TCM 180/TCM 180i: Self-propelled curing unit with new features
The Wirtgen pavers will be complemented by the self-propelled, track-mounted TCM 180/TCM 180i texture curing unit on display. The curing unit’s modular design permits working widths between 13 ft., 1 in. and 59 ft., 1 in. (4m and 18m). The TCM 180/TCM 180i can create different surface textures using one single system to meet all requirements, in addition to the well-established functions of transverse brushing and spraying, and longitudinal brushing and spraying; even a diagonal finish is possible. Meander spraying is a special option: this method permits transverse spraying during uninterrupted travel.
Hot-water system for easy cleaning
Cleaning the spray systems of curing machines economically is something of a challenge. With this in mind, Wirtgen has integrated a hot-water system with a 24-gal. (90-liter) tank in the TCM 180/TCM 180i. With this system, curing agent adhering to the inside of the pipes can be completely removed with water up to 140°F (60°C) in temperature -- and the entire spray system quickly and reliably cleaned -- all at the push of a button and by shifting two ball cocks.
Brush-cleaning unit ensures quality of the surface texture
Another new feature is the lateral brush-cleaning unit. It removes slurry build-ups which adhere to the brush during changes of direction when applying a transverse brush finish. Before the brush is lowered back down to the concrete surfacing, it is set to the optimum angle of incline via the adjustable system to meet customer requirements. This prevents deep impressions which might damage the edge of the concrete pavement.
