Corporate Trapex


Trapex was conceived thanks to the alliance and vision of two companies with an extensive experience of more than 35 years in the railway sector and more than 15 years in the manufacture and installation of counterweight trap doors. Repsinter, a company specialized in engineering and commercialization of railway products and MAXFOR, a company focused on production, assembly and maintenance.

Thanks to our innovative spirit, experience and the constant search to improve the quality and safety of our products, we have perfected the operation of the mechanism of the emergency evacuation trapdoors and their respective components.

To achieve this, we destine a percentage of our sales to improve our products R+D+i+d.
