    • Apparatus for safely and efficiently removing a layer of asbestos or like material from a generally planar or corrugated ceiling surface, I-beams or the like is disclosed and comprises a head assembly including an outer cover having a first open portion adapted to face the asbestos layer and a second open portion communicating with suction means through asbestos collecting means, an open ended inner wall member mounted within the outer cover to define an air passage between the inner wall member and the outer cover, and a rotary wire brush mounted within the inner wall member and adapted to engage and remove the asbestos layer from the surfaces to be stripped. The apparatus also includes adjusting means for moving the head assembly to an operative position wherein the rotary wire brush is in scraping contact with the asbestos layer with a small gap present between the peripheral edge of the first open portion of the outer cover and the surface to be stripped. During a scraping operation, the suction means sucks the ambient air into the air passage in the outer cover through the small gap so that the sucked air entrains asbestos laden dust from the inner wall member to thereby prevent the escape of the removed asbestos to the ambient environment.
    • 公开了一种用于从大致平面或波纹状天花板表面,I型梁等安全且有效地去除石棉或类似材料层的装置,其包括头部组件,其包括具有适于面对石棉层的第一开口部分的外部盖 以及通过石棉收集装置与抽吸装置连通的第二开口部分,安装在外盖内的开口内壁构件,以在内壁构件和外盖之间限定空气通道,以及安装在内壁内壁内的旋转钢丝刷 并且适于从待剥离的表面上接合和去除石棉层。 该装置还包括用于将头部组件移动到操作位置的调节装置,其中旋转丝刷与石棉层刮擦接触,在外盖的第一开口部分的周边边缘与表面之间存在小的间隙 剥离。 在刮擦操作期间,抽吸装置通过小间隙将环境空气吸入外盖中的空气通道,使得吸入的空气从内壁构件携带石棉载满灰尘,从而防止被去除的石棉逸出到环境中 环境。
