Overload Limiter for Overhead Cranes and Jib Cranes

Brief description	While designing cranes, their maximum load capacity is determined for position of a crab in the most dangerous section of a crane metal structure (for an overhead crane it is in the middle of the span for moving of the crab). While moving of the crab with cargo away from the most dangerous section, exists a possibility of safe increase of load capacity of cranes, providing that there is the overload limiter on the crabs, which determined the position of the crab with cargo. The overload limiter of variable load capacity was designed. It determined the position of the crab with cargo on the crane metal structure and allows safe increase of load capacity.
Readiness degree	Methode 11
Development phase	The circuit diagram of the overload limiter of variable load capacity, the design technique, calculation procedure and procedure of key parameters selection were developed.
Type of innovation	productivnie
Intellectual property rights	Patent of Ukraine for utility model UA # 33054 as of June 10, 2008 is received. Application # u 2008 01325 as of February 04, 2008. Published on June 10, 2008, bull. #11.
Application field	industry 11, building 11
Application field (more info)	Load lifting equipment with crabs, moving horizontally on the crane metal structure.
Competitive advantages	novelty 11
Competitive advantages (more info)	Creation of conditions for safe load capacity increase of cranes while moving a crab away from the most dangerous section of the crane metal structure. For example, while moving a crab a quarter span from the end of the frame of an overhead crane, it is possible to increase its capacity by 60% and even more by smaller moving pace.
