How it works · Installation method

Installation with a tracked mast machine

A tracked machine with a vertical mast: the mast holds the T-Block straight while the rotary drive screws it in, and the pilot-hole tool fits on the same mast. It is the machine for solar farms, industrial installations and beaches.

When to use it

It is used when there are many T-Block ground screws that must all sit in line and at the same height: the mast holds them vertical one after another. The tracks take the machine over sand and muddy fields as well.

  • Ground-mounted solar farms
  • Beach clubs: decks, cabins, structures on sand
  • Industrial and agricultural installations
  • Parks and green areas with many points

What you need

The pilot-hole tool is part of the machine and is not in the catalogue. Between the rotary drive and the T-Block you use the same adapter as on the excavator.

The adapter

For mast machines with a threaded cone and a 50 mm male output: 50 mm socket, PMBB coupler and the socket for the T-Block head.

For headless T-Block models for a Ø60 post

The temporary hexagon interface slides into the top of the T-Block and takes the 60 mm socket. It comes off when installation is finished.

Step by step

  1. Green tracked machine with its mast folded coming down the ramps from the lorry, on the seafront at Misano Adriatico in front of the beach cabins.

    Step 1: Bring the machine and the T-Block screws to site

    The tracked machine arrives on a lorry and comes down the ramps; the T-Block screws are laid out along the rows.

  2. Laser level on a tripod in the middle of the installation area on sand, with a row of flanged heads already at level.

    Step 2: Set out the field

    The surveyor, or a GPS, pegs out every point; the laser level gives the height of the heads.

  3. Green tracked mast machine opening a pilot hole in a field: the drill rod goes into the ground beside the mast, with the operator at the controls, seen from behind.

    Step 3: Pilot hole on the same mast

    In hard or stony ground, the pre-drilling tool is fitted to the mast and the pilot hole is opened at the pegged point. Pre-drilling and screwing in happen on the same machine: once the hole is done, you switch to the rotary drive.

  4. Foot of the mast and rotary drive above a T-Block ground screw going into the sand, with installed heads in the background.

    Step 4: Screw in on the same machine

    Switch to the rotary drive, attach the T-Block, and the mast keeps it straight while it turns and goes into the ground.

  5. Flanged heads of T-Block ground screws at level in the sand, in regular rows.

    Step 5: Check, row by row

    Plumb and level are checked on every T-Block: a spirit level on the flange shows whether the head is level.

  6. Field of T-Block ground screws installed on the beach at Misano Adriatico in front of the seafront hotels, ready for the structure.

    Step 6: Fix the structures

    Panel frames, decks and roofs are fixed on the heads. There is no concrete to wait for.

Different machines, the same installation

The installation can be done with different tracked machines: what you need is the mast, the pre-drilling hammer and the rotary drive. In the photos, the green machine on the beach and the orange one in the Monterchi park and on solar farms: the ground changes, the sequence stays the same.
