Electric Permanent-Magnet Crane
Targeting the features of marine crane, Just Marine have cooperated with several world leading firms with our own patented technology, and initially apply the hoisting technology of Control-Drive-Permanent-Magnet Motor integration into marine crane, and enable the ZJM crane to achieve the revolution breakthrough in safty, energy saving, reliability, which have been tested in practical applications.
hoisting capacity :14t—80t
JIB Radius:10m—41m
Hoisting Speed:15-50 m/min
Feature:
Short response times
Maximum speed based on actual load
Overload protection with load cell as standard open brake
Environmentally friendly
No hydraulic oil (ordinary hydraulic crane approx 700 litres)
30-35% less power consumption
30-35% lower energy (oil) consumption
higher efficiency under motor low load working condition
Low starting currency, low motor basic rpm,high transmission efficiency
Low noise level
Safety
Quick emergency stop from fully speed action, stable brake,low impact, expend the equipment lifespan
Regenerative electric power braking and mechanical braking double protection during power off, better security.
Intelligent and integration design, user can obtain the realtime crane working and safty condition
Minimum required space on deck and convenient for maintenance and repair
Diagnostic check during the whole performance, forecasting function.
Intelligent safe border system, hook point visualization system(Alternative option)
Intelligent system fully take advantage of the achievements in modern electrics, computer, Sensor Monitoring Technology, with the digitalized intelligent control and monitoring system as platform, combining the internet, wireless transmission and crane modern control system into a intelligent integration control system, which have the function of sensation, analysis,inference control and management. High integration, high modularizaion, high technology.
