One person stationed on top of the scaffolding should then insert coupling pins in the upper ends of the posts and receive an end frame lifted by a helper on the ground. Check that the unit is level, and adjust it, if necessary, by turning the appropriate adjusting screws or sliding additional sturdy wood blocks underneath. If you are erecting a tower, the next step is to tighten all the fasteners, then cover the top of the unit with at least one plank or platform section. Then, with a helper, set one end frame in place and attach a pair of braces to it.Īttach the other end frame. Where the posts of end frames will rest, place one or two wide, thick boards like 2-by-10 lumber or a double thickness of three-quarter-inch plywood, on the ground to serve as a base. Also inspect overhead for power lines do not erect scaffolding near these. Remedy hazards such as debris or obstructions, holes and soft earth. When you are ready to assemble the scaffolding, first inspect the area where it is to go. Also inspect the scaffolding components for damage and missing fasteners. When you obtain scaffolding, carefully read the instructions or safety guidelines that accompany it. A rope or cable is used to haul up supplies. These consist of a mast and pulley designed to fit onto a post of one of the end frames. Coupling pins are simply short lengths of solid steel that fit into the ends of the frames to lock them together.įinally, for hauling materials and supplies to the top of scaffolding, hoist attachments are available. If scaffolding units are to be stacked vertically, guard rails and coupling pins are necessary. These can be set at different heights to level scaffolding erected over an uneven surface. These permit moving scaffolding easily without damaging floors, and lock to prevent the wheels from turning.įor outdoor and indoor scaffolding, adjustment screws that fit into the lower ends of the frames are helpful. For indoor scaffolding, casters are important. In addition to the basic scaffold parts, some accessories are necessary or useful. Two or more planks or a pair of platforms side by side are usually used for each unit of scaffolding. These are made of aluminum or plywood attached to support rails that span the frames and hook over them. Safer and less springy underfoot are scaffold platform sections. They should be 2 feet longer than the length of the unit to allow them to extend 12 inches beyond the frame at each end. Planks for scaffolding must be solid lumber 2-by-10 or 2-by-12 stock rated for use as scaffolding. Regardless of the type, two braces are required for assembling individual scaffold units. Like the rungs of walk-through end frames, the tubes of straddle braces do not span the frames, except near the top. When in place, cross braces form the shape of an X and provide strong support for the end frames. The ends of cross braces fit onto bolts or into specially designed brackets at the top and bottom of the end frames. They consist of a pair of straight steel tubes loosely joined by a single rivet in the center. The ordinary type are called cross braces. These have narrow rungs near one or both posts, but none that spans them except near the top of the frame.īraces are available in lengths that produce scaffold units either 5 or 7 feet long. For ease in walking beneath scaffolding and to enable scaffolding to be erected despite obstructions like shrubbery, special walk-through frames are available.
