The driving of the tread rollers on the HYTROL minimum pressure conveyor is accomplished with the top surface of a standard section endless V belt. The strength and wear qualities of the tread rollers and this belt have been thoroughly tested for continuous duty. To maintain the driving of the tread roller, the pressure roller is mounted in spring adjusted carriers (See Photo) which sense the required driving friction regardless of the length of accumulated load. This pressure can be maintained constantly to give a 2%minimum back pressure in either a forward or reverse direction. In the event of extreme changes in unit load (weight of box or package), convenient knurled thumb adjusting nuts can be turned to accept this heavier load. This method eliminates the need for selecting proper tension spring holes in trigger mechanisms or jogging cleats on driving belt and eccentric (off center) tread rollers. By maintaining a constant minimum pressure on the tread rollers, long loads may be conveyed, accumulated or stopped on the conveyor at any point using very little motor horsepower and giving practically no pressure between boxes or packages. • HOW IT WORKS Minimum Back Pressure (2% of Total Distributed Load) Tread Roller Knurled Thumb Adjusting Nut Spring Adjusted Carrier Conveyor shown with optional floor supports LOAD CAPACITY CHART @ 65 FPM HP OVERALL FRAMEWIDTHS–12" TO 24" TOTAL LOAD (Lbs.)
