The use of the double drum winch is not familiar to many people and hence this Booklet has been produced in the hope that it will be of assistance to those using the double drum winch for the first time. There are many points of organisation and technique that play a large part in achieving a high output using a double drum winch. This Booklet records those that have been found useful in this country to date, however, even though several pairs of operators have been employed, experience has been limited to a few machines and cannot be comprehensive.
