About RAM 3900 Series
The 3900 series is a telescopic twin lift yard 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.
