Technical Features:
• The Traveling Block is an important key equipment in the workover operation. Its main function is to form a pulley block by the sheaves of the Traveling Block and the mast , double the pulling force of the drilling rope, and bear all the downhole drill pipe or oil pipe and workover instruments through the hook.
• The sheave grooves are quenched to resist wear and extend their service life.
• The sheaves and bearings are interchangeable with th...
Technical Features:
• The transmission of rotary table adopts spiral bevel gears which have strong bearing capacity, smooth operation and long service life.
• The shell of rotary table uses cast-weld structure with good rigidity and high precision.
• The gears and bearings adopt reliable splash lubrication.
• The barrel type structure of the input shaft is easy to repair and replace.

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...
• 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...
• Designing and manufacturing conform to API Spec 8C standard and SY/T5035 relevant technical standards etc.;
• Select high-class alloy steel die to forge molding;
• Intensity check uses finite element analysis and electrical measuring method stress test. There are one-arm elevator link and two-arm elevator link;
Adopt two-stage shot blasting surface strengthening technology.
