テレスコピック状に摺動できるよう組合せらねている。Pivot support plates 4, 5.6 are fixed to the rear and center areas of the top surface of the swivel base 3, respectively. 2.1 The left and right wi assembly V near the center of the turntable 3. The lower end of the base boom 8 of the first telescopic boom 7 is attached to the pin 1 on this shaft support plate 4.
1, and a lifting hydraulic cylinder 12 is interposed between the central lower part of the base boom 8 and the swivel base 30. This telescopic boom body 7 is a base boom 8. Medium boom 9. It consists of a tip boom 10, each having a different diameter, and is configured to be able to slide telescopically.
A shaft support plate 14 provided below one side of a flat elevator platform 13 is connected to the tip of the platform by a pin 15. The base boom 17 of the telescopic boom body 1' 6 and 20 is attached to the pivot support plate 5.6, respectively.
．． The lower ends of 21 are connected by pins 24.25, and each telescopic boom body 16.20 is connected to a respective base boom 17.21.
, consisting of middle booms 18 and 22, and front booms 19 and 23,
The diameters of the booms 17 to 19 and 21 to 23 are different, and they are combined so that they can slide telescopically.

状態を示すものである。By controlling the length of each telescopic boom body 7, 16.20 to be the same during elevation, expansion and contraction of the telescopic boom body 7, 16, 20, the quadrilateral connecting the pins 11.15, 24°26 is It is always a parallelogram, and the lifting table 13 is always held horizontally, and this horizontal state can be maintained no matter where the lifting table 13 is. Figure 3 shows the telescopic boom body 7. Fig. 4 shows the state in which the lifting platform 13 is brought closer to the ground by tilting down the elevators 6 and 2o, and Fig. 4 shows the state in which the telescopic boom body 7, 16, 20 is reduced to reduce the clarity of the elevator platform 13. This shows that.
本発明は上述の様に構成したので、簡易な構成でありな
がら昇降台を常に水平に維持することができ、ブームリ
