With the Bromma adjustable twin-lift spreader STS45 a larger percentage of above-deck containers can be transported in twin-lift mode.
This is possible as the spreader can move two 20 foot containers from a spacing of 0 to 1.6 metres (0 to 5 foot) under full load while suspended under the twistlocks.
Two containers can be moved synchronised towards one another and apart from one another. The movements can be done at anytime in the crane cycle and are mechanically controlled to be symmetrical. There is no stopping time to change the container spacing.
The telescopic spreader STS45 is of rectangular frame construction enabling easy location on containers. The spreader is as standard equipped with 4 x 10 tonnes lifting lugs in the corners of the end beams for heavy lifts and for handling damaged containers. The design with recessed end beams makes handling of lashing frames and hatch covers possible. All motions of the spreader are controlled from the driver’s cab and there are provisions made for signals in the cab indicating the position of the twistlocks and landing pin status.
Made of high quality steel, the standard STS45 spreader provides high lifting capacity with a low nominal tare weight thanks to the box design of the telescoping beams and the main frame. The spreader is designed in accordance with DIN 15018 H2B4. All components can be easily assembled, adjusted, removed and are accessible for inspection and maintenance.
The spreader comes with the SCS² Spreader Communications System, reducing and preventing downtime through improvements in the area of electrical connections. It will also shorten downtime through faster spreader fault diagnostics.
