Patent ID: 7648116

Claim:
In an apparatus for absorbing vibrations of components of heavy construction equipment which is installed in mounting components of heavy construction equipment, the apparatus including a hand rail 1 having a work mirror mounting part 5 formed in the hand rail 1 , a work mirror 2 including a mirror holder 4 , a fixing bar 3 having a fixing part 3 a for fixing the work mirror 2 with the work minor mounting part 5 of the hand rail 1 , and a vibration part 3 b for attaching the mirror holder 4 adjacent to an end of the fixing bar 3 , the apparatus further comprising: an elastic support ring which has a tightening part at both ends of a longitudinally extended body for thereby absorbing and decreasing vibrations transferred from heavy construction equipment to components by connecting and fixing between the fixing part and the vibration part as the elastic support ring is tightened, wherein the elastic support ring includes one of the tightening parts formed at one end of the support ring for contacting, and fixed with an outer surface of the fixing part, and which has a hole and is integrated with the support ring, and the other of the tightening parts formed at the other end of the support ring for attaching with an outer surface of the vibration part and which has a hole opened for being attached at the outer surface of the vibration part adjacent to the mirror holder with a fixing member within a certain amount of tightening range.
