Abnormal load haulage cost: what actually sets the price
Updated
Ask three hauliers for a price per mile on an abnormal load and you will get three polite refusals. Here is what they are actually costing, and how to give them enough to quote firmly rather than defensively.
Why per-mile pricing does not exist here
A standard freight movement is priced on distance and time because the route is a given. On an abnormal load the route is the variable: the structures that will accept the load, the roads that will take the width, the hours the authorities will allow, and how many working days of notice must be served before any of it can happen. Two identical machines going 80 miles can differ by a wide margin because one crosses an assessed structure and the other has to go around it.
What a haulier needs before they can quote firmly
- Four numbers. Length, width, height and weight, and honesty about which of them is an estimate. Height is the one most often wrong, and it is the one that meets bridges.
- Centre of gravity and lifting points, where the machine has them. This decides how it sits on the trailer, which decides the height.
- Both ends of the job. Hard standing, gradients, gateway widths, overhead lines and whether a crane can set up.
- Whether it can be driven or tracked on and off, or whether it must be lifted.
- Your date flexibility. Lead time is the cheapest concession a customer can make on this kind of work.
The questions that make quotes comparable
- Does the price include notifications to police, highway and bridge authorities, and any permit application?
- Is a route survey included, and is the quoted price based on the assessed route or the direct one?
- How many escort vehicles are priced, and what happens if the requirement changes after the route is assessed?
- What is assumed about loading and unloading, including standing time if the site is not ready?
- What happens if the movement window changes to nights or weekends at the authority's request?
- What insurance is carried for the load in transit, and what the limit is. Ask the question and read the answer; this site does not give insurance advice and cannot tell you what cover you need.
Where budgets get broken
- A dimension that was wrong. Everything downstream is built on the four numbers, and correcting one late can mean re-notifying.
- Access at the delivery end. The road move is the planned part; the last 200 metres onto the site is where the day is lost.
- Standing time. A crane, an escort crew and a tractor unit waiting for a site to be ready is the most expensive way to spend an afternoon.
- Short notice. Notification periods are in working days and cannot be bought out, so a compressed programme limits options rather than simply costing more.
For a straightforward plant or machine move that is not oversize or overweight, the notification machinery on this site does not apply and a general heavy haulage operator is the right call. Use the form and describe the load honestly; if it is not abnormal, the hauliers quoting will say so.
