  • Patent number: 8827091
    Abstract: [PROBLEMS] To provide a rotating frame of an upper rotating body such that total productivity can be improved, the cost can be reduced, and model change can be facilitated. [MEANS FOR SOLVING PROBLEMS] Many models having different lifting capacities are divided into a plurality of classes each including a plurality of models. A rotating frame 17 is determined on the basis of the model having the largest lifting capacity in each class. An upper rotating body is constructed using the rotating frame 17 as the base. In addition, each of winches 5 to 7 is mounted on the rotating frame by using a mounting structure standardized in the same class. On the other hand, left and right deck frames 18 and 19 are divided into sections on which different pieces of equipment are mounted, and the sections are separately attached to the rotating frame 17.

  • Patent number: 6520358
    Abstract: In the present crawler crane, an engine including a power plant for supplying driving pressure oil to a main winding drum, an auxiliary winding drum and a third drum is mounted on either left or right side of a revolving frame, a counterweight having a front side formed into a recessed surface is mounted at the rear of the main winding drum, the auxiliary winding drum and the third drum, and a boom rising and falling drum is installed within the recessed portion, thus making it possible to mount the third drum which has the same shape as the main winding drum and the auxiliary winding drum, for example. It is possible to provide a crawler crane capable of performing operation for versatile uses.

  • Patent number: 6474485
    Abstract: A crawler traveling type working machine, comprising: a lower traveling body provided with crawlers on left and right sides; an upper rotating body mounted on the lower traveling body through a rotating means, the upper rotating body having a first counter weight; and a second counter weight interposed between an upper part of the lower traveling body and the rotating means. With this constitution, the stability of the working machine is excellent, the obstacle avoiding function when the upper rotating body rotates is excellent, and the rear rotating radius is smaller than the normal working machine of an upper class. Therefore, the working machine can be used as a working machine of an upper class.

  • Patent number: 5293225
    Abstract: A color camera apparatus comprises an image pickup element having a stripe/mosaic type color filter and photo-electrically converting an arriving optical image so as to obtain at least a signal including a brightness component and a color component multiplexed with each other. And, the apparatus comprises an A/D converter for digitizing above multiplexed signal, and a brightness signal processing circuit which separates the brightness component from the multiplexed signal and carries out an aperture correction by means of a delay element having a delay amount corresponding to two horizontal scanning period. And further, the apparatus comprises a color signal processing circuit which separates the color component from the multiplexed signal so as to obtain two line-sequential color difference components through a predetermined arithmetic procedure.
