Slew Drive Seats for Solar Trackers

The seat that carries a tracker’s slew drive on top of its post: laser-cut cheek and top plates with stiffening fins, welded square, galvanised and bolted to the post.

Where the tracker turns

The slew drive turns the whole row. Its seat has to sit level and square on the post, or the drive wears and the row twists.

Cheek and top plates

Cut on the fibre laser and welded in a fixture by robots, so the top plate comes out flat and square every time.

How is it possible at Allmarc?

Stiffening fins

A row of fins under the top plate carries the drive’s load down into the cheeks.

04 / 06

Bolted to the post

Through-bolts clamp the cheeks to the post; the drive bolts on top.

Made in batches

Seats come off the line in batches, galvanised and counted for the site.
