  • Patent number: 11738973
    Abstract: A gear-track-detachable driving device in a monorail crane for a steep slope includes a driving mechanism, a traveling mechanism, a four-bar linkage mechanism, a connection mechanism, a meshing track plate and transition track plates. The driving mechanism includes driving motors, meshing gears, a bearing rod, and a bearing plate. The traveling mechanism includes traveling wheels, clamping wheels, a shell and telescopic struts. The linkage mechanism includes first and second rockers, a linkage, and a cylinder. The connection mechanism includes fixation plates, a connection plate and connection bolts. When the crane travels to the slope front, the cylinder drives the linkage mechanism to send the meshing gears onto the transition track and adjusts the linkage mechanism into a dead point state, and the telescopic struts are locked. After the crane enters the slope, the meshing gears cooperate with the meshing track plate to provide an auxiliary drive for the crane.

  • Patent number: 11738786
    Abstract: A method that can be implemented relatively easily and inexpensively for monitoring a hazard zone of a level crossing, divides a roadway into a first roadway section and a second roadway section. For this purpose, the method is carried out such that by use of a first radio module, first radio signals are emitted in a first detection region containing at least one part of the first roadway section. By use of a second radio module, second radio signals are emitted in a second detection region containing at least one part of the second roadway section. The hazard zone is monitored indirectly using an analysis which is based both on the first emitted radio signals as well as the second emitted radio signals and which relates to the detection regions.
