2. Z-drag - Wikipedia

   en.wikipedia.org/wiki/Z-drag

   It is also considered a useful tool in many types of rope rescue, such as crevasse rescue, because of its simplicity, and is commonly used for lifting systems that don't require much more mechanical advantage. [5] It also serves as a method for tightening the rope in a Tyrolean traverse, where the other end is fixed to a stable object.

3. Hoist (device) - Wikipedia

   en.wikipedia.org/wiki/Hoist_(device)

   Hoist atop an elevator. A hoist is a device used for lifting or lowering a load by means of a drum or lift-wheel around which rope or chain wraps. It may be manually operated, electrically or pneumatically driven and may use chain, fiber or wire rope as its lifting medium.

4. Rigging (material handling) - Wikipedia

   en.wikipedia.org/wiki/Rigging_(material_handling)

   Rigging comes from rig, to set up or prepare. Rigging is the equipment such as wire rope, turnbuckles, clevis, jacks used with cranes and other lifting equipment [1] in material handling and structure relocation. Rigging systems commonly include shackles, master links and slings, and lifting bags in underwater lifting.

5. Radium release hitch - Wikipedia

   en.wikipedia.org/wiki/Radium_Release_Hitch

   A radium release hitch is a load-releasing hitch using 3:1 mechanical advantage which is used in a two-rope technical rescue system. [1] The Radium Release Hitch allows a load to be transferred from one rope to another and is commonly rigged into the belay line prior to the operation of a two-rope technical rescue system.

6. Precast concrete lifting anchor system - Wikipedia

   en.wikipedia.org/wiki/Precast_concrete_lifting...

   The rigging arrangements can influence the applied anchor load, where statically indeterminate systems are not necessarily a design consideration, but can be used in practice. The determination of the loads through the rigging system must be a consideration whilst calculating the load resistant model, refer to the examples shown in Figure 3.

7. Single-rope technique - Wikipedia

   en.wikipedia.org/wiki/Single-rope_technique

   For safe single-rope technique, especially on drops with complex rigging with intermediate belays, it is essential that the abseiling device can be removed from the rope without being unclipped from the harness. This is a problem with the simplest device, the single piece figure eight. These also twist the rope, which is a problem if there is a ...
