The E-one's all electric trolley.

Kalmar is launching the E-One, the first all-electric rubber-tyred gantry (RTG) crane.

According to a company statement, the E-One is "suited to any operation around the world" and does not need hydraulics to work.

The RTG has a low-emission diesel engine and is fitted with an all-electric trolley, wheel turning and spreader.

The all-electric wheel turning now replaces the commonly used hydraulic turning and locking system for wheel positioning.

The all-electric Bromma spreader is a reeved-in design, different to the conventional RTG where the spreader is attached to the headblock.

Based on new intelligence in RTG movements, the RTG offers fuel savings of up to 30 per cent. Electric power is used only when needed while in conventional RTGs, the hydraulics run constantly.

Kalmar's latest RTG orders include 10 16-wheel models for Jeddah, Saudi Arabia, five 16-wheel units to Liscont, Portugal, four eight-wheel models each to Gdynia, in Poland, Kumport, in Turkey and Djibouti; one 16-wheel unit to Petrolesport, at the Port of St Petersburg; and six 16-wheel models to the Kenya Port Authority.
