SBUC Application Example Hydraulic Cranes
SBUC with safety-related software functions
SBUC controls smooth management of сrane hydraulic executive mechanisms and рrotects from damage and overturning.
The system executes all functions of rated capacity limiter system and corresponds to safety requests of Rostehknadzor.
Example of a complete set of SBUC system for hydraulic crane
— drive management, including speed control and safety functions;
— rated capacity limiter system;
— monitoring load and geometry variables of crane;
— monitoring parameters of crane engine and hydraulics (engine oil pressure, engine coolant temperature, hydraulics oil temperature and etc.);
— engine control via CAN bus;
— control of hydraulic oil pressures;
— display of video signals from 2 color cameras (workspace/rear-view monitoring);
— recording geometry and load variables and states of inputs and outputs into nonvolatile memory (datalogger);
— automatically blocking of crane mechanisms: hook lifting winch at uppermost (anti two-block system) and lowermost (last wirerope wrap) positions, luffing at stroke positions and etc.
— boundary and zone protection;
— automatically blocking of boom movements when AC field detector is on.
Thanks to standart interfaces, SBUC system can be added:
— GPS localization (with recording GPS coordinates in datalogger);
— GPRS data transmission;
— fuel management system;
— wind speed sensor.
