摘要： A worker platform assembly is modular in construction so as to be configurable according to the configuration and size, particularly width, requirements of each bridge and to metal surfaces thereof which are to be reconditioned by abrasive stripping and recoating. The assembled platform is suspendable at each end by suspension frame assemblies which are rollable along the parapets of the bridge for repositioning the platform assembly, with the suspension assembly being adjustable to various configurations of parapets. An adjustable curtain frame enables sealed enclosure of bridge surfaces to be treated and optimum access of workers to those surfaces during the treatment. Airborne residue is evacuated by vacuum for subsequent disposal in a manner which does not contaminate the environment, while heavier residue and spent abrasive grit is collected and positively moved off of the platform assembly for subsequent, environmentally safe separation and reconstitution of the grit for reuse.
摘要翻译：工作平台组件在结构上是模块化的，以便可以根据每个桥梁及其金属表面的构造和尺寸，特别是宽度要求进行配置，这些要求将通过磨料剥离和重新涂覆进行再修复。组装的平台在每个端部由悬挂框架组件悬挂，所述悬架框架组件可沿着桥的栏杆滚动以重新定位平台组件，悬架组件可调节到各种构造的护栏。一个可调节的窗帘框架可以使处理过程中桥面的密封外壳得到处理，并使工作人员能够最佳地接近这些表面。空气中的残留物通过真空抽真空以便以不污染环境的方式进行后处理，同时收集较重的残留物和废磨料砂粒并将其从平台组件中积极地移出，以便后续的环境安全分离和重新使用砂粒进行再利用。

Airborne residue is evacuated by vacuum for subsequent disposal in a manner which does not contaminate the environment, while heavier residue and spent abrasive grit is collected and positively moved off of the platform assembly for subsequent, environmentally safe separation and reconstitution of the grit for reuse. The work platform assembly includes a floatation system which permits the work platform assembly to float in a body of water. The floatation system facilitates the maneuvering of the work platform assembly to better access surfaces to be treated. Additionally, the floatation system of the work platform assembly facilitates the transportation of the work platform assembly to a structure located above a body of water.

摘要： A work platform assembly and trailer system for transporting and vertically positioning the work platform assembly adjacent bridge deck surfaces to be treated. The trailer includes front and rear lifting assemblies for supporting, and being removably attached to, an end of the work platform assembly. The lifting assemblies include vertically oriented lifting cylinders for vertically positioning the work platform assembly immediately adjacent the bridge deck surfaces to be treated. The trailer includes wheels and a hitch to facilitate the transport of the work platform assembly to the site of the bridge deck. The work platform assembly is modular in construction so as to be configurable according to the configuration and size, particularly width, requirements of each bridge and to metal surfaces thereof which are to be reconditioned by abrasive stripping and recoating. An adjustable curtain frame and/or other devices enable sealed enclosure of bridge surfaces to be treated and optimum access of workers to those surfaces during the treatment. Airborne residue is evacuated by vacuum into a dust collection system for subsequent disposal in a manner which does not contaminate the environment, while heavier residue and spent abrasive grit is collected and positively moved off of the platform assembly into a residue separation system for subsequent, environmentally safe separation and reconstitution of the grit for reuse. The dust collection and residue separation systems may be removably attached to the trailer.
摘要翻译：一个工作平台组装和拖车系统，用于运输和垂直定位工作平台组件邻近待处理的桥面板表面。拖车包括用于支撑和可拆卸地附接到工作平台组件的端部的前和后提升组件。提升组件包括垂直定向的提升缸，用于垂直地将工作平台组件定位在紧邻待处理的桥面板表面。拖车包括车轮和搭便车，以便将工作平台组件运送到桥面的位置。工作平台组件在结构上是模块化的，以便可以根据每个桥梁及其金属表面的构造和尺寸，特别是宽度要求进行配置，这些要求将通过磨料剥离和重新涂覆进行修复。可调节的窗帘框架和/或其他设备使得能够处理桥接表面的密封外壳并且在处理期间工人对这些表面的最佳访问。将空气中的残留物通过真空抽入灰尘收集系统中，以便以不污染环境的方式进行后处理，同时收集较重的残留物和废弃的磨料砂粒并将其从平台组件中积极地移出到残留物分离系统中以用于随后的环境安全分离和重组砂粒进行再利用。集尘和残渣分离系统可以可拆卸地连接到拖车。
