Installing Pit Frames
The pit frame accessory is a one-piece welded unit.
─ There are three (3) different type frames with six (6) sizes for each type.
─ Two (2) are for the standard duty scale and one (1) is for the heavy capacity.
─ The Pit Frame is designed for in-floor, or 'flush', applications.
─ Standard duty frames are available in mild steel for all six floor scale sizes
For normal installations, a hole is cut in the concrete, the pit-frame accessory is
installed in the hole, then concrete is poured around and under the frame. The
concrete work and frame setting is usually done by a contractor, with a scale
technician completing the project by setting and installing the scale. Once cured, the
scale platform is set into the frame and installation can be completed. No additional
welding required.
STEPS
1. Place the pit frame in the approximate position it will occupy on
the floor.
2. Mark out the position of the hole to be made.
─ The hole must be a minimum of twelve inches (12") wider on all
sides than the pit frame.
─ The hole will have to be deep enough to accommodate the pit coping, plus the
thickness of the pit floor.
─ Use the drawing in Appendix IV for measurements.
─ Should pit drainage be required, slope the pit floor to an installed drain while
maintaining a level area at each corner.
3. Cut the hole in the concrete floor.
4. Clean up any debris in the way of further installation steps.
5. Set the frame in the hole supported at about the correct height.
6. Set two 2x4 's on edge (longer than the width of the hole) across the opening.
