Tongue Twister says its trailer technology eliminates the hazardous backing of construction equipment up or down trailer ramps. Employing a swivel design, it enables users to pivot the front of a trailer without unhitching it, allowing vehicles to be safely driven directly on and off the trailer via straight-through front and rear ramp access. It comes in three types of rotation actuation: electric, hydraulic and manual. Estimated price: $5,000 to $10,000.
