Shandong Zhongji Luyuan Machinery Co., Ltd. presents the Telescopic pile cage welding machine LYGH-1600T, a fully automated CNC equipment designed to revolutionize your rebar cage fabrication process. This enterprise-grade system handles cage diameters from 400 to 1600 mm with telescopic length adjustment from 1 to 18 meters, delivering production efficiency of 8 sections per 10-hour shift. With main bar capacity of φ16–40 mm and spiral bar diameter of φ6–16 mm, the machine eliminates traditional manual welding inconsistencies while reducing your labor dependency by up to 75%. Equipped with PLC touch screen control and automatic double-gun welding, this machine ensures uniform weld quality and precise pitch control critical for load-bearing structures in seismic zones and high-rise construction projects.
You face three major challenges in pile cage production: geometric inconsistency from manual work, rising skilled labor costs, and structural integrity concerns. Our solution addresses each directly.
The telescopic design allows you to produce cages ranging from short 1-meter sections to extended 18-meter lengths without changing equipment. This flexibility means you operate one machine across multiple project specifications—from bridge piers to deep basement foundations—maximizing your capital equipment utilization.
Your production yard benefits from the compact 20 m × 6 m footprint. Unlike traditional fixed-length systems requiring extensive space, this machine adapts to limited construction sites while maintaining full operational capability.
The fully automatic welding system with top-mounted double guns delivers consistent penetration and shear strength compliance. You achieve ASTM and international code requirements automatically, reducing inspection failures and rework costs significantly.

Telescopic Body for Multiple Applications
You invest once and serve diverse project needs. The adjustable length mechanism handles variable-depth pile foundations without purchasing separate equipment for each specification.
Minimal Space Requirements
Your construction yard gains operational flexibility. The compact design allows installation in confined urban sites or easy relocation between project phases, reducing mobilization costs.
Fully Automatic Welding Stability
You eliminate operator skill variance. The automated system maintains consistent weld quality across entire production runs, ensuring every cage meets engineering specifications without manual intervention.
Rapid Specification Changes
You respond to engineering modifications quickly. The PLC control system allows diameter and pitch adjustments in minutes rather than hours, keeping your production schedule on track when design changes occur.

High-Speed Rail Viaduct Construction
You need thousands of standardized cages with exact diameter consistency for high-speed stability. The Telescopic pile cage welding machine LYGH-1600T operates in centralized prefab yards, delivering uniform quality across massive production volumes required for rail infrastructure.
Maritime and Bridge Foundations
Your projects demand thicker rebar for saltwater-resistant structures. The equipment handles up to φ40 mm main bars while maintaining precision in humid coastal environments where corrosion protection is critical.
Urban Deep Basement Development
You're working with limited site footprints for skyscraper foundations. The telescopic efficiency enables rapid production of deep-pile cages exceeding 50 meters (when coupled) within restricted urban construction zones, accelerating your project timeline.
Tunnel and Underground Utility Corridors
Your specifications require variable-length cages for different geological conditions. The adjustable system produces custom lengths matching exact engineering requirements without tooling changes.

You need confidence in equipment performance before investment. Our quality control process focuses on five critical dimensions:
Concentricity Testing
Rotating faceplates maintain axial deviation below 3 mm, preventing cage wobble during welding that could compromise structural integrity.
Weld Penetration Verification
Automated welding spots undergo pull testing to validate shear strength compliance with ASTM and Eurocode standards, ensuring load-bearing capacity.
PLC Logic Validation
Emergency stop response and pitch adjustment accuracy are tested under load conditions, guaranteeing operator safety and production reliability.
Hydraulic Stability Inspection
Support rollers maintain levelness across full telescopic extension, preventing deflection issues that affect cage geometry.
Electrical Safety Certification
Insulation and grounding tests ensure safe operation in outdoor construction environments where moisture and dust are present.

Q: What rebar diameters can the LYGH-1600T process?
A: The machine handles main longitudinal bars from φ16 mm to φ40 mm and spiral winding wire from φ6 mm to φ12 mm as standard. Custom configurations accommodate thicker bars based on your specific engineering requirements.
Q: Does it support different welding methods?
A: Yes. The universal mounting bracket accommodates both automated CO2 shielded welding torches for standard production and manual welding stations when you need specialized reinforcement hooks or non-standard connections.
Q: How does the telescopic feature reduce logistics costs?
A: The support frame retracts for transport, fitting into standard 40-foot high-cube containers. This reduces your international shipping expenses and simplifies domestic transportation between project sites.
Q: What production capacity should I expect?
A: A single shift produces 15-25 cages depending on complexity and specifications. This represents 3-4 times the output of manual crews while maintaining superior quality consistency.
Q: What maintenance does the control system require?
A: You should perform weekly PLC program backups and daily encoder alignment checks. Dust-sensitive electrical cabinets need regular inspection in outdoor environments to ensure zero-downtime performance.
Q: Can the machine handle custom cage lengths beyond 18 meters?
A: Yes. While standard configuration reaches 18 meters, we provide customization for longer cages through coupling systems or extended frame designs based on your foundation engineering specifications.

The Telescopic pile cage welding machine LYGH-1600T delivers measurable improvements in production efficiency, quality consistency, and operational flexibility for your foundation projects.
