45C Features | 45C Specifications | 45C Optional Equipment
A 12,000 pound capacity winch is mounted on the front of the steel skid for the CME-45C rig. The winch is used for moving the rig on and off of the trailer as needed. Front and rear roller guides are included to facilitate the process. With the skid rig off the trailer, the front winch is used to maneuver the drill to the boring site. A two-speed hydraulic motor provides winch line speed of up to 40 feet per minute for quick spooling.
Automatic SPT hammer†
Our 140 pound (63.5 kg) automatic hammer gives you extremely consistent and accurate Standard Penetration Test results, meeting all ASTM-D-1586 requirements. Thats because there are no ropes or cables to impede the free fall of the weight. The hammer swings from stored position to on-hole position. Since raising and lowering is done hydraulically, set up is quick and almost effortless. For maximum safety, all moving parts are enclosed, including the impact area between the weight and the anvil. A 340/140 pound (154/63.5 kg) hammer is also available.
Slide bases make the job easier and quicker
Slide base options are available in both in-out and sideways movement of the drill on the platform. A 15 inch (38.1 cm) in-out movement allows you to quickly move the drill on and off the borehole and align the sheaves for lifting tools with the cathead or any of the hoists. A 8 inch (20.3 cm) sideways movement gives you even more versatility. Aligning augers or rods when making connections is easy. If the bit drifts off at an angle when you start a hole, you can quickly straighten it to a vertical position. Since the upright and optional mast are mounted directly to the drill frame, they move with the drill when the slide base is used. That means you can drill in any position within a 170 square inch (1097 cm²) area without moving the carrier. If you have ever tried to line up your rig on an existing bore hole, you’ve probably already recognized another benefit of the slide base.
Angle drilling system for special applications†
This unique system allows you to drill holes at various angles between horizontal and vertical. It is especially effective for drilling under ponds, storage tanks or other structures. When used with our patented Continuous Sample Tube System, you can even take soil sample while drilling angle holes.
Cone Penetrometer Testing (CPT)
CPT controls allow you to easily switch from typical geotechnical drilling and sampling procedures to pushing a cone. A dedicated hydraulic circuit including detented CPT control lever, hydraulic down feed pressure and CPT feed rate controls provide precise pressure and penetration adjustments required to meet ASTM standards. A separate CPT system hydraulic pressure gauge is provided as well. Anchor points are installed below the drill feed frame so that maximum available pressure can be applied to the CPT tools. A 12-volt power source can be provided at the drill control panel to accommodate electronic devices associated with CPT procedures. Mounting for depth transducers or other related equipment can also be provided.
