To provide a derailment/falling prevention device capable of preventing damaging of a machine or a facility while preventing derailment.SOLUTION: A derailment/falling prevention device 10 of a machine traveling by a wheel 3 comprises: a contact member 12 having a tip set on the lateral side of the traveling route of the wheel; and an absorption part 15 which absorbs a force applied to the contact member 12 along the rotational axis direction of the wheel 3. The movement of the machine can be limited by the contact member 12, and thus derailment of the wheel 3 from the traveling route can be prevented. Further, an impact force when the contact member 12 comes into contact with the traveling route can be absorbed by the absorption part 15, and thus damaging of the traveling route, the contact member 12, and the machine caused by the impact force can be prevented.SELECTED DRAWING: Figure 1
【課題】脱輪を防止しつつ機械や設備の損傷を防止できる脱輪・落下防止装置を提供する。【解決手段】車輪3によって走行する機械の脱輪・落下防止装置10であって、脱輪・落下防止装置10が、先端が車輪の走行径路の側方に配置された接触部材12と、接触部材12に対して車輪3の回転軸方向に沿って加わる力を吸収する吸収部15と、を備えている。接触部材12によって機械の移動を制限できるので、車輪3が走行径路から脱輪することを防止できる。しかも、接触部材12と走行径路が接触した際の衝撃力を吸収部15で吸収できるので、衝撃力に起因する走行径路や接触部材12、機械の損傷を防止できる。【選択図】図1
