Abstract: A mechanical track restraint that can be mounted to a loading dock without any modification whatsoever to the loading dock or to the concrete pad that is poured in front of the loading dock on which a truck sits during the loading process. The mechanical track restraint can be bolted onto the dock, can be removed and replaced with another device, moved to another location easily and quickly, and can be installed and/or repaired quickly. The device includes a base having a pipe and angle irons welded to the pipe to hold the pipe in place. Fitted within the pipe is a dowel and a spring that coils about the dowel. Fitted over the dowel and spring combination is a holding tube which telescopes within the pipe. The pipe has a slot cut in the front of it so that a hook which is hingedly connected to the holding tube can extend out from the pipe and travel in an up and down direction to raise and lower the hook. Sleeves are welded to the holding tube and the hook includes pivot arms extending into the sleeves.
