Replacement Masts
Drop-in replacement masts to upgrade or replace existing drilling rig masts.

Drop-in replacement masts to upgrade or replace existing drilling rig masts.
DSL has designed a unique new range of drilling masts for 250–500,000 lb hook-load capacity carrier, trailer, workover and drilling rigs. The masts are fully interchangeable across a wide range of existing rigs, giving drilling contractors a simple solution should a mast be damaged or otherwise put out of service.
Capacities are held in stock to enable a fast response to customer requirements, and our engineering has implemented weight reductions where possible — for instance, the 500,000 lb mast can also serve a 400,000 lb application without modifying existing raising and scoping cylinders.
We support drilling contractors and operators with a full range of services including rig upgrades, refurbishment, inspection and recertification from our worldwide locations. The masts fit a wide range of workover and drilling rigs including Ideco, Skytop Brewster, Cabot, Stewart & Stevenson, Cooper, Franks, Cardwell and Kremco.
