The invention relates to a hydraulic elevator with an emergency protection system. The hydraulic elevator comprises a base, a bearing platform, a supporting arm, a driving mechanism and a safety protection system, wherein the safety protection system comprises a positioning strip, a flexible sheath, a contact strip, a sensor and a processor; the positioning strip is arranged on the peripheral direction of the bearing platform and closed at the bottom of the bearing platform by the flexible sheath, and an empty chamber is formed in the flexible sheath; the contact strip is arranged on the peripheral direction of the flexible sheath and positioned in the flexible sheath; a gap exists between the contact strip and the positioning strip, the contact strip is positioned at the middle lower part of the flexible sheath, and the two sides of the contact strip are fixedly connected with the side wall of the empty chamber; the processor is communicated with the driving mechanism. After the flexible sheath is acted by an external force, the contact strip deforms along with the flexible sheath and makes contact with the positioning strip; after the sensors receives information, the information is sent to the processor, and the driving mechanism stops working at once. The hydraulic elevator can stop lifting in time or at any time, so that accidents are prevented.
