STS Spreader

The RAM3900 series is a twin lift telescopic spreader for ship to shore Cranes. The 3900 model is all electric powered, suitable for customers who want to ensure a reliable quayside operation and be more sustainable.

The 3900 series is a telescopic twin lift ship to shore container spreader, which is powered all electrically and controlled from the crane's cabin. The spreader can be designed to interface with new or existing crane headblocks and electrical communication systems. In twin lift mode, the RAM ‘CentreSpread’ function allows the spreader's centre gap to be adjusted when two 20ft containers are handled and not set at the standard centre gap distance. The centre gap can be adjusted when the spreader is either unladen or lifting two containers. Moreover, the spreader is fitted with a memory positioning system and automatic positioning system  to “memorise” the gap between the two 20ft containers.

Improve performance

With the ability to lift more containers, the container handling cycle will be more productive.


Also, with the auto positioning and memory system, the spreader can be in a landside and a seaside position, enabling the crane operator to return to either of these positions. The telescopic arms also allow the spreader to pick up a variety of container sizes.


As the spreader is powered electrically there are no CO2 emissions emitted. In addition, as the spreader is powered all electrically, it operates quieter.
