Alliance unveils a new approach to dual excavator tyres
At Reifen 2012, the Alliance Tire Group presented a new off-road tyre it says represents an innovative approach to dual-tyre configuration for excavators. Called the 528 Dual Master, the new product solves the problem of stones becoming embedded between double tyres. It does this through the use of a unique sidewall construction that enables close contact between the two tyres. “There is normally a rubber spacer between the tyres, but stones nevertheless get between the tyres and cause punctures,” commented ATG marketing communications manager Tal Rappoport to Tyres & Accessories. “The 528 Dual Master is the first tyre model for excavators that doesn’t require this spacer, and stones therefore can’t get penetrate this space.
Rappoport commented that ATG’s researchers strive to innovate, and this effort can be seen in products such as the 528 Dual Master. The radial, which is available in size 380/80R 22.5, is designed for longer tread life, comfortable ride, lower fuel consumption and an overall machine capacity increase. ATG says that a strong all-steel casing provides greater machine stability plus optimal puncture protection and retreadability.
