AM-3

This low-headroom anchoring drill rig features a split design with a separate main unit and power station, both equipped with independent crawler tracks for flexible relocation.
With an overall width of only 1.06 m and a retracted feed frame height of less than 3 m, it can easily access confined spaces such as basements.
The two-stage telescopic feed frame provides a maximum stroke of 2.65 m. Combined with single/double clamp switching and a 350 kg counterweight, it enables low-headroom mast setup and long-stroke drilling for stable and efficient operations.

• •Split Design: Both the main unit and power station are equipped with crawler tracks and operating handles, allowing flexible relocation.
• •Two-Stage Feed Frame: The telescopic two-stage feed frame can easily pass through doorways and enter basements. During operation, it can be extended stage by stage according to the available space, with a maximum stroke of 2.65 m, enabling “low-headroom mast setup and long-stroke drilling.”
• •Single/Double Clamp Switching with Adjustable Stroke: Supports both single-clamp and double-clamp modes. By removing the limit block, the drilling stroke can be increased by more than 100 mm. The clamping range is Φ45–Φ200 mm, accommodating various drill rods. Different pipe diameters can be handled by changing the orifice plate.
• •Exceptional Confined-Space Adaptability: With an overall width of only 1.06 m, the rig can pass through standard doorways. With the feed frame retracted, it can complete mast setup, drilling, and relocation in basements with a floor height of only 3 m.
• •Enhanced Counterweight for Stable Operation: A 350 kg cast-iron counterweight is added to the rear, while the main platform features a solid structure. This effectively balances the weight of the front powerhead, prevents the center of gravity from shifting forward after mast erection, and ensures excellent stability during long-stroke drilling.
