The invention discloses a resistance type height limiting device and a crane, and relates to the technical field of cranes. The resistance type height limiting device is used for the hoisting device, the hoisting device can stretch out and draw back and/or swing, and the resistance type height limiting device comprises a displacement conversion device and a sliding resistance assembly. One end of the displacement conversion device is connected with the hoisting device, the other end of the displacement conversion device is connected with the sliding resistor assembly, and the displacement conversion device can convert the height of the hoisting device into the displacement of the sliding resistor assembly to change the resistance of the sliding resistor assembly and obtain the height of the hoisting device, so that the height of the hoisting device can be measured; and the height of the hoisting device is measured more accurately, so that an operator can know the height of the hoisting device in time, the hoisting device is prevented from touching other facilities, and the safety in the hoisting process is improved.
本发明公开了一种电阻式限高装置及吊车,涉及吊车技术领域。电阻式限高装置用于吊装装置,吊装装置能够伸缩和/或摆动,电阻式限高装置包括位移转换装置和滑动电阻组件。位移转换装置的一端连接吊装装置,位移转换装置的另一端连接滑动电阻组件,位移转换装置能够将吊装装置的高度转换为滑动电阻组件的位移,以改变滑动电阻组件的电阻,并获取吊装装置的高度,从而能够测量吊装装置的高度,对吊装装置的高度测量更精确,使操作人员及时明确吊装装置的高度,避免吊装装置触碰到其他设施,提高了吊装过程中的安全性。
