To provide an operation cradle for a heavy machine capable of easily forming a support surface to be horizontal or approximately horizontal on a slop surface.SOLUTION: An operation cradle 1 for a heavy machine is provided with a body part 11 and a load dispersion plate 12. The body part 11 comprises an upper surface 11t forming a support surface SF and a slop bottom surface 11b placed to face a slop surface IS with an angle A corresponding to a slop angle α of the slop surface IS when the heavy machine HM is installed on the slop surface IS. The load dispersion plate 12 has a tip part 12f projecting from a tip 11f of the body part 11 and placed on the slop surface ISm and has elasticity bending along the upper surface 11t of the body part 11 and the slop surface IS under the load of the heavy machine HM. The upper surface 11t of the body part 11 has an upper surface tip part 11tf and an upper surface rear part 11tr. The upper surface tip part 11tf is inclined relative to the upper surface rear part 11tr such that an angle between the upper surface tip part 11tf and the slop surface IS is larger than that between the upper rear part 11tr and the slope surface IS.SELECTED DRAWING: Figure 1 【課題】傾斜面上に水平または水平に近い支持面を容易に形成可能な重機用作業架台を提供する。【解決手段】重機用作業架台１は、本体部１１と、荷重分散板１２とを備える。本体部１１は、重機ＨＭが傾斜面ＩＳの上に設置されたときに、支持面ＳＦを形成する上面１１ｔと、傾斜面ＩＳの傾斜角αに対応する角度Ａで斜面ＩＳに対向配置される傾斜底面１１ｂと、を有している。荷重分散板１２は、本体部１１の先端１１ｆから突出して傾斜面ＩＳの上に配置される先端部１２ｆを有し、かつ重機ＨＭの荷重を受けて本体部１１の上面１１ｔおよび傾斜面ＩＳに沿ってたわむ弾性を有している。本体部１１の上面１１ｔは、上面先端部１１ｔｆと、上面後方部１１ｔｒと、を有している。上面先端部１１ｔｆと傾斜面ＩＳとの間の角が、上面後方部１１ｔｒと傾斜面ＩＳとの間の角よりも大きくなるように、上面先端部１１ｔｆが上面後方部１１ｔｒに対して傾斜している。【選択図】図１
