To provide a lamination type counterweight capable of eliminating fine adjustment work of positioning when stacking weights, and as a result, capable of alleviating high place work and work close to the weights.SOLUTION: A lamination type counterweight 101 is a lamination type counterweight mounted on a work machine and it includes a plurality of weights 1-4 stacked in the vertical direction. Part of or the entire upper surface of each of the weights 1-4 is a convex (or concave) upper side tapered surface 5 inclining with respect to the horizontal direction. Also, part of or the entire lower surface of each of the weights 2-4 is a concave (or convex) lower side tapered surface inclining with respect to the horizontal direction and fitted in the upper side tapered surface 5 of one of the weights 1-3 stacked one stage below.SELECTED DRAWING: Figure 1

    【課題】ウエイトを積み上げる際に、その位置決めの微調整作業を不要とすることができ、その結果、高所作業やウエイトに近づいての作業を軽減することができる積層型カウンタウエイトを提供すること。【解決手段】積層型カウンタウエイト101は、作業機械に搭載される積層型カウンタウエイトであって、鉛直方向に積み上げられる複数のウエイト1〜4を備える。ウエイト1〜4の上面の一部または全部が、凸状(または凹状)の水平方向に対して傾斜する上側テーパ面5とされる。また、ウエイト2〜4の下面の一部または全部が、1段下に積まれるウエイト1〜3の上側テーパ面5に嵌まり込む、凹状(または凸状)の水平方向に対して傾斜する下側テーパ面とされる。【選択図】図1
