• Drawworks positive gears all adopt roller chain transmission and negative ones adopt gear transmission.
• Driving chains with high accuracy and high strength are forced lubricated.
• The drum body is grooved. The low-speed and high-speed ends of drum are equipped with ventilating air tube clutch.
The main brake adopts belt brake or hydraulic disc brake, while the auxiliary brake adopts configured electromagnetic eddy current brake(water or air cooled).

The drilling Swivel is the main equipment for the rotary circulation of the underground operation. It is the connection between the hoisting system and the drilling tool, and the connection part between the circulation system and the rotating system. The upper part of the Swivel is hung on the hookblock through the elevator link, and is connected to the drilling hose by the gooseneck tube. The lower part is connected with the drill pipe and the downhole drilling tool...
1. The hook block adopt the integrated design. The traveling block and the hook are connected by the intermediate bearing body, and the big hook and the cruiser can be separately repaired.
2. The inner and outer springs of the bearing body are reversed in opposite directions, which overcomes the torsion force of a single spring during compression or stretching.
3. The overall size is small, the structure is compact, and the combined length is shortened, which is suit...
Technical Features:
• The sheave grooves are quenched to resist wear and extend its service life.
• The kick-back post and rope guard board prevent the wire rope from jumping out or falling out of the sheave grooves.
• Equipped with safety chain anti-collision device.
• Equipped with a gin pole for repairing the sheave block.
• Sand sheaves and auxiliary sheave blocks are provided in accordance with users’ requirements.
•The crown sheaves are completely interchangeab...
• 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 step...
