What is constant tension winch?
Constant tension winch systems are used for difficult operations in harsh marine environments. The system creates a constant line-pull between the load and the lifting device. If the actual value differs from the pre-set value, the winch will pay in or pay out wire rope to maintain the pre-set value.
