Years ago, it was the Princeton PiggyBack® forklift that helped transform sod delivery from a grueling, labor-intensive job into a 20 minute stop for a truck driver, making it the hands-down favorite of sod professionals, everywhere. With its exceptional maneuverability and highly compact design, today’s PiggyBack® remains the industry choice for the 21st Century!

The Concept

The PiggyBack® truck-mounted forklift enables your driver to spot-deliver sod and similar materials precisely where your customer wants them, faster and easier, on virtually any work site with unmatched stability. A PiggyBack® can increase efficiently both by eliminating virtually all double-handling and by reducing delivery related product damage. It also is invaluable for pickups or for correcting misplacement of products on the job site.

Princeton's PiggyBack® Truck-Mounted Forklifts are available in many, different models with a wide range of available lift heights...capacities up to 7,000 lb... and other, special features that allow it to be configured to your specific delivery requirements. All PiggyBack® units mount in less than a minute behind virtually any truck or trailer for easy transport to and from the job site.

If you currently use towed or trailer carried forklifts, you already recognize the benefits of having a portable unloading unit with your delivery vehicle. The Princeton PiggyBack® Truck-Mounted Forklift provides all these benefits in a highly efficient package that eliminates the complications of towed vehicles.
