KAR-Lehtonen offers its customers technical and legal consulting with strong expertise and extensive industry knowledge. Decades of experience in the manufacture of tanks and fluid control systems provide our experts with a comprehensive overview of the technology used and the legislation in force.

We are well acquainted with the transport laws of Finland, the Nordic countries, and the Baltics, as well as the common European Transport of Dangerous Goods Act. In this way, we can help operators outside of Finland, for example, to adapt their equipment in line with the interpretation of the Finnish ADR Act. We work closely with Nordic inspection bodies to ensure that our customers’ equipment meets all the requirements. We are also very familiar with the practices of Finnish companies (e.g. Silja Line, Finnfoam), and we help our customers adapt their equipment to be compatible
with these operators.

Our consulting services are utilized by transport companies and various industrial operators, both in Finland and abroad.

A strong expert in the field – solid local knowledge

We want to be a forerunner in the field, which is reflected in our operations as a continuous investment in product development and the up-to-date know-how of our experts. A wide network of partners, contacts with leading inspection bodies, technology expertise, and industry know-how enable us to provide consulting services, no matter what your needs.

When the customer’s equipment is manufactured by us or renewed based on our expertise, we can guarantee that it will be suitable for the harsh weather conditions in the Nordic countries and the current regulations concerning dimension and mass. We also consult our customers on the optimal structures for the equipment, from the perspectives of safety and economy. For example, how to make the liquid in the tank slosh less, make the vehicle more stable, and make the use of the equipment more productive.

Benefits of consulting – cost savings throughout the lifecycle

When the customer acquires new equipment, we are happy to offer our expertise in choosing the right platform, tank, and equipment needs. We can also help make the equipment as versatile as possible, e.g. suitable for several different products. By exploring the customer’s needs, we ensure that the features serve the use ideally and that the customer does not invest in unnecessary equipment. When consulting, we also ensure that the customer receives the highest possible payload for their equipment and the best return on investment in the long run.

In addition, we provide a consulting service for modifying old equipment to comply with new regulations.

Consulting also saves our customers time, as they do not need to familiarize themselves with country-specific legal matters. By utilizing our consulting service, the customer can ensure that the equipment meets the requirements of the law and regulations, thus avoiding additional adjustments.

KAR-Lehtonen – referenssit

Meillä on ollut KAR-Lehtosen kanssa pitkäaikainen ja hyvä yhteistyö ja ollaan oltu tyytyväisiä heidän palveluun. Me ollaan tienpäällystyksessä Suomessa merkittävä tekijä ja ajetaan päällystykseen bitumia. Heillä on meidän toiminnan onnistumiseen ratkaiseva merkitys ja ovat sen täyttäneet. Lisäksi kehitystä on heillä tehty koko ajan parempaan suuntaan.

Kokemukseni on erittäin positiivinen KAR-Lehtosen toiminnasta. Kehitimme yrityksellemme uutta toimintaa ja siihen liittyen tilasin KAR-Lehtoselta alipaine/-imusäiliön ja meillä ei ole aiempaa kokemusta kyseisenlaisesta säiliöstä. Saimme yhteistyössä toteutettua juuri meille parhaan laitteen. KAR-Lehtonen oikeasti toteuttaa sen mitä asiakas haluaa ja pystyy myös asiakkaalle uusissa jutuissa antamaan neuvoa.

Vi har haft ett mycket gott samarbete med KAR-Lehtonen i över tjugo år. De har byggt ett antal olje-/ bitumen- och gassläp åt oss. De har även färdigställt alla våra tankbilar. Vi är väldigt nöjda med deras service.
