[0002] In enterprise production, cranes are used very frequently and the operation actions are very frequent. For the convenience of operation and to meet the production requirements, many enterprises currently use remote control cranes, and the usage is increasing. The operating parts of the remote controller are flexible, which facilitates the use of operators. However, because it is very flexible, various safety accidents will occur if there is accidental touch. For a crane to be operated by a remote controller, except for the components and batteries inside it, the operating parts such as the operating rod are all exposed. Generally, for a bridge crane, one operating rod is required to control the main vehicle to move forward, and one operating rod is required to control the trolley to move and the hoist to lift.
