CONCRETE SUPPLY DISTRIBUTOR

To provide a concrete supply distributor which includes a boom unit mounted on a mast unit and comprising a boom row consisting of multiple booms arranged in series with each other and connected to each other bendably and swingably, and boom supports attached to the top of the mast unit and pivotably supporting derrickably and turnably the boom at the most base end side in the boom row, and which is capable of quickly and easily replenishing grease to the lubrication parts of multiple booms in the boom row even with the boom row mounted on the boom support so as to reduce the work time and man-hours.SOLUTION: The concrete supply distributor includes: a grease injection part Gi provided in boom support BS and a distribution valve Vd connected to the grease injection part; and multiple grease tubes GL1-GL4 that are connected in parallel to the grease injection part Gi via the distribution valve Vd extending to respective multiple lubricated parts of multiple booms B1-B4 of the boom row BT. The multiple grease tubes GL1-GL4 extend along the boom row BT and are fixed to the boom row BT.SELECTED DRAWING: Figure 12 【課題】マスト装置上に搭載されるブーム装置が、互いに直列に配列され且つ相互間が屈折揺動可能に連結される複数のブームよりなるブーム列と、マスト装置の上部に取付けられてブーム列における最も基端側のブームを起伏可能に軸支するブーム支持台とを有するコンクリート供給用デストリビュータにおいて、ブーム列をブーム支持台上に取付けたままでも、ブーム列における複数のブームの被潤滑部に対しグリスを迅速且つ容易に補給可能として作業時間の短縮や作業工数の低減を図る。【解決手段】ブーム支持台ＢＳに設けられるグリス注入部Ｇｉ及び該グリス注入部に連なる分配弁Ｖｄと、グリス注入部Ｇｉに分配弁Ｖｄを介して並列に接続されてブーム列ＢＴの複数のブームＢ１～Ｂ４の被潤滑部までそれぞれ延びる複数のグリス配管ＧＬ１～ＧＬ４とを備え、その複数のグリス配管ＧＬ１～ＧＬ４は、ブーム列ＢＴに沿うように延びてブーム列ＢＴに固定される。【選択図】 図１２
