Which elevator type uses slips that engage with the casing to provide a secure hold by applying weight on the slips?

• A. Bail Type Elevators.
• B. Slip Type Elevators.
• C. Casing Elevators.
• D. Hydraulic Elevators.

Answer: (B)

The main idea here is the gripping mechanism that uses slips to bite into the casing when you put weight on them. In a slip-type elevator, wedge-shaped slips are inside the elevator body. When the elevator is closed and weight is applied, those slips are forced outward against the outer surface of the casing, and the teeth or serrations bite in to hold the pipe firmly. This provides a secure, clamp-like grip that keeps the string from slipping during lifting or lowering. Other elevator types use different ways to secure the load. Bail-type and casing elevators rely on other gripping arrangements rather than slips biting into the casing, and hydraulic elevators use hydraulic force to actuate grips rather than the weight-on-slips mechanism.
