Pulley, rotating device in continuous technological evolution
A pulley is a simple rotating device, used to move loads since ancient times. The lifting pulleys, greatly amplifying man's strength, allowed to move columns, drag blocks, pull ships, etc.
The maximum mechanical advantage in the use of a pulley would be in the theoretical condition of zero friction. So the lower the friction generated, the better the quality of the pulley.
The evolution of materials and production technologies have transformed the pulley into highly efficient and performing devices. In this section of our shop you'll find all the best pulleys with bearings to build a rope pulley system for Longlining or Highlining.
Pulleys There are 16 products.
What is the difference between a mobile pulley and a fixed pulley?
When pulling on a rope and your pulley stays in its initial place, this would describe a fixed pulley. If it moves while pullimg you have a mobile tensioning pulley system. A mobile pulley is offering usually more power and strength to your pulley system than a fixed one.
In the world of slacklining, you should always work with mobile pulleys and brakes, as the usually required tension is quite high and a pulley system must stay under control under during each phase: tensioning, usage, release of tension.
The small pulleys as multipliers
In order to rig a slackline longer than 20m, a single person's strength is never enough, due to this we need to multiply it.
Multipliers are simply single pulleys connected to the last (exiting) rope of the pulley system to increase the efficiency of tension by multiplying the theoretical work with a ratio of 3:1 (multipling 3 times the applied force), 9:1 (9 times the applied force), up to a maximum of 27:1.
Double, triple, quadruple pulley and self-locking pulleys
Pulleys can have multiple number of wheels or rotating bearings to obtain a more advanced and more efficient system.
In our shop you'll find a collection of Spider Slacklines pulleys: The ROLLEX carabiner pulley, a MINI DOUBLE pulley, a SLACKIMOUFLE QUAD pulley etc.. Furthermore, the best CAMP and PETZL pulleys, and the opening pulleys from CLIMBING TECNOLOGY such as the ORBITER T double pulley or the ORBITER H and ORBITER L triple pulley.
