PROBLEM TO BE SOLVED: To prevent contact of a spreader or a container with a vehicle body or a boom due to misoperation in a reach stacker.SOLUTION: An interlock controller as a safety device is provided on a reach stacker comprising a boom 18 which is so provided on a vehicle body 11 as to be capable of being corrugated and telescopically moved, and a spreader 19 which is provided at a tip of the boom 18 and holds containers 20S, 20L. The interlock controller determines an emergency stop position at which there is possibility that the spreader 19 and the containers 20S, 20L approach and contact the vehicle body 11 and the boom 18 on the basis of a determination signal detected by a sensor for an angle of inclination and a length of the boom 18 and motion of a revolution angle or the like of the spreader 19, and emergently stops a drive unit during operation when reaching the emergency stop position.SELECTED DRAWING: Figure 2

    【課題】リーチスタッカにおいて、誤操作などによる、スプレッダまたはコンテナの車体またはブームへの接触を防止する。【解決手段】車体11に起伏自在、伸縮自在に設けられたブーム18と、ブーム18の先端部に設けられてコンテナ20S,20Lを保持するスプレッダ19とを具備したリーチスタッカに、安全装置であるインターロックコントローラを設けたものである。インターロックコントローラは、ブーム18の傾斜角および長さと、スプレッダ19の旋回角などの動作をそれぞれ検出器に検出された判断信号に基づいて、スプレッダ19やコンテナ20S,20Lが車体11やブーム18に接近し、接触するおそれがある非常停止位置を判断し、非常停止位置に達すると動作中の駆動装置を非常停止する。【選択図】図2
