1.2 Scale Components
The RoughDeck FXB has six major components as shown in Figure 1-1 on page 2. Those components and their
descriptions are listed in the following table.
Table 1-1. RoughDeck FXB Scale Components
FXB Scale Component Description
Weigh Platform (deck frame
and deck plate) A rigid welded frame unit with a removable deck plate upon which weight is placed. The
applied load is transmitted from the weigh platform, to the load bridge, to the levers, and then
to the load cell.
Lever System Structural members on each side of the scale are supported from the base by the fulcrum
flexure. The structural members also support the weigh platform through the lever system to
the tip of the primary lever: the primary lever is supported by the load cell.
Load Cell Electronic force measuring device mounted in a corner of the scale and rigidly fixed to the load
bridge structure. Wire rope runs from one end of the load cell to the tip of the primary lever.
Flexure Plates Flat, high-strength thin plates that transmit the load forces due to the weigh applied to the
platform and to the lever system. The flexures provide maintenance free pivot point that
supports the levers from the base and transmits forces from the load bridge to the levers and
on to the load cell.
Load Bridge Two pieces of tubing or channel iron, one on either side of the scale and tied together by two
cross members. The weigh platform is supported by the load bridge through four platform
support pipes. The load bridge is suspended from the lever system through the load flexures.
Base Frame A rigid one piece, welded unit that supports the remaining scale system. The fulcrum flexure
support stands are welded directly to the base frame.
