Shenli highlights heavy-duty air pick hammers for mining and tunneling

Shenli Machinery Trading Co., Ltd. is pitching its Air Pick Hammer line for mining, tunneling and rock-breaking jobs that face continuous impact, vibration and wet underground conditions. The company says the TPB40/TPB60/TPB90 series is built to reduce wear, improve air efficiency and support safer field use.

Why it matters: - Mining and tunneling crews need breakers that can handle repeated shock, dust, water and long shifts without losing output. - Tool failure can slow production, raise maintenance costs and increase safety risks underground. - Shenli is positioning its air hammer products as a heavy-duty option for projects that need durable pneumatic equipment and stable performance across difficult geology.

What happened: - Shenli Machinery Trading Co., Ltd. published a product announcement from Langfang, China, on June 29, 2026. - The company promoted its Air Pick Hammer line for deep underground extraction, tunnel construction, heavy rock fragmentation and open-pit mining. - Shenli directed customers to its enterprise website for technical specifications and custom order inquiries.

The details: - Shenli says its Air Pick Hammer body parts use monoblock forging with premium alloy steel. - The company says atmosphere-controlled quench furnaces create a hardened outer skin rated at HRC 58-62 while preserving a tougher inner core. - Shenli uses a four-bolt mechanical fastening system on the back head to hold the air valve and cylinder in alignment. - The company says extra-deep threads on the air inlet are designed to reduce pressure leaks in wet, muddy mine conditions. - Shenli says the grip area uses shock-absorbing material and an easy-access safety trigger switch to help reduce hand-arm vibration. - The TPB40, TPB60 and TPB90 Air Pick Hammer series is presented as a benchmark for rock clearing, pavement breaking and block-holing work. - The TPB90 model specifications listed by Shenli include a 66.67 mm piston diameter, a 152 mm stroke and 1,400 blows per minute. - The TPB90 weighs 42 kg and measures 723 mm in overall length. - The TPB90 air consumption rate is listed at 2.2 m³/min at standard operating pressures. - The TPB90 uses a 3/4 P/T air inlet connection, requires a 19 mm internal hose diameter and is compatible with Hexagonal 1-1/8 by 6 inches or R32*152 mm shank and bit heads.

Between the lines: - The product pitch centers on durability, air efficiency and reduced vibration rather than just raw breaking force. - Shenli is also signaling that lifecycle support matters, including model selection, secure export packing, on-site setup and wear-part availability. - The emphasis on technical specs suggests the company is targeting buyers who compare tools on measurable performance data.

What's next: - Shenli says it is available to discuss direct technical specifications and custom orders through its support desk. - The company appears to be using the announcement to attract mining and construction buyers looking for replacement or procurement options for heavy-duty pneumatic breakers. - Further adoption will likely depend on how the tools perform in field conditions and whether after-sales support matches the product claims.

The bottom line: - Shenli is marketing its air hammer range as a rugged, specification-driven option for harsh mining and tunneling environments.
