ON position, the engine speed may accelerate and

the travel speed may suddenly increase.

•

Always avoid traveling over obstacles or raised

areas if possible. Traveling over obstacles or raised

areas could result in loss of control or damage to the

machine. If you must travel over raised areas,

always travel at a slow speed with the work

equipment as close the ground as possible. Avoid

any sharp turns or sudden stops.

•

During travel, always maintain a clear distance

from people or surrounding objects.

•

Always check to be sure surface areas such as

bridges or road ways will support the weight of the

machine.

•

Before traveling on public roads or in publicly

owned areas, always check with the relevant

authorities and follow their instructions. Failure to

do may result in damage, loss of control, fines or

punishment.

•

Always be extra careful when traveling in tunnels,

under bridges, near utility lines or in places with

ACN0954

limited weight, height or where clearance is a

problem. Operate slowly and be extremely careful

not to let the machine or work equipment come in

contact with anything.

Traveling With a Reversed Carriage

Traveling with the carriage reversed could pose a hazard.

Travel direction for all Sany excavators is indicated on the

inside of the track motor with an arrow. Although Sany does

not recommend traveling with the carriage reversed, below

is a list of some basic rules to follow when traveling with a

reversed carriage:

•

Always keep in mind the travel lever controls will

be working in the opposite direction from normal

travel.

•

Before moving your machine, always check the

Fig. 2-69

position of the carriage as it relates to the travel

levers.

•

If you will be traveling in areas where the machine will be exposed to surrounding hazards, rough surfaces

or tight maneuvering, you may want to travel with the carriage in the normal position.

Traveling on Sloped Areas

Traveling on sloped areas with an excavator always poses a

hazard.Work equipment position, counterweight location

and carriage position all effect the stability of the machine

when traveling on sloped areas. Repositioning of the work

equipment, carriage or counterweight while traveling on

these surfaces will change the center of gravity location on

the machine. In order to prevent tipping, loss of control or a

rollover, it is important to follow some basic, simple rules

when traveling on sloped areas.

20 - 30 cm

•

Never turn the ignition switch off when traveling up

(8 - 12 in.)

or down a slope. If the engine should stop, lower the

ACN0955

work equipment to the ground immediately.

Fig. 2-70

•

Always keep the work equipment approximately 20

to 30 cm (8 to 12 in.) above the ground. Avoid moving the work equipment or shifting the position of the

carriage when traveling on a slope. Doing so will change the center of gravity on the machine.

•

Always face the front of the operator cab uphill when traveling up a slopes.

•

When traveling down slopes, set the operator cab

facing downhill.

•

Always check the firmness of the surface on the

slope before you attempt to travel on it.

20 - 30 cm

(8 - 12 in.)

ACN0956

•

If you will be traveling up an extremely steep slope,

extend the work equipment to the front of the

machine to help balance the machine.

•

Keep the work equipment approximately 20 to 30

cm (8 to 12 in.) above the ground and travel at a

20 - 30 cm

slow speed. When traveling downhill, lower the

(8 - 12 in.)

engine speed, keep the travel at a low speed.
