随着我国建筑业的飞速发展,对建筑施工机械化程度要求越来越高,尤其对载人的垂直运输机械的安全可靠性要求更加严格;因此,建筑机械的更新、安全系统的完善,成为设计制造中至关重要的问题。安全装置是产品成败的关键。 With the rapid development of China’s construction industry, the degree of mechanization of building construction is becoming more and more demanding, especially for the safety and reliability requirements of manned vertical transportation machinery; therefore, the updating of construction machinery and the improvement of safety systems become a design. The key issue in manufacturing. Safety devices are the key to product success or failure.
