Types of Jack Hammer
yo rock drill
01

yO Serious Jack Hammer

1.Hand-held rock drill (handheld rock drill machine), mainly for handheld operation; small air legs can be added, but the design basis is handheld.

2.The body is short and the center of gravity is suitable for two-handed holding; the thrust is provided by manual hand pressure, and a small FT100 air leg can be selected as an auxiliary.

3.Light weight, the impact energy is relatively small, the air consumption is low, and the air compressor requirement is small.

4.Economic hole depth: 1.5–2m, limit: 5m, shallow hole efficiency is high; suitable for medium-hard rocks f=6–12; suitable for downward / inclined downward holes (slope, secondary dissolution of quarrying).

yT Serious Jack Hammer

1.Air leg rock drill (with FT air legs) relies on the air legs to provide continuous thrust, making it suitable for horizontal tunnel excavation.
2.The rear end of the machine is equipped with an air leg connection seat, and standard models include FT160 and other air legs. The air legs automatically provide continuous and stable axial thrust, eliminating the need for manual continuous pressure on the drill machine.
3.It has a greater self-weight, higher impact energy and rotational torque. It consumes more air and requires a larger displacement air compressor. It has stronger continuous hard rock excavation capability.
4.Economic hole depth: 2–4m, maximum 5m; medium-hard to hard rock; f = 8–18; It is proficient in horizontal, inclined and upward anchor bolt holes, and is better for deep hole slag removal and continuous advancement.

Stable and reliable

Core components are meticulously crafted, ensuring stable performance even under harsh conditions.

Maintenance is convenient.

The modular design is easy to disassemble and assemble, saving time and effort for daily maintenance.

Customized services

Support OEM/ODM, suitable for different engineering scenarios.

 

 

Jack Hammer & Air Compressor Matching
 

 

A pneumatic rock drill requires a stable compressed-air supply to maintain impact performance and drilling efficiency. When selecting a jack hammer, do not check air pressure alone. The compressor should also provide sufficient airflow for the selected model, together with allowance for hose length, pressure loss and other pneumatic equipment.

Before ordering, provide us with the jack hammer model, required drilling depth, hole diameter and available compressor specifications. Our team can help match the rock drill with a suitable air compressor and accessories.
