To provide a brake control device which can inhibit a brake response time from increasing when rapid brake operation is conducted, and to provide a crane including the brake control device.SOLUTION: A brake control device 10 includes: a hydraulic pump 22; a brake unit 6 which generates brake force exerted on a winch drum 11; an operation device 7 to which brake operation is provided; an electromagnetic proportional pressure reduction valve 2 which opens or closes so that a pressure of working fluid to be supplied to the brake unit 6 can be adjusted according to a control amount of the brake operation; selector valves 1, 12 disposed between the hydraulic pump 22 and the brake unit 6; and a controller 4 which switches the selector valves 1, 12 so that the brake unit 6 detours the electromagnetic proportional pressure reduction valve 2 and is connected to the hydraulic pump 22 when conditions of determination for determining that rapid brake operation is provided to the operation device are met.SELECTED DRAWING: Figure 2

    【課題】急ブレーキ操作が行われたときにブレーキ応答時間が長くなることを抑制することが可能なブレーキ制御装置及びこれを備えたクレーンを提供する。【解決手段】ブレーキ制御装置10は、油圧ポンプ22と、ウインチドラム11に対するブレーキ力を発生させるブレーキユニット6と、ブレーキ操作が与えられる操作装置7と、ブレーキ操作の操作量に応じてブレーキユニット6に供給される作動油の圧力が調節されるように開閉する電磁比例減圧弁2と、油圧ポンプ22とブレーキユニット6との間に介在する切替弁1,12と、操作装置に急ブレーキ操作が与えられたことを判定する判定条件が満たされた場合にブレーキユニット6が電磁比例減圧弁2を迂回して油圧ポンプ22に接続されるように切替弁1,12を切り替えるコントローラ4と、を備える。【選択図】図2
