GOMACO’s T/C-400 and T/C-600 texture/cure machines are now available with a skewed tining option. It allows the travel of the tining bars to run a skewed path, while the frame of the machine is square to the slab. It simplifies the ability to transverse tine on newly paved streets and highways requiring a skew texture. In the past, the frame of the texture/cure machine had to be skewed and incorporated the use of a secondary crawler track mount with a center pivot, which added length to the machine. The skewed frame then had to be readjusted for transport.
Simplicity was the main design concern. The sprockets, chains and mechanical items are off-the-shelf pieces that are easily replaceable. The tine rake on the texture/cure is gear driven, and as the rake travels across the slab, it moves longitudinally in a sliding mechanism through the mount. The final tining pattern is accomplished simply by sliding only the rake. No matter where the broom starts or stops, it always has the same skewed pattern, because it is timed off the carriage’s back and forth travel.
The sliding movement is controlled by a timing chain that runs from end panel to end panel. The direction of the skew can easily be changed by moving the timing chain either over or under the main drive sprocket on the upper carriage.
The skewed tining option can also be easily retrofitted to existing GOMACO texture/cure machines. The new option adds to the versatility of the machines by offering skewed as well as longitudinal and transverse tining on mainline paving projects.
