Abstract

Dragalina of perfected manual operation, that includes a supportive tower of some walls that separate some compartments, provided in the low part of these with distributing helmets and that supports one of the ends of an aerial feather that extends over the walls in its direction, capable of moving to sweep all compartments and holding a return cable hooked to the back of a spoon whose front part is hooked to an excavation cable, each cable being connected to a towing device and a braking device, these four devices are activated selectively by means of a pilot device operated by the dragline driver, this dragline being characterized: - because it applies automatic dragline traction and braking devices, which comprise, for each cable, a winch and a brake capable of being driven by electric means and which cooperate for this purpose with a control center comprising contactors: of which some cause the winding, unwinding and braking of the considered cable and others, associated with a boom drag device cause the movement of this to the right or to the left, - because it also applies, to constitute at least in part the piloting device, at least one manipulator that cooperates selectively, in the various positions it is capable of occupying, with a pilot box. - and in that the pilot box comprises a front digging microcontact 112, a return microcontact 113, a rear landing microcontact 116, 117, a right hand drive microcontact 114 and a left hand drive microcontact 115, these being microcontacts connected to the contactors of the control unit in order to obtain, by sensitive means, at least the different parts of an automatic cycle, automatically coordinating its components.
