Abstract

PURPOSE: To perform outward extension with sufficient tilt angle, by fixing the upper part of expansion cylinder to the chassis and providing a hydraulic cylinder which swingably supports the tip of piston rod of the expansion cylinder to the chanssis.
CONSTITUTION: The expansion cylinder 10 consists of an outer cylinder 11 fixed at one end to the chassis 6, and an inner cylinder 12 slidably fitted in the outer cylinder 11. A longitudinal hole 33 is prvided in thecentral part of the inner cylinder 12. A pin 21 is inserted in the longitudinal hole from the outr cylinder 12. The end of the piston rod 15 of the hydraulic cylinder 14 is fitted to the chassis 6 outside the butt of the outer cylinder. The hydraulic cylinder 14 is located along the outer cylinder 11. A bracket 8 for a cylinder tube 16 can be coupled to a bracket 13 at the tip of the inner cylinder 12 by a pin 21 after holes 19, 20 of these brackets are matched with each other. The cylinder tube 16 and an inner cylinder bracket 13 are coupled to each other by shafts 22, 23 and a link 24 so that the outsard extension can be performed with sufficient tile angle
