The invention provides a lifting and conveying trolley capable of ensuring rigidity around a lifting unit and realizing compactness of the lifting unit. The trolley main body of the lifting and conveying trolley comprises a pair of wheel supporting mechanisms, which support a first wheel of a vehicle to be conveyed; a frame-shaped structure that is connected to the wheel support mechanism; and one or more raising and lowering units that raise and lower the pair of wheel support mechanisms. The frame-shaped structure includes a frame-shaped frame part and an upper plate part, and is open at the lower side of the trolley main body. The lifting unit includes a wheel support and an air spring. The air spring is sandwiched between the wheel support body and the upper plate portion. The wheel support body rotates about one end of the wheel support body rotatably supported by the frame-shaped frame portion along with the extension of the air spring, and deploys to the outside of the frame-shaped structure.
本发明提供一种能够兼顾升降单元周围的刚性确保和升降单元的紧凑化的举升输送台车。举升输送台车的台车主体包含:一对车轮支承机构,所述一对车轮支承机构对输送对象车辆的第一车轮进行支承;框状构造体,所述框状构造体与车轮支承机构连结;以及一个或多个升降单元,所述一个或多个升降单元使一对车轮支承机构升降。框状构造体包含框状框架部和上板部,且在台车主体的下侧开口。升降单元包含车轮支承体和空气弹簧。空气弹簧夹设在车轮支承体与上板部之间。车轮支承体伴随着空气弹簧的伸长而以旋转自如地支承于框状框架部的车轮支承体的一端为中心进行旋转,向框状构造体的外侧展开。
