APPARECCHIATURA MOBILE A PASSI LUNGO UNA PARETE,PARTICOLARMENTE PER GENERATORI DI VAPORE NUCLEARI

摘要

An improved surface traversing apparatus has an anchor finger selectively movable laterally of another anchor finger into near or substantial alignment with an opening in a member for insertion thereinto and includes one or more of the fingers being mounted to a base portion of the platform by a mounting arrangement which allows one finger to be deflected laterally relative to another finger such that the finger being inserted may deflect into exact alignment with the receiving opening by lateral engagement with the sidewall of the opening. Each finger is resiliently mounted to a connecting member which is, in turn, connected to the base portion of the platform. The resilient mount for each finger normally centers the finger and allows both pivotal and translatory displacement of the finger relative to the connecting member. A cylindrical adaptor is fixed to the finger and is radially supported in a circular opening in the connecting member by a resilient O-ring therebetween in mutually opposing radial engagement therewith.
