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.
