Crane Lifting Mechanism Electric Wire Rope Hoist Low Headroom Hoist NHA Series

Rope Guider

Use special high-strength Nylon which light weight, good wear resistance, Prevent wire rope from
skipping and loosing to off-groove, and safety first.

Hook

Forge high-strength alloy steel T grade hook, DIN standard with safety clasp and wire rope
sheath ergonomic design.

Contorl Panel

Top brand electrical unit and inverter for long service life.
Clear labeling and socket design for easy maintenance and wiring.
Multiple protection devices to make sure the safety.

Advantages:

1. Low headroom design, compact, strong, long service life span, save your space.
2. Three-in-one lifting motor: AMB Germany original imported. Column rotor, low noise.
3. Limit Switch: Cam limit model operate safety.
4. With load limiter protection.
5. Remote control avaliable.

New advantages:

1. Improved travelling motor: Lower noise, more effciency
2. Improved wire rope guider: Improved to engineering plastic material, lighter, less wear to wire rope

1. Reducer
Third-class dead axel helica gear transmission structure is adopted,; gear and gear axel are made of heat treated alloy steel.
2. Control Box
It has device with up an down stroke protection of break off limiter and can cut off main circuit in an emergency,which ensures safe operation of electric block.Electric elements are of long service life and operational safety.
3. Steel Wire Rope
It uses GB1102-74(6*37+1) hoist steel wire rope which is durable in use.
4. Conical Motor
The hoist motor uses conical motors of relatively stronger starting torque to brake asynchronous motor and does not need extra arrester. The motor s load duration factor is 25%.
5. Button Switch
Its hand-operated, easy to handle,and has two modes of cord operation and cordless remote control
6. Gear
By adopting Japanese technology, they are innovated symmetrical arrayed high-speed synchronous gears, and are made from international standard gear steel.
7. Chain
Adopts high strength chain and high precision welding technology,meet ISO3077-1984 international standard;fits for gusty overload work conditions;takes your hands a better feeling multi-angle operation.
8. Hook
Made of high-class alloy steel,it has high strength and high security; by using new design, weight will never escape.

Description of configuration:

1. Power 380V-50HZ-3P control voltage:48V

2. Lifting reducer and Motor

3. Electrical Unit: Schneider

4. Wire rope: high strength wire rope with zinc surfacing

5. Traveling Gear Motor: motor, controlled by Yaskawa/Schneider inverter

Application
Used in the factory, mine, dock, warehouse, temperature-20 ~ + 40 °C, relative humidity under 85%.

Design Feature
(1) imported motor can be chosen for high working level up to M5, low noise
(2) applies to factories, freight yards, terminals, power plants, construction sites and other places
(3) Particularly suitable for the plant with restrict height, maximize the effective lifting height

Detailed Product Description

Low Headroom Electric Wire Rope Hoist is the newly developed type which is specific to the box type beam but not the traditional I beam. You can benefit from shock absorption and noise reduction. What's more, the distance for the gauge can be adjusted. This products, by its newly unique design and great originality, have gained a good reputation among users in China and abroad.
