As a minimum, a basic anchor system consists of two ropes, each with its own anchor connection.
Where a suitable structure is present, ropes can be simply rigged to two similar anchor slings or strops
placed next to each other.
Where ropes are to be rigged from two separate structural elements or bolt anchors, the rigging of a Y-hang
offers three advantages: precise positioning of ropes, sharing of loads on the anchors, and
reduced impact loads in the event of anchor failure.
