Suspended loads entangled with climber
Rescues where a loaded rigging line has trapped or crushed the climber or their climbing systems may be among the most challenging tree rescues to undertake . The problems of height access and extrication remain , with the addition of ropes under tension , compromised climbing systems , compromised anchor points and suspended loads . Ropes running under tension may have
caused damage to climber ’ s lines or rope burn injuries to the climber .
The first priority if it is safe to do so should be to attempt to lower the load to the ground and unload the system . If it is not possible to safely lower the load , the priority becomes securing the load so that the rescue can be safely conducted .
Where the friction management device has tie-off posts or cleats , the loaded rope can be snubbed off on these .
First take multiple turns around the barrel or drum of the device . Then snub off the rope by dropping a series of alternating half-hitches over the two opposing posts . Finally , tie off the rope by securing the tail to a suitable anchor .
Where the friction management device has no tie-off posts ( e . g . the rigging winch pictured ) the rope must be tied off around a separate anchor or around the base of the same tree .
First take multiple turns around the barrel or drum of the device . This adds friction , so that if the suspended load becomes dislodged and falls onto the lowering rope during the rescue , the knot will not become bound up and the load will still be lowerable .
Where possible , the tree company ground crew can be asked to secure the rope onto these devices , as they will be familiar with the device and the correct process to use .
