Key Features

 

Model : NHD-025-1/NHD-050-2/NHD-050-1/NHD-100-2/NHD-100-1/NHD-200-2

1. Motor and Brake

   1) IP55 TEFC motor, class F insulation, good thermal performance.

   2) DC motor brake:with two-side single disk brake, 

       electromagnetic brake actuates synchronously in the event of power failure to ensure the operation safety while 

       loading.

   3) Total enclosed construction, withstands harsh conditions like those found in chemical, and electroplating environments.

   4) Asbestos-free brake to meet international request.

   

   Over-Heat Protection

    With built-in heat detector, when motor’s inside working temperature reaches 140(±5)℃, the protection mechanism 

    will trigger, and not allow lifting the load. Instead, it permits coming down to release the load.

 

2. Chain Sprocket

    5-pocket chain sprocket for load chain smooth operation.

 

3. Mechanical Brake and Overload Protection

   1) 2 in 1 design, have the dual function of mechanical brake and overload protections.

   2) Mechanical brake collocate motor brake which provides fast braking function.

   3) Friction Clutch prevent damage from overload.

   4) Easily adjusted by the gear box outside Overload setting.

   5) Ensure operation safety and product life time.

 

4. Limit Switch

    Upper and lower gear limit switches are fitted to switch off the power simultaneously in the case of over lifting or 

    lowering position.

 

5. Control Panel

    Phase Error Relay

    Phase Protection, in case of any phase missing or incorrect, the hoist will not be in active, ensuring the safety 

    and durability to all components.

 

6. Load Chain

    Grade 80 hardened and galvanized alloy steel chain, endures harsh conditions such as rain, saltwater and chemicals 

    with minimal wear.

 

7. Hook

   1) Hot forged from high tensile steel.

   2) 360 degree rotation.

 

8. Pendant Control

    High protection grade IP65, fully water-proof, insulated, and impact resistant.

 

9. Robust Housing

   1) Fabricated of aluminum die-casting, durable and light weight.

   2) Matt-black powder coating finish for low visibility.

   Motor Ass’y

    Light and artistic motor housing is made of aluminum extruded alloy and motor coil can simply disassemble and repair.

 

2. Chain Sprocket and Regulator

    Can rapidly remove and replace unlike previous model have to remove motor or other components first.

 

3. Mechanical Brake and Overload Protection

   1) 2 in 1 design, have the dual function of mechanical brake and overload protections.

   2) Mechanical brake collocate motor brake which provides fast braking function.

   3) Friction Clutch prevent damage from overload.

   4) Easily adjusted by the gear box outside Overload setting.

   5) Ensure operation safety and product life time.

 

4. Gear Limit Switch

    Can precisely control stopping point at any position.

 

5. Control Panel

    Phase Error Relay

    Phase Protection, in case of any phase missing or incorrect, the hoist will not be in active, ensuring the safety 

    and durability to all components.

The purpose of Slider Kit is to gather common slideshow-like jQuery functionalities (such as news sliders, photos galleries/sliders, carousels, tabs menus)

When tracking mouse movement, you usually need to know the actual position of the mouse pointer. The event object that is passed to the handler contains some information about the mouse coordinates.
