Abstract
Apparatus for facilitating the loading and unloading of heavy ladders from the roof of a motor vehicle comprises a pair of crossbar members affixed to the roof of the vehicle that extend transversely to the length dimension of the vehicle. A four-bar linkage arrangement affixed to the rearmost crossbar member is adapted to be driven by a shaft journaled for rotation in the spaced-apart crossbar members is arranged to displace a ladder support bar to which ladder hooks are attached. A front ladder hook is attached by a coupler to the elongated shaft at the forward facing end of the ladder rack assembly where the coupler is designed to allow the shaft to be rotated through a predetermined angle before the front ladder hook will rotate with the shaft and in this way the front and rear hooks remain parallel to one another through their range of motions.
