APPI Hydraulic Yarding Systems
High Profit Production
APPI has been supplying hydraulic yarding systems for more than 30 years with hundreds of systems in operation in the field.
Our hydraulic yarding systems can be installed either log loaders or excavators without detracting from the original use of the machine as they have the ability to switch from loading / excavating to yarding in minutes. Operators can easily set up for logging using gravity carriage (uphill settings), highlead (downhill or flat settings) logging or a combination of both.
As the equipment will be capable of multiple use you’ll have lower operating costs, diminished capital investment and increased year-round flexibility.
