Who should inspect and repair hydraulic leaks on a crane?

• A. The crane operator
• B. Maintenance intern
• C. Supervisor
• D. A qualified technician

Answer: (D)

Hydraulic leaks on a crane are a safety-critical issue that must be handled by trained professionals. Hydraulic systems operate under high pressure and use fluids that can cause serious injury if released improperly. A leak can signal worn seals, damaged hoses, or compromised fittings, and attempting to inspect or repair it without proper training can lead to sudden pressure release, fluid injection injuries, fires, or loss of crane control.

A qualified technician is the person equipped with the technical knowledge, manufacturer procedures, and the right tools to diagnose the source of the leak, safely isolate and depressurize the system, replace components as needed, and verify the repair. They also ensure that the repair is documented and that the system is tested to the correct specifications before returning the crane to service.

Others in the workplace, such as the operator, intern, or supervisor, may detect the problem or oversee work, but they do not have the required credentials or procedures to perform hydraulic inspections and repairs safely and correctly.
