品名：聚氨酯缓冲器

作用：当运行机械位置限制器或制动装置发生故障时，由于惯性的原因，运行到终点的起重机或小车，将在运行终点与设置的止挡体相撞。设置缓冲器的目的就是吸收起重机或起重小车的运行功能，以减缓冲击。缓冲器设置在起重机或者起重小车与止挡体相碰撞的位置。在同一轨道。

应用：聚氨酯泡沫塑料缓冲器吸收能量大，缓冲性能好，耐油、耐老化、耐酸、耐腐蚀、耐高温低温，绝缘又防爆，相对密度小儿而轻，机构简单、价格低、无噪音、无火花、安装维修方便、使用寿命长等特点。所以在国际上已经普遍采用，在一般起重机上，可替代橡胶和弹簧缓冲器，在防爆场所更值得推广。

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.
