What is an elevator drilling rig?

But deep in the world of drilling rigs, elevators are doing some heavy lifting of their own — only they’re not carrying people. They’re gripping tons of steel pipe, moving them with precision, and playing a starring role in well construction. Meet elevator drilling equipment — the unsung workhorses of the rig floor. What Is an Elevator in Drilling?

What is elevator drilling equipment?

Meet elevator drilling equipment — the unsung workhorses of the rig floor. What Is an Elevator in Drilling? In drilling, an elevator is a mechanical device designed to latch onto and lift drill pipe, casing, or tubing during the process of running them into or pulling them out of the wellbore.

What are the different types of drilling elevators?

There are many types of drilling elevators, each suited to different pipe sizes and functions: Side-door elevators swing open like a gate, allowing pipe to be inserted horizontally. Slip-type elevators grip the pipe using friction and are typically used for smaller diameter strings.

How do Elevators work on a rig?

Suspended from the rig’s hoisting system, elevators are attached to the top drive or hook and operated by rig crew members. They may look like simple clamps, but these devices must support weights exceeding hundreds of tons — safely, repeatedly, and quickly.

What is the difference between a slip elevator and a casing elevator?

Slip-type elevators grip the pipe using friction and are typically used for smaller diameter strings. Casing elevators are heavy-duty and designed to handle large-diameter, heavy casing during well construction.
