API 7K Drilling Rig Components Drawworks JC50DB Carbon Steel

Drilling Rig Components API 7K Drilling Rig Drawworks JC50DB

Feature:

The design and manufacture of the drawworks conform to API Spec 7K and SY/T 5532, the drawworks standard for oil drilling rigs; the drawworks

series are complete sets, with single drum or double drum, and multi-shaft structure driven by mechanical or electric power; between the main brake

and the auxiliary brake Arranged to meet the requirements of power transmission and drilling/workover operations. The winch adopts the integrated

control of hydraulic system, pneumatic system and electrical system, which is easy to operate; the gear box of the electric drive winch adopts the

forced lubrication gear with large modulus hard tooth surface; the winch and its power unit can be installed on a sliding rail, which is convenient for

transportation ;
