Slewing ring flange industry application scenarios

In the wind power yaw pitch system, the failure rate can be reduced by 30%. It is used in the military radar rotating platform and can adapt to (-45℃~120℃) extreme temperatures.

Or used on the rotary platform of engineering machinery excavators, Longan's flange torque density increased by 40%

Five core advantages of Longan flange

1. Ultra-low maintenance cost. Customers' actual test data show that the maintenance cost during the flange cycle is reduced by 25%, which is highly recognized by customers

2. Load capacity Static load: up to 1,800 kN·m

Dynamic load: continuous working load 450 kN·m @ 5 rpm

After slewing ring flange were used in Shanghai port cranes, customers had no structural failure feedback for 9 years

3. Installation efficiency increased by 45%, through product integrated design: reducing the number of docking parts, installation time is shortened to 2 hours, which is nearly half the time compared with traditional methods.

4. Super dustproof design sealing structure: triple lip seal ring, dust intrusion rate reduced by 90% (actual test data)

5. Life data: Under 15 tons of axial load, L10 life exceeds 100,000 hours (compared with the industry average of 65,000 hours), which is more than 50% longer than peers.
