Heavy-Duty Performance

The Compact Heavy is engineered for high-density, heavy-load storage.

Key Benefits

  • Massive Capacity: Supports up to 100,000 kg total machine capacity.

  • Industrial Reliability: Features a 4-point metal rack-and-pinion drive system, providing a durable alternative to belt-driven or plastic-based systems.

  • Dynamic Storage: Built-in storage optimization automatically measures item heights at 25mm intervals.

Engineered for 99.9% Uptime

Unlike competitors using plastic parts or belts that stretch, the Compact Twin uses a 4-wheel metal rack-and-pinion drive. It’s the industrial standard for precision and long-term reliability.
