Manufacturer: Continental Emsco
Model: C3 (Type II)
Application: Drilling rig hoisting system for oil & gas operations.
Maximum Input Power: ~3,000 HP (rated for heavy drilling operations)
Typical Drive Configuration:
Can be configured with DC traction motors (e.g., three ~1,000 HP DC motors) for electric rigs.
On some rigs, powered by two electric motors (example: GE 752) with a Baylor 7838 electric brake.
Brake System: Typically equipped with large drum/brake assembly (often with auxiliary electric or mechanical brake systems).
Typical Weight: ~38 tons (weight can vary per configuration).
Control: Integration with rig drawworks control system for speed and torque regulation (exact systems vary by rig). (Not always listed in sales listings)
Exact torque, line pull, line speed, drum dimensions, and gearbox ratios depend on specific build/rig integration and are typically obtained from OEM manuals or rig-specific tech sheets.
Typical features for rigs using C3 drawworks include:
High line pull and torque capacity suited for deep drilling.
Multiple motor drive options (e.g., electric or diesel-electric layouts depending on rig design).
Land and offshore drilling rigs with hookload and line-pull demands well above lower-capacity models.
