2 Product description
2.1 Function
Open tray dispensers and open sided basket dispensers transport and
dispense items at a constant height.
Open tray dispensers and open sided basket dispensers consist of
a base unit for stacking equipment and a platform for baskets or
trays, suitable for the stacking of baskets or trays. The items rest
securely on the platform for baskets or trays. As the load increases,
the spring-loaded platform for baskets or trays sinks. As the number
of items decreases, the platform for baskets or trays rises. Open tray
dispensers and open sided basket dispensers therefore ensure that
the items can be removed at a constant height.
