To provide a method for preventing damage of pin actuator assembly for a telescopic boom.SOLUTION: An electric assembly includes a locking head having a base, an operation plate operatively connected to the base, and one or more cylinder pins and/or one or more section lock arms which can move in response to the movement of the operation plate with respect to the base. The pin actuator assembly also includes an actuator that is operatively connected to the operation plate so as to move the operation plate with respect to the base. The pin actuator assembly further includes an operation mitigating part 16 having a rod 38 that is movable with respect to a housing 46 and operatively connected to the actuator, a first energization member 40 connected to between the rod 38 and the housing 46, and a second energization member 44 connected to between the rod and the housing.SELECTED DRAWING: Figure 7

    【課題】伸縮ブームのためのピンアクチュエータアセンブリの損傷を防ぐ方法の提供。【解決手段】ベース、ベースに動作可能に連結された操作プレート、ベースに対する操作プレートの動きに応じて移動可能な1つ以上のシリンダーピン及び/又は1つ以上のセクションロックアームを有するロッキングヘッドを含む。ピンアクチュエータアセンブリはまた、操作プレートに動作可能に連結され、ベースに対して操作プレートを動かすようにされたアクチュエータを含む。ピンアクチュエータアセンブリは更に、ハウジング46に対して移動可能でありアクチュエータに動作可能に連結されたロッド38、ロッド38とハウジング46との間に連結された第1の付勢部材40、及びロッドとハウジングとの間に連結された第2の付勢部材44を有する動作緩和部16を含む。【選択図】図7
