Title: System for stabilizing railroad cranes
Inventor: IONESCU ION
IPC: B66C23/78
Filed: 2013-07-18
Abstract: The invention relates to a stabilizing system equipping a railroad crane with a capacity of minimum 80 tf in order to ensure the stability thereof during operation, both in case of being placed directly on the crane-waggon and in case of being placed on a crane-train waggon. According to the invention, the system comprises an anchoring piece (4) mounted on a base plate (1) of a stabilizing device (A) to which there is attached a traction cable (8), driven by a self-blocking mini crane (9) which comprises an electric motor (10) coupled with a reduction gear box (28), the mini crane (9) being provided with a recess (11), for being manually driven by means of a handle, wherein, for support and fastening purposes, there is provided an upper plate (14) attached in a cut-out made in the lower support of a main side bar (5) of a crane-waggon (M), on which a support bushing (15) is joined by screwing and secured against unfastening by several welding points, outwardly protected by a cover (16), fixed to the bushing (15), in the central part of the bushing (15) there being vertically positioned a bolt (17) on whose machined surfaces there are arranged a bearing (18) and a guide bushing (19), positioned to the lower side, which mainly ensures the centering and the guiding due to the contact surfaces with a bolt (17) and where the traction cable (8) has at its ends some catching loops (33) for fastening the stabilizing device (A) through some anchoring rings (i).
