The invention provides a trolley traction device and a quay crane, and relates to the technical field of hoisting. The trolley traction device comprises a trolley running winding drum, a first bend wheel assembly, a second bend wheel assembly, a first steering wheel assembly and a second steering wheel assembly. A first bend wheel assembly and a second bend wheel assembly are arranged on the sea side of a trolley operation winding drum, so that a first traction rope and a second traction rope are output from the sea side of the trolley operation winding drum, and the trolley operation winding drum can be arranged on the upper portion of a machine room bottom frame through the arrangement mode; a sunken chassis does not need to be arranged at the bottom of the machine room chassis, so that the manufacturing difficulty of the machine room chassis is simplified; due to the fact that the trolley running winding drum is arranged on the upper portion of the machine room chassis, guardrails do not need to be arranged around the trolley running winding drum, the space utilization rate of the machine room is effectively improved, the size of the machine room can be reduced, and the production cost of the machine room is reduced.

    本发明提供一种小车牵引装置及岸桥,涉及起重技术领域。小车牵引装置包括小车运行卷筒、第一改向轮组件、第二改向轮组件、第一转向轮组件和第二转向轮组件。通过在小车运行卷筒的海测分别设置第一改向轮组件和第二改向轮组件,使得第一牵引绳和第二牵引绳均从小车运行卷筒的海测输出,采用这样的设置方式可使小车运行卷筒设置于机器房底架的上部,无需在机器房底架的底部设置下沉式底架,简化了机器房底架的制造难度;由于将小车运行卷筒设置于机器房底架的上部之后,无需在小车运行卷筒的周围设置护栏,有效提高了机器房的空间利用率,这样可以减小机器房的体积,降低机器房的生产成本。
