3.The main shuchural features of the new electric single-girder overhead travelling crane presented in this paper is as follows: Using a special gisder section to provide simple production technology and light weight; dopting hinged connection at one end between main glrders and end carrages instead of the rigid connection at both ends, eliminating the three-point supporting problem with the crane and thus improving the travelling perfomance; extending crane wheels life contributed to the combination of no-flange crane wheels and horizontal rollers.
