A system for moving a vehicle component of a vehicle relative to a structure of the vehicle during installation of the component on the structure, the system comprising: spaced-apart first and second supports mounted to a base on opposite sides of a component bay region of the base, the first and second supports extending upwardly from the base; a lift frame including a crossbeam extending between the first and second supports along a beam axis , and a pair of spaced-apart cambered truss assemblies secured to the crossbeam and configured to be attached to and support the vehicle component relative to the crossbeam; first and second crossbeam support assemblies on the first and second supports, configured to support the crossbeam for rotation of the crossbeam relative to the first and second supports, the first and second crossbeam support assemblies being movable along the first and second supports; a first lift mechanism configured to move the first crossbeam support assembly along the first support in response to a first control signal; a rotational drive mechanism configured to rotate the crossbeam about the beam axis relative to the first and second crossbeam support assemblies in response to a second control signal; and an electronic controller operatively coupled to the first lift mechanism and the rotational drive mechanism , configured to generate the first control signal controlling operation of the first lift mechanism to move the first crossbeam support assembly along the first support , and to generate the second control signal controlling operation of the rotational drive mechanism to rotate the crossbeam relative to the first crossbeam support assembly , to thereby change a position of the vehicle component relative to the vehicle . spaced-apart first and second supports mounted to a base on opposite sides of a component bay region of the base, the first and second supports extending upwardly from the base; a lift frame including a crossbeam extending between the first and second supports along a beam axis , and a pair of spaced-apart cambered truss assemblies secured to the crossbeam and configured to be attached to and support the vehicle component relative to the crossbeam; first and second crossbeam support assemblies on the first and second supports, configured to support the crossbeam for rotation of the crossbeam relative to the first and second supports, the first and second crossbeam support assemblies being movable along the first and second supports; a first lift mechanism configured to move the first crossbeam support assembly along the first support in response to a first control signal; a rotational drive mechanism configured to rotate the crossbeam about the beam axis relative to the first and second crossbeam support assemblies in response to a second control signal; and an electronic controller operatively coupled to the first lift mechanism and the rotational drive mechanism , configured to generate the first control signal controlling operation of the first lift mechanism to move the first crossbeam support assembly along the first support , and to generate the second control signal controlling operation of the rotational drive mechanism to rotate the crossbeam relative to the first crossbeam support assembly , to thereby change a position of the vehicle component relative to the vehicle . <EOS>
