1对重运行区域刚性隔障设置的要求GB7588-2003标准规定:“对重(或平衡重)的运行区域应采用刚性隔障防护,该隔障从电梯底坑地面上不大于0.3m处向上延伸到至少2.5m的高度。其宽度应至少等于对重(或平衡重)宽度两边各加0.10m。”显然,该条规定对于未设补偿绳(或链)的电梯来说是很容易满足要求的,但是对于设有补偿绳(或链)的电梯,如果防护隔障从电梯底坑地面上不大于0.3m处开始延伸,那么该隔障必然会影响补偿
1 pairs of heavy running zone rigid barrier set requirements GB7588-2003 standard states: “counterweight (or balance weight) of the operational area should be rigid barrier protection, the barrier from the elevator pit on the ground not more than 0.3m Up to a height of at least 2.5 m and its width shall be at least equal to 0.10 m on both sides of the width of the counterweight (or counterweight). ”Obviously, this provision is true for elevators without compensating ropes (or chains) It is easy to meet the requirements, but for elevators with compensating ropes (or chains), the barrier will inevitably affect the compensation if the barrier extends from no more than 0.3 m above the ground of the elevator pit
