Heavy-Duty 3 Inch Hose Crimping Machines for Industrial & High-Pressure Assemblies

Welcome to our specialized product category for 3 inch hose crimping machines, designed specifically for heavy-duty industrial swaging operations and large-bore fluid power systems. Positioned directly under our main hose crimping machine line, this high-capacity series is built to crimp large-diameter flexible hoses up to 3 inches (DN75) in internal diameter, including high-pressure 4-wire (4SP/4SH) and 6-spiral hydraulic hose assemblies.

Unrivaled Clamping Power and Micrometric Precision

Processing a 3-inch industrial or hydraulic hose requires an exceptionally strong mechanical structure and massive hydraulic force to ensure leak-proof, permanent coupling attachments. Engineered with heavy-duty forged steel head units and reinforced hydraulic cylinders, each 3" hose crimping machine delivers high clamping force ranging from 2800 kN to over 3600 kN. Integrated with precision digital micro-adjusters or touch-screen PLC control systems, operators can consistently achieve exact crimping dimensions with repeatability down to 0.01 mm.

• Broad Working Range: Handles a versatile range of industrial rubber hoses, water delivery pipes, and heavy hydraulic hoses from 1/4" up to 3" (DN75).
• Reinforced Heavy-Duty Frame: Built for continuous high-load service in demanding factory production lines and large repair workshops.
• Complete Die Set Kit & Cabinet: Equipped with standard quick-change interchangeable die sets, an integrated die rack cabinet, and a convenient foot pedal for hands-free control.
• Custom Electrical Configurations: Available in 380V three-phase, 220V single-phase, or custom voltage options to match global industrial standards.

Versatile Applications Across Heavy Industries

Because of their superior power and large opening capacity, our 3-inch hose crimping machines are widely deployed across challenging industrial sectors, including:

1. Heavy construction, mining, and earthmoving equipment maintenance.
2. Large hydraulic hose assembly plants and OEM machinery manufacturing.
3. Oil and gas extraction, marine engineering, and offshore fluid handling.
4. Agricultural, forestry, and heavy industrial plant fluid pipe servicing.
