Common failures & inspection points

Slew Bearing Degradation - tooth wear, raceway pitting, bolt looseness, and inadequate lubrication leading to compromised slewing accuracy and structural integr

Visual inspection for tooth wear and pitting; measure bolt elongation; perform grease sampling on large cranes; assess lubrication condition at specified intervals

Wire Rope Deterioration - broken wires, internal/external corrosion (accelerated in marine environment), diameter loss, and lubrication degradation affecting lo

Count broken wires per ISO 4309; measure rope diameter loss; inspect for external and internal corrosion; verify lubrication status; conduct magnetic testing for internal wire degradation

Load Hook Failure - cracks, deformation, wear exceeding 10% of original dimension, latch malfunction, and structural fatigue under cyclic loading

Visually inspect for cracks and deformation; measure wear at dangerous section (throat) against original dimensions; check safety latch engagement and clearance

Structural Boom/Frame Integrity - cracks, deformation, corrosion in main structural components (boom, pedestal, A-frame) reducing load-bearing capacity and safe

Visual inspection for cracks and deformation on boom and frame; assess corrosion extent; verify structural alignment and clearances; conduct non-destructive testing (NDT) on high-stress areas

Electrical/Hydraulic System Failures - fluid contamination, seal degradation, pressure loss, control system malfunction, and cable insulation breakdown compromi

Test hydraulic fluid for contamination and viscosity; inspect seals for degradation; verify system pressure and response; test electrical controls; inspect cable insulation and connections
