◎According to the end weight loading,the welding manipulator has many types:light duty type(LHQ),medium duty (LHZ),heavy duty(LHW),and super heavy duty(HCJ).
◎Sstructure:sationary,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 ratchrt structure,safe and reliable.
◎Boom end has cross-slides,which can be controlled thru manual pendant.
◎Control rooler 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.
