2012-2 EDITION MICHELIN SOLUTION EARTHMOVER and PUBLIC WORKS

Earthmover MICHELIN tyres are built to perform HIGH-TECH PRODUCT Machines that use earthmover tyres are involved in most economic activities. The machines are frequently used in difcult or even extreme conditions. Mines, ports, infrastructures, industry - these are all demanding environments which can really put tyres to the test! In response, Michelin is committed to developing ranges of tyres that are suitable for each type of machine and use. The tyres are divided into 8 families, and are constantly being updated to take account of developments in machines and their uses. Key gures Over...

Technology of MICHELIN radial casing tyres A tyre’s construction is the key to its performance, and outstanding tyre performance is a key competitive advantage for transport and working machines in the earthmover industry. Earthmoving equipment can achieve outstanding performance by using radial tyres. Composition The radial design combines metal or fabric plies, extending from one bead to the other, with a belt made of several steel plies designed to reinforce the crown of the tyre. A unique construction with numerous advantages The sidewalls and crown work independently: Minimizing the...

Comparison beetwen bias and radial tyres Bias or diagonal ply construction The casing is made up of several criss-crossed plies. The crown and sidewalls are formed by the same ply structure. The crown is not stabilized. The tread is affected by exing of the sidewalls, resulting in: ฀฀ eformation of the tyre contact area d on the ground ฀฀ ฀ ฀ ฀ ฀ ฀ The casing plies tend to “scissor” in relation to each other Disadvantages: ฀ ฀ ฀ ฀ ฀ ฀ ฀ The MICHELIN X radial The sidewall and tread function separately.

According to the standardized usage (ISO-ETRTO-TRA-JATMA*) The four main categories of earthmover tyre are dened by their use. The category to which it belongs is indicated on the sidewall of the tyre.

Particularly resistant to cuts, tread tearing and abrasion at average speeds which are higher than those for A4 (above). Compromise solution between abrasion resistance and average speed on rough surfaces. Higher resistance to internal heat generation on surfaces which are not particularly rough. Adapted to running on long cycles at high speeds on well-maintained roads. Very high resistance to high average speeds on long cycles run on well-maintained roads....
