PART 4: Gin Pole | TWIN BUNDLE | Horizontal Rigging

  The Gin Pole: The floating gin pole (mono-pod) is a useful alterative for a high directional especially when backpacking long distances. With proper guying in place, the gin pole works quite well as a high directional for a highline system. Sterling Rope is the Official Rope of Rescue Response Gear’s The Rigging Lab. The […]

PART 5: Termination Side | TWIN BUNDLE | Horizontal Rigging

The Termination Side: This video shows one of many methods to eliminate a knot in the trackline of a highline system. Depicted here is single prusik bypasses; one per each leg of the twin bundled system. The single prusik is a load cell in its own right…if the trackline is receiving too much tension they

PART 1: Tensioning Side | QUAD BUNDLE | Horizontal Rigging

Tensioning Side Tensioning a quad-bundle trackline is particularly rigging intensive and requires practice and patience. As with all trackline tensioning systems of highline construction, we must be diligent of not over tensioning. In addition, with all multi-bundles, equal tension is imperative. During this short video you will see how to rig a 3:1 on each

PART 3: Carriage System | QUAD BUNDLE | Horizontal Rigging

Carriage System The carriage system for a quad bundle highline is very similar to the single trackline. The composite rigidity of 4 ropes is twice as much as that of 2…we can now keep our deflection at 2.5% of the overall length of span. This is a good system for heavy loads and/or extremely shallow

PART 5: Termination Side | QUAD BUNDLE | Horizontal Rigging

The Termination Side This video depicts the termination of a quad-bundle trackline. Once again we are using prusik bypasses on each leg to eliminate the knot from the system. If these bypasses were to receive excessive tension, slipping would start to occur, thus easing the transfer of the load onto the termination knot. Highline operations

Confined Space Rig | Knots & Pulleys in Rope Rigging Systems Vol. 1 Segment 8

The “Confined Space Rig” is a compound 6:1 that when configured in the manner shown in this sequence, it works extremely well for straight vertical confined space drops. This sequence will take you through the steps. The way we address knots, MAs (Mechanical Advantages), and Anchors in these videos are more general and with a

Pulley Systems Rules | Knots & Pulleys in Rope Rigging Systems Vol. 1 Segment 6

In this sequence we address the 5 basic rules of constructing a simple mechanical advantage with pulleys and pulley systems. This information has been handed down over centuries through the mariners industry and they still hold true for today in a very useful understanding. The first rule is… if the rope is tied off at

Microcosm of Knots | Knots & Pulleys in Rope Rigging Systems Vol. 1 Segment 5

Knots are a microcosm of rigging; this is to reinforce the fact that even the smallest aspect of rigging — the knot — is of huge importance. All the physical attributes in large rigging systems are also present in a single knot! The way we address knots, MAs (Mechanical Advantages), and Anchors in these videos
