Stationary transfers are roller sections used to join parallel conveyor lines by interfacing with lift/cross transfer modules. These are typically equal to or greater than one pallet length, and are electrically powered at a speed matching that of the lift/cross transfer modules. They were not designed for pallet accumulation, but are available as non-synchronous units at an extra cost option. Stationary transfers have their own support stands. Only non-synchronous units are offered with an optional queue stop at the discharge end.
