Rigging Blocks

Rigging Blocks
  • At approximately half the size of the standard small rigging pulley and weighing in at only 490g (1lb), the new Compact Rigging Pulley offers a highly impressive strength to weight ratio with an 85kN (19000lbf) MBS and a WLL of 17kN (3800lbf).

    The Pulley plates are made from hot forged Aluminium and it is this manufacturing process which allows such a compact pulley to boast such great strength and dynamic load bearing capacity.

    Working Line (Grey Sheave):
    13mm (1/2") - 38kN (8500lbf)

    Topping Strop (Red Sheave):
    16mm (5/8") - 74kN (16650lbf)

    The Compact Rigging Pulley is fitted with a spring-lock closure mechanism.

  • 100kN was 5007S (Able to take 20mm on topping pulley)To get the most out of your favourite ropes, or to create a crotch where none is available, simply tie the sling around the tree, below the area to be cut, with the pulley on the falling side. By threading your lowering line through the pulley at the new pivot point, instead of the rough crotch of a tree, heat and friction are reduced to nearly zero. Bull ropes will last longer, and, combined with a 'Port-A-Wrap', will provide you with greater control of heavy wood, eliminating the destruction of expensive or sensitive landscapes. This system provides an instant, frictionless pulley for your ropes to run or a leverage vantage point above heavy limbs targeted for removal.- side cheeks are aluminium with an epoxy polyester coating- stainless steel sheave and bushing pins- spring loaded upper pin with a captive bushingSimply push and twist the upper pin and the cheek plates will open . And best of all, the bushing and pin cannot fall out of the block.Tested to 10.2 tonne, safe working load 1.5 tonne.

  • ISC Rigging Blocks have colour coded Side plates and Pulley Wheels, helping the user to easily identify the correct Block for the task. We have introduced a new fixed bollard dimension, which allows the user to fall in-line with rigging standard practice,whereby the Anchor/Topping Strop should be twice the Strength of the Working Line.

    Safe working load 20kN. Min. breaking strain 100kN. 16mm rope capacity. all models are able to take 20mm on topping pulley
