Finally, after the gantry crane 500 slowly lifts the hook to enable the steel wire rope 600 to bear a slight force and bear the weight of the T-beam template 100, the gantry crane 500 slowly moves transversely to enable the T-beam template 100 to be separated from the beam body. And after the T-beam template 100 is completely separated from the beam body range, transferring the T-beam template 100 to other positions to finish the dismantling of the T-beam template 100.
Through the process, in the using process of the whole lifting appliance, the postures of the lifting appliance and the T-beam template 100 are always consistent with the working state, the positions of the T-beam template 100 and the lifting appliance do not need to be adjusted manually or by the gantry crane 500, no additional force is generated, the construction procedures are reduced, the safety of operators is ensured, and the possible damage to the T-beam template 100 and the beam body is avoided.
It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Numerous obvious variations, rearrangements and substitutions will now occur to those skilled in the art without departing from the scope of the invention. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
