CLIMBING CRANE LOAD LIMITER Russian patent published in 2013 - IPC B66C23/88 B66C15/00 G01L1/00 

FIELD: transport.

SUBSTANCE: invention relates to machine building. Load limiter comprises force transducer and electronic device to generate warning signal of interlocking the load lifting mechanism actuator in machine reloading. Force transducer converts the force acting threat into pressure and, further, into electric signal and comprises base and loose piston separated by layer of elastomer. Transducer is composed of, particularly, false cradle of automatic hydro lifter or is adapted for fitting under traveler winch drum support body and may be shaped to a ring or parallelepiped with holes for attached at the machine. Said transducer can incorporate several pressure transducers to define mean load and load application point with generation of data or control signals. Clearance between sidewall of loose piston and base inner sidewall is selected to prevent extrusion of elastomer while its length is selected to protect against lateral loads. Electronic device is built around microcontroller and incorporates output device and wire or wireless interface.

EFFECT: impact and vibration resistance, expanded applications, higher safety.
