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

Welcome to our premier product category for 4 inch hose crimping machines, specially designed for ultra-large industrial swaging applications and heavy-duty fluid transfer systems. Positioned directly under our primary hose crimping machine line, this high-tonnage series is built to process large-diameter industrial hoses, water delivery pipes, and high-pressure hydraulic hoses up to 4 inches (DN100) in internal diameter, including multi-spiral steel wire configurations.

Extreme Clamping Tonnage and Precision Control

Crimp-fitting large-bore 4-inch hoses requires enormous structural rigidity and immense hydraulic force to guarantee zero-leak, permanent coupling attachments under severe operating pressure. Constructed with massive forged steel head frames and reinforced high-pressure hydraulic cylinders, every 4" hose crimping machine provides exceptional clamping forces, often exceeding 4000 kN to 5000 kN. Equipped with digital micro-adjusters or advanced PLC touch-screen controllers, operators can achieve exact crimp diameters with strict repeatability down to 0.01 mm.

• Ultra-Large Capacity: Seamlessly handles industrial rubber hoses, chemical transfer lines, oil suction pipes, and heavy hydraulic hoses up to 4" (DN100).
• High-Rigidity Structure: Heavy-duty forged cylinder block designed for continuous high-load operations in heavy manufacturing plants.
• Complete Die Sets & Storage Rack: Supplied with durable interchangeable quick-change die sets, a specialized storage cabinet, and a foot switch for hands-free operation.
• Custom Electrical Setup: Configurable in 380V three-phase, 220V, or customized voltages to meet global industrial power standards.

Versatile Applications in Heavy Industry

Due to their outstanding pressing capability and wide jaw opening, our 4-inch hose crimping machines are widely utilized across demanding industrial sectors, including:

1. Oil and gas extraction, refinery fluid transfer, and offshore marine engineering.
2. Large-scale mining, heavy construction, and dredging equipment maintenance.
3. Industrial plant fluid power assembly and chemical pipeline fabrication.
4. Port machinery, shipbuilding, and heavy-duty hydraulic repair centers.
