LD type series of button heading machine is a special equipment for concrete electric pole production used to upset head for steel wire. It can head high tensile steel wire with the nominal diameter of 4.6mm, 4.8mm, 5mm,6mm and 7mm. The diameter of upper heading is more than 1.5 times than the one of the steel wire. The use of hydraulic heading, hydraulic return in LD200C,LD300,LD400A,LD600 raises the return speed of the heading. AS all sliding seals use the Gled Ring and step seal as seals, the sealed effect is better, and the bearing capacity is higher, what's more, the resistance to wear gets better, the maintenance cost is very low and the service life is longer. The two-body design of heading mold facilitates the change of parts and improve the durability.
