An ergonomic method for a composite floor structure with metal decking having ribs and flat sections with openings in the flat sections over the center of the I-beams for fastening and flattening the decking on the I-beams, removing contaminates from the I-beams through the openings to form a clean welding zone and welding studs in the clean welding zones. Tools for fastening, removing contaminates and welding are carried by carts having a bottom frame with rollers and an outrigger that keeps a working end of the tool perpendicular to the composite floor structure. In operation as the carts are rolled over the metal decking the rollers contact the ribs while other rollers extend over and free from contacting the flat sections. The carts have a tool balancer to minimize the effort required of a worker to raise and lower the tool into working position from an upright position.
An ergonomic method for fastening and flattening a composite floor structure with metal decking having openings over the center of underlying I-beams with a cart having a rectilinear structure with a top frame, a bottom frame and a front frame, said bottom frame has front and rear transverse members joined to lateral side members, said front transverse member is positioned inside outboard ends of lateral side members, a plurality of spaced apart ball rollers or wheels are positioned on an underside of front and rear transverse members and lateral members, said outboard ends with rollers forming an outrigger, said front frame joined to top frame and bottom frame with vertical side members and with an intermediate vertical member with upper and lower brackets for attachment of a vertical slide positioned between outboard ends of lateral side members, said fastener tool attached to the slide, said method comprising:
In a composite floor structure with metal decking having openings over the center of underly I-beams, an ergonomic method for grinding a top flange of the underlying I-beams through the openings with a cart having a rectilinear structure with a top frame, a bottom frame and a front frame, said bottom frame has front and rear transverse members joined to lateral side members, said front transverse member is positioned inside outboard ends of lateral side members, a plurality of spaced apart ball rollers or wheels are positioned on an underside of front and rear transverse members and lateral members, said outboard ends with rollers forming an outrigger, said front frame joined to top frame and bottom frame with vertical side members and with an intermediate vertical member with upper and lower brackets for attachment of a vertical slide positioned between outboard ends of lateral side members, a grinding tool attached to the slide, said method comprising;
