Established in 2004, Nagaoka Machinery is a leading manufacturer of elevator traction machines. Its main products include elevator traction machines, elevator parts, fireproof & smoke shielding products and a hybrid power system for ships. These products have been widely used in well-known companies domestically and globally. Currently, it is the largest elevator traction machines manufacturer in Taiwan, with an annual output of more than 7,000 units and has a market share of more than 45% in Taiwan. Besides, it has been well received for many years and has become one of the leading brands of customized elevator traction machines, and commissioned to manufacture by large domestic and foreign elevator manufacturers. Besides, we export machines to many countries such as Vietnam, Indonesia, Japan, China, Southeast Asia, Europe, Central and South America and so on. In addition, we designed the first set of 60B&120B fireproof and smoke shielding roller shutters in the country and became a leading brand of fireproof and smoke shielding roller shutters in the industry.

1. Fireproof and smoke shielding products:
a. 60B & 120B fireproof and smoke shielding roller shutter
b. Smoke shielding roller curtain
We design the first set of 60B&120B fireproof and smoke shielding roller shutters in the country and become a leading brand in the industry. The following are features of fireproof and smoke shielding roller shutters:
(1) Simple structure: Using imported high-efficiency fireproof & smoke shielding cloth. The structure is simple but safe and effective, and the installation and maintenance are also very simple and easy.
(2) DC power: We use a DC motor to drive fireproof and smoke shielding shutters; therefore, it can be utilized by batteries even if there is electricity block out or power cut.
(3) Intelligent design: It’s linked with the fire alarm system; therefore, when a fire occurs, the roller shutter will automatically lower to isolate the fire source and dense smoke and increase the escape time.
(4) Patent: Currently it has obtained new patents from Taiwan, Japan and China. The quality and technology are unique in the industry.

2. Traction machines
a. Gear Traction Machines: The worm gear design is the traditional model, and helical gear design is an improved version that is more efficient and has a longer product life compared to the worm gear type.
b. PM Traction Machines: In response to the market strong demand, Nagaoka launched the gearless PM traction machines with excellent characteristics such as 1. compact size 2. high operation safety 3. high efficiency 4. no fuel consumption and low pollution 5. machine runs smoothly with low noise & small vibration and 6. it’s the most suitable for machine room-less use.
c. Compound Traction Machines: Because of the market's strong demand for replacing the old gear traction machines with new ones, Nagaoka developed a new type of compound traction machine, the PMG series which is PM motor + helical gear. This series of products are suitable for all kinds of elevators and it’s the best choice for replacing the old traction machines with new ones under the roping 1:1. Besides, the series of products have the advantages of improving gear type efficiency, energy-saving, compact size and low replacement cost, etc. Besides, compared with traditional worm gear models, helical gears are more efficient.
