3.24 OPERATION DURING TRAVELLING A HOISTED LOAD
3.24.1 PRECAUTIONS IN OPERATION DURING TRAVELLING A HOISTED LOAD
Travel with a lifted load is in principle dangerous because it is very unstable.
If travelling a hoisted load is unavoidably performed, strictly observe the range described
in "List of gross rated load for travelling hoist" and travelling hoist posture. "List of gross
rated load for travelling hoist" shows values of load the machine can hoist during travelling
on the level, solid ground.
Unless these precautions in traveling a hoisted load are observed, serious physical injury
may be caused.
[1] GROSS RATED LOAD FOR TRAVELLING A HOISTED LOAD AND PRECAUTIONS IN
WORKING RANGE
When performing travelling a hoisted load, be sure to observe strictly the gross rated load shown in
the table below.
Item Remarks
Boom length
10.5m (three stage boom)
or less
Rated total load
See the list of gross rated
load for travelling a hoisted
load.
[2] PRECAUTIONS IN WORK PLACE
As there is danger of the machine tipping over on the following grounds and places, do not approach
them or perform travelling a hoisted load.
Check the condition of the road surface and ground. Arrange a traffic guide for a dangerous place
or a place of poor visibility.
• Soft ground such as a slope and marsh, ground with many obstacles, bumpy ground such as a
riverbed, ground with difference in level
• Near deep grooves and road shoulder
• In water and shallows, snowy area, frozen road surface
[3] PRECAUTIONS IN OPERATION
Never perform the following travelling operation because doing so may cause the machine to tip
over.
When operating, be sure to sit on the driver seat and carefully perform the operation during travelling
a hoisted load.
• Never perform the crane operation during travelling. Keep the travelling hoist posture.
• Do not raise the load to a high position. Hold it near the ground so that the load does not sway.
• Do not start and stop suddenly, and do not make a sudden direction change. Doing so is dangerous
because the load sways.
Be sure to set the travelling speed to "Low speed (1st speed)" to keep the engine speed low and
slowly travel.
• Do not travel over an obstacle. The machine is likely to tip over. Be sure to travel on a course clear
of obstacles.
