Route the rear sensor wiring through the large open-
ing in the channel. An additional shield is supplied
for the two Rear Shear Beam Load Cells (to cover
the sensor’s cable exit). Mount the cable clamps
inside the channel (3 small clamps per side) to prop-
erly retain the wiring within the channel.
During this step, pull all four Shear Beam Load Cell
wires through the channels toward the LSS Module
mounting location. Excess wire length should not be
allowed to hang below the platform (it will be bun-
dled near the LSS Module).
5. Mount the Platform to the Shear Beam Load Cells.
Carefully maneuver the platform support structure
toward the platform (from Ground Control). Make
final adjustments by sliding the platform on the saw-
horses or barrels. Ensure that sensor wiring is not
damaged during this step. Study the Installation
Drawing’s detail regarding how components are
placed. From below, insert the 5/8 inch Shank bolts
(15/16” Head) with washers that mount the Platform
to the Shear Beam Load Cells. Place the spacer
bushing on top of the Shear Beam Load Cells
(between the platform and sensor), with the beveled
feature toward the sensor. Secure the Hex Lock Nut
on top of the platform but do not completely tighten.
6. Torque all Fasteners to Specification. First, ensure
that the platform is resting completely on the plat-
form support structure (adjust using the Ground
Control). Torque the two 1/2 inch Shank (3/4 inch
Head) bolts between the platform support structure
and the Shear Beam Load Cell to 75ft-lbs (105 Nm)
(do all four sensors), ensuring that the access holes
in the Load Cell Guard Brackets for the 5/8 inch
Shank bolts remain aligned. Next, torque the 5/8
inch Shank (15/16 inch Head) between the platform
and Shear Beam Load Cell to 50 ft-lbs (68 Nm) (do
all four sensors).
7. Mount the LSS Module to the Platform. Secure the
LSS Module to the bracket with the hardware
described in the Installation Drawing. Next, mount
the assembly to the platform mid-rail (drill mid-rail if
necessary).
