品名：聚氨酯緩沖器

作用：當運行機械位置限制器或制動裝置發生故障時，由于慣性的原因，運行到終點的起重機或小車，將在運行終點與設置的止擋體相撞。設置緩沖器的目的就是吸收起重機或起重小車的運行功能，以減緩沖擊。緩沖器設置在起重機或者起重小車與止擋體相碰撞的位置。在同一軌道。

應用：聚氨酯泡沫塑料緩沖器吸收能量大，緩沖性能好，耐油、耐老化、耐酸、耐腐蝕、耐高溫低溫，絕緣又防爆，相對密度小兒而輕，機構簡單、價格低、無噪音、無火花、安裝維修方便、使用壽命長等特點。所以在國際上已經普遍采用，在一般起重機上，可替代橡膠和彈簧緩沖器，在防爆場所更值得推廣。

Item description: polyurethane buffer

Function: when running mechanical position limiter or brake failure occurs, because of inertia, run to the end of the crane or trolley, set in running the end and the end of body collision. The purpose of setting buffer is absorbed a crane or lifting the car running function, to slow down the impact. Buffer is set in a crane or lifting the car and stop the location of the collision. Applications in the same orbit: polyurethane foam buffer energy absorption, cushioning performance is good, oil resistance, ageing resistance, acid resistance, corrosion resistance, high temperature and low temperature resistance, insulation and explosion-proof, relative density and pediatrics is light, simple structure, low price, no noise, no spark, easy installation and maintenance, long service life, etc. So has been widely used in the world, on the general crane, alternative rubber and spring buffers, more worthy of popularization in explosion-proof places.
