Geotechnical drilling with a CME 55 is one of the most popular rental drill rigs today. Geotechnical investigations to analyze soil structure and substructure are most efficiently and successfully facilitated when conducted through the use of a CME 55 drill. While a truck-mounted drill is perfect for investigating most For commercial construction and in facilitating new building foundations, the CME 55 crawler-mounted drills are often more practical when investigating soil structure in more rural locations, for example in bridge and elevator engineering. In this article, I will discuss the features and capabilities of the CME 55 drill.
To list some of the main reasons why the CME 55 drill is so successful is that it has a lot of power, versatility and is reliable. For these reasons, this popular type of drill can easily handle geotechnical and environmental work very efficiently. It has been popular in its field for approximately 35 years and its high resale value is a testament to its performance in the drilling field.
This drill, as mentioned above, can be mounted on a variety of vehicles, such as two-wheel or all-wheel drive trucks, whether they have a single or tandem axle. As for its feed system, the hydraulic feed that is also a retract system allows for 28,275 pounds of retract force and 18,650 pounds of down pressure. There are no stretchable chains or cables in the hydraulic vertical drive system to reduce issues with the 72-inch stroke of this powerful drive system. It also allows precise aiming of drilling tools when applying force. Drilling clearance with the CME 55 in the vertical position is up to 10 1/4 inches of hollow bit.
As for the rotary transmission, this robust mechanical transmission provides 7,700 pounds of torque and speeds up to 800 rpm. This is possible because the four-speed transmission is connected to the engine through a strong 13-inch clutch. This drill has four forward gears and one reverse gear. As you can tell from these numbers, the CME 55 has the rotational speed and torque capacity for just about any situation. Thanks to these features and capabilities, drillers operating this machine get a good idea of the drilling conditions inside the wells and can detect when it is time to change feed pressure and torque rotation.
To further assist drillers and increase their productivity, the CME 55 drill’s controls are logically arranged at the driller’s station. For example, the most frequently used functions: the forward, lift and slide base levers are staggered for easy operation. Also, for safety reasons, there is a lock position for the clutch lever that is designed to prevent accidents.
