Automatic Ringlock Ledger Welding Machine for Scaffolding | MHD CNC, Jinan, China

The Automatic Scaffolding Ringlock Ledger Welding Machine automates the welding of ringlock ledgers, a job that has traditionally been done by hand. It is designed to improve the efficiency and safety of ringlock scaffold production.

The machine is controlled by a Siemens PLC and driven by two motors delivering 8Nm of torque. It welds at 36 degrees per second (equivalent to 6 rpm), at a weld voltage of 25V and a weld current of 200A. It handles 48.3mm diameter pipe in lengths from 500mm to 3,000mm, which covers the range of ledger lengths in a typical ringlock system.

MHD CNC says that welding ledgers by hand exposes workers to sparks, heat, and fumes, and that automating the process reduces labour cost, saves time, and lowers the risk of workplace injury.

Why Choose an Automatic Ledger Welder?

Ledgers are made in volume, and a ringlock system is only as good as its welds. Manual welding is slow and varies from worker to worker, and it exposes operators to hazards.

• Higher productivity. MHD CNC says factories can boost output by adopting a ledger welding machine.
• Lower labour cost. The machine performs the weld automatically instead of relying on skilled welders at each station.
• Safer for operators. Automation reduces exposure to sparks, heat, and fumes.
• Consistent welds. PLC control repeats the same weld parameters on every part.
• Wide length range. 500 to 3,000mm covers most ledger sizes in one machine.

Frequently Asked Questions

What does this machine do?
It automatically welds ringlock scaffold ledgers, replacing manual welding.

What pipe does it handle?
48.3mm diameter pipe, in lengths from 500mm to 3,000mm.

What control system does it use?
A Siemens PLC.

What are the welding parameters?
A weld voltage of 25V and weld current of 200A, at a welding speed of 36 degrees per second.

What are the safety benefits?
MHD CNC says automating the weld reduces workers' exposure to sparks, heat, and fumes compared with manual welding.

Does it need pre-marking like the base collar machine?
The page doesn't say. Ask MHD CNC how ledgers are set up and loaded.

Is financing or staged payment available?
Yes. A deposit secures your order and begins production, with the remaining balance due only once your machine has been built, inspected, and is ready to ship.

Should I buy new or used?
This model is available new, from a manufacturer that specialises in scaffolding production equipment.
