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 ;
