Pile cap and bearing bolts, slew drive bolting, torque tube splice bolts, damper pins, module rail U-bolts, module clamp bolts and bonding hardware, made in Houston to your drawings and specifications.
Two bays of a single-axis tracker row: a 5 in. square torque tube on driven W6 posts 25 ft apart, turned by a slew drive on the centre post and carrying twelve 2278 × 1134 mm modules. That is two of the twelve bays of a typical 78-module row; the rest of the row and the next rows are drawn faintly. It comes apart in the reverse of how a crew builds it: the module bolts and modules, the U-bolts and rails, the dampers and bonding jumpers, the tube splices, the bearing caps and drive flanges, then the tube sections, the slew drive, and the bearing housings and pile caps off the posts. The bolting we make is in colour. Press Solid view for a galvanized-steel model.
Four galvanized heavy hex structural bolts (ASTM F3125 Grade A325) through the cap bracket and both flanges of each driven W6×9 post, in slots so the cap can be set to height.
Four hold each bearing housing down on its pile cap through crossed slots, so it lines up with the rest of the row; two more close the housing cap over the polymer bearing.
The drive bracket to the flanges of the W6×15 drive post, and the slew drive down onto the bracket: four each.
Cap screws holding the gear motor on the slew drive's worm housing.
Join the torque tube adapters on both sides to the slew drive's turning rings, eight a side.
Eight through-bolts across each splice sleeve where sections of the 5 in. square tube join, and four through each drive adapter.
The two bolt-pins each wind damper hangs on, its lower bracket bolts through the post flange and the U-bolt holding its upper arm on the tube.
One square U-bolt round the tube at every module rail, with a serrated flange nut on each leg inside the rail.
Four per module through the frame's mounting slots (9 × 14 mm at 1400 mm pitch) into the rails; roughly 7,000 per megawatt.
Each end of the braided jumper that bonds the turning tube to every bearing post across the polymer bearing.

The post and torque tube sections, the structural bolt dimensions and the module size and slot pitch follow the published standards and data sheets; the bearing housing, pile cap, splice sleeve, slew drive, damper and rail shapes are illustrative, and the bolt sizes, the post spacing and the counts are typical for a 78-module row on 13 posts. Your drawings govern. We manufacture to your drawings and specifications.
Drawn to the AISC shape tables (W6×9 and W6×15 posts, HSS 5 × 5 × 3/16 torque tube), ASTM F3125 Grade A325 structural bolts with ASME B18.2.6 heavy hex dimensions, ASTM F2329 hot-dip galvanizing, and a 2278 × 1134 × 35 mm module with 9 × 14 mm frame slots at 1400 mm pitch.
