Work can be done from a height of 4.5 meters! Work efficiency has significantly improved.

The low-headroom all-casing (full rotation) sliding method has made it possible to work in low-headroom conditions of 4.5 meters, where heavy machinery could not previously enter, significantly improving work efficiency. It adopts a telescopic sliding arm that extends up to 9 meters, allowing work even in narrow sites, making it ideal for tasks inside buildings and under highway girders that were impossible with conventional methods. By employing the full rotation all-casing method, it allows for excellent excavation by pre-inserting the casing tube and rotating it. 【Features】 ○ Work possible from a headroom of 4.5 meters ○ Method enabling low-headroom work ○ Sliding type adapted to the site ○ Reliable all-casing method ○ Significantly improved work efficiency For more details, please contact us or download the catalog.
