Structural Design and Electromagnetic Calculation of Motor

Structure Design of Reducer

A new generation of security monitoring system:

★ More accurate recording of system information: timing and counting can be accurate to seconds, and real time queries can also be realized

★ Black Box Function which can record the malfunctions and operations

★ More comprehensive monitoring: it can monitor peripheral equipment and power supply situation

★ Multi-channel monitoring signal access: crane condition, fault category diagnosis

★ Instant Messaging Function which owns the features as follows: convenient networking and remote information transmission

★ More comprehensive output such as: operation output, fault output, timely alarming

★ Operating Interface: Both in Chinese-English Language, Real-time Clock

Low headroom and compact design concep

All series Electric Hoist are equipped with large diameter drum, which can effectively increase the lifting height and reduce the left and right limits. Crane's dead zone when working becomes smaller, which can provide larger using space for the customers.
