The indoor system means training is not weather dependent and more than three people can be trained in one session.
Those who require training include the volunteer helicopter crewmen, St John paramedics, search and rescue members and rescue swimmers.
The winch system is set up just like the real thing with those in training required to follow all the same procedures, including the use of headsets.
The system would have cost between $10,000 and $12,000 but all parts and labour were donated.
The crew has used its winch quite recently, picking up lost hunters and an injured mountain biker among them.
