Technical Field

The invention relates to the field of lifting appliances, in particular to a lifting reinforcing device for a supporting angle disc of a crane.

Background

The crane angle supporting disc processed in a factory is usually hung up for airing or air drying, some angle supporting discs have larger self weight and need to be turned over during installation, disassembly and maintenance, the threaded connection part between the extension bar and the angle supporting disc can be loosened after long-time use, and the loosened part is difficult to find; meanwhile, the angle supporting plate is easy to bend or break the extension bar in the overturning process, so that the angle supporting plate is damaged and even has safety accidents.
