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 1.2. If installing the mounting frame directly onto the structure of the roof follow the steps in Section 1.3. If assembling the mounting frame at floor level and attaching it to the roof structure, follow the steps in Section 1.4. See Section 12.0 on page 12 for a parts list.
Safety
The dimensioner can be mounted to the building’s I-beam rafter or Z-channel purlins using a frame constructed of extruded structural aluminum (8020). When properly constructed and attached, the frame supports the largest LTL XL dimensioner with a greater than static 5:1 safety ratio. If required by local regulations, the buyer is responsible for organizing an independent third party to evaluate and certify the installation is suitable and safe.
80/20 Mounting Frame Preparation
Use the following steps to ensure that the frame is ready to assemble and install:
- Determine mounting surface and frame configuration (Section 2.0 on page 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 purlin configuration (Section 3.2 on page 5)
- Cap 80/20 ends and form arm assemblies (Section 4.0 on page 7).
Direct Roof Assembly
- Attach spans to structure:
- Primary I-beam rafter configuration (Section 5.1 on page 7)
- Secondary Z-channel roof purlin configuration (Section 5.2 on page 8)
- Install vertical arms (Section 6.0 on page 8).
- Install lower horizontal bars (Section 7.0 on page 9).
- Attach iDimension assembly to mounting frame (Section 8.0 on page 9).
Floor Assembly
- Assemble and square the frame (Section 9.0 on page 10).
- Attach spans to structure:
- Primary I-beam rafter configuration (Section 5.1 on page 7)
- Secondary Z-channel roof purlin configuration (Section 5.2 on page 8)
- Attach frames to roof structure (Section 10.0 on page 11).
- Attach iDimension assembly to mounting frame (Section 8.0 on page 9).
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.
- Insert the T-nut into 80/20 channel at an angle.
- Rotate nut into the 80/20 channel.
- Seat T-nut into channel.
- Fasten screw into T-nut to secure accessory to the bar.
- 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
Configurations
The iDimension 80/20 Mounting Frame is attached either to a primary I-beam rafter or the secondary Z-channel roof purlins.
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.
| Model | Distance |
| iDimension LTL | 142 in (3.607 m) |
| iDimension LTL-XL | 142 in (3.607 m) |
| iDimension Flex | 139 in (3.531 m) |
Table 1. Distance From Mounting Frame to Floor
I-Beam Rafter Configuration Dimensions
The I-beam rafter configuration is supported by 80/20 bars that are attached to the bottom flange of a roof structural I-beam.
Calculate length for each vertical 80/20 (L1) bar from height of structural I-beam.
L1 = H1 – F1 – 5 in (.127 m)
- H1 = Distance from floor to base flange of structural I-beam
- F1 = Distance from bottom of mounting frame to floor. See Table 1 on page 3.
NOTE: Distance from Sensors to floor must be 132 in ± 1 in (3.352 m)
Z-Channel Roof Purlin Configuration Dimensions
The Z-channel roof purlin configuration is compatible with 80/20 bars that span between at least two Z-channel roof purlins.
Z- Channel Purlin Configuration Vertical 80/20 Bar Length
Calculate length for each vertical 80/20 bar (L2) from the height of the top of the 80/20 span at the hanging point. L2 = H2 – F2 – 5 in (.127 m)
- H2 = Distance from floor to the top of the 80/20 span at the hanging point.
- F2 = Distance from bottom of mounting frame to floor. See Table 1 on page 3.
Z- Channel Purlin Configuration 80/20 Span Bar Length
Calculate length of each horizontal 80/20 bar (L3) that spans from Z-channel to Z-channel.
80/20 Arm Assemblies
Form arm assemblies with hangers and end caps before attaching to spans and systems. All 80/20 bars must have an end cap attached. Apply meduim strength thread locking compound and tighten screws to 6 ft-lb (8.1301 Nm).
