The winch actuates a hitch-hoisting cable which may be attached to a truck hitch to lift it from the bed of a truck and then lower it to a storage location. The hitch hoist may have two mounting arms, two booms, and a winch on a plate with width variability built into the bolting slot patterns. The booms extend from the mounting arms near the winch plate to form an obtuse angle between the booms and the arms. From the horizon, the angle may be viewed to be that of approximately forty-five degrees (45°). An axle is affixed near the end of the booms and holds a cable wheel which guides a cable and hook to raise and lower the hitch with the winch. ## Claims ### Claim 1 A device for lifting and lowering a fifth wheel hitch for a gooseneck trailer, the gooseneck trailer having a pin box and a king pin to accommodate towing of the fifth wheel trailer, the device comprising: an arm combination, wherein the arm combination has a proximal end and a distal end, the proximal end of the arm combination affixes to the gooseneck trailer pin box, the distal end of the arm combination terminates in a receiver, a boom assembly, the boom assembly inserts into the arm combination receiver and extends at a substantially vertical angle, a winch mounted on a plate, the plate being secured near the distal end of the arm combination, a cable secured in the winch, the cable being supported by and tracking with the angle of the boom assembly and extending a distance to reach the hitch, the cable terminates in a hooking mechanism, wherein the cable hooking mechanism attaches to the hitch and lifts and lowers the hitch with force actuated by the winch. ### Claim 2 (depends on 1) A device according to claim 1, wherein the arm combination further comprises a first arm and a second arm. ### Claim 3 (depends on 2) A device according to claim 2, wherein the first arm is affixed a first side of the fifth wheel trailer pin box and the second arm is affixed to a second side of the fifth wheel trailer pin box. ### Claim 4 (depends on 1) A device according to claim 1, wherein the boom assembly further comprises a first boom and a second boom. ### Claim 5 (depends on 1) A device according to claim 1, wherein the arm combination further comprises a first arm and a second arm, the first arm is affixed a first side of the fifth wheel trailer pin box and the second arm is affixed to a second side of the fifth wheel trailer pin box, the first arm terminates in a first receiver, the second arm terminates in a second receiver. ### Claim 6 (depends on 5) A device according to claim 5, wherein the boom assembly further comprises a first boom and a second boom, the first receiver receives the first boom and the second receiver receives the second boom. ### Claim 7 (depends on 6) A device according to claim 6, wherein the first boom and the second boom each further comprise an axle support. ### Claim 8 (depends on 7) A device according to claim 7, wherein the axle support secures an axle. ### Claim 9 (depends on 8) A device according to claim 8, wherein the axle secures a cable wheel to guide the cable. ### Claim 10 (depends on 1) A device according to claim 1, wherein the boom assembly further comprises an axle. ### Claim 11 (depends on 10) An device according to claim 10, wherein the axle is secured near a distal end of the boom assembly. ### Claim 12 (depends on 10) A device according to claim 10, wherein the boom assembly further comprises a cable wheel, wherein the cable wheel turns on the axle and guides the cable. ### Claim 13 (depends on 1) A device according to claim 1, wherein the hooking mechanism of the cable attaches to the hitch and the winch retracts the cable to lift the hitch. ### Claim 14 (depends on 1) A device according to claim 1, wherein the hooking mechanism of the cable attaches to the hitch and the winch releases the cable to lower the hitch. ### Claim 15 (depends on 1) A device according to claim 1, wherein the cable works in concert with the winch mounted on the plate, the boom assembly, an axle assembly, and the hooking mechanism to lift the fifth wheel hitch. ### Claim 16 (depends on 1) A device according to claim 1, wherein at least the arm combination, the winch mounting plate, and winch are permanent accouterments to the fifth wheel trailer pin box. ### Claim 17 (depends on 1) A device according to claim 1, wherein the boom assembly extends from the arm combination to form an obtuse angle with the arm combination. ### Claim 18 (depends on 1) A device according to claim 1, wherein the substantially vertical angle is approximately forty-five degrees (45°) from horizontal. ### Claim 19 (depends on 1) A device according to claim 1, wherein the arm combination is secured to the trailer pin box with spacing apart from the king pin such that normal towing operations are not compromised. ### Claim 20 (depends on 1) A method for using the device in claim 1 to remove the fifth wheel hitch from a vehicle, the method comprising: a. permanently affixing portions of the hoisting device to the fifth wheel trailer pin box; b. towing the trailer normally until towing is complete and the vehicle is stopped; c. detaching the fifth wheel trailer kingpin from the fifth wheel hitch of the vehicle when trailer towing has ceased; d. parking the fifth wheel trailer with the support of jacks; e. aligning the hitch in the vehicle under the hoisting device; f. parking the vehicle and unbolting the hitch from the vehicle; g. attaching the hoisting device to the fifth wheel hitch on the vehicle; h. using the device to hoist the hitch off of the vehicle; I. driving the vehicle forward until the hoisted hitch is no longer over the vehicle; j. activating the hoisting device to lower the hitch onto the ground. ### Claim 21 (depends on 20) A method according to claim 20, wherein the method further comprises: k. detaching the hoisting device from the hitch. ### Claim 22 (depends on 1) A method for using the device in claim 1 to lift the fifth wheel hitch into a vehicle, the method comprising: a. permanently affixing portions of the hoisting device to the fifth wheel trailer pin box; b. locating the fifth wheel hitch below the hoisting device; c. attaching the hoisting device to the hitch; d. activating the hoisting device to raise the hitch to a sufficient height that the vehicle may fit under hitch; e. backing the vehicle to align the hitch attached to the hoisting device under the location for attaching the trailer hitch in the vehicle; f. parking the vehicle; g. lowering the hitch onto the vehicle and bolting the hitch to the vehicle; h. attaching the fifth wheel trailer kingpin to the fifth wheel hitch of the vehicle when the towing of the trailer is desired; and I. towing the trailer normally. ### Claim 23 (depends on 22) A method according to claim 22, wherein the method further comprises: j. detaching the hoisting device from the hitch.
