Summary
A crane hydraulic hose snagged on a protruding grease fitting during outer-jib retraction. Incorrect hose routing and insufficient pre-use inspection were identified, with potential for hose rupture, crane failure and an oil spill. The Master stopped operations, the hose was corrected, and pre-use inspections and checks for similar snagging were recommended.

Summary
While retracting the outer jib of the boom during crane operations, one of the hydraulic hoses caught on the protruding grease fitting of the boom bearings, which could have led to a failure of the crane and hydraulic oil spill due to hose rupture.
