OverviewGRA-F is a chainsaw felling grab for swinging installation, engineered to fell and service trees efficiently from excavators or truck cranes. Its structural components are manufactured from Strenx 700 steel and the unit operates without electrical components, simplifying maintenance.
Key benefits- Designed to fell and maintain trees and to cut and move logs of small or large diameter.
- Reduces tree cutting time by up to 80%, increasing jobsite productivity.
- Robust structure in Strenx 700 steel with no electrical components for greater reliability in harsh conditions.
- No traditional maintenance required on the chainsaw basket, lowering operating costs.
SafetyPatented spring-loaded safety system prevents the bar from getting stuck during cutting, improving operator safety and reducing downtime.
