Active two-directional pressure injection for reliable full adhesion!
In areas where access is difficult and the boreholes cannot stand independently, the leg drill method using rope scaffolding has been widely used. In contrast, the "SP Leg Drill" actively employs "two-directional pressure injection," enabling the installation of permanent bolts up to 3.0 meters even in ground where the boreholes cannot stand independently. Additionally, this pressure injection can be applied for the repair of aging slope protection structures. 【Features】 - Economical short-length rock bolts for ground where boreholes cannot stand independently - Reliable anchoring achieved through pressure injection For more details, please contact us or download the catalog.
