Product Description

Source brand NWH series of wire rope hoist, compact structure, stable operation, precise position.Germany imported from efficient lifting and running mechanism to ensure each electric hoist good performance, safe and reliable.Frequency conversion control, braking energy feedback and security monitoring system makes the source of the application of new technologies such as card wire rope electric hoist is always at the forefront of the industry.
Lifting mechanism
Lifting motor, reducer, drum, and the ceiling position switch integrated compact design saves the user's use of space.Modular design in enhanced the reliability of the institutions at the same time effectively reduce the maintenance time and cost.
The design of lifting mechanism strictly enforce FEM related standards.
Technical features:
 aluminum alloy reducer shell
 stable operation, low noise
 lifelong lubrication (safe use cycle)
 double disc electromagnetic brake disc
Lifting motor
Standard hoisting motor to double someone who comported himself (another frequency lifting motor for the user to choose), all motor adopts a cylindrical rotor.The standard for IP55 protection grade of the motor insulation class is F.Motor shell composed of aluminum alloy control, good heat dissipation performance, hoisting motor end install a fan to enhance the cooling effect.All lifting motor winding is embedded with the thermistor (or thermal switch) in order to prevent the possibility of motor overheating.Norwich companies use the thermistor VDE0631 standard (or thermal switch).
In front of the motor assembly, stator winding should be 100% of the strict test, the test contents and methods in accordance with DIN EN60204-1 (VDE0113) related standards, specific include:
 and resistance
 pulse voltage inductance value
 insulation between the winding and ground conditions
 winding resistance
Good motor assembly based on VDE0530 standard for high voltage test: test duration is 1 second)
Test voltage U = U (2 x rated voltage + 1000 v) 1.2 x
For frequency lifting motor can be mounted to the encoder, the encoder usually installed directly on the motor fan shaft end.
Technical features:
 small starting current, torque
 soft start, speed performance is good
 design service life is long
 technical parameters with FEM and HMI standards
 high speed, low noise
Lifting gear reducer
Reducer shell using aluminum alloy material, light weight, corrosion resistance.Fully half of grease lubricant sealed box to make all the gear can get sufficient lubrication, the use of safety in the design cycle without change of lubricating oil.
Every after surface hardening and high precision grinding processing gear reducer smoothly running.
Technical features:
 small volume, light weight
 stable operation, low noise
 corrosion protection, maintenance free
Lifting brake
Norwich, hoisting machine is equipped with double disc electromagnetic brake disc.Brake integration, at the end of the motor when the motor power brake automatically closed, to prevent slip load.Brake the brake clearance after the first set of manual adjustment (clearance can be adjusted by the brake spring itself), when the brake lining thickness is lower than the set value through additional control switch can automatically alarm, prompting the user for replacement.Safe and reliable in Norwich double disc electromagnetic brake disc, brake number up to 1 million, in the use of safety period without maintenance.
According to safety norms, Norwich companies choose the brake of the brake torque is not less than 1.8 times the rated torque.
Technical features:
 fast and high reliability
 maintenance free, since the adjustment
 dustproof design, long service life
Drum, wire rope, the rope guide
Drum made from high quality seamless steel tube by CNC machine tool processing and become, after finishing the rope on the drum groove with guide line which can effectively prevent slack rope and disorderly rope.
Wire rope using the tensile strength of 2160 N / ㎡ imported high strength steel wire rope, good safety, long service life.
Standard guide line with high resistance to wear and lubricating good engineering plastics processing and become, which greatly reduces the security components which is a major force of wire rope wear, thereby enhancing the safety of the hoisting mechanism.At the same time, according to different usage, Norwich, the company also provides the nodular cast iron production and manufacturing of heavy guidance on the rope.
The car run institutions
Many years of experience in Norwich company car running mechanism can adapt to different work environment, such as voltage instability condition even worse.Frequency conversion car running mechanism is the standard configuration in Norwich wire rope hoist, frequency control of motor speed greatly reduces the lifting weights in the shaking in the process of operation, enhances the safety of operation, at the same time reduces the operating cycle time, improve the production efficiency.
According to different conditions, the company offers two solutions:
Standard running motor overheating protection and electromagnetic disc brake.At the same time, we also provide single speed and a two-speed trolley traveling mechanism for users to choose.
Hoisting height limiter
Imported from Germany are free to adjust the screw type hoisting height limiter high accuracy, the adjusting range is extensive.Multi-touch configuration can effectively realize the rising and falling fast, slow and stop switch function.
Technical features:
 the adjusting range is extensive, high precision
 reliable quality, long service life

NovoStar safety monitor

NovoStar is Norwich company developed exclusively for NWH series wire rope electric hoist safety monitor unit, it can be realized according to the requirement of the user a variety of functions:
 calculate the rest of the work safety hoist
 hoisting working time
 the cumulative number of overload
 hoisting motor start times
 hoisting motor overheating protection and alarm
 overload protection and alarm
 brake lining thickness report to the police
 display fault information and maintenance tips
NovoStar and Norwich company special lifting and running frequency converter can realize real-time communications, through effective Settings, NovoStar control center can truly become a gourd.
