GRA-M series
\ Description
GRA-M is the standard series of log grabs, suitable for work on cranes and excavators. 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 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-M log grabs can be installed on cranes from 10 to 25 ton/m and excavators from 6 to 18ton of weight.
