Product Description

What is TOP DRIVE SYSTEM(TDS)

DQ30BQ-VSP top drive features

Dimensions of your drill derrick:

The top drive system (TDS): a revolutionary drilling technology that utilizes a suspended motor, either electric or hydraulic, to deliver the essential torque for rotating the drill string. By replacing the conventional rotary table and kelly drive methods, this system ushers in a new era of enhanced drilling efficiency, reduced manual labor, and elevated safety standards.

It is mainly composite of Main Motor and Air Cooling System, Brake System, Gear Box, Gooseneck Assembly, Rotating Head Assembly, Tilt System, Counterbalance System, Back Up Tong Assembly, Pipe handller, hyadraulic system, guide rail, electrical control house, driller console and service loop....

1.Folding guide Rails: Top drive installation is safe, quick and convenient.

2.Equipped with 360° swivel head rotation function.

3. The pulley adopts a double-wheel structure to avoid single force on the roller and extend the service life of the roller.

4. IBOP Rack and Pinion Drive Mechanism: Ensures precise and accurate switching of IBOP (Internal Blow Off Preventer).

5. Inclined hanging backup tong: Replacing tong teeth and tong teeth seat becomes faster and more convenient.

6.Hydraulic Radiator: Extends the life of the hydraulic system.

7. The internal counterbalance is adopted: which makes the jump safe and stable. No other components are needed to hang the big hook or the traveling carriage, and it can be hung directly.

8.The cross-sectional size of the top drive is small: and it is more suitable for derricks.

Please specify the following dimensions and related information of the derrick.  (kindly give the editable drawings  as much as possible):

1,What is the effective height of the derrick?  (the distance from the drilling platform to the bottom of the crown block) , the type of derrick, the name of manufacturer,  the height from the monkey board to the drilling platform? What is the safe height allowed of the derrick? The type of mud hose union (top drive end).  The span between two sides of the derrick part of the drilling platform. 

2,Please provide drawings of the bottom of the crown block, with detailed dimensions marked. 

4,What is the length of a single drill pipe?  How many drill pipes form a drill stand?
