PT Smart Belt Trainer for Conveyors
Flexco introduces the PT Smart Belt Trainer, developed to further enhance its line of belt tracking products. The PT Smart will join the Belt Positioner and the innovative heavy-duty PT Max Belt Trainer as an option for "medium-duty" tensioned belts. The PT Smart works with both mechanical and vulcanized belts, is made of durable materials, and is easy to install.
The PT Smart Belt Trainer adopts the same characteristics as the PT Max, including the patented Flexco "pivot and tilt" design. With pivot and tilt technology, the PT Smart applies greater belt tracking discipline than conventional pivot-only belt-steering devices, correcting even the most stubborn tracking problems on medium-tension belts. A fully enclosed, stainless steel pivot bearing is found downstream from the roller, creating an almost immediate tracking result. The bearing requires no lubrication and is guaranteed not to seize.
When responding to belt mistracking, the PT Smart turns its idler training carriage away from the direction of drift, simultaneously lowering the end of the carriage opposite the drift while raising the end facing the drift. The resulting tilt increases belt tension along the drift-out side, causing the belt to center itself naturally while keeping the load distributed across the training carriage and avoiding the need for concentrated steering forces along the belt edge.
The pivot and tilt action is initiated by two sensor rollers installed alongside both belt edges. Extra-long sensor arms avoid any potential for belt binding or pinching as corrective training takes place and allow greater sensitivity to minor amounts of belt drift. The degree of drift sensitivity is user-adjustable from beside the conveyor, using the PTS Sensor Adjustment Arm.
The PT Smart is designed for use with medium-duty belts up to 1600 PIW with maximum tension and thickness of 1 in (25 mm). Models are available for return-side installation for belt widths from 18 to 72 in (450 to 1,800 mm). Both standard and underground versions are available for a variety of different applications.
