PROBLEM TO BE SOLVED: To provide an emergency brake system for a cargo handling machine, that controls braking when power failure occurs and prevents sudden deceleration by adjusting deceleration.SOLUTION: Provided is an emergency brake system for a cargo handling machine, that includes brakes (a travel brake 20 and a swing brake 23) for permitting operation of object equipment (a travel device 6 and a swing device 9), in an open state during electrification, and on the other hand, for executing braking of the object equipment (the travel device 6 and the swing device 9), in a closed state during electrification failure. The emergency brake system is equipped with uninterruptible power supply devices 30 and 32 for electrifying at least a part among the brakes (the travel brake 20 and the swing brake 23) when power failure occurs, and is configured to control braking of the object equipment (the travel device 6 and the swing device 9) by controlling opening and closing of the brakes (the travel brake 20 and the swing brake 23).SELECTED DRAWING: Figure 1
【課題】停電時の制動を制御し、減速度を調整して急減速を防止し得る荷役機械の非常ブレーキシステムを提供する。【解決手段】通電時には開状態で対象機器(走行装置6、旋回装置9)の動作を許容する一方、通電停止時には閉状態となって前記対象機器(走行装置6、旋回装置9)の制動を実行するブレーキ(走行ブレーキ20、旋回ブレーキ23)を備えた荷役機械の非常ブレーキシステムに関し、停電時に前記ブレーキ(走行ブレーキ20、旋回ブレーキ23)のうち少なくとも一部に通電を行う無停電電源装置30,32を備え、前記ブレーキ(走行ブレーキ20、旋回ブレーキ23)の開閉を制御して前記対象機器(走行装置6、旋回装置9)の制動を制御するよう構成する。【選択図】図1
