RT9 | Alta Equipment Company

Our first crawler carrier remains the best in its class. Contractors in the drilling, pipeline, utilities, and general construction industries have come to rely on the RT9 for its versatility and reliability.

 

Compact enough to not require a load permit when transporting, but still featuring an 18,000 lb. carrying capacity, the RT9 is ready to work on job site after job site.

  • Move up to 9 tons of materials and equipment into difficult environments efficiently and effectively.
  • The RT9’s customizable chassis is ideal for mounting specialty equipment like cranes, drills, water tanks, spray booms, hydroseeders, fifth wheels, and more.
  • Rollover protective structures (ROPS) and falling object protective structure (FOPS) ensure the safety of your operators.
