CAUTION
(1) High speed is not allowed when both left and right crawlers are turning at the same
time.
(2) When there is a need to stop traveling or steering, return the travel gear pedal to
neutral (zero) position, the traveling brake will be activated automatically.
(3) When the crane is traveling with a load for a long distance, ensure that the boom is
located straight ahead, and the traveling reducer is behind the slewing table.
b) Traveling on a slope
Crawler crane travels forward, and left control lever is placed in neutral (zero) position.
When the crane is traveling uphill, the engine speed must be controlled within medium
speed range. When crawler crane is traveling on a slope with maximum permissible
gradient, it can only be fitted with basic boom. And the counterweight should be in the
direction of uphill, the drive sprocket is the direction of downhill. While when it goes
downhill, the drive sprocket should be in the direction of uphill.

For reference only.
Operators manual should be consulted and adhered to.
