CONTROL SYSTEM OF LOAD-LIFTING CRANE (VERSIONS) Russian patent published in 2009 - IPC B66C13/18 B66C23/88 B66C15/00 

FIELD: transport.

SUBSTANCE: proposed control system contains the onboard microprocessor control unit with actuators connected thereto, crane operating parameters pickups and controls. The proposed system incorporates means identifying lifted and moved cargo representing a reader of bar codes applied on the cargo, or a radiolabel attached to the cargo, to allow locking the cargo, exceeding the crane lifting capacity, lift and move. The system can contain cargo position pickups to automatically guide the tool to be clamped to the cargo. In compliance with the second version, manual input of the identifier or cargo parameters into this system, and, if required, the coordinates of a final point cargo transfer cargo. Note here that the system incorporates appropriate means preventing the crane overload and optimising cargo transfer trajectories. In compliance with the third version of the control system, the said system can block releasing the cargo from the clamping tool depending on current value of the crane load, speed of move and/or spatial position. In compliance with the fourth version, the control system is equipped with wire or wireless means of transmitting signals from a person, outside the load-lifting crane, to the onboard microprocessor control unit for them to be converted into warning light and/or sound data signals and/or to signals blocking the crane motion.

EFFECT: increase in safety of crane operation, its efficiency and ease of control.
