Tracked dumper and buggy models
Allen Engineering Corporation offers two concrete placing tools, the AT19S track buggy and ATD3300 track dumper.
Together, the two machines give rental centers the ability to serve contractors across the spectrum of concrete placing applications. From jobs requiring a compact, maneuverable buggy to projects demanding greater hauling capacity and productivity. For rental operations, that means more versatility from the fleet. For contractors, it means access to purpose-built equipment designed to withstand demanding jobsite conditions and keep material moving where it needs to go.

AT19S: Big capacity in a maneuverable package
The Allen AT19S brings substantial hauling capacity to the track buggy category while maintaining a compact footprint designed for maneuverability on active job sites. Powered by a 21-horsepower Kubota D902 diesel engine, the AT19S features a 19-cubic-foot steel bucket, 2,900-pound payload capacity, rubber tracks for added traction and load support, and a fully enclosed engine compartment. Its bucket provides a 90-degree dump angle and 180-degree pivot, giving operators the ability to accurately place material without constantly repositioning the entire machine.
At just 38.5 inches wide, the AT19S is well-suited for jobs where contractors need significant capacity while still navigating tighter working areas. Work and travel speed settings allow operators to control the machine precisely during placement and move efficiently around the job site between loads.
For rental centers, the AT19S offers a versatile option that can serve concrete contractors as well as customers moving stone, dirt, gravel and other bulk materials.

ATD3300: Step up the capacity
When production demands increase, the Allen ATD3300 track dumper provides the next step in hauling capability. Powered by a 20.3-horsepower Kubota D902 diesel engine, the ride-on ATD3300 offers a 3,300-pound payload, 29 cubic-foot bucket capacity and a top speed of 7.5 mph. Its durable steel bucket also delivers a 90-degree dump angle and 180-degree swivel, allowing operators to move larger loads and place material where it is needed with fewer positioning adjustments.
Rubber tracks and generous ground clearance provide mobility across changing job site conditions, while the centrally positioned adjustable operator seat can be accessed from either side of the machine. A foldable ROPS adds operator protection while maintaining the machine's job site-focused design.
With the ability to move up to approximately one yard of material, the ATD3300 is built for contractors who need to reduce trips, move more material per cycle and maintain production on larger placing applications.
Two machines. one complete placing strategy
While the AT19S and ATD3300 serve different ends of the placing spectrum, both are designed around the same goal: move more material efficiently and put it where the contractor needs it; every time.
The AT19S is the choice when maneuverability and a narrower footprint are priorities. The ATD3300 answers applications where greater bucket capacity, payload and travel speed can increase production. That distinction makes the two machines especially valuable to rental fleets.
