RT9U | Alta Equipment Company

MIDSIZE CARRIER FOR MASSIVE JOBS

Compact enough non-permitted load when transporting, but still featuring an 18,000 lb. carrying capacity, the RT9U is ready to streamline utility transmission and distribution.

 

Extended front and rear frame extensions and multiple hydraulic configurations allow you to customize the RT9U nearly any way you need.

  • Advantageous Size: Largest carrier in its class allowing it to accommodate over-sized support equipment.
  • Ease of Transport: Haul the unit from jobsite to jobsite on a tag trailer without special permits.
  • Cummins Engine: Carrier delivers maximum power and torque for traversing rugged terrain with ease while at maximum capacity.
