Product Summary
The Model 40AO Rebar Auto Threading Machine is designed for on-site threading of rebar diameters from 16mm to 40mm. With a powerful main motor (5.5KW/7.5KW at 1450RPM) and dual speed options (1:23 quick / 1:29 slow), it delivers consistent threads for rebar coupler systems. Equipped with pneumatic clamping (0.4-0.8MPA), it ensures secure bar holding during threading. The machine supports max threading lengths of 90mm with block and 150mm without block, adapting to various splice requirements. Ideal for high-rise buildings, airports, high-speed railway stations, and large bridges.
