the 30-ton capacity of this hydraulic cylinder jack is more than sufficient for most heavy-duty tasks. The cylinder is made of high-strength steel, ensuring durability and long-lasting use. The single acting design is perfect for applications where the weight of the load provides the necessary force for lowering, while the hydraulic system is used to lift the load.The 4-inch stroke is another great feature of this cylinder jack. It provides ample lifting range, and the smooth operation of the hydraulic system ensures precise control during the lifting process. This is especially important in shipbuilding applications, where precise alignment of large components is crucial.The Porta Power Ram is also very easy to use. The hydraulic pump is built into the cylinder, making it a self-contained unit that requires no external power source. The pump handle is ergonomically designed, making it comfortable to use even during extended lifting operations. The cylinder also features a pressure relief valve, which helps prevent overloading and ensures safe operation.In terms of portability, the Porta Power Ram is excellent. It weighs only 58 pounds, making it easy to move around the job site. The cylinder also features a carrying handle, which makes it easy to transport.

I have a shipping container that shifted with the frost and was binding. I have a small shipping container jack adapter that can only receive a smaller bottle jack sized lifting device. Enter this small form factor of a jack. I was able to use it with my air operated power pack and lift the container into place in seconds. A couple of shims later, and I was back in business.

This thing is super heavy and requires a special pump to operate it.
