cylindrical drum with the same length whereas the cylindrical drum diameter is identical to the average of the extreme diameters of the frustoconical drum 1 for a given lifting height both have the same cable length storage capacity however the approach minimal height of the hook 3 to the main rotation axis i of the frustoconical drum 1 has a comparatively lower value corresponding to the difference between the minimum diameter of the frustoconical drum 1 and the diameter of the equivalent traditional cylindrical drum by tilting the main rotation axis i of the frustoconical drum 1 with an a value in relation to the reference axis of the upper sheave 2 contained in the plane ii the frustoconical drum winch for lifting loads with hook reduced approximation lifting height is also characterized by proportionally reducing the resistant load torque by the ratio between the diameter of the frustoconical drum section 1 orthogonal to the main axis i concurrent with the exit point of the cable 5 and the maximum diameter of the frustoconical drum 1 end top applied to axis iii of the drive motor 4 the resistant load torque applied to the axis iii is maximum when the cable 5 is completely unwound corresponding to the load suspended from the lower lift point its value is equal to the force applied by the load to the cable 5 multiplied by the distance between the drive motor 4 axis iii and the cable 5 contact point with the frustoconical drum 1 coincident with the alignment.
