Rope too short for back-pulling

A skidder operator was fatally injured while back-pulling trees.

Circumstances

The skidder was being used to back-pull cut-up trees. A rope was attached to one tree and was fully extended. The skidder was positioned directly in line with the intended direction of fall. As the operator got off the skidder, the tree being back-pulled, as well as two other trees that had been scarfed and cut up, were released from the tow rope and fell onto him.

Investigation

The skidder was too close to the trees being back-pulled because the rope was too short. The operator should not have climbed off the skidder until he had completed the operation. Although he had 10 years’ experience in bush work, he had no training or experience in operating a skidder. The operator fractured his pelvis and later died from his injuries.

  • the machine shall be of sufficient size to handle all aspects of the operation
  • the faller and the machine operator shall have an effective means of communication
  • when using rope pulling, the rope shall be secured as high as practicable on the tree
  • the machine shall not be in the direct line of the intended direction of fall.
