The right sort

USPS rolling out new sorting machines

The small delivery unit sorter machine can sort at least 2,250 pieces an hour and requires less than 1,500 square feet of space.

The Postal Service is rolling out new machines specifically designed to help delivery units expedite package processing, an important objective of Delivering for America, the organization’s new 10-year plan.

Seven small delivery unit sorter (SDUS) machines have been installed so far, with six installed in April; another 93 are slated for installation before the start of this year’s holiday season.

SDUS machines require less than 1,500 square feet of space — depending on the number of separations — compared to larger automated delivery unit sorter (ADUS) machines, which average 2,000 square feet.

“The small delivery unit sorter uses the best assets of the larger mail processing equipment in a scaled-down size,” said Roxane Weaver, a full-time regular clerk at the York, PA, Post Office, where the first SDUS was installed last November.

An SDUS is capable of sorting at least 2,250 pieces an hour, compared to an ADUS, which can process a minimum of 2,500 pieces an hour.

However, the York Post Office’s SDUS regularly exceeds 3,000 parcels an hour.

“It’s incredible to process so many parcels in such a short time,” said Allison Klinedinst, a York postal support employee.

SDUS deployment is one component of Delivering for America, which also calls for investments in technology, training, a new vehicle fleet and the modernization of the USPS network, among other improvements.

Said York Postmaster Michael Becker: “It has been extremely exciting to see our employees embrace the small delivery unit sorter and become an essential part of the Postal Service’s modernization.”
