Remote controlled slack pulling log skidding carriage |
摘要 |
A remote controlled slack pulling log skidding carriage is provided for feeding a slack drag line toward a log to be skidded. A drive sheave rotatably mounted in the carriage is operated by a hydraulic motor. The fluid to operate the hydraulic motor is stored in one or more accumulators, and a radio controlled valve starts and stops the flow of fluid to the motor. A mechanically operated hydraulic pump also is provided to recharge the accumulators during a skidding operation.
