こともできるため、別に足場を組む必要もなくなる。When using the trolley shown in FIGS. 5 to 8, the support frame 4 can be raised and lowered by expanding and contracting the lifting jack 18, so that it can support free-rotating propellers 2 of all sizes from small diameters to large diameters. In addition, it is possible to eliminate the need for rehanging the idling propeller 2 from the cart to the chain block 17 as shown in FIG. Furthermore, by telescopically operating the vertical jack 27, the propeller pedestal 3 can be vertically displaced on the left and right sides individually, so the rotation adjustment and inclination adjustment of the free-rotating propeller 2 on the propeller pedestal 3 can be made easily. The centering of the idling propeller 2 can be performed using the truck itself. Therefore, it is possible to eliminate the need for attaching and removing the chain block 17 shown in FIG. Compared to the case where the installation work of the idling propeller 2 is carried out by the user, the work can be carried out more efficiently. That is, since there is no need to attach the hanging ring 16 to the hull 13, there is no need to perform any work related to installation, welding, degassing during removal, blowing, grinding, painting repair of the inner and outer surfaces, etc., and the weight is also reduced. There is no need to temporarily install or remove a certain chain block (for example, a 30-chain chain block), and the positioning of the free-rotating propeller 2 can be done easily without any effort.Furthermore, the trolley can also be used as a scaffolding device. This eliminates the need for separate scaffolding.

Of course, various changes can be made without departing from the gist of the invention.

By adopting a series of work processes, it is possible to efficiently install the idling propeller, and the cart used for the installation work of the idling propeller can be fitted with a wide movable cart body and the diameter of the idling propeller. By having a structure having a support pedestal with a height corresponding to the above, it is possible to stably transport an idling propeller supported vertically. By being equipped with a swivel device that adjusts the rotation of the idling propeller and a tilt adjustment device that adjusts the inclination of the idling propeller, the work from transporting the idling propeller to mounting it on the shaft can be easily done with just the trolley. It can be done with excellent results.
