Core Components

Rotary Table

The rotary table is a critical part of the drilling rig, slowing down bevel gear pairs to provide specific speed and torque for drilling tools. Features include spiral bevel gear drive for higher loading capacity and smooth operation.

Meets API 7K requirements
Spiral bevel gear for long service life
Casting and welding structure for high rigidity
Splash lubrication for gears and bearings

Drawworks

The primary hoisting mechanism for the rig, functioning as a large winch to raise or lower the drill stem. Shafts are made of high-strength alloy steel with rolling bearings.

Pressure lubricated high-accuracy chains
Water-cooled brake rim for extended life
Ventilating air clutch for drum shaft ends
Auxiliary eddy current brake options

F-Series Mud Pumps

API Spec 7K standard products with interchangeable fluid end parts. Designed for high pump pressure and large displacement requirements in demanding oil fields.

Compact structure with reliable performance
Longer stroke for improved water supply
Advanced suction pulsation damper
Available in F-500 to F-1600 models
