GRA-R series
\ Description
GRA-R log grabs stand out for strength and resilience. They are built with a 4-finger configuration, without plates at the tip of the arms. This allows for agile and unrestricted movement in any condition. Sturdy and reliable, they can be used both in the woods and on yard, with a high gripping strength and long-lasting reliability.
Two connecting rods and a centrally placed hydraulic cylinder (all models except GRA-R 22 which has a single rod) ensure a perfectly uniform push. The specially-designed conical pins allow a quick and easy balancing of the plays that naturally occur when working with this kind of equipment.
\ Uses
GRA-R log grabs can be installed on cranes from 8 to 20 ton/m and excavators from 5 to 15ton of weight.
