WEIGH MODULES Double-Ended Beams
EZ Mount 1
In applications where substantial thermal expansion/contraction
is expected, or room is not available to raise a vessel significantly
for load cell replacement, the EZ Mount 1, also using a double-end,
center-loaded module, is an excellent choice to handle vessel
movement and limited space requirements.
The EZ Mount 1 uses a round load cell that allows the top loading
plate to pivot to correct minor alignment problems. The module
can also accommodate substantial movement in the direction
perpendicular to the longitudinal axis of the load cell.
The load cell in the EZ Mount 1 is supported on hardened circular
spacers. Screws secure it to the base plate. The top chair is held
captive by removable pins on top and bottom of the load cell. This
allows the load cell replacement without raising the vessel, but
merely by taking the load off the module.
EZ Mount 1 modules and load cells are available in alloy steel or
stainless steel in capacities from 5,000 lb to 250,000 lb.

Construction and Features
1) Each end of the load cell is screwed to a base plate through a
hardened cylindrical spacer which is cross drilled to allow the
screw to pass through.
2) The chair assembly has a clearance hole through which the
load cell passes. A hardened load pin is inserted horizontally
at the top of the clearance hole which transmits the load to the
cell. This pin sits in an annular groove at the center of the cell.
3) This arrangement allows the chair to move in practically all
directions, as illustrated in Figure 2-24, while providing
checking in all directions.
4) The load cell can be removed easily by raising the vessel only
enough to relieve the load from the cell.
5) The module is available in capacities from 5,000 lb to 250,000
lb in both mild steel and stainless steel. It may be used with the
alloy steel RL70000 or 5103 and the stainless steel 9103.
