Article describes a portable, hydraulic-powered tool that can produce 90-, 135- and 180-degree bends in seconds in in-place rebar, after the concrete is poured. One worker reportedly can make up to 800 bends in just one day. Not only does the tool save time and labor, it reduces the risk of injury associated with manual bending and the need for costly splices, couplers and welds.
To operate the device, the user simply slips it over the rebar. A self-contained cylinder activated by a 10,000-psi hydraulic pump then bends the rebar to a preset angle using pulley-like bending wheels. The tool is said to produce bends meeting both American Concrete Institute and Concrete Reinforcing Steel Institute requirements.
