Belaying

Provides a fall protection safety to the “on-rope” rescuer that creates friction on a secondary or “belay” rope thus stopping or reducing the fall..

Is considered 2nd point of attachment.Is required during lower or raising

operations.

Belaying

Types of Belays: Direct

Attaching the rope friction device directly onto the anchor point.

This is done by reeving the running rope through a fiction device via a sling, directly to the anchor point.

Forces generated by a falling climber impact directly onto the anchor points.

Belaying

Types of Belays: Indirect

Belayer attaches to the anchor, and places the rope through a belay device attached to his harness.

Any forces generated by falling climbers are transmitted via the belayer to the anchor.

Allows a lot of the shock to be dissipated before coming onto the anchor points.

Belayer often gets pulled around, and it is more difficult for him to escape from the system if needed.

Belaying

Types of Belays:Body Belay

Used when climber is unlikely to take a serious fall.

Rope passes around the back of the climber.

Often a carabiner clipped on to the anchor or preferably the front of the harness prevents the belay rope from being whipped to far up (or down) in a fall.

Types of Belays:True Belay:

Fall Arrest Belay Team

Belaying

Types of Belays:Pseudo Belay:

Fall Arrest attached to rappeller harness via prussik or cam.

Fall arrest can be attached to mainline or to a secondary static rope.(belay line)

Belaying

Types of Belays:Bottom Belay:

Fall Arrest attached to bealyer on ground using body belaying techniques.
