What to Include in a Custom Special-Purpose Vehicle Enquiry

Describe the job, crew, road conditions and fixed requirements when enquiring about a custom special-purpose vehicle. Includes an example first enquiry.

What to Include in a Custom Special-Purpose Vehicle Enquiry

You can start discussing a custom vehicle while the chassis, layout and equipment list are still open. A useful first enquiry tells us what the vehicle needs to do, where it will work and how many people need to travel in it.

A mobile workshop is a good example. Two technicians making several stops a day may do most repairs beside the vehicle and need quick access to tools from outside. A crew staying at one site for several days may need an indoor workbench, lighting and a way to power equipment while parked. The same type of vehicle can call for very different layouts.

Describe a typical job

Tell us what the crew does from arrival to departure. Which jobs must be completed on site? Does the crew work inside the vehicle, beside it, or both? How often does the vehicle move between jobs?

This helps us work out what should be accessible from outside, what needs a dedicated workspace and what must stay secured during travel.

Share the crew size and road conditions

Tell us how many people need to travel in the vehicle, including the driver. The number of travel seats can affect the choice of cab, available space for tools and equipment, and remaining payload.

Describe the roads the vehicle will use, including the final approach to the work site. If you already have a preferred chassis, fuel type or drive configuration, share it. A description of the route and terrain gives us a starting point when those choices are still open.

Flag the requirements that are already fixed

Let us know if you have a locally available chassis, a vehicle size or weight limit, or equipment that must be carried. If a machine has already been selected, its model or datasheet helps us check dimensions, weight, power requirements and access for operation and maintenance. If selection is still open, tell us what the machine needs to do.

Example of a first enquiry

Two technicians, including the driver, visit several sites a day. They carry hand tools and common spare parts and do most repairs outside the vehicle. Most of the route is paved, but some sites have rough access. The chassis, drive configuration and onboard power are still open.

If you’re planning a special-purpose vehicle, send Fengqi a short description like this. We can use it to identify which layout and platform options are worth discussing and what information we’ll need next. If you’re ready to request a quotation, use the vehicle quotation checklist to prepare the details. Part 2 · Planning an air compressor for a mobile workshop

Part 3 · Mobile workshop payload and the 3.5-tonne limit

Part 4 · How long does a work vehicle need to stay on site?
