In order to get a
glider into the air, you either need a powered plane to tow you, or
set up a winch. A tow plane is very expensive, so I decided to have a
winch built.
Jonathan Tayamora, a
paraglider pilot here in the
Philippines,
happens to be a gifted engineer.
Jonathan’s winch appears to be a masterpiece of glider winches. It is
powerful, yet mechanically very simple. Acceleration is smooth, controls
are easy to handle. The shifting mechanism for both drums is his
invention. He converted a truck differential.
We have installed a 1000m steel
cable (0,42cm), locally sourced.
The winch is installed on
an Isuzu Elf truck. The engine comes from an Isuzu 320hp turbocharged
diesel truck. We could buy a second hand Voith fluid turbo coupling to
dampen the acceleration.
You can see the winch operating in this
