1. Introduction
In this Translink™ manual, you will find a step-by-step approach to installing the
load cell mount in an easy, logical manner. You'll find complete information from
assembling and installing the components to testing the scale for weighing accuracy. Troubleshooting and replacement parts sections are also included in this
manual.
The Translink load cell mount is used for heavy capacity tank and truck weighing
applications. The mount is made of fabricated and hardened tool steel in capacities
of 25,000 lb to 100,000 lb. The pendulous action of the links allows self-centering
of the weighing platform, and the platform has free movement in all directions in
the horizontal plane. Install platform bumpers to prevent overtravel.
The mount is compatible with four different tool steel, double-ended shear beam
load cells. The RL75040A and the Sensortronics 65040A load cells are environmentally protected styles, whereas the RL75223, RTI 5223, and Sensortronics
65040S load cells are hermetically sealed styles.
The installation should be planned by a qualified structural engineer. Each installation is unique, and this manual is meant to serve only as a general guideline for
installation.

2.1 General Installation Guidelines for Translink
1. Unless a good ground is already provided, install a system ground in the pit in
close proximity to the junction box. Use at least 1/2" x 8' copper-clad ground
rod. The indicator, junction box, weighbridge, and lightening protection
devices will be hooked to the system ground. Hook all other devices, such as
the printer, to the same AC power supply and ground as the indicator.
2. If the pit fills with water, proper drainage must be provided so that the load cell
mounts are not standing in water. Also, drainage loops should be provided on
any conduit or cables going to the junction box or load cells.
3. Install bumper bolts between the scale platform and the walls of the pit. Leave
about 1/8" clearance or as applicable for
temperature changes.
4. The mount must be positioned in the
direction of travel (Fig. 2-1).
5. The mounting surface for the base plate
and girder chair must be level and parallel
so that side loads and bending moments
are minimized. The mount assemblies
must be plumb and level within ±0.5°.
6. Because the load cell could be damaged during installation, do not use
excessive force or slam parts on the load cell.

When any welding is required on the platform, remove the load cell from
the mount so it is not damaged by welding currents or excessive heat.
