The features of the Φ 700 manhole cover are as follows:
1. environmental protection is noise free. The product is environmentally friendly and noise free. The frame is processed by lathe, so that the frame is consistent.
2. high load capacity. This product has high load capacity and can bear the rolling of heavy objects.
3. strong anti-theft capability. The product adopts double anti-theft design, which has better anti-theft performance and can effectively ensure the safety of traffic road.
4. long service life. The anti-theft and noise protection settings of the products are firm and durable.
1. sound insulation, no noise, in accordance with environmental protection requirements. Each set of ductile iron covers are processed in three processes, which makes the contact surface between the cover and the ring zero, which makes the two fit seamlessly, eliminating the noise generated by vehicles.
2. it has strong falling resistance bearing capacity. During the test, the bearing capacity of the ductile iron manhole cover is not damaged under 500kN pressure, which is far better than the national standard. The requirements of en 124 are met at the same time. It can bear the rolling of various heavy trucks, and effectively prevent the fall of the manhole cover.
3. anti theft
The lock and key are made of high hardness and embroidered brass to prevent the lock from rusting during daily use and prevent the cover from being opened. The new five anti double layer ductile iron manhole cover adopts the integrated design of manhole cover and well ring, and the rotary installation lock national utility model.
4. noise resistance
No noise, in accordance with environmental requirements. Each set of products produced by our company has been processed in three processes, making the contact surface between the cover and the ring zero, so that the two can be seamlessly matched to eliminate the noise of vehicles passing through. In the design of the new five manhole cover, the new type of five manhole cover is adopted, so that the vehicle does not bump into the manhole cover when passing the cover, but it hits the edge of the well circle to prevent the cover from sinking as a whole, and effectively solves the "bad side" problem around the urban manhole cover.
5. fall prevention
The bearing capacity is strong. In the test, the bearing capacity of the manhole cover of ductile iron is 500kN, which is far better than the national standard (360kn). The requirements of en 124 are met at the same time. It can bear the rolling of various heavy trucks, and effectively prevent the fall of the manhole cover.
6. anti slip
The exquisite casting technology makes the product line clear, the surface of the manhole cover has anti-skid pattern, which increases friction, and prevents pedestrians from slipping due to rain and snow.
