A lifting cart for assist in building construction processes using precast wall panels can include a panel handling mechanism coupled to a movable vehicle. The panel handling mechanism can include a clamping mechanism, a rotational mechanism, a linear mechanism, and a tilting mechanism. The movable vehicle can include two sets of wheels configured to move the vehicle in perpendicular directions. The lifting cart can handle the precast wall panels, from a wall panel package delivered to the construction site to the final location of the wall panels between beams of the building frame.
