Features of the Modernization of the Control Systems of Hoisting Cranes at NPP
- 17 Downloads
A method of partial modernization of the control systems of special hoisting cranes operating at NPP that is cheaper, in terms of the cost of and time required for complete replacement than the alternative of complete replacement, and meets the regulatory requirements is proposed. The method consists in equipping the cranes with multi-functional autonomous devices, such as operational parameter monitoring systems, anti-collision systems, load control, locking control, and guidance in one or another combination depending on which required functions are not being currently realized. The indicated devices are compatible with one another and can be quite simply built into existing crane control systems irrespective of their type (relay-contactor, frequency-controlled). A description of the devices is given. The proposed autonomous devices (systems) can also be effectively used in designing new cranes.
