Product Description
"Using technology of frequency modulation"
Frequency modulation Tower-Crane is the result of applying digital on traditional tower crane technology. This has caught up advanced standard on the world. Frequency modulation tower crane was popularly used on all high building in Vietnam, China, Brunei, Singapore, Canada and so on.
Connected system of tower crane is controlled by frequency equipment. Gear-box are imported with stable and durable operation, minimum troubles of operation. All signals are sent to microprocessor, this microprocessor will control signals and logic process. And all structures are controlled automatically. Errors are forecasted automatically. Condition of operation is controlled by microprocessor equipment without switch. Control cabin is designed by special insulating glass for convenient space of cabin, wide scope of observing for operator.
