The LK503/605 SS SF lowboy trailer carries 60 tons in 12 feet and has a 20-inch loaded deck height. A 24- and 36-inch flip extension can be added on the gooseneck. It can also run two additional axles in either a close coupled position or as a separate axle group.
The last 8 feet of the trailer is recessed with pierced-steel plates to create a bucket well, which reduces overall height when hauling long-reach excavators. A push-pull, manual raise-and-lower valve reduces the likelihood of suspension damage, Load King says.
