EcoCrane Hybrid RTG Battery

The EcoCrane Battery Hybrid System is a unique, proven solution that retrofits existing electric rubber-tired gantry (RTG) cranes with battery-hybrid technology. This allows crane owners to realize substantial cost savings, without having to purchase a new crane.

How EcoCrane works

The power unit consists of a small electric generator and a diesel engine, producing less than 200 hp. To minimize fuel consumption and emissions, the engine only runs while the batteries charge. And unlike most diesel-hydraulic or diesel-electric cranes, it reduces the RTG’s traditional genset by a factor of 4, while still providing enough power to operate at full capacity.

How EcoCrane helps

EcoCrane replaces your existing RTG’s large diesel engine with a minimal (~ 150 hp) diesel engine/generator combo. This solution reduces idle time and fuel costs by recovering all the regenerative energy that would otherwise be wasted. Plus, EcoCrane minimizes noise, maintenance costs, and up to 99% of emissions. Make the transition and you may even be eligible for government and environmental grants.

Why choose EcoCrane?

For over 20 years, Mi-Jack has been committed to designing and manufacturing innovative, new high-density battery technology. Our team has integrated hybrid systems into both small and large industrial applications, ranging from 100kWh up to 1 MWh.

Regenerative Charging

Our EcoCrane energy solution uses a lithium-ion battery pack to perform functions like container lifting and propulsion. Each time the operator lowers a load or presses the brakes, the Li-Ion system “recovers” built-up kinetic energy that would’ve typically been wasted. Recapturing and storing that energy inside the battery pack boosts efficiency, which translates into a substantial reduction in operating costs.
