Common failures & inspection points
Structural inspection of ramp deck plate and web frames for cracks, corrosion, and weld integrity, particularly at hinge and pivot points
Hydraulic system check: hoses, cylinders, seals, and fluid level/condition; test full deployment and retraction cycle for correct pressure and speed
Hinge pins, knuckle joints, and bearing bushings: lubrication, wear measurement, and corrosion treatment per OEM schedule
Ramp securing and locking devices (dogs, latches, hydraulic locks): function test in stowed and deployed positions; verify positive engagement
Sealing arrangements (rubber seals, compression strips) on stern door/ramp interface: inspect for wear, cracking, and watertightness under sea-state conditions
Slewing/swinging mechanism (where fitted): check drive units, limit switches, end stops, and alignment with deck guides
Anti-slip surfaces and edge protection on ramp deck: inspect for wear, damage, and compliance with load-class markings
Electrical and control system: verify interlock logic, emergency stop functions, remote/local control operation, and corrosion protection on connectors and junction boxes
