The CALT chassis features a reinforced dual-axle design equipped with heavy-duty off-road tires and an independent torsion bar suspension system. This industrial-grade setups dramatically dampens shocks and prevents frame deformation during transit. The integrated high-reliability braking system and adjustable tow-hitch also allow the compressor to be towed safely by heavy trucks across rugged, unpaved mining tracks and steep gradients.
