In addition, no zero-point adjustment, and data in- put thru interface counter-indica- tion/message on display panel are available for easier and certain set- ting of operating conditions and LMI function. Of course, "present lifting load", "rated load", "load ratio", "working radius", "boom angle", ther, the LMI functions that if lifting condition reaches peril zone, as in- termittent warning buzzer is given operator together with a warning...

Folding type axle beam ends Longer carbody axle beams with folding type ends are designed, and these four (4) ends reach up to axle box end of crawler side frames for better fitting between axle beams and crawler side frames. And, it is able to eliminate their assembling/disassembling, and axle beam-end pins can easily be pulled up and down from outside. "Hook-on" design is taken for their mounting on upper revolving frame, also taken to load boom exten- sion (s) onto counterweights when Optional rigid guard A detachable-ease rigid guard is op- tionally available i/o standard, and it is possible...
