The invention relates to a wheeled crane, comprising: a frame comprising a first frame section, a second frame section and a mounting mechanism for horizontally and rotatably connecting the second frame section to the first frame section; the hoisting equipment comprises a rotary table mounted on the second frame section and a suspension arm connected with the rotary table, and one end, far away from the rotary table, of the suspension arm is supported on the second frame section; the alarm system comprises a sensor used for detecting the relative rotation angle of the first frame section and the second frame section, an alarm device electrically connected with the sensor and a control device used for controlling the alarm device to be turned on and turned off, and the control device is configured to control the alarm device to be turned on when the angle detected by the sensor is larger than a preset value. The frame of the wheeled crane is divided into the first frame section and the second frame section which can be horizontally and rotatably connected, so that the road trafficability of the wheeled crane is improved. And the situation that the relative rotation angle of the first frame section and the second frame section is too large, interference is generated, and consequently parts are damaged can be prevented.

    本公开涉及一种轮式起重机,包括:车架,包括第一车架段、第二车架段以及用于将第二车架段可水平转动地连接在第一车架段上的安装机构;起重设备,包括安装在第二车架段上的转台和与转台连接的吊臂,吊臂的远离转台的一端被支撑在第二车架段上;以及报警系统,包括用于检测第一车架段和第二车架段的相对转动角度的传感器、与传感器电连接的报警装置,以及用于控制报警装置开关的控制装置,控制装置配置成在传感器检测的角度大于预设值时,控制报警装置开启。将轮式起重机的车架分为可水平转动连接的第一车架段和第二车架段,提高轮式起重机的路面通过能力。也可以防止第一车架段和第二车架段的相对转动角度过大而产生干涉,因而造成零部件损坏。
