Floor Mounting

Floor Mounting

All of our BATMs are equipped with mounting holes in their base. Anchoring is highly recommended for various reasons. Lighter BATMs can be lifted and carried away with cash inside of the unit, and taller BATMs (e.g. BATMFour) have the potential to be tipped over. This creates the risk of serious injury, or even death! As an owner, you are responsible for operating your machines in the safest way possible, and determined attackers can pry poorly mounted BATMs in a matter of minutes. Fasten your BATMs securely whenever possible. This article is intended to help you get started.

Floor Material

Most of the time you will be working with concrete (vs. wood), thus this manual is mainly focused on that environment. Evaluate the flooring and the usable thickness. Go deep, but not too deep.

  • Are there any utilities running under your desired location? The last thing you want is your drill bursting a water pipe or electrical conduit!

  • Many retail concrete slabs are 100 mm (4") thick, so attempting to secure a BATM using 150mm (6”) rods is ill-advised and probably a waste of materials.

  • Concrete slabs typically have a plastic liner underneath, and piercing that liner can allow moisture to well up into your BATM, and that moisture can damage your BATM.

Techniques

For concrete floors you have basically two options:

  • Bolts and anchors

  • Threaded rod (recommended)

Threaded rod is recommended (when compared to anchors) because the rods can be sunk deeper into the base flooring. Epoxy is recommended in every application, as both the threaded rods and anchors should be sealed to the concrete underlayment. Use washers to distribute the load.

Sizing:

The holes in the BATM base for bolts are typically 18mm in diameter (M16, or 1/2”). The bit size of the holes you drill depends on manufacturer recommendations:

  • anchors: see the box or check the manufacturer website.

  • epoxy: add ~2mm to the specified diameter.

Depth is totally at your discretion. The deeper, the better - but at some point the depth becomes irrelevant as the metal’s sheer strength doesn’t increase with length.

Installation:

  1. Place your BATM in the desired location.

  2. Check that you can easily and fully open all the doors and panels.

  3. Mark the positions of the holes on the tiles through the bottom of the BATM.

    1. Slight variations may be encountered between production runs, and drilling a hole in concrete is unforgiving. It’s better to measure twice & drill once; don’t rely on templates unless you’ve checked them. Samples are provided below for reference only.

  4. Move the BATM from the mount location to get clearer access for drilling the holes.

  5. Drill out the marked holes to the desired depth (100mm/4+ inches for most commercial floors).

    1. If using threaded rod, cut the rods to the desired length and attach a washer & nut to one end.

    2. See a cross section of a mounting point in the picture below.

  6. Return the BATM to its final mounting position.

  7. Deposit some pre-mixed epoxy into the holes, and (quickly, within a few minutes)

  8. insert the anchors or threaded rods fully into the epoxied holes.

  9. Attach any washers and nuts (or bolts), loosely securing the BATM to the floor.

    1. If using threaded rod, return after 24 hours (curing time) to tighten the nuts.

    2. If using anchors, tighten them to be snug (only).

    3. Do not overtighten either type!

WARNING: BE CAREFUL TO AVOID OVER-TIGHTENING!

Over-tightening the mounting bolts may warp the base plate & misalign the vault door. Once the door is jammed, there’s no magic way to open it, or remove the mounting bolts. A snug fit will work just as well as a tighter fit, but without the penalty of malfunction.

Easy does it!
