The invention discloses a centrally-mounted axle crane which comprises a towing hook, a trailer chassis, a lifting supporting piece, a suspension arm, wheels and a driving mechanism, the wheels are transversely and rotatably installed below the trailer chassis, and the towing hook is installed on one side of the trailer chassis; the dragging rod is mounted below the trailer chassis; the lifting supporting piece is installed on the trailer chassis, the distance between the lifting supporting piece and the trailer chassis is adjustable, and the lifting supporting piece is used for supporting the trailer chassis. The driving mechanism and the suspension arm are both mounted on the trailer chassis, the length of the suspension arm is adjustable, and the driving mechanism is used for changing the length of the suspension arm; and when the length of the suspension arm is shortest, the gravity centers of the suspension arm and the driving mechanism are on a vertical plane on which the rotating axis of the wheels relative to the trailer chassis is located. A crane is not used in cooperation with a traction vehicle, and therefore the manufacturing cost is reduced.
本发明公开了一种中置轴吊车，包括拖钩、拖车底盘、升降支撑件、吊臂、车轮和驱动机构，其中：车轮横向转动安装在拖车底盘下方，拖钩安装在拖车底盘的一侧；拖拉杆安装在拖车底盘的下方；升降支撑件安装在拖车底盘上，且升降支撑件到所述拖车底盘的距离可调并用于对拖车底盘进行支撑；驱动机构和吊臂均安装在拖车底盘上，吊臂的长度可调，驱动机构用于改变所述吊臂的长度；所述吊臂长度最短时，吊臂和驱动机构的重心在所述车轮相对拖车底盘转动的轴线所在的竖直面上。本发明公开不含吊车与牵引车辆配合使用进而降低制造成本。
