ANCHOR PLATE for pulley deviation

Managing double acrobatic safety lines with a double pulley poses numerous problems in terms of friction and poor pulley placement.

Using two single pulleys placed side by side is always preferable to using a double pulley.

However, positioning these pulleys in space is not always straightforward.

This plate has therefore been specially developed to separate the two single pulleys and the two ropes in order to avoid friction and shocks.

Principle and advantages

The two single pulleys are spaced apart to allow them a wide range of movement, angle, and rotation.

They can therefore act independently to automatically align themselves with the forces in the ropes and follow the acrobat's movements, even outside the plane of the lanyards (in front and behind).

They can be placed at different heights so that the rope directed towards the acrobat naturally passes under the rope that runs horizontally towards the third pulley. This prevents friction between the ropes, even when used in a “swinging” manner.

The 17 mm mounting holes (6 mm thick) have been optimized to directly accommodate the stainless steel shackles of main sailling blocks. Example: WICHARD self-locking bow shackles mounted on RONSTAN CORE 60 or 75 blocks.
