  • Vehicle load lifting and lowering apparatus
    Patent number: 3945516
    Abstract: A vehicle load lifting and lowering apparatus, which can be used as a vehicle tail lift to lift and lower loads of up to 8 tons between the level of the ground on which the vehicle stands and the level of the vehicle's load carrying deck, comprises a pair of parallel spaced apart guide columns which can be swung via a deformable articulated linkage towards and away from the vehicle. Runners slidably mounted in equal numbers on each column support between them a load carrying platform, and hydraulic rams power the runners (and hence the platform) up and down the columns during load lifting operations.
