The Challenge
Previously, the company relied on manual cutting methods using hand-pushed machines. These required constant water cooling to prevent blade overheating, and the blades were frequently damaged. The result was high operational costs and very low productivity.
Project Overview
The customer specializes in the construction of new roads in
Xinjiang, a region in northwest China known for extreme seasonal temperature fluctuations. These variations cause the roadbed to expand and contract, leading to cracks in the asphalt. This compromises traffic
safety and allows water infiltration, accelerating pavement deterioration.
The Solution
To address this issue, the
SIMEX RWE 35 wheel saw is used to cut
5 cm-wide grooves at 100-meter intervals along the roadbed. These grooves act as expansion joints, allowing controlled movement of the road surface due to thermal variations. This prevents surface cracking and significantly improves pavement
durability. Mounted on an XCMG XE 80D 8-ton excavator, the RWE 35 achieves a
cutting speed of 2 meter per minute—more than five times faster than the previous manual method.
Productivity improvements have been accompanied by a substantial
reduction in costs for consumable parts.
The RWE 35 is equipped with the
tilting self-leveling system: thanks to the articulated support that rotates on the axis of the drum, the slides always rest stably on the ground, granting a
constant trenching depth in any condition. The particular design of the outlets and the trench clearing device with manual-mechanical insertion guarantee the correct expulsion of the milled material, leaving the
trench cleared at the set depth.
The RWE 35 wheel saw is an
extremely versatile attachment, designed both for mounting on 8-13 tons
excavators and
skid steer and
compact loaders, with the addition of the hydraulic side shift, thus taking the name of RW 350.
