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.
