If crawler crane needs to turn on the slope, some treatments should be taken to the
undulations to form a gentle slope curve (see the following figure), which can prevent
crane’s center of gravity from deviating and load from concentrating on a section of crawler
when crawler crane is traveling over undulations.

Figure 4-42 Treatment of slope
CAUTION
(1) When crawler crane is traveling from the horizontal ground to the slope, if its center
of gravity deviates forwards, stop the crane to adjust the center of gravity.
(2) For the sake of safety, demount the counterweight and boom when the crane is
traveling on a slope with permissible maximum gradient, and the operator does not
know about the ground condition.
(3) The crane can travel with suspended load, providing that the following precautions
are taken:
- The ground surface must be flat and level (no gradient).
- The subsoil must be capable of bearing the crane’s maximum service
weight and the weight of suspended load.
- Only minimum traveling speed is permitted and the boom should be in the
direction of travel.
- Jerky crane movements must be avoided.
- The suspended load must be lashed to prevent it from swinging.
- Steering of crawler is forbidden.
(4) High-speed traveling
Press high speed switch (No. 3 in the figure 4-2), then traveling movements can be
performed at high speed.
Only when the crane is travelling straight without a load, can the high speed switch
be used.
