Hendrickson Door Lock Assembly

Trailer walk and suspension dipping during forklift loading can create unsafe gaps at the dock, and the Hendrickson Door Lock Assembly helps stabilize the trailer during loading cycles. This SURELOK dock lock kit uses a heavy-duty mechanical arm to lock the suspension beam in a fixed position when the parking brakes are engaged. By holding a more consistent deck height, it helps keep the trailer from shifting away from the dock or sagging under the weight of heavy equipment. This air-actuated system is designed for VANTRAAX and INTRAAX slider subframes, providing a reliable safety barrier for drivers and warehouse personnel. The Hendrickson S-SR1DK100-4 keeps the suspension more stable during demanding dock work.
