防(fang)撞(zhuang)(zhuang)緩(huan)(huan)(huan)(huan)沖車(che)(che)的(de)(de)作用：停在施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)區(qu)域的(de)(de)后(hou)方(fang)(fang)，如(ru)果有車(che)(che)輛沒看到施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)區(qu)域追撞(zhuang)(zhuang)過來，防(fang)撞(zhuang)(zhuang)緩(huan)(huan)(huan)(huan)沖車(che)(che)的(de)(de)緩(huan)(huan)(huan)(huan)沖墊就可以吸(xi)收(shou)撞(zhuang)(zhuang)擊能量，保障前方(fang)(fang)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)人(ren)(ren)員(yuan)的(de)(de)安全。防(fang)撞(zhuang)(zhuang)緩(huan)(huan)(huan)(huan)沖車(che)(che)主要用于(yu)高速公路施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)、隧道(dao)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)、公路施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)等工(gong)(gong)(gong)程時(shi)，可以降(jiang)低施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)車(che)(che)輛、養護(hu)人(ren)(ren)員(yuan)和(he)(he)處理事故(gu)的(de)(de)交警的(de)(de)安全風險。防(fang)撞(zhuang)(zhuang)緩(huan)(huan)(huan)(huan)沖吸(xi)能模塊主要由車(che)(che)載防(fang)撞(zhuang)(zhuang)緩(huan)(huan)(huan)(huan)沖墊和(he)(he)導向標志架組成，充當施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)作業車(che)(che)輛后(hou)方(fang)(fang)的(de)(de)緩(huan)(huan)(huan)(huan)沖衛士(shi)。如(ru)若發(fa)生(sheng)追尾事故(gu)，能夠在肇(zhao)事車(che)(che)輛和(he)(he)前方(fang)(fang)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)作業區(qu)域之(zhi)間構(gou)建一個緩(huan)(huan)(huan)(huan)沖區(qu)域，通過機具結構(gou)變形吸(xi)收(shou)撞(zhuang)(zhuang)擊的(de)(de)能量，較大限(xian)度(du)地降(jiang)低被保護(hu)人(ren)(ren)員(yuan)及(ji)設備(bei)遭到碰撞(zhuang)(zhuang)的(de)(de)幾率。
