Title
(EN) SAFETY DEVICE OF WORKING MACHINE HAVING ELEVATING CAB
(JA) 昇降式キャブを有する作業機械の安全装置
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a safety device of a working machine with an elevating cab, which can be suitably applied to various types of working machines each comprising the elevating cab, which can call an operator's attention to the opening of a cab door when the cab is in an elevated position, and which can prevent the operator from falling from the cab.

SOLUTION: Door lock means is provided separately from lock means as standard equipment in a cab, and a lock detection sensor detects the state of being locked by the door lock means. In the case where the state of being locked by the door lock means is released when the cab is in a position higher than a loadable/unloadable height position, alarm means using a warning lamp and the like provides notification of an alarm. This can prevent an operator from falling from the cab in the high position.

【課題】 昇降式キャブを備えた各種作業機械に対して好適に適用することができ、キャブが上昇位置にあるときにキャブのドアが開けられたことを運転者に注意喚起でき、キャブからの転落を防止できる昇降式キャブを有する作業機械の安全装置を提供する。
【解決手段】 キャブ内に標準装備のロック手段とは別にドアロック手段を設け、ドアロック手段によるロック状態をロック検出センサにより検出する。キャブが乗降可能高さ位置よりも高い位置に居たときにドアロック手段によるロック状態が解除されると、警報灯等を用いた警報手段により警報を報知する。これにより、高い位置にあるキャブからの転落を防止できる。
