Carriage Slackpuller

The motorised slackpuller is designed for long-distance cableways and mobile cableways.

Set up and function

The latest development is the extremely compact, remote controlled Wyssen slack-pulling carriage. The chassis of the carriage is made of high-tensile steel that is four times stronger than conventional steel. Thanks to the remote control, the operator in the forest can stop and secure the carriage at the exactly right location. The spooling procedure starts automatically (needs no radio-controlled command). The mainline clamp allows the slackpuller to be released while the load is raised or lowered, 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. During travel of the unit, the hook is secured against rotation, preventing damage to the mainline. The slackpuller is also available with a pendulum (recommended for long-distance cableways). The pendulum can be retrofitted at any time. The carriage travels over the popular heavy-duty Wyssen support saddle. The mechanical mainline safety feature activates an emergency stop if the mainline is ruptured.
