Hydraulic ramps are controlled by an on-board electric over hydraulic pump. They are standard with a 5-ft. beavertail at 12-degrees and 3 ft. wide x 6 ft. long hydraulic ramps at 16-degree incline. This option may be added to almost any deck-over trailer with a capacity of 20,000 lbs. or more. 22′ main deck required for this option.
