由于建筑工地有很多潜在危险,欧美国家普遍强制实施安全规范,以确保工程机械车辆及驾驶员有足够的安全措施,从而降低工程机械车辆在施工结构中因为损坏车辆结构而导致操作员遭遇意外的风险。因此,绝大部分工程车辆的前部以及后部都会设有逃生舱门,一旦紧急情况发生,操作员能够以最快速度离开驾驶室,保障自身的安全。 Because there are many potential dangers in the construction site, European and American countries generally enforce safety regulations to ensure that construction machinery vehicles and drivers have adequate safety measures to reduce accidents caused by the operator’s accidental damage to the construction machinery due to damage to the vehicle structure risk. Therefore, the vast majority of engineering vehicles will be equipped with escape hatches on the front and rear of the vehicle. Once an emergency occurs, the operator can leave the cab at the fastest speed to ensure his own safety.
