Pneumatic Pipeline Ramming Hammer with 250 t Impact Energy High-Energy Impact and Double-Lock Rear Anvil for Trenchless Drilling

Designed for trenchless installation of underground pipelines, the BH650 delivers 250 t (2,500 kN) of impact energy in a compact, air-driven package. Its simple mechanics, millimetre-grade steering accuracy and rapid advance rate make it the most cost-effective rescue tool for stalled HDD projects and the first-choice method for short-run casing installations.

• Double-Lock Rear Anvil (Patented): BAIWEI's signature clamping system generates 200% more grip force than any competitor, eliminating anvil slip and giving the industry's safest, most reliable connection.
• Integral Forward Wear Sleeve: A one-piece striker carries replaceable polymer wear rings that prevent metal-to-metal contact, maintaining full striking power over thousands of metres.
• Quick-Set Push Chuck: The tapered, self-locking chuck engages 152 mm (6 in.) into the steel casing for a rigid, frame-free joint. Set-up and breakout times are cut by half, while the smaller collar diameter reduces jacking-pit size and spoil removal.
• Field-Proven & Patent-Protected: Developed, cast and machined in our own facility, the BH650 has been in continuous production for more than ten years and is covered by multiple national patents. Every unit is dynamically balanced and impact-tested before shipment, ensuring the consistent quality that has made BAIWEI the reference brand for pneumatic rammers across four continents.
