The winding gear trolley comprises end supports (3), a lifting and displacement mechanism (4, 5) and a lifting drum (1). A support beam (6) has been fixed so as to be able to pivot at the end supports (3) and is located directly beside the lifting drum (1) and parallel to it. The end supports are rigidly connected together by the non-rotary shaft (2) carrying, in such a way as to be able to turn, the lifting drum (1) and a pair of carrying wheels (7). <IMAGE>
