RATCHET TIE DOWN is used to hold goods in place during transportation, movement, shipment or storage. They have locked, will not fall off, safe and reliable, light, easy to operate, protect objects from damage. It is to strengthen the steel template and compression board equipment, mainly play a tightening role. Common tensioning devices and use methods are as follows:
1. Screw tension device. The screw tension device is simple in structure, the tension stroke is too small, only suitable for short distance conveyor, generally less than 80m when the length is selected, the disadvantage is that when the belt stretches itself, it can not automatically tighten.
2. Gravity tension device. Gravity tensioning device is characterized by constant tensioning force and variable tensioning displacement. It is suitable for fixed long-distance transport aircraft. Its advantage is high safety and reliability, but its disadvantage is that the tensioning force can not be adjusted and the space requirement is large.
3. Fix the winch tension device. Fixed winch tensioning device is the use of small winch to tensioning, Ratchet Tie Down Straps winch generally use worm gear and worm reducer to drive the drum to wind steel rope, so as to tighten the tape. This tension device has the advantages of small volume and large tension, so it is widely used in underground belt conveyor.
4. Automatic tension device. The automatic tension device can not only adjust the tension force automatically according to the traction force of the active roller, but also compensate the elongation of the tape. Automatic tension device composed of motor, brake, reducer, drum, etc, adopting large tensile tensioning belt tensioning device, equipped with tension sensor at the same time, the determination of conveyor belt tension, change when the conveyor belt tension, beyond the scope of conveyor running, automatic tensioning device action quickly and adjust the conveyer belt tension, ensure the normal operation of conveyor.
