Ro-Ro Ramp SWL, Axle Load & Ramp Gradient Tool
Screen whether a truck, trailer, MAFI, heavy plant or project vehicle can negotiate a ship ramp. Compare total concurrent ramp load, axle/group loads and wheel contact loads against approved limits, calculate ramp angle and gradient, check approach/breakover geometry, estimate uphill traction demand and identify the loading constraint before operations begin.

Advanced Vehicle / Loading Sequence Register
Each row is checked independently for gross ramp load, axle/group load, wheel contact, geometry and traction. Concurrent count drives the total ramp SWL check.

Ramp Certification & Operational Readiness
Structural limitation: This tool does not calculate ramp plating, stiffener, hinge, cylinder, wire, bearing or supporting-hull strength. For abnormal loads, obtain the ship/class/structural approval required by the vessel's procedures.
