The Mark IV Tilt Tray Sorter is designed to handle fragile or large product
  at rates of up to 6,000 units per hour. The design has similar characteristics
  to the highly successful SDI Bombay Sorter but can sort products that are more
  difficult on the Bombay Sorter. The Mark IV has applications across a wide
  variety of industries.

 

  The trays can be supplied using plastic, aluminum or steel, depending on the
  application. The trays hold product captive on three sides and are slightly angled
  while moving to the appropriate destination. These attributes reduce the opportunity
  for product to fall out of trays.

 

  Though the Mark IV sorts a wide variety of products, (including Fashion Accessories,
  Full Cases, China, Glass, Books and Mailers), the unit is particularly suitable for
  handling shoes.
