GDS Series

Features

Drillmec gear driven drawworks (GD Series) are the primary hoisting machinery used to raise and lower the traveling blocks. They consist of the following main parts: the drum, the motors, the reduction gear, the brake, and the auxiliary brake.

With the Massarenti experience and a unique aim for continuous improvement over decades of innovation, Drillmec produces a wide range of drawworks engineered for today’s tough challenges. As with other Drillmec drilling equipment, our drawworks can be fitted to all land rigs with power ranging from 1,500 to 3,000 hp with a nominal depth range of 3,500 to 10,000 meters (11,000 ft to 32,000 ft).

Main features:

• Lightweight design: our drawworks provide an exclusive design due to optimization of materials and a deep stress analysis study. The gear box transmission with helical gear enables a substantial noise and vibration reduction.

• Customized solutions: with more than 100 years of experience, our line of drawworks can be fully customized creating innovative proposals to add real value to satisfy customer needs. Among many custom solutions our drawworks can be equipped with a braking system with air-operated spring set disc brake (failsafe) or hydraulic caliper disc brake.

 

• Condition monitoring system ready: our drawworks are designed to install a condition monitoring system in order to maximize performance and save time. High performance digital hardware combined with dedicated monitoring technologies ensure control of deteriorating status of critical assets, delivering clear and precise condition information.

• Advanced digitalization: while development and application of automation technologies is a reflection of our historical pursuit of safety and performance, DEEP (Drillmec’s Embedded Efficiency Platform) has brought our products to the next step. The integration with the HMI allows to control repetitive drilling operations through various control systems such as the autodriller, the anticollision system and many more in ProRig and ProDriller.
