Tripping Out: Latching Elevators to Pipe
During the tripping-out process, the floor crew latches the elevators onto the drill pipe so the string can be safely lifted from the wellbore. Elevators are a critical hoisting component and must be properly aligned, closed, and secured before any load is taken.
This task is performed repeatedly during tripping operations and requires close coordination between the driller and the floor crew. Improper latching or poor hand placement can result in serious pinch-point or struck-by injuries.
Elevators Latched to Pipe – OSHA
Potential Hazards
- Hands or fingers being pinched or crushed in the elevator doors or latching mechanism.
- Being struck by elevators that are not fully or securely latched before the pipe is lifted.
- Hands or fingers getting caught between the elevators and the pipe stump or tool joint.
- Dropped or swinging elevators due to improper alignment or equipment failure.
Possible Solutions
- Ensure workers are properly trained in correct elevator latching procedures, including using elevator handles and keeping hands clear as elevators descend over the stump or tool joint.
- Visually confirm that elevators are fully closed and latched before signaling the driller to take weight.
- Inspect elevators, latches, hinges, and pins regularly and remove damaged or malfunctioning equipment from service.
- Maintain clear communication between the driller and floor crew during latching and hoisting operations.
