Air-powered Saw: Cuts Panels and Pipe Air-powered Saw: Cuts Panels and Pipe

The Esco APS-438 Air-Powered Panel Saw can be used to make cuts in stainless-steel, super-duplex stainless-steel, inconel, concrete-lined pipe and other hard construction materials. The saw comes with a standard fiberglass-reinforced blade or an optional carbide-tipped steel blade and makes a 43⁄8-in.-deep cut. The APS-438 easily can attach to boiler panels using a pair of weld tabs or a quick clamp for trimming new panels. A rigid chain-mounted clamp system allows for single-pipe work. The saw is powered by a 3-hp motor and requires only 80 cfm per minute.

Pair of Cranes on the Job: High Hook Heights Pair of Cranes on the Job: High Hook Heights

WolffKran’s Model 6031.8 slewing tower crane allows for rapid construction at heights over 120 meters, with a minimal foundation footprint. The crane has a jib length of 50 m and a maximum load of 8.5 tons. A pair of these cranes recently were employed at a large-scale power station in Mannheim, Germany. The two cranes employed were capable of freestanding hook heights of 82.5 m and 98 m, respectively, and could reach hook heights of over 120 m with only a single tie. Due to space constraints on the ground, the cranes were ballasted with 120-ton and 140-ton central ballasts, respectively. The weights then could be easily removed once the work was completed, allowing for more laydown space on the jobsite. For the power-station project, the cranes were used in the slipform construction of a pair of stair towers, and their simple tie system allowed for the use of a single slipform stop on each crane, saving considerable time.
