Binders, also called tighteners, are used to bind goods and tighten objects. They are often used in trucks to bind goods. The materials are polypropylene and polyester, usually 1T, 3T, 5T, 7.5T, and 10T. In recent years, the transportation industry has developed faster and faster, driving the surrounding industries to gradually develop. Therefore, tie down straps manufacturer is also committed to making certain improvements and upgrades to product quality. From manual to automatic, and today we are talking about the hydraulic automatic tensioning device.

The hydraulic automatic tensioning device is an automatic tensioning hydraulic system in a retractable belt conveyor. The tensioning device has a belt storage function. The storage belt is tightened manually. When the belt conveyor is running, The tension of the conveyor belt is automatically adjusted through the hydraulic system. When the tension of the rubber belt is greater than the specified value, the control valve moves down.

Due to the pressure difference generated by the one-way valve, the hydraulic control valve also moves downward, causing the hydraulic motor to run idling to loosen the rubber belt. When the wear-resistant conveyor belt tension reaches the specified value, the control valve is in the middle position and the automatic control valve is also in the middle position, The oil from the pump flows directly back to the hydraulic tank, and the expansion brake is braking under the action of the spring force to maintain the normal working state of the ring to meet the production cycle.
