DANGER
(1) Before transportation, retract the crawler carrier, lay down the A-frame and place
main boom pivot section flatly, and finally lock the slewing mechanism by slewing
fixing pin.
(2) When drive the basic machine off or onto the low-loader, a steel plate (with an
inclination less than or equal to 8° to the ground) should be used to connect the
low-loader to the ground. The angle of main boom pivot section should be less than
30° in order to protect crane against overturning.
