Steel Masts


Logging Masts - Heavy Duty Steel


BenchMark Wireline is a market leader in the design and manufacture of logging masts. The company has been making logging masts since 1981. BenchMark Wireline manufactures both lightweight portable aluminum and heavy-duty steel lattice masts.

Features and Benefits

The heavy-duty steel lattice logging masts are most often used on offshore well sites. They are very strong and durable and are offered in heights of 75 and 90 feet.

Steel lattice masts offer several advantages. They have better high wind performance than solid masts. Any damage to the mast is easily observable and repairs to a lattice mast are often easier to make than solid mast designs. Corrosion protection is also applied to every surface.

The heavy-duty masts are normally fitted with a seven-ton winch, plus two additional two-ton winches. All are hydraulically operated and have automatically extending and manual extracting locking pins for safe scope-up and scope-down. All have fail-safe and anti-freefall technology, and hydraulic braking.

A lightweight 75 foot Heli-Portable steel fly-in mast is also available.

A Zone 1 or 2 approved electric or pneumatic power pack is available as well as a remote or safe-area diesel option.

Also a Zone 1 and 2 tension and depth measuring device with elbow is available.
