Terramac - Model RT7R - Rotating Crawler Carrier
With its compact size and 360° rotation, the RT7R can get in and out of remote job sites with anyone hardly noticing – even on the most challenging of terrain. The RT7R’s rotation keeps operators in a forward-facing position at all times for enhanced safety while allowing the operator to offload at nearly any angle for added efficiency.
