Description

technical field

[0001] The invention belongs to the technical field of bridge construction, and in particular relates to a multifunctional longitudinal movement driving device for a bridge erecting machine. Background technique

[0002] At present, the driving method of the crane crane of the bridge erecting machine is mainly the motor + reducer to drive the wheels, which require the wheels to overcome the friction between the track and the bridge. This method is mainly used for the construction of bridges with small slopes. Good results. However, for bridges with a longitudinal slope of more than 3%, it is difficult to provide a suitable driving force by the adhesion between the wheels and the track. At the same time, due to the large slope, slippery phenomena often occur, especially in rainy and snowy weather. , the friction coefficient between the wheel and the track is smaller, which increases the safety risk.

[0003] For the through-hole driving method of the bridge ...
