PROBLEM TO BE SOLVED: To carry a tile from the ground or a car to a roof simply, safely and efficiently by suspending a tile clamper including a mechanism which can doubly lock by a single lever on a wrecker truck. SOLUTION: In suspending tiles stacked in three rows and three layers on a pallet by a small wrecker truck row by row (40 sheets, about 150 kg) and lowering the same to be distributed to each laying space, a tile clamper including a mechanism where double lock is made by one lever 2 is suspended to perform work. That is, the tile clamper opens and closes a lower fixed frame 6 throgh a clamping open and close fulcrum point 1, and each fulcrum point of fulcrums 7-9 by the vertical motion of the lock lever 2. By lowering of the lock lever 2, the lower fixed frame 6 is applied toward an upper fixed frame 4 to surely fix the tile. Further, a stopper 10 is provided to be adjusted so that by lowering of the lock lever 2, the fulcrum 8 is positioned below a line A-A connecting the fulcrum 7 and the fulcrum 9, and at that position, a pin of the double lock is jumped out.
