The Vertical Transfer Unit (VTU) speed depends on the application’s throughput requirements. 100-180 FPM is a typical range. Higher speeds are available if required.

Nominal speed of RAFT is 2 meters per second. Top travel speeds can vary for loaded and unloaded, as well as load specific travel speeds and acceleration/deceleration curves.

The RAFT robot charges in 30 minutes with 480 volt 3-phase power. 1- hour and 2-hour charge cycles are available if the house power is limited in amperage or voltage.

Typically, the RAFT robot runs 4-6 hours between charges based on a variety of factors including empty vs loaded travel time, load weight, operating temperature and idle time.

The on-board battery management system provides feedback to SwiftCurrent, our WCS system, on battery status. Once the battery reaches pre-set percentage, the RAFT robot automatically completes its current task and is routed to the nearest available charging station. The percentage is variable and can be changed based on system performance.
