Construction equipment
Tower crane-LNQS series lifting mechanism LNQS08/LNQS12
The LNQS series products adopt a modular design, consisting of variable frequency speed control motors NGW planetary reducer and drum assembly. The product has the characteristics of compact structure, low noise, and light weight, and is suitable for construction sites such as building construction and precise lifting.

1 NGW planetary reducer, all gears are processed with hard tooth surface grinding technology, and the accuracy is above level 6.
2. Adopting a large diameter double groove drum, the rope arrangement performance is good and the service life is long.
3. The motor adopts frequency conversion speed regulation technology, which runs smoothly and has low impact, and can achieve slow positioning near zero speed and precise lifting.
4. The frequency converter has complete protection functions, runs smoothly, and is safe and reliable.
5. Extremely low starting current and low energy consumption.
6. Suitable for construction sites such as building construction and precise lifting.
