A high-safety induction-type crane is composed of the main crane body and the induction-type proximity switches installed to both end of the end sills at both sides of main crane body. Said proximity switches are serially connected to the running controller of crane.
Description
technical field [0001] The present application relates to cranes, in particular to rail-mounted cranes. Background technique [0002] Present track traveling crane such as gantry crane, bridge crane etc., its structure all comprises parts such as main girder and the end girder of both sides, and rail wheel is installed on the end girder so that move on track. Because current rail cranes are not equipped with anti-collision safety devices, accidents are prone to occur. For example, a gantry crane, if someone approaches the track and the crane suddenly moves, it is easy to collide with people, causing casualties. For example, there are many bridge cranes installed in large workshops, and they run on the same track. If the operation is not careful, it is easy to cause the two to collide. Contents of the invention [0003] In order to solve the problem of the safe operation of the existing rail walking crane, the application provides an induction type safe operation crane. ...
