NHD PM series

NHD-050PM-1/NHD-100PM-1/NHD-200PM-2

1.Motor and Brake

1).Permanent magnetic brushless motor has feature of compact size, high efficiency and low power consumption.
2).IP55 TEFC motor, class F insulation, good thermal performance.
3).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.
4).Total enclosed construction, withstands harsh conditions like those found in chemical, and electroplating environments.
5).Asbestos-free brake to meet international request.
6).Unique innovation PM motor with dedicated drive controller. Low starting current, not exceed 150% rated, energy efficient.
7).With built-in heat detector, when motor's inside working temperature reaches 140(±5)°C, the protection mechanism will trigger, and not allow lifting the load. Instead, it permits coming down to release the load.

2.Load Sheave

5 pockets on the load sheave ensures positive chain link seating resulting in smoother lifting.

3.Mechanical Brake and Overload Limit Clutch System

1).2 in 1 design, have the dual function of mechanical brake and overload protection system is good and it prevents the burn-out problem with some high frequency operations of much inching to precise and gentle load positioning which involves many pendant control / contactor / electric brake coil activations.

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

3).Friction Clutch prevents damage from overloading.

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

1).Intelligent phase error relay protection device. When the power is supplied, the controller can automatically work, the hoist can go up and down normally regardless the phase..

2).Over-heat and over-current protection functions.

3).Intelligent overload speed regulation, hoist can reduce speed working at 125% overload setting till trigger the over-current protection then the hoist stops.

4).Intelligent safety start system, after confirming the electronic control and motor are normally, then the hoist be on.

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° rotated.

8.Pendant Control

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

NHD-200PM-1/NHD-250PM-1/NHD-300PM-2/NHD-500PM-2

1.Gear Limit Switch

1).Use for NHD-200PM-1, 300PM-2, 500PM-2 three items.

2).Multiple 4 steps adjustment designed. It has practically limitless applications in regulating hoist operation to prevent potential incidents. It can precisely control stopping point at any positions in lifting range.

3).Patents：

• Taiwan patent no. M466909
• German patent no. Nr. 20 2014 006 109.2
• Japan patent no. 3193570
• China patent no. ZL 2014 2 0395985.8
• United States patent no.US 9263201

2.Motor Assembly

High precision and rugged motor housing is made of aluminum extruded alloy. Motor coil can be disassembled easily when need to repair.

3.Load Sheave & Chain Regulator

Easy to disassemble and re-assemble,convenient for maintenance.
