Welcome to Princeton Delivery Systems,
the leading manufacturer of truck mounted
forklift products and the home of the

Bottle Gas

The Princeton PiggyBack® Delivery System is a proven method for delivering bottled gas that has revolutionized customer service and delivery efficiency.

The Concept

Since 1968, the European Gas Industry has used truck-mounted forklifts for their bottle deliveries. A PiggyBack® can be mounted behind almost any existing truck or trailer. In some cases PiggyBacks can even be combined with existing lift gates. The unit is ready for operation in less than 60 seconds. Instead of rolling bottles, the driver can pick up an entire pallet, and get it close to the exchange point. Or, it can be used to exchange entire pallets. The PiggyBack® works with any pallet system (eg. Weldcoa) and can increase your productivity with as much as 35%.

The Solution


Introducing the brand new upgrade to the tried and true PiggyBack Z1 - The Princeton PB36! This smaller and lighter model forklift can be carried behind "beverage-style" trailers with roll-up doors. With retracting wheel arms, the PB36 will even mount to the rear of trailers which have rear axles positioned fully to the rear of the trailer.
