Use of the spreader bar with 2 (3) suction plates
When using the crossbar with 2 suction plates only suction plates of the same design (carrying capacity, dimensions and
form) may be used!
The suction plates must always have the same distance (A) to the vertical centre axis of the crossbar (see figure 1).
Unequal positioning of the suction plates is not permitted (see figure 2)!
Take care that the load (stone slab) hangs always horizontal .
For special spreader bars where 3 suction plates are permitted, they must be positioned in the same way (see Fig. 3).
