Methods, systems and apparatuses for providing high electrical resistance for an upper control assembly (including control handles) of an aerial lift are provided through an isolation member that is integral to the upper control assembly and interposed between fluid lines in the control assembly and a set of fluid conduits that extend from the control assembly towards other portions of the aerial lift. The isolation member is a dielectric element that comprises a manifold that is made of material that is substantially electrically non-conductive, and that has a plurality of through-holes or hoses configured to allow hydraulic fluid to flow through the isolation member into and out of the fluid lines and conduits. These methods, systems and apparatuses are preferably used in upper control assemblies of aerial platforms that can carry one or more operators in order to prevent such operators from electrocution when controlling the lift.

The invention is directed to a method for the construction of an industrial plant, in particular a petroleum refinery, by means of scaffolding units, each of which will be assembled from individual scaffolding components, comprising the following steps: Providing a 3D-construction plan in which building structures of the industrial plant are recorded; Drawing of scaffolding units to be used for the construction of the industrial plant in the 3D construction plan of the industrial plant including modifying of the 3D construction plan with respect to at least one building structure of the industrial plant for use of a predetermined scaffolding unit; Building of the industrial plant according to the modified construction plan and by use of the scaffolding units drawn in the 3D construction plan. The method according to the invention, allows for a significant reduction of scaffolding costs incurred during the construction of any industrial plant. The cost saving effects of the method according to the invention can be further increased by modifying the construction plan, wherever possible, for the use of the predetermined scaffolding units which may be of different or equal design.

A support system for supporting a work surface, such as a floating roof during maintenance of the associated tank. More particularly, the present disclosure is directed to providing a system composed on elements which can be transported without constrictive spaces, assembled within work area, and employed to provide support to a structure above and to provide a safe working environment therein. The support system includes four support members, each having a jack, a lower, and a cap, eight connectors which fix the support members in relation to one another and provide rigidity, and may include two connecting shafts to permit simultaneous adjustment of two jacks on a side of the support system.

The inflatable scaffolding is a self-erecting structure that forms a raised working platform similar to a scaffolding. The inflatable scaffolding comprises a plurality of inflatable bladders, a flooring, a guarding, a ladder, and a pump. The plurality of inflatable bladders is a stack of bladders. When pressurized air provided by the pump inflates one or more bladders selected from the plurality of bladders, the span of the distance of the vertical height is increased. The flooring and the guarding are located on the surface of the plurality of inflatable bladders distal from the supporting surface. When each of the one or more selected bladders is fully inflated, flooring and the guarding form a raised working platform that is similar to the structure commonly referred to as scaffolding. To erect the scaffolding to it greatest vertical height, all the inflatable bladders contained within the plurality of inflatable bladders are inflated.

The platform includes a base support that can be clamped to a boat railing and extendable support arms that support a work platform. Methods of manufacturing the platform are also disclosed.
