H-Type-2 500-2000kg Three Axis Vertical Tilt Welding Positioner for Robot Cells

H-Type-2 Three Axis Vertical Tilt Welding Positioner for 500-2000kg Parts

The GBS-02-H500-2, H1000-2 and H2000-2 are three axis vertical tilt positioners for workpieces that are too heavy to turn by crane between welds. Three servo axes work together: a vertical tilt that stands the part on edge, a rotation that presents each side to the torch, and a third axis that corrects the angle of the fixture so the seam stays flat. Payload classes are 500kg, 1000kg and 2000kg, positioning accuracy is ≤1arcmin, table height is 800mm as standard, and the whole assembly is protected to IP65 against spatter and dust. Because all three axes can be configured as external axes of the robot, the programmer coordinates part motion with the torch path instead of stopping to re-clamp. That is the practical value of an H-type-2 robot positioner in a heavy welding cell: the part is turned by the machine, not by an operator with a pendant, so arc-on time and weld consistency both improve.

Technical Specifications

Advantages in Heavy Fabrication

• No crane turning: the three axis vertical tilt positioner rolls a 2000kg part without a lifting operation between passes.
• Flat-position welding: the third axis trims the fixture angle so the seam stays horizontal as the part turns.
• Coordinated motion: all axes run as robot external axes, so the torch path and part motion are one program.
• Rigid frame: a heavy H base and preloaded bearings hold ≤1arcmin accuracy under offset loads.
• Protected drive: IP65 sealing and a dedicated earth brush protect the gear train and feedback from weld current.

Typical Applications

• Construction and earthmoving equipment frames
• Heavy vehicle chassis and axle housings
• Pressure vessels and large tank sections
• Wind power components and gearbox housings
• Crane and conveyor structural assemblies

Frequently Asked Questions

Q: Why three axes instead of two?
A two axis unit tilts and rotates, but the seam angle changes as the part turns. The three axis vertical tilt positioner adds an axis that corrects that angle continuously, which matters on thick-section welds where position affects penetration.

Q: Can a 500-2000kg heavy welding turntable be installed on an existing floor?
Usually yes, subject to a foundation check. We supply anchor loads and a base plate drawing, and recommend a reinforced pad for the 2000kg model when the slab is thin.

Q: How are the three axes coordinated with the robot?
They are mapped as external axes in the robot controller and driven in the same program as the torch. Safety interlocks stop all axes when the cell gate opens.

Q: What is the delivery time for a custom configuration?
Standard models ship in 25-45 working days. Larger tables, special fixture interfaces or extended heights are quoted after drawing approval.

Production and Support

Gongboshi Robot Technology builds heavy positioners and robot external axes in Shanghai, with more than 100 engineers and projects across aerospace, nuclear, chemical, automotive and new energy since 2016. Frames are stress relieved and machined, assemblies are run in under rated load, and each H-type-2 robot positioner ships with test records, foundation drawings and a 12-month warranty backed by remote commissioning support.
