Abstract
A skyline cable logging system in which a skyline carriage runs on a skyline cable (106) between a yarding hauler (101) and a remote mobile tailhold (113) has the remotely controllable mobile tailhold powered and with winch tails which are connected to multiple anchor points (110). With the skyline tensioned so that the mobile tailhold is aerial the winch tails can be varied to traverse the skyline end between anchor points (110). The anchor points (110) can be relocated one at a time to allow the skyline to traverse a large area.
Claims16
A mobile tailhold for a skyline logging system, the mobile tailhold having at least two mobile tailhold powered winchable cable tails, the cable tails being winchable by at least one mobile tailhold mounted winch, the cable tails each being attachable to an anchoring point such that the mobile tailhold can be positioned relative to the anchor points by winching the cable tails with the at least one mobile tailhold mounted winch.
A skyline logging system having at least a skyline cable supported between a hauler and an aerial mobile tailhold, the mobile tailhold being anchorable to at least two separate tail anchor points by cable tails, the mobile tailhold having at least one mobile tailhold powered winch adapted to separately pay out or pull in the cable tails, the mobile tailhold being movable aerially from adjacent one anchor point to adjacent another anchor point by paying out one cable tail and pulling in another cable tail.
A lateral deflection jack for a cable logging system, the jack having a flame capable of being attached to an anchor point, at least one pivoted cable receiving shoe pivoted from the frame, the pivotable cable receiving shoe having spaced upper and lower plates, the upper plate having a substantially flat upper surface, the space between the upper and lower plates defining a cable receiving recess, the upper plate being over-rideable by at least one supporting sheave of a carriage, the carriage running on a cable received in the space between the upper and lower plates.
