Modular Design:
Motor Module
Reducer Module
Drum Group Module
Wheel Group Module
Intelligent and remote operation and maintenance design concept
Intelligent safety monitoring system has the advantage as follows:
Calculating the remaining safety cycle of lifting mechanism
Brake safety operation time
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 center 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
Low headroom and compact design concept
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.
Larger diameter drum
Larger winding rope capacity
Higher lifting height
Comparison of the length of Traditional and New Type Electric Hoist with the same lifting height, NR Type Electric Hoist
Design concept of Maintenance-free, energy-saving and Green
Integral structure of Gear motor: Compact structure/Reduce the deadweight/Reduce noise
The motor power is reduced by 30% compared with the traditional Electric Hoist
Through the mature application of Variable frequency positioning technology, the work efficiency is improved by more than 20%
The noise of the whole machine is below 70 decibels
The brake pads adopt non-asbestos design
No metal dust caused by the slide friction between the Nylon Rope Guide and Steel Wire Rope, drum, providing workers with high cleanness operation environment
The high-precision hard gear reducer has been filled with international brand lubricants before delivery from factory , and there is no need to replace it within the service cycle of the product
Adopt international brand and maintenance-free steel wire rope
High-strength Nylon rope guides, change from wearing parts to durable parts
International brand electrical components, bearings, and pendent controller
Electromagnetic disk brake with automatic compensation of brake clearance and maintenance-free function
Rugged and safe design concept
The whole machine passed the national standard life test (1600 hours)
The service life of electrical components is not less than 500,000 times
The safe use of brake reaching 1 million times
The breaking force of the wire rope reaching grade 2160
The hook adopts high-strength T-class hook head
10 years free maintenance of speed reducer
