welding manipulator

According to the boom end weight loading, the welding manipulator has many types: light duty type(LHQ),medium duty(LHZ),heavy duty(LHW),and super heavy duty(HCJ) Structure: stationary, stationary and revolve, moving and revolve. Cross-section of boom and column is calculated scientifically. Drooping of boom along Horizontal travel is 2mm/m. Boom lifting device has anti-falling device, of ratchet structure, safe and reliable. Boom end has cross-slides, which can be controlled thru manual pendant. Control roller has eccentric shaft ,which can decrease clearance between roller and rail. Column revolve unit has motor-driven and manual drive. Control unit includes control board and pendant, interface with positioner and turning rolls also prepared.
