ND Type Wire Rope Electric Hoist

Autonomous and controllable design concept of core technology:

Cooperate with major university research institutes to develop core spare part, and can relize the independent production of core spare part, so as to achieve controllable product quality and controllable construction period.

1. Lifting drive Unit

2. Travelling drive unit

3. Security monitor

Autonomous and controllable of core spare part:

[1]Reducer

• Structure Design of Reducer

• 8 Kinds of Driving Devices

• ventilation and heat dissipation design

Intelligent safety monitoring system has the advantage as follows:

• Calculating the remaining safety cycle of lifting mechanism

• Brake safety operation times

• Accumulated starts times of hoisting and travelling

• Records the load tonnage

• Overload protection, prohibit users from illegal overloading operations

• Real-time monitoring of crane' s operating Power Supply

• Motor overheat protection

• Extensible wireless access point, it can access to user's big data centet monitoring management, so as to realize remote operation and maintenance

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

Rugged and safe design concept
