Angle drilling system for special applications†
The CME-45C drill has a permanently coupled mechanical drive line which enables our unique angle drilling system. It is useful when drilling under ponds, storage tanks or other structures, but more commonly used for vertical borings on a slope. This eliminates the time consuming and costly job of leveling an area for the rig.
Automatic SPT hammer†
The CME-140 pound (63.5 kg) automatic hammer gives you extremely consistent and accurate Standard Penetration Test results, meeting all ASTM-D-1586 requirements. There are no ropes or cables to impede the 30 inch 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 effortless. For maximum safety, all moving parts are enclosed, including the impact area between the weight and the anvil.
Slide bases make the job easier and quicker
Both in-out and sideways slide bases are available for movement of the drill. A 15 inch (38 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. An 8 inch (20 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.
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.
