This low weight option holds the trailer floor at ride height during loading and unloading operations.
Hendrickson offers fleets a variety of air exhaust (dump) valves to prevent dock walk. Our line of automatic and manual systems provides an easy and inexpensive way to overcome this loading dock concern. For operators demanding more than dock walk prevention, we developed Surelok. This low weight option holds the trailer floor at ride height during loading and unloading operations. When the trailer's parking brakes are set, a pair of supports automatically swings into place over the suspension beams, locking the trailer solidly at ride height. With high-strength steel construction, Surelok is rugged, reliable and maintenance-free. Surelok is currently available as an option on Hendrickson HK190/230 and Vantraax Sliders.
