Abstract

Improvements introduced in hoisting arrow cranes, which include a mast on top of which the foot of a telescopic arrow is articulated, in which the tip of this same arrow slides, while a device with a cable passing through a prop allows lifting more or less the arrow, and is characterized in that the elongation of the telescopic arrow is controlled by a cable arranged between the tip and the foot of the arrow, while the collection of this telescopic arrow is controlled by a collection cable arranged between the foot and the tip, these two cables as well as the arrow hoisting cable coiled in three juxtaposed drums of the same winch that actuates them simultaneously and synchronously to automatically vary the length of the telescopic arrow as its elevation angle varies.
