STS Trolleys

STS trolley track

Ready for Ultra Large Container Vessels (ULCVs)

The size of container cranes has more than doubled since the first container cranes were built in the late 1950s. Over the years, Ship-to-Shore cranes (STS) have been updated and upgraded with twin-lifting capacities and increased productivity requirements resulting in higher duty cycles, trolley speeds and accelerating & breaking forces.

This has led to higher expectations of the trolley rail systems.

Gantrex’ range of specific products and services for STS crane trolleys are engineered to meet the market demand for more reliability tailored to the larger and faster cranes used to quickly load/unload Ultra Large Container Vessels (ULCVs). Our specialized short rail and trolley rail installers boast worldwide experience to inspect, repair and install trolley rail systems to the highest quality standards in the industry.
