CNC Pile Cage Welding Machine — New | GUTE, Chengdu, China | Machine Matcher

The CNC Pile Cage Welding Machine (Steel Cage Welder) is an automatic welding system for producing construction concrete pile cages and rebar cages, used extensively in foundation piling for bridges, high-rise buildings, and other deep foundation construction projects. The machine automatically feeds, winds, and welds spiral coil bar around a main frame bar structure to form a complete cylindrical rebar cage in one continuous process.

GUTE offers this machine across three models — SGH15-12, SGH20-12, and SGH22-12 — covering cage diameters from 300mm up to 2200mm, allowing buyers to select the right machine based on the pile cage sizes their projects require. Each model uses a PLC control system with touch screen and inverter, automatic wire feeding with online-adjustable spacing, and hydraulic feed rollers designed to prevent the steel cage deforming under its own weight during production.

Why Choose an Automatic Pile Cage Welding Machine?

Producing rebar cages manually — positioning spiral coil bar and welding it by hand around a main frame — is slow, labor-intensive, and prone to inconsistent spacing and weld quality. GUTE's CNC Pile Cage Welding Machine automates this entire process: automatic wire feeding with online spacing adjustment ensures precise, consistent coil spacing with minimal error, while frequency-controlled drag cage mechanisms maintain high running accuracy throughout production.

The machine's template system — using a template ring plus catheter combination — allows quick changeover to adjust the quantity of main steel cage wires, giving fabricators flexibility to produce different cage specifications without extensive retooling. Straightening systems built from high-strength alloy material further improve durability and extend the working life of wearing parts.

Frequently Asked Questions

What's the difference between the three models?
The SGH15-12, SGH20-12, and SGH22-12 differ primarily in maximum cage pile diameter — 1500mm, 2000mm, and 2200mm respectively — allowing buyers to select the model matching the largest cage diameter their projects require.

What cage lengths can this machine produce?
All three models produce cages from 3m up to 12m in length, with customization available for different length requirements.

What welding method does this machine use?
The machine uses carbon dioxide shielded welding, available in both manual and automatic welding modes.

How does the machine prevent cage deformation during production?
Multiple automatic hydraulic feed rollers support the cage structure during winding and welding, preventing deformation caused by the cage's own weight as it's produced.

Can this machine handle different main wire quantities?
Yes. The template ring plus catheter combination system can be quickly changed to adjust the quantity of main steel cage wires used.

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, backed by CE and ISO 9001:2000 certification.
