The Principle Of Ratchet Tie-down Strap

The normal operation of the belt conveyor must make the conveyor belt have a certain tension. The equipment that provides the tension is the ratchet tie down strap. The so-called "tightening" has the meaning of absorbing the elongation of the conveyor belt and providing tension to the conveyor belt.

The screw tensioning device is generally adjusted manually by a screw or by a small hydraulic cylinder to lock and fix the device after reaching the required tensioning force. The screw tensioning device is generally placed on the tailstock of the belt conveyor, and the tail roller is used as the tensioning roller. When the head roller is used as a tension roller, the screw tensioning device is placed on the head frame. Spiral tensioning is characterized by a simple structure and compact layout. However, the manual adjustment of the spiral tensioning force and stroke is small, and the adjustment of the tensioning force is operated based on experience and observation of the state of the conveyor belt. The pre-tension cannot be automatically kept constant, and it needs to be adjusted frequently. Belt conveyors are generally used in small belt conveyors and equipment.

The fixed electric winch tensioning device is a form in which the tensioning force of the tensioning drum is adjusted by the electric winch. The electric winch is connected to the tension trolley of the tension drum through the pulley block, and the tension value is adjusted by the display of the load cell. The setting of the tensioning force needs to meet the tension requirements of the conveyor under various working conditions, and the tensioning force of the electric winch tensioning device is calculated according to the most unfavorable working conditions. The fixed electric winch is adjusted according to the set tension value in the stopped state. Generally, there will be a ratchet strap manufacturer to cooperate with.
