Heavy-Duty 4 Inch Hose Crimping Machines for Large-Bore Industrial Assemblies

Welcome to our specialized machinery category for 4-inch hydraulic and industrial hose crimping machines, engineered for high-tonnage swaging operations, chemical processing plants, offshore platforms, and heavy equipment manufacturing. Built with a heavy-duty head opening, this machine processes industrial rubber hoses up to 4 inches (DN100), high-pressure 4-wire spiral hydraulic hoses up to 4 inches, and ultra-high-pressure 6-wire spiral hydraulic lines up to 3 inches (DN75).

Built for High Tonnage, Large Jaw Clearance, and Daily Industrial Service

Crimp-fitting large-bore industrial hoses and multi-spiral hydraulic lines demands exceptional structural rigidity and immense hydraulic force to guarantee permanent, zero-leak coupling attachments under extreme system pressures. Featuring heavy forged steel head frames, wide radial die opening clearance, and reinforced hydraulic cylinders, our 4-inch crimpers deliver high radial clamping forces ranging from 4000 kN to over 6000 kN. This rigid frame easily accommodates thick industrial couplings, 90-degree flange tails, and heavy ferrules while holding crimp dimensions repeatable down to 0.01 mm.

• Broad Swaging Capability: Swages industrial suction and discharge hoses up to 4", 4-wire spiral hydraulic hoses up to 4", and heavy 6-wire spiral lines (such as R15 and 6SH) up to 3" for both skive and no-skive ferrules.
• Multi-Spiral & Large Flange Ready: Driven by high cylinder force to collapse thick steel ferrules on heavy multi-spiral hoses with generous die retraction clearance for large elbow fittings.
• Practical Control Options: Choose between digital display micro-adjusters for quick manual setup and caliper verification, or smart PLC touchscreen control panels that store crimp recipes, count production runs, and automate batch operations.
• Custom Power Options: Available in 380V or 220V 3-phase for fast shop production, as well as custom voltage motor setups to match regional electrical supply standards.
• Complete Workshop Package: Every machine includes a full set of interchangeable swaging dies, a specialized die storage rack cabinet, a quick-change tool for fast die swaps, and an ergonomic foot pedal for hands-free operation.

Versatile Applications Across Demanding Global Industries

Whether you operate a large-bore industrial hose assembly facility, manage heavy marine repair docks, or supply custom fluid transfer lines for oilfield operations, our 4-inch hose crimper range delivers the daily operational reliability required across tough sectors:

1. Oil and gas extraction, refinery fluid transfer lines, chemical handling, and offshore marine engineering.
2. Large-scale mining equipment, heavy construction machinery, dredging pipe servicing, and port cranes.
3. Industrial plant fluid power assembly, chemical pipeline fabrication, and bulk material handling.
4. Shipbuilding yards, marine engineering workshops, and heavy-duty hydraulic repair centers.
