  • Portable reinforced loading ramp
    Patent number: 4042992
    Abstract: A portable reinforced loading ramp is described that is transversely expandable to enable the ramp to be used for loading automobiles. The ramp is constructed with two body sections having means for interconnecting the two body sections to hold the two sections securely together when the ramp is in the contracted position. The interconnecting means includes two longitudinally spaced alignment and locking assemblies for holding the two sections securely together to prevent the two sections from spreading under high load conditions when in the contracted position and for quickly disconnecting the two sections to enable the two sections to be spaced from each other to accommodate wide loads such as an automobile.
