は操作機構。In a crane configured to fix a hook driven by a winch to a hook hook while traveling, a switching valve assembly having a switching valve for switching an oil path to the winch driving oil motor has a low pressure in its return oil path. A relief valve and another switching valve for switching the oil path to the hydraulic motor for driving the winch are integrally connected to the switching valve assembly, and the winch is driven by operating the other switching valve to hook the winch. The hook hook is an operating mechanism that is configured to do so.
