NR Electric Hoist Features:

1. Without reverse rollers/wheels;

2. Bilateral drive, the reducer directly drives the wheels;

3. The hoisting mechanism is more convenient and quick to connect, also available for the trolley structure;

4. Capacity 3t, 5t hoist lifting mechanism is with fully closed structure, the other capacity hoist is with open gear drive;

5. Dual drive for capacity 32t~80t variable frequency hoisting mechanism;

6. Capacity 3t~16t lifting mechanism is with C-type structure, while capacity 20t~80t lifting mechanism is with Z-shaped structure.

Lifting Gear Motor Features:

1. Lifting motor is a gear motor, the front cover of the motor is connected with the reducer, and motor shaft head drives the gears;

2. The motor case is stretched aluminum (6063), and the reducer case cover is cast aluminum alloy (ADC12);

3. Motor performance: S3-40%, Class F IP54, 2/12 pole dual speed, 4 pole frequency conversion;

4. Reducer: Hard tooth surface, 20CrMnTiH;

5. Brake: Electromagnetic disc brake.

Traveling Gear Motor Features:

1. Coaxial structure;

2. Traveling motor is a gear motor, the front cover of the motor is connected with the reducer, and motor shaft head drives the gears;

3. The reducer is an output spline shaft structure with flanged connection;

4. The motor case is made from stretched aluminum (6063), reducer case covers are made from cast aluminum alloy (ADC12) or cast iron (HT250);

5. Trolley and hoist share the same running;

6. Motor performance: S3-40%, Class F IP54, 4 pole frequency conversion;

7. Reducer: Hard tooth surface, 20CrMnTiH;

8. Brake: Electromagnetic disc brake.

Components Features:

1. Reel/Drum: Finished steel pipe (with ring gear for 10t above capacity hoists);

2. Wire Rope: 1960~2160 grade wire rope;

3. Hook Block: New hook set with beautiful appearance;

4. Fixed Pulley: MC nylon pulley, pulley shaft is overload sensor;

5. Rope Guide: Nylon rope guide;

6. Rope wedge: Standard wedge;

7. Wheel Group: Internal spline structure (without the torque support of the reducer), ductile iron.

Structure Features:

1. The hoist frame consists of plates and rods;

2. Assembly after painting, high-strength bolt connection;

3. Flange plate bending structure on both sides of the reel;

4. Small structure rotation limit, flange connection;

5. Lifting and hoist frame with pin connection.

6. Lifting structures is the same with the trolley type;

7. Use a large number of rectangular tube structures;

8. The driving wheel is with an internal spline structure, and the driven wheel is similar to a monorail wheel structure.

NR Electric Hoist Advantages:

1. Modular and universal:

6 kinds of punching and base

10 motor power

4 lifting gear reducers

4 kinds of running reducers

7 wheel sets

2. Core components are produced independently, with controllable core technologies:

Guaranteed Quality

Guaranteed Delivery

Non-standard design

3. Full range of NR electric hoist adopts large diameter reels with less left and right limit;

4. A new safety monitoring system with functions of overload protection, Information statistics and inquiry, fault inquiry, collaborative work of 2 hoists, etc.

5. Internet of Things (IOT) cloud connection: Through the security monitor and the (tree root) IoT module communication, the cloud platform storage and remote monitoring of the NR hoist data is realized.
