Lightweight, portable, with undermount and overmount options

Enerpac has announced the launch of the new RP70A2L Rail Stressor, expanding its Modular Rail Stressor range with a lightweight, versatile solution that offers undermount and overmount options, and longer stroke tailored for European and international use. All models in the RP70A-Series help crews reduce manual handling, speed up setup, and when paired with a ZC-Series hydraulic pump provide a zero-emissions rail stressing solution.

Far lighter than comparable designs, the Modular Rail Stressor range features rugged, portable components that can be easily carried by one or two people. High-strength steel parts and aluminium cylinders provide an optimal balance of durability and portability. The modular design also makes transporting equipment to remote work locations simpler, helping crews deploy the system quickly while reducing the physical demands of handling heavy rail stressing equipment.

Fast setup is essential when working within restricted rail possessions, and the RP70A2L has been designed to minimise preparation time. Fast and simple on-site assembly is enabled by automatic locking arms, clamps, and grippers - with no extra tools required. You're ready to pull rail in a matter of minutes. By reducing assembly complexity, maintenance teams can spend less time preparing equipment and more time completing critical rail stressing operations safely and efficiently.

Rail infrastructure maintenance requirements according to regional needs and types of application, making versatility an increasingly important consideration for contractors and infrastructure owners. Choose above- or below-rail mounting to meet the requirements of different rail infrastructure managers and applications. The RP70A2L helps crews adapt to a wider range of projects, with a single tool, while meeting regional compliance requirements.

The RP70A2L builds upon a proven engineering heritage that has already demonstrated its reliability in demanding rail environments.

Based on the proven RP70A platform, this new model builds on a design trusted by the UK's Network Rail, the UK's rail infrastructure operator, with more than 270 systems already in operation. The new RP70A2L undermount version extends the series with broader regional flexibility, supporting use across a wider range of international rail networks.

This established foundation provides customers with confidence that the latest addition to the range delivers the same levels of safety, durability, and performance while expanding the applications the system can support.

As rail operators continue to reduce emissions and improve sustainability, battery-powered hydraulic technology is becoming an increasingly attractive alternative to traditional power sources.

Compatible with the cordless Enerpac ZC-Series hydraulic pump models ZC3404JE-RS and ZC3404JB-RS, the new undermount and overmount rail stressors deliver a zero-emission rail stressing solution, reducing environmental impact while maintaining full performance in demanding conditions. Enerpac's ZC-Series is quickly becoming the go-to solution in the field, delivering reliable, high-performance power for faster, cleaner, and quieter rail stressing operations

Together, the RP70A2L and Enerpac ZC-Series pumps provide rail maintenance teams with a complete solution that combines portability, productivity, and sustainable performance for modern railway infrastructure projects.
