STS Cranes
Ship-to-shore expertise.
Ship-to-shore cranes are the most critical assets in any container terminal. ELS provides comprehensive engineering services for STS cranes — from emergency repairs and spare parts to full modernisation and electrification projects.
Complete STS Crane Support
The heartbeat of container handling
STS cranes work around the clock loading and unloading container vessels. With cycle times measured in seconds and daily throughput in the thousands, even minor breakdowns translate into significant operational and financial impact.
All manufacturers, all generations
ELS engineers work on STS cranes from ZPMC, Liebherr, Konecranes, Paceco, and other manufacturers — including older models where OEM support has ended. Our brand-independent approach means we deliver the best engineering solution, regardless of the original equipment supplier.
Our STS crane services cover the complete machine: hoist and trolley drive systems, boom and girder structures, spreader mechanisms, anti-sway systems, electrical cabinets and PLC controls, festoon systems, and operator cabins.
We also carry out major modernisation projects including diesel-to-electric conversion, semi-automation upgrades, structural reinforcements for larger vessel outreach, and control system replacements — extending the useful life of your STS fleet by decades.
Modernisation & Electrification
Many STS cranes in operation today were built 20–30 years ago. Rather than replacing these multi-million-dollar assets, ELS offers targeted modernisation that restores and often exceeds original performance levels.
Our modernisation scope includes control system upgrades from relay logic to modern PLC/SCADA, drive system replacements, structural life extension through reinforcement and fatigue repair, and full electrification of diesel-powered units — reducing operating costs and environmental impact.
