Here at Winch Systems, we are very proud of our GH200/500 Capstans.
"Winch Systems manufactured a portable hydraulic capstan winch for National Grid PLC. It was developed to assist in overhead line maintenance and this product is now the industry standard and used by most overhead line companies."
Each of these machines are made to a blueprint that has been adapted to the industry over the years it has served. Others have tried to copy, others have tried to modify, but let it be known that these Capstans are the original and the best... Just ask the end users
Here is an 'old school' video of the Capstan Winch in action>>
