draw-works

The front drawworks guard should be put back in place when the operation is completed.

The floormen remove the front cover of the drawworks first.

Note: some drawworks are equipped with a fixed clamp on the side of the drum.

Then, the mechanical method is used for strength analysis of the drawworks to ensure the strength to meet security needs.

Remove the front guard cover of the drawworks.

Install the front drawworks guard cover after the mast is raised.

A clutched, rotating spool that enables the driller to use the drawworks motor to apply tension to a chain connected to the makeup tongs.

Hydraulic well testing drawworks includes mobile roller drawworks and fixed roller drawworks.

When all personnel are ready, the driller engages the drawworks in forward drive and starts reeving in the new drilling line.

Install newly cut fast line into the drawworks drum and fasten the clamp with the torque wrench.

Next, reeve the 1 inch manila rope through the fast line sheave and pull back to the drawworks drum.

Its performance directly affect the whole rig, thus the user pays special attention to the operation and reliability of the drawworks.

Cut the gusset off from the ODS drawworks skid, and weld back on square, production and QC issue.

The drawworks has passed factory tests and has been put into industrial put, and has well reaction.

The braking characteristic of the brake system of rig drawworks is a basis of design and use of brake apparatus .

The driller also operates the drawworks brake using a long-handled lever.

We lubricate rig (drawworks) very often.

Manually reeve 6 wraps of the 1 inch manila rope onto the drawworks drum.

Two floormen secure the fast line on one side of the drawworks.
