Provided is a lateral rollover limit detection system which can determine the lateral rollover danger of a structure for which the weight or the weight distribution has not been clarified. A placement board, springs, and detection object are provided as a ...

A center-of-gravity detecting system (100) includes a motion detector (14) for detecting a vertical motion of a travelling object in a self-weight direction during travel and a horizontal motion of the travelling object in a widthwise direction during trav...

An inclination angle calculation device (100) comprises a motion detector (14) for detecting motions of a traveling object during travel, in two directions included in a cross-section surface of the traveling object, the two directions being orthogonal wit...
