HammerHead Trenchless Equipment, a Charles Machine Works company, has introduced the new HammerHead Roughneck R200, the first two-inch rock hammer engineered specifically for horizontal directional drilling applications. The R200, the smallest pneumatic rock hammer of HammerHead’s Roughneck line, is designed to expand the capabilities of small utility drills allowing 7,000- to 10,000-ton class directional drills to effectively drill through solid rock as well as other difficult soil conditions.
The R200 rock hammer was made to be the most efficient system available to HDD contractors in communications, gas, electrical and water service installations. The R200 model drills a 3.125-inch pilot hole.
A key feature unique to the R200 rock hammer is the electronically-controlled air flow. With the touch of a button the operator can adjust the air flow from open to closed and anywhere in between which allows management of the power of the hammer on the fly. This feature is designed for situations where soil conditions change abruptly. The ability to reduce or increase power quickly is designed to prevent costly interruptions during the bore.
The HammerHead R200 air hammer shares similar features with the other models of the HammerHead Roughneck line. The Roughneck R400, R500 and R600 pneumatic rock hammers are designed for HDD applications. All four models are capable of drilling at rates of up to 150-feet per hour with exceptional steering performance. Additionally, all Roughneck rock hammers feature side-load high-flow housing, a patented pull back kit system and a lightweight control station.
Serviceability is a key design feature in all HammerHead pneumatic hammers and the R200 is no exception. Spanner wrench holes in the front and rear of the hammer are designed to reduce the number of breakout jaws required when performing maintenance or changing out rock bits.
The HammerHead R200 rock hammer is offered as a complete system to get contractors up and running. The system includes a R200 Roughneck air hammer, offset and angled offset bits, patented pullback kit, control station/oiler with tethered electronic remote control, hydraulic breakout tooling, 2.5-inch universal high-flow housing, and a conversion kit specific to the drill.
