The Heil Sentien automated side loader pairs a fast, autonomous-ready arm with the Common Body platform. Engineered to deliver the lowest Total Cost of Collection.
Every second at the curb adds up over a full route. The new Heil® Sentien™ ASL’s fast, smooth arm and high-speed compaction keep each stop short, so crews can service more homes every shift.
It’s built to be just as quick in the shop. Sentien’s key components are designed for fast, straightforward replacement, so trucks get back on route sooner.

Full position sensing tells the Sentien arm exactly where it is throughout every cycle. That precision is what makes autonomous-ready features like Auto-Lift, Pick-and-Place, and Spear Mode possible. Add Level 2 autonomous functionality, and even new operators can service carts like seasoned pros.
Sentien is built on the Heil Common Body platform, sharing 44% or more of its components with Heil front load bodies. That means fewer parts on the shelf and less for technicians to learn. And the parts that take the most wear are designed to be simple to maintain and quick to replace.
Handles carts up to 96 gallons with strength to spare
Complete grip, dump, return, and release, for faster routes
Reach carts in narrow alleys and other tight spots
High-density packing from a single in-line cylinder
Front loaders and automated side loaders often share a yard, but in the shop, they have always been two separate machines, with different parts, wiring, controls, and service procedures. The DuraPack Python, Half/Pack, and Sentien change that. Both are now built on one common body platform.
Only the hopper stays specialized, because that is where the two trucks do genuinely different work. Everywhere else, shared components, one simplified in-cab system, and major serviceability improvements mean few parts to stock, faster repairs, and operators who can move between trucks with ease.


Shared engineering designed around the people who operate and support your fleet.

Designed with operators in mind. Driver-designed, ergonomic controls and simplified interface reduce cab clutter and cut in-cab buttons by 66%, delivering a consistent, intuitive experience.

Standardized parts simplify operations. A shared body design with 44% or more common components means fewer parts to stock, easier technician training, and reduced downtime across both front and side load fleets.

Simplified controls keep critical information in one place. The in-cab display provides real-time feedback, full body control, integrated 3rd Eye® camera feeds, and easier diagnostics away from hazards and weather.

Integrated 3rd Eye cameras come built into the body for better protection, less maintenance, and clearer visibility, all with fewer failures, less downtime, and improved safety, performance, and reliability in every environment.

Simplified maintenance improves serviceability. Better access, fewer required tools, centralized diagnostics, integrated 3rd Eye feeds, and relocated tailgate locks help technicians work faster and more efficiently.

Cleaner tailgate operation improves serviceability. Tailgate cylinders are positioned away from payload in the tailgate bolster, while touchscreen controls help prevent accidental movement during transit.
