Description

For the tough jobs, this ultra-compact Stierli-Bieger 420 Hybrid Ram Bender is your most powerful choice. We’re proud of a strong tool holder that spans 60mm, with a depth of up to 100mm, allowing for up 130mm tools. This machine features a very large working plate for efficient positioning of bent parts. The central bending pin holder is reinforced by a hardened steel brushing. Three further holes create plug-in pins for pipe bending or straightening tools. Also featured are a no-maintenance oil-lubricated guided cylinder, and complete hydro-mechanic stroke restriction. Solid steel construction ensures this bender can stand up to the rigors of all your applications. The stroke limitation operates electro-hydraulically with the unique Stierli switch-off system with Vernier scale and 0 mark. Operate it with the foot switch or special manual control cable, which features two modes and a straightening function.
