Slip Robotics has introduced SlipLift, a platform designed to extend autonomous trailer loading and unloading beyond short-haul, high-frequency routes to include heavier freight, regional distribution, and last-mile delivery operations. The system is intended to operate without requiring changes to existing docks, trailers, or information technology infrastructure.
SlipLift represents an architectural change from the company’s earlier systems by separating the robot from the payload. Under this approach, a mobile robot moves standardized SlipCarrier trays that hold freight, allowing a smaller number of robots to serve multiple dock doors. According to the company, this configuration is intended to deliver consistent loading and unloading times while increasing dock utilization.
“We’ve always focused on removing uncertainty at the dock,” said Chris Smith, chief executive officer of Slip Robotics. “SlipLift extends that philosophy. Customers get fast, repeatable load and unload times across more routes, without adding robots or complexity.”
Slip Robotics previously deployed SlipBot for closed-loop, short-haul operations, where trailers are repeatedly loaded and unloaded on fixed routes. In those settings, the company says trailers can be turned in approximately five minutes. SlipLift is positioned as an extension of that model to environments where payload weight, route length, or dock variability has limited the applicability of automation.
The company reports that customer feedback from manufacturing, distribution, and logistics operations influenced the development of the new platform. Smith said customers sought similar loading performance for heavier freight and a broader range of routes.
SlipLift is designed to handle payloads of up to 20,000 pounds, targeting heavy short-haul applications such as food and beverage distribution, packaging, paper products, and automotive components. In regional and medium-haul distribution networks, including consumer packaged goods, cold chain facilities, and furniture distribution, the system is intended to allow automation to scale across multiple sites without requiring a dedicated robot at each dock door.
For last-mile delivery operations, SlipLift supports pre-staging of freight on SlipCarriers ahead of daily routes. This approach is intended to shorten morning load-out times and reduce driver dwell time at the dock.
“Pre-staging changes the economics of last-mile loading,” said Lauren Marneni, head of product at Slip Robotics. “When freight is ready on a SlipCarrier, loading becomes a quick, repeatable process instead of a daily scramble.”
Operationally, a SlipLift robot retrieves a loaded SlipCarrier from the dock, places it inside a trailer or box truck, and exits before repeating the process until loading is complete. Operators remain outside the trailer and use a handheld controller, while the robot manages navigation, alignment, and placement.
“Our goal was to make autonomy feel natural for operators,” Marneni said. “The operator stays in control, but the robot does the hard, dangerous work inside the trailer.”
SlipCarriers can be configured to accommodate different types of freight rather than modifying the robots themselves. When not in use, the carriers can be stacked to reduce dock space requirements.
