A single modification
For example, installing a new serving hatch, door, worktop, electrical point, lighting fixture or an individual piece of furniture in an existing trailer.

We design, build and equip sales and food trailers around the customer's business and how the trailer will actually be used. We take on single modifications and complete trailer projects — from planning to furniture and installation.
A working sales or food trailer isn't just a serving hatch added to a trailer. The interior, furniture, appliances, electrics, storage and working areas need to form a whole that supports daily operation.
We design and build solutions for street food, café and kiosk use, events, mobile sales and other business-specific use cases. A project can start from a ready trailer, from modifying an existing one, or from procuring a completely new sales trailer.
You can come to us with just a business idea. You don't need to have planned every technical solution, furniture dimension or appliance layout in advance. We'll go through the needs together and help build a functional whole.

You can order either an individual job or a complete trailer project. Below are the three ways our customers most often get started.
For example, installing a new serving hatch, door, worktop, electrical point, lighting fixture or an individual piece of furniture in an existing trailer.
Interior design and build for the trailer — furniture, worktops, storage solutions, electrics and the placement of appliances.
Designing and building a new or existing trailer into a whole that fits the customer's business — from structures, furniture and electrical installations through to final finish.
Sales and food trailer furniture — along with its design and installation — can also be delivered through us. Furniture is sized to the available space in the trailer, the appliances, the workflow and how the customer operates.
The goal is an interior where working is as smooth as possible and the available space is used sensibly.
You don't need to source and fit furniture through several separate suppliers. We can design the whole, deliver the furniture required for the project and install it as part of the finished trailer.

A trailer being converted for sales use often needs more extensive structural work than typical equipment fitting. We deliver the modifications based on the trailer's structure and the intended use.
Design and delivery of new serving and service hatches: opening, framing, mechanisms, locks and finishing.
New doors, modifications to existing openings and solutions that make it easier for staff and goods to move in and out.
Floor repairs and replacements, interior walls, partitions, reinforcements and other structures required by the intended use.
Steps, support legs, protective structures, boxes and other project-specific solutions built on the outside of the trailer.
An existing trailer, box body or suitable vehicle can also be assessed for conversion into a sales or service unit.
The suitability and delivery method of structural changes is always assessed per project.
The trailer's electrical system and appliance layout are designed around the appliances used, the workflow and the operating environment. We deliver project-specific electrical and lighting solutions and prepare the locations for the trailer's appliances.
The final solution is determined by the appliances planned for the trailer and the electrical capacity required.
Through Kärryhuolto.fi you can also request a quote for a completely new sales or food trailer. We help define a suitable trailer size, model, structures, serving hatches, furniture and equipment.
That way, the customer doesn't first have to buy an empty trailer and then chase down several different providers for each stage of the work. The whole can be designed from the start around the actual use.
Request a quote for a new sales trailerWhen designing a new trailer we look at things like:
Every project is designed around what happens in the trailer, the environments it's used in and the way of working that best serves the business.
What is the trailer used for, what is sold from it and what appliances are needed?
The project can be based on the customer's current trailer, a trailer to be procured or a completely new build.
We plan the working areas, furniture, storage, serving hatches and appliance locations into a functional whole.
We define the structural work, electrical installations, materials and other solutions that affect delivery.
You get a quote for the agreed scope, and the project is then delivered according to it.
The trailer is finished to the agreed level and handed over to the customer for use.
