Verify transport, lifting, and access heights before movement. See margins, warnings, and compliance decisions instantly. Reduce clearance risks across gates, bridges, and overhead services.
The page stays in a single vertical flow, while the form uses responsive multi-column fields.
These sample rows show how practical values can be prepared before performing a live check.
| Scenario | Measured Height (m) | Attachments (m) | Dynamic (m) | Surface (m) | Safety (m) | Sag (m) | Legal Limit (m) | Route Clearance (m) | Outcome |
|---|---|---|---|---|---|---|---|---|---|
| Flatbed with site generator | 3.70 | 0.18 | 0.05 | 0.03 | 0.20 | 0.05 | 4.50 | 4.45 | Pass |
| Excavator on trailer | 3.95 | 0.12 | 0.06 | 0.05 | 0.25 | 0.05 | 4.50 | 4.30 | Not compliant |
| Site cabin move | 3.55 | 0.08 | 0.04 | 0.02 | 0.20 | 0.04 | 4.20 | 4.05 | Pass with caution |
This approach separates regulatory restriction from physical route restriction. That helps planners identify whether the problem is legal, physical, or both.
It checks whether a vehicle, load, or equipment setup fits under both a legal height restriction and the actual route clearance after all added allowances.
Safety margin is an intentional planning buffer. It protects against measurement error, unexpected movement, poor visibility, and site deviations that may not appear in the base dimensions.
Legal limit is the maximum permitted height by rule or policy. Route clearance is the actual physical space available under a bridge, gate, beam, or cable.
Yes. Include all parts that can increase top height, even temporary ones such as hooks, beacon lights, protective frames, stacked pallets, or tied-down accessories.
Uneven ground, rutting, ramps, and slopes can tilt or lift one side of the load path. Surface variation captures that extra real-world height risk.
Yes. Choose the imperial option and enter every value in feet. The report still shows a metric internal basis for consistency and checking.
No. It supports planning, but approval may still depend on permits, escort rules, utility coordination, traffic control, and site-specific lifting procedures.
Projects often prefer more than 0.15 m of spare margin, and many teams demand much higher buffers. Always follow your method statement and local requirements.
This tool is best used during route review, temporary works checks, delivery planning, crane transport preparation, and site access assessment. Always verify critical clearances with current field measurements and project controls.
