PURPOSE:To perform transportation and loading/unloading of heavy duty machine more easily and safety by arranging mechanisms for interlocking the fixing metal slidable smoothly in guide mechanism with a hydraulic cylinder at four positions on the rear body. CONSTITUTION:The upper frame of truck chassis is bored to secure a hydraulic cylinder 2. Then two C-shaped rails 3 are secured in parallel on the extended line of the cylinder 2 through such gap as approximately same with the diameter of the foot section 7 of caterpillar fixing metal 7. The metal 4 for fixing the head section of hydraulic cylinder will slide in two rails 3 while a hole for inserting the foot section 7 is made in the center. A gap 9 for sliding the neck section 6 of caterpillar fixing metal is made through the rear body board on the reciprocal stroke of said metal 4. Said systems are arranged as a set in front and rear of the rear body and two sets are arranged symmetrically while shifting by the diameter of the cylinder 2. |
