BENEFITS• The Tandem T45 spreader offers terminals the highest level of productivity andversatility, with the capacity and flexibility to handle all possible combinations of20', 40', and 45' containers quickly and efficiently. It can also handle four 20' containerssimultaneously and separate the 20' containers longitudinally between 0 and 1,6 meters.• The Tandem 40/45 spreader is able to twin-lift two 20', 40', or 45' containers withoutthe need, as in the Tandem fixed-length version, for change-out.• This is a proven spreader design field-tested in high-throughput European and Asianterminals.• Customers with a high number of empty 40' containers may want to give specialconsideration to the productivity advantages of the Tandem.• The Tandem headblock is necessary for the efficient handling of the Tandemspreader line.The Separating T45 spreader offers the highest level of productivity and versatility, butrequires a higher-capacity container crane. Tandem T45 spreader weight is an estimated31 tonnes. To fully utilize the lift capacity of the spreader requires a high crane capacity,but most customers will rate 20 foot containers to a maximum of 20-25 tonne, therebyresulting in a required crane capacity of 115-135 tonne in the ropes.Tandem ProductivityThe Tandem 40/45 spreader is based on proven Bromma spreader design, as it uses theSSX40/45 spreader as its standard base. A terminal planning to utilize the full 70 tonnecapacity under the spreader will need crane capacity of approximately 100 tonne in theropes. As such, the Tandem 40/45 can be used without restriction on many last-generationcontainer cranes already in service today. Customers who handle very few 45' containersmay wish to consider the 40' version of the Tandem 40/45. This will save approximately2 tonne in spreader weight.Bromma Tandem spreaders are feature-rich. The adjustable pusher with memory functionkeeps a pre-set space between the spreaders, reducing the swinging of the two spreadersand simplifying the entering of ship cell guides. Long side flippers mounted on an inclinedbase, and rounded end beams, avoid jamming in cell guides. The four wagons can be movedindividually to allow skewing and gravity point adjustment, should this be needed. A memorysystem allows a pre-set positioning distance between the spreaders. Chain suspension allowsTandem to handle containers of different height. Eight powerful flippers with large scoopsin optimal configuration allow Tandem to handle different combinations efficiently.The Bromma Tandem Headblock with adjustable pulley wheel distance keeps the gravitypoint of the two containers between the pulley wheels center in Tandem mode. Whenoperating with a standard spreader, the pulley wheels will retract to normal headblockwidth. Pulley wheels move from standard (750-1000 mm) up to 2,6 metres. Bromma canalso provide a fully automatic electrical plug/socket interface and will offer to modify theexisting crane electrical interface and communication system to enable the handling ofTandem spreaders.12
