Hydraulic hose crimping machines

A hydraulic hose crimping machine is a specialized device used to permanently and securely connect hydraulic hoses with fittings. It enables quick and reliable in-house production or repair of hydraulic lines in workshops, industrial environments and service vehicles. By applying high hydraulic pressure (1,000–1,450 kN of crimping force), a strong, form-fitting and friction-locking connection is created, capable of withstanding high operating pressures and pulsation loads.

There are two main types:

• Stationary workshop crimpers: Designed for fixed installation, usually offering higher crimping force, greater weight and electric drive
• Mobile crimpers: For flexible on-site use, equipped with hand, foot or pneumatic pumps

They differ in crimping force, maximum hose diameter, crimp range and type of control.

Crimp dies are tool inserts designed for specific hose diameters. They must match the hose and crimp dimension exactly to ensure a secure and reliable connection. Some mobile crimpers come with die sets included, while for larger workshop crimpers dies often need to be purchased separately.

Typical specifications include:

• Crimping force: 1,000–1,450 kN
• Maximum hose size: up to 1 1/4" (2SN) or 1" (4SH/4SP)
• Crimp range: approx. 4 mm to 61 mm
• Drive: Electric, hand or foot pump with 700 bar pressure
• Adjustment: Stepless, typically via micrometer screw with LED display
• Weight: 25 kg (mobile) to 93 kg (stationary)

• Fast on-site repairs
• Minimized downtime
• Increased operational safety due to precise crimping
• Long-term cost savings
• Customized hose lengths and types

• Strict adherence to manufacturer specifications
• Precise crimping machine adjustment to the correct crimp dimension
• Use of compatible components (hose, fitting, ferrule)
• Careful working method
• Avoiding under- or over-crimping

Yes, bundle packages often include:

• Mobile crimping machine
• Matching crimp dies
• Various hydraulic hoses
• Ferrules and fittings

These bundles offer a ready-to-use solution and are often shipped free of charge.

1. Determine the crimp dimension (select hose & fitting, obtain values from chart)
2. Install the appropriate crimp dies
3. Pre-assemble the fittings
4. Set the crimping machine precisely
5. Crimp the hose until the target dimension is reached
6. Check using gauge pin & caliper

Deviations from the specified crimp dimension result in safety risks.
