stationary,stationary and revolve ,moving and revolve;Cross-section of boom and column is calculated scientifically. - details see: https://www.machineto.com/light-duty-type-auto-welding-manipulator-10200524

*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)

*stucture: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 ratchet6 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.
