Advanced Trickline Tensioning Systems
Double Ratchet Tricklines
The less expensive way to enter into the world of serious tricklining is by the use of double ratchet kits. Double ratchet slackline kits usually feature up to 100 ft (30 m) of 2’’ polyester webbing, 2 ratchets with attachment slings, 2 shackles, 2 spansets and backup ropes/webbing. Some include soft release systems to decrease the static load in the slackline before releasing tension in the ratchet. If your kit does not come with a soft release system, we recommend getting or creating a soft release because ratchets released under high tension can release violently. We will be covering soft release systems in the “Alternative Tensioning Techniques” article.
Pulley System Tricklines
Pulley system tricklines are more expensive to assemble yet can deliver just as much or more power than ratchet tricklines. This is due to the webbing combinations available such as threaded tubular webbing and various styles of polyester. Additionally, the pulley system can be used for tensioning longline systems as well. Because of the high forces involved in tricklining it is necessary to get very strong pulleys or use many pulleys to distribute the load over multiple pieces of hardware.
Hardcore trickliners sometimes use 9:1 block and tackle pulley systems. This isn’t necessarily to gain additional mechanical advantage but to make sure the hardware is being subjected to the appropriate WLL it was designed for. The larger throw of the pulleys makes it possible to tension long pieces of 1 ¼ ‘’ threaded tubular webbing. The 1 ¼” webbing requires specific weblocks made for 1 ¼” wide webbing. They follow the same principle as those used for longlining but are slightly wider. There are also some 2’’ wide weblocks available.
