In continuous casting equipment having a path of transport of castings defined by roll segments and having a curved section and a horizontal section, an apparatus for hoisting the roll segment comprises a pair of pivotal guide rods pivotably supported by a trolley disposed above the horizontal section, a pair of fixed guide rods arranged on the opposite sides of each of the roll segments defining the curved section, and a pair of fixed circular arc rails extending along the paths of movement of the free ends of the pivotal guide rods. A truck, movable on the rails and engageable with the pivotal guide rods, is reciprocatable along the rails to align the pivotal guide rods with a desired pair of fixed guide rods for hoisting the corresponding roll segment along the fixed guide rods to the pivotal guide rods in alignment therewith. Pairs of cavities are formed in the rails in corresponding relation to the pairs of fixed guide rods, and a pair of rear wheels on the truck, when engaged in the desired pair of cavities, locks the truck to the rails reliably, whereby the pivotal guide rods engaged with the truck are indirectly locked to the rails.
