Rail breakers Cayman RB Series

The Cayman RB rail breaker is successfully and profitably used in the volume reduction industrial sector and in the subsequent recycling of railroad and tram rails, making expensive manual oxyfuel cutting systems, traditionally used for these pieces, completely useless and obsolete. Among the innovative design and numerous cutting-edge technical qualities of all Zato’s machines, the Cayman RB rail breaker is also itself the result of our long experience in the design and construction of recycling equipment.
