Abstract
A wheeled crane constructed in such a manner that when the crane is to be transported on a road, the whole of the crane is lifted upward on a front side thereof, allowing front wheels 4 of a lower travel body 1 float from a road surface, and a coupling frame 19 provided at a front end portion of the lower travel body 1 is coupled to a coupler 23 of a tractor T, thereby permitting the crane to travel by itself as a semi-trailer while ensuring a long wheel base, as well as a method for transporting the wheeled crane, and a coupling type vehicle.
Claims18
A method for transporting a wheeled crane, said wheeled crane comprising:
- a lower travel body;
- an upper rotating structure mounted rotatably on said lower travel body;
- a boom provided in said rotatable superstructure so as to be capable of rise and fall;
- a cabin provided for both crane work and traveling in said rotatable superstructure;
- a travel body frame provided in said lower travel body;
- a coupling means provided in said travel body frame;
- axles provided at least in front and rear positions of said travel body frame and on both sides of the travel body frame;
- and
- wheels for self-traveling of the crane, said wheels being provided on both sides of said axles,
- said method comprising coupling said crane to a tractor through said coupling means and a coupler of the tractor uncouplably and in a relatively rotatable state about a vertical axis, centered on said coupler, while lifting the whole of the crane with respect to said coupler, allowing the tractor-side wheels out of the front and rear both-side wheels of the crane to float, thereby allowing a crane load to be partially borne by the tractor, and in this coupled state, towing and transporting the crane by the tractor.

A method for transporting a wheeled crane, said wheeled crane comprising:
- a lower travel body;
- an upper rotating structure mounted rotatably on said lower travel body;
- a boom provided in said rotatable superstructure so as to be capable of rise and fall;
- a cabin provided for both crane work and traveling in said rotatable superstructure;
- a travel body frame provided in said lower travel body;
- a coupling means provided in said travel body frame;
- axles provided at least in front and rear positions of said travel body frame and on both sides of the travel body frame;
- and
- wheels for self-traveling of the crane, said wheels being provided on both sides of said axles,
- said method comprising coupling said crane to a tractor through said coupling means and a coupler of the tractor uncouplably and in a relatively rotatable state about a vertical axis, centered on said coupler, while lifting the whole of the crane wit respect to said coupler in an upwardly tilted state on a front side of the crane, allowing said boom to become substantially horizontal, said boom being adapted to tilt downward on a front side thereof in a grounded state of all said wheels and in a maximum fallen state of the boom, allowing front wheels of the crane to float from a road surface, thereby allowing a crane load to be partially borne by the tractor, and in this coupled state, towing and transporting the crane on the road by the tractor.

- a boom provided in said rotatable superstructure so as to be capable of rise and fall;
- a cabin provided for both crane work and traveling in said rotatable superstructure;
- a travel body frame provided in said lower travel body;
- a tractor coupling means for coupling a tractor and the crane with each other, said tractor coupling means being provided in said travel body frame;
- axles provided at least in front and rear positions of said travel body frame and on both sides of the travel body frame;
- wheels for self-traveling of the crane, said wheels being provided on both sides of said axles;
- and
- said tractor coupled to the crane through said coupling means,
- said wheeled crane being constructed in such a manner that when said lower travel body is coupled to a coupler of the tractor, the whole of the crane is lifted so that the tractor-side wheels out of said wheels float from a road surface, thereby allowing a crane load to be borne partially by the tractor, and in this state the crane can rotate relatively about a vertical axis, centered on said coupler.
