Abstract (en)
[origin: EP0298391A1] According to the invention, the luffing gear (5) for the luffing rope (7) is combined with the mast head (1) to form a unit so that it can be assembled at the building site with a mobile crane as a self-contained unit. The luffing rope (7), coming from the luffing gear (5), runs over deflection pulleys (8) at the tip of the mast head (1), then over deflection pulleys (9) of a pulley block (9, 10) connected to the mast head (1), and finally to a fixed point (11) at the mast head. The invention serves to accelerate and facilitate the erection of building cranes. <IMAGE>
