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

Welcome to our specialized machinery category for 3-inch hydraulic hose crimping machines, built specifically for heavy industrial assembly plants, mining equipment service centers, marine repair yards, and fluid power distributors. Engineered to process large-bore flexible hoses from 1/4" up to 3" inside diameter (DN75), this high-capacity series handles standard 1/2-wire steel braided hoses, industrial suction and discharge pipes, as well as heavy-duty 4-wire and 6-wire spiral hydraulic lines, including 4SP, 4SH, R13, and R15 configurations.

Engineered for High Tonnage, Opening Clearance, and Daily Production Runs

A reliable 3" hose crimper demands far more than basic hydraulic pressure. It requires a massive forged steel head block, wide die opening clearance, and balanced radial force distribution to crimp large industrial couplings and flange ends without die jamming or under-crimping. Available with an optional ultra-thin crimping head design, these machines easily accommodate complex elbow fittings, 90-degree flange tails, and compact hose assemblies. Built with heavy reinforced steel head units, precision-ground swaging dies, and heavy-duty hydraulic pumps, our machines deliver a consistent radial clamping force from 3600 kN to over 6000 kN. This rigid frame holds crimp dimensions repeatable down to 0.01 mm, preventing collar blow-offs or slow fluid weeping under high surge pressures.

• Broad Swaging Range: Effortlessly crimps 1/4" to 3" hydraulic hoses, industrial oil and chemical transfer hoses, water delivery pipes, and heavy steel flange fittings for both skive and no-skive ferrules.
• 6-Wire Spiral & Thin-Head Ready: Driven by high hydraulic cylinder force to collapse thick steel ferrules on heavy multi-spiral hoses, with thin-head geometry options for tight elbow clearance.
• Flexible Digital & Touchscreen Controls: Choose between digital display micro-adjusters for quick manual setup, or smart PLC touchscreen control panels that store crimp recipes, count production cycles, and automate batch operations.
• Custom Power Setups: Available in 380V or 220V 3-phase for high-speed shop production, as well as custom voltage motor options to match regional electrical supply standards.
• Complete Workshop Package: Every unit includes a full set of interchangeable swaging dies, an integrated 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 hydraulic hose production facility, maintain heavy earthmoving fleets, or assemble custom fluid lines for offshore platforms, our 3-inch hose crimper lineup delivers the daily operational reliability required across tough sectors:

1. Heavy construction, mining, and earthmoving machinery maintenance (large excavators, mining trucks, and mobile cranes).
2. Large-bore hydraulic hose assembly plants and OEM heavy machinery manufacturing lines.
3. Oil and gas extraction, marine engineering, and offshore fluid handling systems.
4. Agricultural machinery, forestry harvesters, and industrial factory fluid pipe servicing.
