Tuckunder™
Tuckunder™ liftgates mount to the chassis frame of a truck or trailer. They stow folded beneath the rear of the vehicle to provide full access to the rear doorway when not in use.
Railtrac
RailTrac models mount to the rear frame of a truck or trailer. They move straight up and down, providing a level ride cycle that runs aligned with the truck bed at all times. When stowed, the platform typically covers a portion of the rear doorway. Many models have platforms that may be lowered straight down to provide access to the doorway, or for dock loading.
