きる。 In this case, the mast mount 20 is cylindrical,
Since the fitting part 26 has an inverted U-shape, the front and rear legs 27 of the fitting part 26 are guided by the receiving surface 25 of the mast mount 20, and the fitting part 26 is smoothly fitted to the mast mount 20. do. When the fitting part 26 is fitted to the mast mount 20, the long holes 24 and 28 of both correspond to each other in the front and back, so for example, insert the bolt 32 with the wedge body 31 from the front side, and insert the bolt 32 from the rear side. After inserting the wedge body 33 into the bolt 32, tighten the nut 35. Then, the legs 27 in front and behind the wedge bodies 31 and 33 are pushed down, and the fitting part 26 is connected to the mast mounting base 20.
It comes into close contact with the receiving surface 25 and can be securely fixed without wobbling.
ブレース１７の前部は適宜手段でブレース取付
台２１に固定する。 The front part of the brace 17 is fixed to the brace mounting base 21 by appropriate means.
フロントローダ１２を取外した時には、ますと
