The invention discloses a hydraulic height limiting device and a crane, and relates to the technical field of cranes. The hydraulic type height limiting device is used for the hoisting device, the hoisting device can stretch out and draw back and/or swing, and the hydraulic type height limiting device comprises a hollow pipe and a pressure sensor. The upper end of the hollow pipe is connected to the hoisting device, the lower end of the hollow pipe is connected with the pressure sensor, the hollow pipe is used for being filled with liquid, and due to the fact that the liquid pressure intensity is in direct proportion to the depth, when the height of the upper end of the hollow pipe changes, the liquid pressure intensity of the lower end of the hollow pipe changes. The pressure sensor is connected to the lower end of the hollow pipe and can measure the liquid pressure at the lower end of the hollow pipe, and then the height of the top end of the hoisting device is obtained according to the liquid pressure, so that an operator can obtain the height of the top end of the hoisting device in time and adjust the height of the hoisting device in time; and the top end of the hoisting device is prevented from touching other facilities in the hoisting process, so that the safety of the hoisting device is improved.
本发明公开了一种液压式限高装置及吊车,涉及吊车技术领域。液压式限高装置用于吊装装置,吊装装置能够伸缩和/或摆动,液压式限高装置包括中空管和压力传感器。中空管的上端连接于吊装装置,中空管的下端连接压力传感器,中空管用于在其内部充满液体,由于液体压强与其深度成正比,当中空管的上端的高度改变时,中空管的下端的液体压强大小也会改变,压力传感器连接于中空管的下端并能测量中空管下端的液体压强,进而根据液体压强大小获取吊装装置顶端的高度,从而使操作人员能够及时获取吊装装置顶端的高度,并对吊装装置的高度进行及时调整,避免在吊装过程中吊装装置的顶端触碰到其他设施,提高了吊装装置的安全性。
