Konecranes is introducing the new Gottwald ESP.4, extending its Generation 6 mobile harbor crane range with a compact yet highly capable addition. The crane is aimed primarily at smaller seaside and river ports handling a growing mix of container, bulk and general or project cargo. The new model is now available for order.
According to Jörg Müller, Vice President Mobile Harbor Cranes at Konecranes, many smaller ports are transitioning toward multi-purpose operations and require equipment that combines maneuverability with flexibility. He believes the mobile harbor crane concept, originally pioneered by Konecranes, is increasingly suited to these evolving port environments.
Despite its compact footprint, the ESP.4 offers notable performance capabilities. It can handle up to 10 container rows with a lifting capacity of 30 tonnes under spreader for feeder to standard class vessels. For project cargo, lifting capacity reaches up to 100 tonnes, while general cargo handling offers up to 63 tonnes at a 24 m radius with hoisting speeds of up to 120 m/min. In bulk handling applications, the crane delivers a motor grab curve of up to 34 tonnes and throughput of up to 850 tph, positioning it as a standout in its size class.
The ESP.4 builds on more than 70 years of mobile harbor crane development and incorporates the core attributes of the Generation 6 series. Its modular drive concept supports fully electric operation with external power supply and batteries, as well as optimized diesel generator configurations. The crane also integrates smart digital features and is available on rubber tires, rail-mounted portal or barge configurations.
The launch supports Konecranes’ broader Ecolifting roadmap aimed at reducing emissions and advancing port decarbonization through solutions ranging from renewable fuels and hybrid systems to fully electrified and emerging energy technologies.
