the lateral direction rather
than in the longitudinal direction, never attempt to move over an
obstacle that will cause the machine to inclined to leftward or
rightward.
• When travelling on a rough terrain, keep the vehicle speed at low
level to avoid tumbling and also avoid any abrupt change of
travelling direction. Such may cause the machine to lose balance
or damage the machine or nearby object.
• When running on a bridge or crossing over a structure, check the
withstand strength of the bridge or viaduct against the machine
mass beforehand. Further, when running on a public road, check
with the competent authorities and follow their instructions.
• When operating the machine in a place where machine height is
restricted such as in a tunnel, in a building, under an overpass or
cables, pay close attention to prevent the machine and crane from
coming into contact of those objects and operate the machine
slowly.
BE CAREFUL WHEN TRAVELLING OVER SLOPE
ALWAYS observe the following to prevent serious injuries and death
accidents when travelling over a slope for unavoidable reason.
• When running on a slope, be sure to store the hook block in the
hook holder at the front end of the upper slewing body to form a
running posture. Any simplified fixation of the hook at the tip of
boom gives rise to the risk of loosening during running.
Refer to the descriptions under “Operation 3.6 Machine Travelling
Posture” for the travelling posture of the machine.
• When running on a slope having an inclination of 10 degrees or
more, climb the slope in the reverse direction and run downhill in
the forward direction. Thus, always allow the machine front to face
the valley when running on a slope. Climbing the slope in the
forward direction and going downhill in the reverse direction cause
the machine to be unstable, giving rise to the risk of tumbling or
lateral skidding.
• When travelling on a slope, face the machine perpendicular to the
slant face and never change the direction or travel transversely.
Practice safe travelling by for instance lowering to the plain land
and divert.
• Always keep such condition during running that the machine can
stop any time when it slips or becomes unstable.
• When running downhill, lower the engine revolution and set the
running lever close to the neutral position and run in a low speed.
• When running on a ground covered with grass and leaves or on a
wet steel plate, keep the speed to minimal. If the ground in such
condition is inclined only slightly, it is extremely slippery.
• If the engine comes to a sudden stop, immediately return each
operating lever to its neutral position, and then restart it.
