Ram Blocks – The “big boy” range grows

Author: Allen Brothers   Date Posted:17 April 2023 

Allen continue to evolve their range, should you have a project like this please get in touch as we work closely with the team at Allen here in our region.

Two years ago we introduced the aptly nicknamed “big boy” block to the worldSo, in 2023 it should come as no surprise that the “big boy” has now grown into a range of products. The more correctly named, ram block range, is now available in 150, 85 & 50mm sheave sizes.

You might be shocked to see those sheave diameters, but yes you did read correctly. And you shouldn’t be surprised. Here at Allen, we are much more than just small boat hardware specialists. We are engineering experts and we produce a vast range of equipment for many different business sectors.

However, we might expect you to be a little curious how a family-run business which specialises in performance sailing hardware for Olympic-sized boats makes the jump to blocks which weigh around 5 kilos, and have breaking loads of 28 tonnes.

Well, our friends at Ocean Marine Systems (OMS) approached us to help solve some rope management problems they faced when developing custom hydraulic rams for a project of theirs. Our design team jumped at the opportunity and developed the “big boy”.

Fast forward two years and OMS have been so happy with the quality and performance of the “big boy” that they asked us to develop a further two sizes of ram blocks. First was the 50mm sheave diameter single block. Then, an 85mm version was needed in both a standard single and single with becket.
