Suitable for a range of crimping sizes
This hydraulic hose crimper machine can be used in repair workshops and mobile service vans. Its compact design and greaseless production crimp technology make it ideal for on-site repairs.
To check that the crimp is successful, simply look at the chalk mark. If it is no longer at the base of the fitting, this indicates that there was movement during the crimping process.
Crimping Process
The crimping process for hydraulic hoses is an essential step for ensuring a tight, safe connection between the hose and its fitting. The process involves using a power tool with dies that are compatible with the hose’s size and working type. Before crimping, the hose must be cut to the correct length and cleaned. It is also important to select the matched fitting and mark its insertion point. After crimping, the hose should be visually inspected for any gaps or other defects.
Having a reliable hydraulic hose crimping machine in your shop saves you the cost of having to travel out of your way to have your hoses crimped at another location. Many businesses choose to keep their own crimping machines on site to ensure they have the equipment needed to quickly assemble and deliver the fluids and gases necessary for operation. The crimping process is simple: place the hose end into the cylinder, turn on the machine and leave it running until the crimped part of the fitting is completely closed.
Safety Measures
From airplanes to snow plows, hydraulic hose assemblies are responsible for carrying fluids in high pressures and temperatures. They also must withstand the flexing and vibrations of daily use. Proper crimping will prevent a loss of performance and eliminate costly damage and downtime.
Before working with a hydraulic hose crimping machine, it’s important to perform a risk assessment and follow safety precautions. Ensure the crimper is on a stable work surface and that only trained and authorised personnel are permitted to operate it. Also, be sure to use a lockout tagout procedure, where the equipment is turned off and power is disconnected before someone starts working on it.
Keep in mind that hoses can elongate up to 2% and contract up to 4% during pressurisation, which can cause them to rupture and release a dangerous amount of hot oil. Also, be sure to avoid excessive bending, which can strain the reinforcement wires and reduce the hose’s ability to withstand pressure.
Machines Available
There are a variety of hydraulic hose crimping machines available for different applications. These devices crimp metal fittings to a hose’s outer diameter, creating a strong-hold union that resists leaks and cracking. They are also easy to use when compared with other crimping methods.
A hose crimping machine features a hydraulic pump that provides pressure to the die, a control handle, and a removable die. The dies are specific to a certain type of hose and crimping size, and they can be interchanged as needed.
Flowfit’s portable ET1000 crimp machine is an excellent choice for mobile field use, as it is air/hydraulic powered and can be used on 120v AC power or compressed gas. The machine is easy to set up and operate, and it includes a portable stand pre-drilled for mounting to a workbench or tabletop. It is capable of crimping a wide range of hose sizes and types, including -20 braided and 2 inch four spiral hoses. It also comes with a programmable electronic keypad with 10 presets for common crimping styles and sizes.
Maintenance
A crimping machine is a large investment that saves your company money in the long run by eliminating costly downtime caused by failing hoses. But crimpers also require proper care to ensure accurate and consistent crimps.
For the optimum performance of your hydraulic hose crimping machine, you should drain and refill the oil reservoir every 1,000 hours. In addition, a good maintenance routine includes weekly inspections of the dies and crimp bowl to check for signs of wear, such as tight bends or kinks.
You should use Enerpac lubricant and follow the recommended fill and drain intervals. You should also clean the crimp bowl and apply approved lithium grease to the dies on a regular basis. Hydraulic crimping machines are made of many different parts and materials, so it is important to choose quality equipment that you can depend on. For instance, some suppliers may try to reduce costs by using low-quality parts or material, which can result in a substandard crimp.
