How Long Does a Work Vehicle Need to Stay on Site?

Plan onboard power and crew facilities for a mobile workshop or engineering rescue truck based on its longest assignment and available site services.

How Long Does a Work Vehicle Need to Stay on Site?

Custom Vehicle Briefs · Part 4

“We need the vehicle to work independently.”

How long will the vehicle stay on site, and what can the site reliably provide? A mobile workshop may only need power for tools and lights during a short repair. An engineering rescue truck may stay through a shift change and need to support equipment and crew breaks for longer.

Plan onboard power around the assignment

Tell us which equipment needs to run at the same time, how long it runs and what must stay on if site power is interrupted. A short repair without a socket may need onboard power. A longer assignment with reliable site electricity may use it for some equipment.

Decide what the crew needs while parked

For a crew working in shifts, a place to sit and take a break close to the work area can be useful. If the site already provides a suitable break area, that may leave more room on the truck for equipment.

The yellow engineering rescue truck pictured here has a compact bench area and ceiling air conditioning. For your own layout, tell us how many people need to use the space at once, whether it needs cooling while parked and whether the air conditioning will run alongside the main equipment. If the crew needs overnight accommodation, include that in the brief from the start. It affects the space and payload available for the job.

What to include in your enquiry

Describe the longest assignment you expect, what the crew must get done and what the site can reliably provide. A first enquiry could read like this:

The truck may stay at one site through a shift change. The crew takes short breaks on site and returns to base to sleep. Site power is sometimes available. Please check which equipment needs to keep running when it isn’t.

Send your project requirements, or see our emergency rescue vehicles for examples of different mission layouts.
