  Subsequently, the worker P climbs up to the scaffold 30 attached to the frame body 20 installed at the end in the vehicle width direction using a ladder or the like (not shown), and stands on the scaffold 30 while holding the safety belt supporting device. The base 51A of the 50A is fitted to the corner 20a of the frame 20 from outside the frame 20. In the externally fitted state, the bottom surface of the upper surface portion 51a of the base portion 51A abuts on the upper surface of the upper side portion 21 of the frame body 20, and the inner side surface of the side surface portion 51d of the base portion 51A is 23 abuts on the outer surface. Subsequently, the operator P sequentially inserts the bridging member 62, which is a bolt, into the hole 61a of the outer surface 51b and the hole 61b of the inner surface 51c of the base 51A, and screws the nut 61c.

  Subsequently, the worker P attaches one end of the safety band 40 to his / her waist and locks the hook 41 at the other end of the safety band 40 with the ring portion 52b of the safety band support device 50A.

  Subsequently, the worker P installs the three frames 20 on the carrier 11 of the vehicle 10.

  Subsequently, a loading operation for loading the panel A on the carrier 11 is performed by a crane truck. When the panel A lifted by the crane truck is loaded on the carrier 11, the operator P removes the sling attached to the panel A from the panel A.

  After the loading operation of the panel A is completed, the scaffold 30 and the safety belt support device 50 are removed from the frame 20.

  Note that the scaffold 30, the safety belt 40, and the safety belt supporting device 50A are similarly used when performing the work of lowering the panel A from the carrier 11 of the vehicle 10 at the house building site.
