Drilling Rig Components Drilling Equipment Drawworks API Standard
Product description:
The drawworks is the core component of the drilling rig, and is mainly used for feeding drilling tools, raising and lowering masts, tripping and
unloading drill pipes, and running casings.
Designed and manufactured to API Spec 4F standards.
Design features of mechanical winches:
A: All bearings are roller bearings. The shaft of the winch is made of alloy steel.
B: Forced lubricated chains are used, with high transmission precision and high strength.
C: The winch drum has grooves. Ventilated air clutches make up the high and low ends.
D: Forced cooling of the brake drum (brake disc) with circulating water.
E: The surface of the winch is treated by intermediate frequency quenching, which is durable.
F: The sprocket tooth profile is treated by intermediate frequency quenching.
