  • Patent number: 11085202
    Abstract: In embodiments, the tarmac light fixture removal tool comprises a support base, a jack, a collar lifter, and a spacer. The tarmac light fixture removal tool may pull a collar of a light fixture. As a non-limiting example, the collar may be inset into a tarmac such that the top of the collar is flush with the tarmac or is below the level of the tarmac. The support base may rest upon the tarmac, straddling the collar. The collar lifter may removably couple to the collar. The spacer may push a plurality of hooks on the collar lifter outwards such that the plurality of hooks engage with a lip on the collar. The jack may push the collar lifter up relative to the support base when actuated, thus lifting the collar.
