Stacking in tight spaces

An AmbaFlex e-commerce customer from Germany wanted to put a spiral into an old elevator shaft. Although a relatively common request, this one needed to be stacked due to a combination of height, heavy loads and desired throughput. Traditionally, when stacking spirals on top of each other, they need a connection loop to join them together.

This loop is a U-shaped horizontal conveyor section connecting the upper and lower end of the individual spirals in question. AmbaFlex says these extruding parts make it impossible to fit in a tight shaft.

AmbaFlex invented a new technical solution to resolve this issue. A return part shaped like an upside down ‘J’ that eliminates the need for a loop. This part keeps the stacked spirals as compact as possible, enabling it to fit into tight places such as elevator shafts.
