A Practical Drilling Solution for Restricted Construction Areas

When carrying out anchoring and drilling operations in basements, underground structures, and other confined spaces, equipment needs to combine a compact structure with flexible mobility. Limited entrance widths and low working heights can directly affect equipment access, positioning, mast setup, and subsequent drilling operations. For Basement Anchoring Drilling, equipment dimensions and flexibility are particularly important.

The Anman AM-3 is designed specifically for these types of working conditions. As a Low-Clearance Anchoring Drill Rig, it combines a narrow body, split-type design, telescopic feed frame, and independent crawler travel systems to provide a practical equipment solution for anchoring and drilling operations in restricted construction spaces. As a type of Confined-Space Drilling Equipment, the AM-3 can better adapt to different restricted construction environments.

Split-Type Design for Easy Equipment Positioning

Unlike conventional integrated drilling rigs, the AM-3 separates the main unit from the hydraulic power station. Both the main unit and power station are equipped with crawler travel systems and operating controls, allowing them to be moved separately when required.

When the construction area has narrow access routes or limited equipment entrances, this design provides more options for equipment arrangement. The main unit and power station do not always have to be moved as a single unit. They can enter the construction area separately according to the available space and then be positioned according to the drilling location. This provides greater flexibility for Basement Anchoring Drilling and other confined-space construction operations.

The AM-3 has an overall width of only 1.06 meters. Its narrow-body design allows it to pass through relatively narrow access routes and equipment entrances, making it more suitable for construction areas with strict equipment size requirements. For Confined-Space Drilling Equipment, a narrow body can reduce the space limitations encountered when entering the construction area.

Telescopic Feed Frame for Low-Clearance Construction

In basement and underground projects, working height is an important factor when selecting drilling equipment. The AM-3 uses a two-stage telescopic feed frame that can be retracted during transportation and when entering the construction area. For a Low-Clearance Anchoring Drill Rig, this design allows the equipment to better adapt to limited working heights.

Once inside the construction area, the feed frame can be extended according to the available working space. The feed frame has a maximum stroke of 2.65 meters, while both the maximum feed force and pullback force reach 40 kN. The maximum feed and pullback speeds can reach 26 m/min.

This design allows the equipment to adjust the feed frame within relatively limited working heights while maintaining a substantial drilling stroke. For construction projects with restricted headroom, the telescopic feed frame provides a more flexible configuration for mast setup and drilling operations. It also allows the AM-3 to be used as Confined-Space Drilling Equipment in more restricted construction environments.

Adjustable Clamping System for Different Drilling Requirements

Different anchoring projects may use different drill rods and drilling tools. To address this requirement, the AM-3 is equipped with a clamping system that supports switching between single-clamp and double-clamp configurations.

The clamping range is Φ45–Φ200 mm. The working stroke can also be adjusted by changing the limit blocks, providing additional adjustment options for different drilling operations.

This design allows the clamping configuration to be adjusted according to the drill rods, drilling tools, and construction methods used on the project rather than being limited to a single fixed clamping method. For Basement Anchoring Drilling, the adjustable clamping system can also be configured according to different drilling requirements.

Stable Structure During High-Stroke Drilling

When the feed frame is extended for drilling, overall equipment stability is an important factor in the machine design. The rear of the AM-3 main unit is equipped with a 350 kg cast-iron counterweight.

The main platform uses a solid structure to support the equipment and balance the weight distribution around the rotary head. The rear counterweight works together with the overall machine structure to provide a stable configuration during feed-frame extension and drilling operations.

In addition, both the AM-3 main unit and hydraulic power station use crawler undercarriages, allowing the equipment to be positioned and transferred within suitable construction areas. This configuration also allows this Low-Clearance Anchoring Drill Rig to adapt to more restricted construction environments.

Power for Anchoring and Drilling Operations

The AM-3 is equipped with a 93 kW engine. Its hydraulic system has a maximum pressure of 28 MPa and a maximum flow rate of 250 L/min, providing power for the machine's hydraulic functions.

The rotary head delivers a maximum torque of 11,800 N·m and a maximum rotational speed of 100 r/min. Both the maximum feed force and pullback force reach 40 kN.

These specifications provide the hydraulic and rotary power required for the machine's anchoring and drilling functions while maintaining a compact overall design. For Confined-Space Drilling Equipment, maintaining appropriate drilling power while keeping a compact structure is an important basis for practical construction operations.

What Applications Is the AM-3 Suitable For?

The AM-3 is particularly advantageous in anchoring projects where equipment dimensions and available working space need to be carefully considered. In Basement Anchoring Drilling, underground projects, foundation reinforcement, slope reinforcement, and other drilling operations in confined spaces, the AM-3 can demonstrate its advantages.

For example, if a contractor is looking for a compact anchoring drill rig suitable for basement construction, the AM-3 can be a suitable choice. Its narrow body and telescopic feed frame allow it to move through narrow entrances and operate in areas with limited working height.

Because the AM-3 adopts a split-type design and is equipped with crawler travel systems, it can be moved and positioned flexibly, allowing it to adapt to more complex construction environments.

For contractors looking for Confined-Space Drilling Equipment, the AM-3's split-type design, narrow body, and crawler travel systems provide more options for equipment access and positioning.

The AM-3 combines independent movement, adjustable clamping, a telescopic feed frame, and high-torque power into one equipment configuration, specifically designed for drilling operations in confined spaces. As a Low-Clearance Anchoring Drill Rig, these features allow it to meet the requirements of anchoring and drilling operations in restricted spaces.

A Compact Equipment Solution for Professional Drilling Operations

The design focus of the Anman AM-3 is clear: while maintaining anchoring and drilling capabilities, the equipment is designed to adapt to construction environments with limited working space.

With an overall width of 1.06 meters, a maximum feed-frame stroke of 2.65 meters, a 93 kW engine, and maximum torque of 11,800 N·m, the AM-3 provides a compact equipment configuration for Confined-Space Drilling Equipment applications.

The split-type design, two-stage telescopic feed frame, adjustable clamping system, crawler travel system, and rear counterweight together form the key structural features of the AM-3. These features are designed to meet the practical requirements of equipment access, positioning, mast setup, and drilling operations in restricted construction areas.

For Basement Anchoring Drilling, the AM-3's narrow body, split-type design, and telescopic feed frame allow the equipment to adapt to limited construction spaces. As a Low-Clearance Anchoring Drill Rig, the AM-3 combines independent movement, adjustable clamping, telescopic feed-frame adjustment, and high-torque power into one equipment configuration, providing a practical equipment solution for anchoring and drilling operations in restricted spaces.
