Heli-Tractor is used by the World Wildlife Foundation (WWF) to air lift Rhinos from the location where they are tranquilized to the support vehicles which are used to load them. This task has to be done as quickly as possible as the tranquiliser could wear off and they don’t want to administer too much as it’s a very strong drug.
Flying has to be done with precision and the animal must be cared for whilst under the Huey to ensure its life is not endangered.
The Huey has to be very strong to handle these loads of 1250 kgs upwards in the African heat and altitude.
