PURPOSE:To make size in a longitudinal direction of an outer post's upper half part diminishable as well as to make the outer post so as to keep out of the way in time of material handling, by leading a rope into a rope guide being set up inside a post support end, and mooring it to a lower end of a lift bracket. CONSTITUTION:An inner post 4 is slidably installed in an outer post 3 erected at both sides of a rear end of a deck 2. A rear gate 6 is attached to a lift bracket 5 being slidably installed in the inner post 4, while the rear gate 6 is made to go up and down by means of a hydraulic cylinder 9 inside a posy support 8 via ropes 11 and 12. On the other hand, these ropes 11 and 12 are led into each of pulleys 14, 14a, 16 and 16a installed inside an end of the post support 8, causing them to deflect downward, and moored to an anchor 18a. A sliding guide slit 23 of the anchor 18a is formed in a front wall's lower half part of the inner post 4 and sitting astride the slit 23, a U-shaped sectional subpost 24 is welded for reinforcement. |
