The load-lifting platform of a lifter car consists of a stationary frame(22) having a support prop(41) which is lifted and lowered by a lifting device(40) and a movable frame(26) having a number of casters(30) and being coupled to the stationary frame by a number of push pin rods(28). The stationary frame has a number of prolonged legs(21) horizontally arranged with uniform gaps for receiving the protrusions(23) of the movable frame. The movable frame has a lateral protrusion(25) a number of prolonged protrusions(23) on a base plate(24). When unloading the load, the load with a upper plate(23) spanned on the prolonged protrusions(23) of the movable frame may be easily drawn by a hauling ring(33) prepared at the side of the lateral protrusion with casters after removing the coupled pin rods.
