Enerpac launches cordless rail stressing kit
The Enerpac RP-70A hydraulic rail stressor and ZC3-Series battery powered stressing pump provide a cordless, zero emission, rail stressor kit for rail track thermite welding.

Enerpac has released its RP-70A hydraulic rail stressor and ZC3-Series battery powered stressing pump which provides a cordless, lightweight, zero emission, rail stressor kit for rail track thermite welding.

Traditional fully assembled rail pullers are too heavy for operators to comfortably transport and deploy safely and quickly. The Enerpac RP70A stressor uses modular components that can be assembled and installed on site without the need for tools, making preparation for rail stressing easier and safer. Assembly typically takes less than two minutes.

The Enerpac rail stressing kit is designed for railway maintenance crews who assemble and install the rail puller directly on site when adjusting the gap between rail ends for rail stressing, rail welding, repairing rail failures and servicing insulators. The durable, simple assembly components, including Enerpac ZC3-Series pump and hose set, are up to three times lighter than similar tools. The complete kit can be transported in an optional specially designed steel transport frame.

The RP70A stressor has a 70-tonne pulling and 35-tonne pushing capacity while holding the rail in neutral length during the thermite welding process.
