PRODUCT INFORMATION TOP DRIVE DRILLING SYSTEM Canrig Drilling Technology Ltd. 14703 FM 1488 Magnolia, TX 77354 Main Office: 281-259-8887 Main Fax: 281-259-8158 Email: [email protected] Web: www.canrig.com Canrig Drilling Technology Ltd offers a complete range of electric Top Drive models with hoisting capacity from 275 to 750 tons. In our DC units the horsepower for each model increases as the hoisting capacity is increased. The gear ratio for each model can be altered to provide varied torque to speed ratios. Canrig’s AC top drives range in hoisting capacity from 500 to 750 tons. The use of AC technology produces improved performance resulting in a “fatter” torque curve. A brief description of our models is as follows:

PRODUCT INFORMATION AC TOP DRIVE MODELS AC Technology Since the advantages of using top drives are well documented, the decision for most operators is whether to use DC or AC technology. Both have advantages that warrant consideration depending on application. The primary benefit of AC top drives is a significant better power factor. AC motors also have a better speed range and can be run at 200% of base speed and above. The horsepower characteristics of an AC motor are far superior to the DC equivalent. DC motors can maintain maximum horsepower at only one speed while AC motors maintain fill horsepower from base speed to approximately 150% of base speed. Other advantages to our AC Top Drive Drilling Systems are: • • • •

• •

Can stall motor for an indefinite period, with zero to maximum torque applied. Enclosed, EExe or TEFC motor possible. This would eliminate the blower hose (a rather cumbersome, but necessary feature on the DC motor). Less maintenance due to lack of brushes. With a TEFC motor, this becomes double important, considering that no dirt or moisture will be entering the motor and its windings. By utilizing a 12 pulse front-end variable frequency drive, substantial reduction in harmonics to the point where it will meet and exceed requirements of IEEE 581 standards, can be achieved. This feature becomes valuable if drilling power is obtained from Hiline Utility distribution. Our innovative modular design of the drive also allows for plug and play repair and maintenance. New technology. Utilization of latest components and engineering knowhow.
