DR CRANE LEAD SYSTEM The Dual Rotary Crane Lead System utilizes Foremost DR drill components installed and mounted onto crane leads. Drilling operations can be controlled from auxiliary hydraulics on the crane, or an independent hydraulic power unit (HPU). Intermediate lead sections can be added to the base section to increase the mast length. This makes it suitable for various lengths of single pass pile placement, thus increasing drilling productivity. The Dual Rotary Crane Lead system can be operated with a Hydraulic Spotter (this gives rigidity to the mast and acts as a torque arm) allowing pile placement within the radius of the crane. Another option available is an anchored template which acts in place of the torque arm and also acts as a casing guide. Both designs offer accurate pile placement in unstable drill sites. FEATURES Since acquiring the Dual Rotary technology from Barber Industries in 1993, Foremost has continually updated, refined and expanded the DR line with the goal of enhancing its functionality and extending its range of applications. Today, Foremost offers several DR models, each packed with features that deliver heightened safety, productivity, and profitability across a variety of drilling activities. CYCLONE COLLECTOR The optional cyclone sample collecting system slows discharge velocity to allow accurate and continuous sampling of the formation. DISCHARGE SWIVEL All drill cuttings rise to the surface between the drill pipe and casing, and exit through the discharge swivel attached to the top of the casing. The discharge swivel directs cuttings to a safe dumping point or to an optional cyclone collection system.
