Abstract

The invention provides lifting equipment which comprises a body, a lifting part, a hydraulic driving system, a first emergency system and a second emergency system. The first emergency system comprises a stop valve, a first pressure measuring connector, a second pressure measuring connector and a first pressure measuring pipe, an outlet of the stop valve is connected to an oil tank of the hydraulic driving system, the first pressure measuring connector is connected to an inlet of the stop valve, and the second pressure measuring connector is connected to a lower hydraulic connector of the lifting oil cylinder. The first pressure measuring pipe is detachably connected to the first pressure measuring connector and the second pressure measuring connector. The second emergency system comprises a third pressure measuring connector, a fourth pressure measuring connector, a fifth pressure measuring connector and a second pressure measuring pipe, the third pressure measuring connector and the fourth pressure measuring connector are connected to an upper connector and a lower connector of a hydraulic lock installation connector of the supporting leg oil cylinder respectively, and the fifth pressure measuring connector is connected to the hydraulic driving system. The second pressure measuring pipe is detachably connected to the third pressure measuring connector, the fourth pressure measuring connector and the fifth pressure measuring connector.

Description

technical field [0001] The invention relates to a lifting device. Background technique [0002] Lifting equipment is used in various fields, such as aviation food trucks in the field of special vehicles for airports, which are specially used for catering for flights to ensure that flights depart on time. In order to ensure the punctuality of the flight, users have very high requirements on the reliability of the aviation food truck and the efficiency of emergency evacuation. The working reliability of aviation food trucks needs to be guaranteed by the reliable work of mechanical, electrical and hydraulic components. Due to safety requirements, the motion control of mechanical and hydraulic components is realized by the electrical system, and many logical interlock functions are designed for the motion control of various components to prevent misoperation from causing danger to food trucks and flights. [0003] For example, the emergency evacuation procedure of the lifting ...
