B. The tightening device has high tensile strength; the tensioning prestress is large. The ratcheting device for ratcheting transportation is mechanically tensioned with a ratchet, which is easy to use. The prestress of the ratcheting transportation device can reach 5000kg. It can bind goods firmly, which is impossible to hold rope; the width of the tightening device is 25mm to 75mm, and the contact surface with the goods is larger, which can effectively protect the goods; the tightening device can quickly load and unload the goods, saving Time, increase rate.
Because of this, most of the world began to gradually abandon the rope as early as 30 years ago, and the tie-down device has been widely used in various countries in the world in the late 1980s.
