Abstract

The present invention relates to a low maintenance counter weight structure for heavy equipment. In a vehicle body (1) having a floor mounted engine (2), the rear mounted counter weight (3) comprises: first counter weight (5) and second counter weight (6) separately facing engine (2) or the periphery of the engine, wherein each of the first and second counter weights (5, 6) is mounted on either side of the rear part of body (1) by means of connection part (7) to open from or close to body (1), and each of said first and second counter weights (5, 6) is secured to or released from body (1) by means of unlocking part (8). Therefore, when the engine or any peripheral portion of the engine undergoes maintenance, specific work can be performed conveniently by shifting the first and second counter weights around the vehicle body with respect to relevant connection parts without separating the counter weights from the vehicle body.
