80/20 Mounting Frame Installation
The iDimension 80/20 Mounting Frame System is designed to be suspended from a steel roof structure. iDimension LTL, iDimension LTL-XL and iDimension Flex systems can be attached to the iDimension 80/20 Mounting Frame. Consult with Rice Lake Weighing Systems for more information.
1.0 Introduction
The iDimension 80/20 mounting frame can be installed directly onto the roof structure in pieces or it can be assembled on the ground and attached to the roof structure. Start all installations by completing steps in Section 1.1. If installing the mounting frame directly onto the structure of the roof follow the steps in Section 1.2. If assembling the mounting frame at floor level and attaching it to the roof structure, follow the steps in Section 1.3. See Section 12.0 on page 12 for a parts list.
1.1 80/20 Mounting Frame Preparation Use the following steps to ensure that the frame is ready to assemble and install:
1. Determine mounting surface and frame configuration (Section 2.0 on page 2). 2. Calculate dimensions and cut 80/20 bars needed for the frame:
· Primary I-beam rafter configuration (Section 3.1 on page 4) · Secondary Z-channel roof perlin configuration (Section 3.2 on page 5) 3. Cap 80/20 ends and form arm assemblies (Section 4.0 on page 7).
1.2 Direct Roof Assembly 1. Attach spans to structure: · Primary I-beam rafter configuration (Section 5.1 on page 7) · Secondary Z-channel roof perlin configuration (Section 5.2 on page 8) 2. Install vertical arms (Section 6.0 on page 8). 3. Install lower horizontal bars (Section 7.0 on page 9). 4. Attach iDimension assembly to mounting frame (Section 8.0 on page 9).
1.3 Floor Assembly 1. Assemble and square the frame (Section 9.0 on page 10). 2. Attach spans to structure: · Primary I-beam rafter configuration (Section 5.1 on page 7) · Secondary Z-channel roof perlin configuration (Section 5.2 on page 8) 3. Attach frames to roof structure (Section 10.0 on page 11). 4. Attach iDimension assembly to mounting frame (Section 8.0 on page 9).

iDimension 80/20 Mounting Frame Installation

1.4 Roll-in T-nut Roll-in T-nuts are used to screw accessories into the bar. They can be inserted by sliding them in from the end of the 80/20 bar or they can be inserted into the channel of the 80/20 bar.
1. Insert the T-nut into 80/20 channel at an angle.
2. Rotate nut into the 80/20 channel.
3. Seat T-nut into channel.
4. Fasten screw into T-nut to secure accessory to the bar.
5. Apply medium strength thread locking compound and tighten screws to 6 ft- lb (8.1301 Nm).

NOTE: Over-tightening the screw may cause the screw to strip out of the T-nut. If screw spins freely, replace the T-nut

3.0 Calculate Frame Dimensions
The dimensions of the frame’s horizontal 80/20 span bars depend on the structure they are secured to. The dimensions of the frame’s hanging vertical 80/20 bars depend on the height of the structure. The distance from the frame’s lower horizontal 80/20 bars to the floor depends on the iDimension model. (Table 1) The final height of the iDimension sensors must be 132 in ± 1 in (3.352 m) from the floor. The following sections show how to calculate dimensions.
