Some projects have small, tight spaces that require compact equipment with the maneuverability of a sports car, not an 18-wheeler. In these cases, contractors employ small dozers, mini-excavators, and compact track loaders. Add to that mix a small milling machine specifically suited for removing road pavements, milling pavement strips or milling tie-ins.
The latest addition from Roadtec Inc. to its line of milling machines is the RX-100e -- a highly maneuverable mini-size mill with a base cutting width of 20 inches, maximum cutting depth of 8 inches deep, and a drum diameter with teeth of 30 inches.
The weight, power, and dimensions of this compact machine make it the perfect option for cutting trenches, demarcation and cutting around manhole covers, or for other narrow spaces. The RX-100e features a shipping weight of 15,840 pounds, a length of 12 feet 8 inches, and a width 4 feet 8 inches.
The RX-100e is a 140-hp machine with a hydraulically driven drum and features large access doors on both sides of the machine for maintenance access to the interior components.
A Cummins QSB 4.5 Tier 4i compliant diesel engine powers the small utility cold planer. The engine is cooled by a high-efficiency variable speed fan. The speed of the fan is based on cooling demand, which is designed to decrease the engine load and increase the fuel economy of the machine.
To add functional versatility, the right, rear leg tube on the RX-100e is positioned alongside the cutter housing for normal milling, but the leg tube can also be rotated to a position in front of the cutter housing for flush cut operations.
The operator station includes simple controls and the operator seat, which incorporates comfort suspension, can slide out to the right of the machine for enhanced visibility.
The Roadtec RX-100e utility milling machine is designed for congested urban areas and other confined work sites.
