Abstract
Abstract A latch member is affixed near one end of a vehicle body and may be in the form of a rigidly supported horizontal rod spaced from the body. A latch is attached to a loading dock in position for registration with the rod as the vehicle body approaches the dock. The latch automatically releasably engages the latch rod to releasably hold the vehicle body to the dock to prevent relative movement between the body and the dock during load transfer between the dock and the body. The latch may be pivoted or otherwise movably adjustable relative the dock to receive rods at different rod positions relative the dock. Signal lights are provided to indicate the latch condition. A remote latch control is provided for operation from the vehicle operator station.
