About Gantrex
Gantrex is a supplier specialized in cranes and crane rail systems, offering production, distribution, installation and maintenance from a single source. The portfolio includes rail fastening systems (clips), elastomer pads, crane rails to DIN 536 and ASCE profiles, crane wheels and wheel assemblies as well as material components made of steel, cast iron and elastomers. In addition, the company offers engineering services (CAD, FEA, rail design), rail welding (enclosed arc, aluminothermic, flash butt), installation, repair, surveying and diagnostics such as 3D scanning, vibration analysis and continuous crack monitoring. The systems are used in ports, shipyards, steel and aluminium mills, warehouses, the automotive industry and wind turbines. With more than 500 employees, 20 local offices and over 50 years of experience, Gantrex states that it is the global market leader for Crane Rail Solutions; in the last decade around 4,500 km of pads and 20 million clips were produced.
