Today a customer had a BUKH 24 DV engine weighing 223kg. He can either use RAB 2 or RAB 3 mounts – They will need 4 mounts with the RAB 2 taking maximum 105kg in weight each or RAB 3 taking maximum 70kg each.
His decision could be based on the static deflection:
RAB 2 = 1.75mm
RAB 3 = 2.75mm
Please see our page for RAB mounts to calculate your requirements.
