3) AC Variable Frequency Drive Drawworks

Technical Features :

The main components of drawworks are AC variable frequency motor, gear reducer, hydraulic disc brake, winch frame, drum shaft assembly and automatic driller etc, with high gear transmission efficiency.

The gear is thin oil lubricated.

Drawwork is of single drum shaft structure and the drum is grooved. Compared with similar drawworks, it is of many merits, such as simple structure, small volume and light weight.

It’s AC variable frequency motor drive and stepless speed regulation in whole course, with high power and wide speed adjustable range.

The main brake adopts hydraulic disc brake, and the brake disc is water or air cooled.

The auxiliary brake is of motor dynamic braking.

Equipped with independent motor automatic drilling system.
