Abstract

Improvements in the mechanism of rotating cranes characterized by comprising in combination a traction base; a crane body held rotatable in the base mentioned; oscillation mechanisms for oscillating the body of the crane with respect to the base and comprising an oscillation shaft an oscillation pinion operable by said shaft an oscillation gear on the base which operates in combination with the oscillation pinion an engine a driven shaft driven by the motor and a set of differential gears of various speeds interspersed between the driven shaft and the oscillating shaft 1 and means for selectively driving the gears of a set of differential gears to drive the oscillating shaft at a chosen speed of several of them from the mentioned driven tree; the set of differential gears comprises gears of different gear ratios; a high-speed gear that works in combination with one of the gears of the differential assembly; a gear of reduced speed cooperating with the other gear of the differential assembly; a shaft carrying said upper and lower speed gears operable by the driven shaft of the motor and means for establishing a transmission or drive connection between the last mentioned shaft and any one of the upper or lower speed gears thereupon supported.
