Description

The convenient vehicle block selecting automatic traveling crane system of operation and working method
Technical field
The present invention relates to a kind of vehicles, and in particular to a kind of convenient vehicle block selecting automatic traveling crane system of operation and work side Method.
Background technology
Vehicle generally first selects forward gear, then releases stopping brake in normally travel state when driver is open to traffic It steps on the gas again, when that need to stop, throttle can be unclamped and selection and is braked at neutral gear, for need to often convert operating location and not With the distance between operating location and shorter working truck since its operating range is very short, and needs frequent during operation Parking continually operates throttle, gear and braking for driver, and operation is very inconvenient, therefore designing one kind can be just Normal transport condition switched over job state and in job state block selecting can automatic traveling crane, easy to operate vehicle block selecting Automatic traveling crane system is very necessary.
Invention content
The object of the present invention is to provide one kind to be switched over and in job state in normally travel state and job state When block selecting when can automatic traveling crane, easy to operate vehicle block selecting automatic traveling crane system.
