Workover Masts
Compact workover masts for well intervention and maintenance operations.

Compact workover masts for well intervention and maintenance operations.
DSL offers a range of masts and substructures for workover and drilling rigs ranging from 150 to 500,000 lb hook-load capacity, in single or double-stand set-up. All are designed and manufactured to API 4F, of which DSL is a licensed manufacturer and designer.
Anchorless (internally guyed) masts eliminate the need to anchor the mast, reducing risk in your operations and cutting rig-up and rig-move costs. They can be incorporated into almost any existing truck-mounted or trailer rig, giving you a quick, qualified solution for replacing your mast and substructure.
