2results about How to "Lower transport height" patented technology

The present invention provides an engineering machine (10) that can be lowered in height without removing the information acquisition devices (S1 to S3). The engineering machine (10) includes: a holding part (51 to 53) connected to an upper rotating body (30); and a support member (54) held and supported by the holding part (51 to 53) for the information acquisition devices (S1 to S3). The holding part (51 to 53) selectively holds the support member (54) in an upper position and a lower position below the upper position.

The application discloses a kind of light energy storage drives folding modular box.The box includes: first frame and second frame, both are by roof beam, bottom beam and angle column enclosure structure, first frame or second frame inside is provided with functional panel, functional panel includes photovoltaic power generation curtain wall module, folding opening window module and light-shielding curtain wall module one or more;Multiple folding beams are connected between first frame and second frame, one end of each folding beam is hinged with first frame, and the other end is movably connected with second frame through connecting assembly;Unfolding drive assembly, both ends are hinged with first frame and folding beam respectively, for driving folding beam to continue rotating to the position perpendicular to two frames.The application realizes the folding stacking transportation and quick unfolding of the box, reduces labor intensity and operation safety risk, functional panel can be pre-installed in factory, ensures assembly accuracy and sealing performance.
