Tight line describes the working principle and method of use

       gantry crane  industry has a single quarter from the fourth quarter, the market size has increased, but due to the large environmental impact, the overall market outlook is still not optimistic, so the fourth quarter,  bridge gantry crane  industry exports $ 622 million, fell 25.7 percent.

        2012 fourth quarter lifting machinery industry automation products market size of 936 million, the chain increased 81.8%, representing a decrease of 11.9%. In the fourth quarter, the highest amount of low-frequency applications, and the overall  hoist crane  industry automation applications for 41.0%, due to customers' automation products better brand recognition, brand usage of automation products is relatively stable.

        Tight line is laid in the construction of overhead lines as tension conductors. When used on the first tight line or galvanized wire rope loosen, and fixed in the cross arm with clamp pliers clamp the wires, and then pulled the special wrench. Since the anti-reverse pawl role gradually rope or wire grip zinc plated iron wire on the ratchet cylinder, the wires tightened. To tighten the wire fixing the insulator. Then loosen the pawl release the rope or galvanized wire, then release the clip pliers, and finally the wire rope or galvanized iron wire on the ratchet drum.

        Tight line can improve the process of lifting cargo security. Tight line applications: buildings, roads, bridges, metallurgical, mining, slope tunnels, wells and other infrastructure construction management protection of mechanical equipment.
