Tire pressure alarm system of crane

Abstract

The invention discloses a tire pressure alarm system of a crane. The tire pressure alarm system of the crane comprises a detector I, a detector II, a detector III, a detector IV, an alarm device I andan alarm device II. The detector I, the detector II, the detector III and the detector IV are serially connected. The alarm device I is connected with the detector I and the detector III together. The alarm device II is connected with the detector II and the detector IV together. The alarm device I and the alarm device II are parallelly connected. Pressures of four tires of the crane can be monitored at any time, and a situation that the pressure of one tire is less than other three or other two pressures does not occur, and a situation that a carried heavy object is fallen is avoided from occurring in a working process.

Description

technical field

[0001] The invention relates to an alarm system, in particular to a tire pressure alarm system for a crane. Background technique

[0002] The most important thing when a mobile crane is working is to fix the machine smoothly. Usually, the staff use the hydraulic prop support under the car body to support and fix it, but sometimes the staff do not use the prop support because of the short use time. Fixed, this requires the crane to maintain a very good balance, the tire pressure of the crane is very important, if the pressure of one tire is lower than the pressure of the other three or the other two, it is easy for the crane to transport the weight when it is working. Objects fall, causing great economic losses. Contents of the invention

[0003] Aiming at the problems existing in the above-mentioned prior art, the present invention provides a tire pressure alarm system for a crane, which can monitor the pressure of the four tires of the crane at all times,...
