Huada Tracked Permanent Magnet Wire Saw DWS-75M-E

Product Positioning: A Rail-Free Wire Saw for Complex-Terrain Quarries

The biggest highlight of the DWS-75M-E is its tracked chassis. Traditional quarry wire saws need rails to be laid first and then move along them to cut; the tracked design can travel directly over uneven quarry ground, greatly reducing positioning time.

This model is especially suitable for open-pit mines with large terrain variations and frequently changing working faces. For mines that need frequent relocation or operate on muddy roads during rainy seasons, tracked machines are more mobile than rail-mounted ones.

Key Structure and Specs

The DWS-75M-E is equipped with a 75 kW permanent-magnet motor, the same as the DWS-75M, giving ample power reserve. Wire speed of 0–40 m/s covers common cutting speeds from soft to hard rock. The max cutting spacing of 1950 mm handles most small-to-medium blocks.

The track system uses dual-track synchronized drive combined with optimized programs to keep the machine stable during cutting. Compared with single-track or simple tracks, dual-track synchronization is less likely to slip or skew when turning or working on slopes.

The optional battery pack is a practical feature for short-distance relocation without external power, reducing cable dragging and connection time. Optional wireless remote control lets the operator manage the machine from a safer position.

Cutting Performance and Material Compatibility

The DWS-75M-E scores close to the DWS-37M/55M/75M series, with efficiency at 7.8 and material compatibility at 7.5. The 75 kW motor provides enough power for hard-rock cutting, but the tracked structure is slightly less stable than heavy rail-mounted equipment when facing extremely hard granite.

Wire-break control and accuracy score around 7.1, which is above average for Chinese quarry wire saws. For quarrying where output is the main goal, this is acceptable; if mirror-flat faces are required, additional measuring and guiding devices are needed.

The flexibility of tracked travel comes at some cost in positioning accuracy. For long straight cuts, use guiding devices or periodically correct track direction to ensure kerf straightness.

Who It Suits: Quarries with Complex Terrain and Frequent Relocation

The DWS-75M-E best suits open-pit stone quarries with complex terrain, dispersed working faces and frequent machine moves. Small-to-medium mines in the Middle East, India and Southeast Asia especially benefit from its mobility.

For mine owners who already own fixed wire saws and want a highly mobile auxiliary machine, the DWS-75M-E is also a good choice. It can flexibly fill in when the main machine is under maintenance or for special working faces.

If your quarry has flat ground, fixed working faces and very high long-term stability requirements, a traditional rail-mounted permanent-magnet wire saw or imported heavy-duty equipment may be more suitable. Tracked systems have higher maintenance complexity than rail systems.

Pre-Purchase Reminders

• Assess terrain suitability: although tracks are highly mobile, they can be limited on extremely soft ground, steep slopes or exposed rock; survey the site first.
• Confirm whether battery pack and wireless remote are needed: these options improve convenience but increase purchase and maintenance costs.
• Request a full specification: the official site does not publish total power, accuracy, axis count or recommended maintenance intervals, so confirm with the distributor.
