Carriage HY-2

Another highlight in our range is the extremely compact and remote-controlled carriage HY-2. The patented system is fabricated from high strength steel, four times stronger than conventional steel. Thanks to the remote control, the operator in the forest can stop and secure the carriage at the exact right location. The mainline clamp allows the carriage to be released while the load is raised, permitting movement to a new location and re-clamping to the cable. This facilitates the sideways pulling of the load and protects the remaining timber growth from damage. As soon as the hook is drawn tight into the carriage, the skyline grip automatically releases, allowing travel of the unit. As soon as the hook is drawn into the carriage, the hook is secured against rotation, preventing damage to the mainline. The carriage travels over the normal Wyssen support saddles. The cable safety brake activates an emergency stop if the mainline is ruptured. In the event that severe swinging motion causes the grip to clamp outside the skyline, the clamping process would be repeated until the carriage stops. An unintentional release by slackening of the mainline while passing a tower is prevented by the control system.
