You might sneak 2 D9s on if you can ship 100 ton, they are apparently 48,988 kg.

You can probably fit more than two Lunapillars, because the stuff they're moving masses the same, but weighs 1/6 as much, as does the machine itself. It's also always dry - no claggy clays on the moon. You may also want to source counterweight locally if you can. It'll be much less dense, but may an acceptable tradeoff to shipping tonnes of metal ballast by spaceship until you can refine out some low-grade iron from regolith.

Presumably also you make many things out of materials like composites, titanium, aluminium, magnesium and abrasion-resistant materials like ceramics to cut weight and prolong part life in an aggressively abrasive environment where your Cat rep and McMaster Carr are a bit more than a phonecall away. Which will be incredibly expensive, but even using Starship, a tonne landed on the lunar surface ain't exactly cheap and every kilogram counts.
