Transporting means propelled one kind

The present invention discloses a traveling-type transporting device, comprises two main beams and two side beams to form a rectangular rack, the rack is attached to the lower transport platform, the transport platform and the chassis are connected by four columns , four column base has travel wheels; said main chassis beam along the beam can be mounted slidably moving the main girder; moving the beam structure: by a first slider and the second slider roller slidably mounted between two main beams, connected to the first slider and the second slider is fixed by connecting beams; the four hydraulic lifting column for the column; according to a first slider and a second beam the slider is fixed to the extension arm, the extension arm below the lifting mechanism is also attached. The present application has a bottom transport platform, a large space, a large transport loading, and to their lifting, the use of large, further comprising four hydraulic lifting column, the height of the rack can be adjusted, thereby adjusting the lifting height of the lifting mechanism.
