SVI Trucks has delivered six heavy rescues to the Calgary Fire Department. They are built on Spartan MetroStar cabs and chassis, powered by Cummins L9 450-hp engine and Allison 3000EVS transmissions. They have Onan generators and Command Light CL Series light towers. The rescues have suspension kneeling which lowers the apparatus 5 inches for easier access to compartments which feature OnScene Solutions components.
