20t 9m Crane Lifting Electric Wire Rope Hoist for Double-Rail Crab

NL Type Wire Rope Electric Hoist:A new generation Electric Hoist which fabricated according to ISO,GB,FEM,DIN,BS standards1. Autonomous and Controllable Design Concept of Core TechnologyCooperate with major university research institutes to develop core spare part, and can realize the independent production of core spare part, so as to achieve controllable product quality and controllable construction period.Autonomous and controllable of core spare part:- Motor (Structural Design and Electromagnetic Calculation of Motor):a) Electromagnetic Designb) Bearing Life Calculationc) Force Analysis of Spindled) Ventilation and heat dissipation design- Reducer (Structure Design of Reducer):a) 8 Kinds of Driving Devicesb) Light Alloy Shellc) Low Carbon Alloy Forged Steel, Grinding Technologyd) High quality seals, heavy duty industrial gear oil- ASW Anti-swing system (The Third Generation Anti-Swing Control System):a) Function upgrade: It can replace PLC to realize logic control and electric anti-swing functionb) High Matching: No Restriction on inverter brandc) Cost advantage: Saving communication cards and lines- Integrated controller:a) Fault Information Displayb) Voltage and Current Protectionc) Overload protection functiond) Travelling record Functione) Logic Control Functionf) Real-time monitoring functiong) Anti-swing functionh)Anti skewed and inclined liftingi) Big Data Communication- Frequency:a) For crane use only: It owns the features as follows: small volume, small power and high cost performanceb) High support performance: It can support open-loop vector control and V/F control, the starting torque is largec) Special Control Function: Equipped with special brake control function of crane driving systemd) Wide range of applications: It can be widely used in driving and controlling occasions such as the lifting, translation and rotation of lifting equipmentIndependent Production of Core Components Advantages:a) Quality Assuranceb) Customized Designc) Fabrication Time Guaranteed) After-sales Guarantee2. Modular design conceptNR Electric Hoist with modular structure can fully meet your requirements which owns unprecedented flexibility and can provide you with perfect solutions for personalized needs.Modular Design:a) Motor Moduleb) Reducer Modulec) Drum Group Moduled) Wheel Group Module3. Intelligent and remote operation and maintenance design conceptIntelligent safety monitoring system has the advantage as follows:a) Calculating the remaining safety cycle of lifting mechanismb) Brake safety operation timec) Accumulated starts times of hoisting and travellingd) Records the load tonnagee) Overload protection, prohibit users from illegal overloading operationsf) Real-time monitoring of crane's operating Power Supplyg) Motor overheat protectionh) Extensible wireless access point, it can access to user's big data center monitoring management, so as to realize remote operation and maintenanceA new generation of security monitoring system:a) More accurate recording of system information: timing and counting can be accurate to seconds, and real-time queries can also be realizedb) Black Box Function which can record the malfunctions and operationsc) More comprehensive monitoring: it can monitor peripheral equipment and power supply situationd) Multi-channel monitoring signal access: crane condition, fault category diagnosise) Instant Messaging Function which owns the features as follows: convenient networking and remote information transmissionf) More comprehensive output such as: operation output, fault output, timely alarmingg) Operating Interface: Both in Chinese-English Language, Real-time Clock4. Low headroom and compact design conceptAll 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.a) Larger diameter drumb) Larger winding rope capacityc) Higher lifting heightComparison of the length of Traditional and New Type Electric Hoist with the same lifting height, NR Type Electric Hoist5. Design concept of Maintenance-free, energy-saving and GreenIntegral structure of Gear motor: Compact structure/Reduce the deadweight/Reduce noisea) The motor power is reduced by 30% compared with the traditional Electric Hoistb) Through the mature application of Variable frequency positioning technology, the work efficiency is improved by more than 20%c) The noise of the whole machine is below 70 decibelsd) The brake pads adopt non-asbestos designe) No metal dust caused by the slide friction between the Nylon Rope Guide and Steel Wire Rope, drum, providing workers with high cleanness operation environmentf) 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 productg) Adopt international brand and mai
