The Φ700 manhole cover has the following points:
1. Environmental protection and no noise. This product is environmentally friendly and noiseless. The board and frame are processed by lathes, so that the board and frame can be 100% consistent.
2. High load capacity. This product has a load of 360KN, 600kn, 900kn, and a variety of load-bearing products.
3. Strong anti-theft ability. The product adopts dual anti-theft design, with better anti-theft performance, which can effectively ensure the safety of traffic and roads.
4. long lasting. The product's anti-theft and anti-noise settings are firm and durable.
1. Anti-noise and no noise, in line with environmental protection requirements. Each set of ductile iron manhole covers has been processed through three procedures to make the contact surface between the manhole cover and the well circle zero, so that the two can be 100% seamlessly consistent, and noise is generated when vehicles pass by.
2. Strong fall-proof bearing capacity. During the experiment, the ductile iron manhole cover bearing 500KN pressure was not damaged, and the bearing capacity was much better than the domestic standard. At the same time, it meets the requirements of EU EN124 standard. It can withstand the rolling of various heavy trucks and prevent accidents caused by the falling of the manhole cover.
3, anti-theft
Using a new design of anti-theft, the lock and key are made of high-hardness, embroidered brass to prevent the lock from rusting during daily use and make the manhole cover unable to open. The new five-proof double-layer ductile iron manhole cover adopts the design of the manhole cover and the well ring body, and the rotary installation lock has been obtained
family utility model benefit.
4. Soundproof
No noise, in line with environmental protection requirements. Our company's ductile iron manhole covers and each set of cast iron manhole covers have been processed through three procedures to make the contact surface between the manhole cover and the well circle zero, so that the two can be 100% seamless and consistent, preventing noise when passing by. In the new five-proof manhole cover design, the new
The -shaped design concept makes the vehicle not hit the manhole cover but hit the edge of the well circle once when passing through the manhole cover, preventing the manhole cover from sinking as a whole and solving the problem of “rotten edges” around the manhole cover in the city.
5, fall prevention
Strong carrying capacity. During the experiment, the ductile iron manhole cover bearing 500KN pressure was not damaged. The technical requirement of the cast iron manhole cover is much better than the domestic standard (360KN). At the same time, it meets the requirements of EU EN124 standard. It can withstand the rolling of various heavy trucks and prevent accidents caused by the falling of the manhole cover.
6, non-slip
The exquisite casting process makes the product lines clear. The anti-skid pattern on the surface of the manhole cover increases friction and prevents pedestrians from slipping due to rain, snow, and ice.
