Performance Features of the Wheelset Press:
- Automatically mount the 2 wheels on the same axle simultanously without turning the axle and in a sequence first the wheel at one side of the axle then the wheel at the other side
- Automatically control the inner distance and wheel position tolerance.
- Adopt Siemens S7-300 PLC and AdvanTech Industrial computer to control and achieve the fully automatic pressing operation.
- Both automatic and manual mode are available for option.
- The wheelset press can track and control the whole process, detect the pressing condition of the
wheelset, and analyze and process it through industrial computer. It can export the pressure vs displacement curve and other results onto the screen and printer. - The measurement unit will automatically detect and collect the relevant data and display it on the screen.
- Automatic recording of mounting curve, radial and axial run-out and back pressure test of each mounted component;
- Overall gantry frame structure, with high strength, good rigidity and less deformation.
- Movable resistant column.
- Double ram cylinder pressing.
- Unique Invention patented cylindrical ram for wheel mounting, with high pressing accuracy.
- Special patented centring mechanisms for center hole positioning.
- Standard roll-in or pass-through design.
- Applicable to the wheelset with standard, narrow, meter and board gauge.
Overview of Hubei Heqiang:
Hubei Heqiang Machinery is the leading manufacturer of wheel set press machines in China. It offers the most advanced wheel set pressing equipment available in the railway and other relevant industry. The wheelset presses are used to mount and dismount all of the elements on the axle (wheel discs, brake discs, gears and bearings). With both single and double cylinder version available for option and capacity range from 200 to 800 tons. Our vast range of machines can satisfy all customer requirements in both maintenance and mass production applications.
Our fully automatic double cyliner wheelset press is the most advanced wheel press machine available on the market today. Available in capacity ranging from 200 to 500 tons. This machine features a precisely positioned cylinder on each side of the machine along with our state-of-the-art measuring system that utilizes a high-tech servo system and a series of analog laser measuring devices to position each wheel-set component with high precision. All tooling is specialized and easily exchanged to safely accommodate a large variety of wheel set components and configurations. A rotation device are optional to be supplied with the machine to perform wheel back-to-back, axial run-out and radial run-out measurements after the mounting process has been completed.
Warranty & After-sale Service:
One year of free warranty and lifetime maintenance for the equipment for your purchased equipment. During the warranty period, only due to design defects, manufacturing quality, and quality of purchased parts, our company is responsible for free maintenance. The company provides the required replacement parts (except for consumable parts). Over the warranty period, repairs only are charged at the cost price. At the same time, you will enjoy a lifetime software upgrade from the date of purchase; our engineers will provide a quick response when service is required.
