ASI Hydraulics’ series of 40HP Portable Power Units are great units used in mobile machining; specifically when you need variable speed to operate your clam shell and tooling at the same time. This unit has a unique close-coupled pump to motor combination to save the maximum amount of space and reducing the footprint for more of a portable power unit. The roll cage that is built around our units is extremely tough and does the job of protecting the vital components while in transportation and in use.
