Реферат: The system uses bent support lugs (4), laid on one or two rungs (2) and partially embracing the stringers (5). The shaft (6) connecting them is fitted with a swivelling socket (9) with a displaceable carrier arm (11). The open end of the arm may bear a two-part height-adjustable support. The shaft may have an extension with a pluggable rod, bearing a socket containing a telescopic cross rod at its top end. The system facilitates quick, easy, and secure platform mounting on ordinary ladders. The platforms may be set up single-handed and using readily transportable components.
