Key Product Features
1. Large-Capacity Structural Slicing
Specifically engineered to accommodate structural profiles up to 800mm width. This makes the G 60 80S highly valuable for pre-fabrication yards, bridge builders, civil construction projects, and large structural steel suppliers.
2. Rigid Double-Column Portal Frame
The main sawing frame moves vertically along twin precision guide columns. Symmetrical portal layout balances frame load during vertical feed, eliminating frame flexing and ensuring straight, square cut faces across wide structural components.
3. VFD Variable Blade Speed Regulation
A vector-controlled Variable Frequency Drive allows stepless regulation of the 41mm blade speed from 20 to 90 m/min via the operator control station, matching the blade velocity to structural shapes.
4. Proportional Hydraulic Downfeed Control
Features a dual-acting hydraulic feed cylinder with a micro-adjustable downfeed dial. This allows precise regulation of feed rate and cutting pressure to optimize teeth penetration on structural profiles.
5. Full-Stroke Hydraulic Clamping Vise
The workpiece is clamped securely by a full-stroke hydraulic vise. The full-stroke design allows fast and rigid clamping of various profile widths without needing manual adjustment blocks.
6. Recirculating Flood Coolant System
An integrated coolant pump directs recirculated fluid to both carbide guide blocks to lubricate the cut and flush chips away, extending blade life and preventing work hardening of the cut face.
Industrial Applications
The G 60 80S is a heavy-duty, large-capacity solution for primary structural steel sawing:
Large-Scale Structural Steel Yards
Perfect for processing large structural columns, H-beams, structural channels, and steel angles for frame buildings and architectural steel designs.
Bridge & Infrastructure Construction
Accurately cuts thick-walled steel pipes, heavy structural profiles, and solid steel bars with weld-ready edges.
Steel Distribution Yards
Allows steel stockholders to process massive bundles of pipes and large solid steel bars to custom lengths with semi-automatic efficiency.
Frequently Asked Questions
1. Why is a double-column gantry design superior to a hinge-pivot (scissor) saw for structural steel?
A pivot saw descends at an angle, which can cause blade deflection and uneven wear when cutting wide structural shapes. The double-column portal saw descends vertically, maintaining uniform tooth load across the cut section. This translates to straight cuts and much longer blade life.
2. Can the G 60 80S handle bundle cutting?
Yes. We offer optional hydraulic vertical nesting clamps that can be integrated with the main clamping vise, allowing vertical bundle cutting of structural profiles or pipes up to the machine's capacity envelope.
3. What is the typical blade lifetime when cutting heavy structural H-beams?
With proper blade speed matching (using VFD) and flood coolant, a high-quality bimetal blade typically achieves 15,000 to 20,000 square centimeters of cutting. Hardened structural steel may reduce this slightly, but correct feed pressure adjustments extend blade life.
4. What are the packaging, delivery lead times, and warranty parameters?
Due to its heavy weight (3,200 kg), the G 60 80S is shipped in heavy seaworthy export packaging. Standard models have a lead time of 30 to 45 days. The saw is covered by a 1-year B2B industrial warranty.
