Rigging Blocks & Pulleys
  • DMM Revolver Rig and Rig Twin

    (Rig Twin not yet available)

    Revolver evolves.
    The Revolver Rigs bring industrial strength and performance to our innovative pulley wheel/connector combo to give an incredibly versatile connector that can be used in any running rope system to increase efficiency.
    The Revolver Rig comes into its own when flexibility and efficiency are paramount, it excels in improvised rescues, compact mechanical advantage systems and reducing friction in rigging featuring ropes.
    Both Revolver Rigs feature a becket with a 90° twist allowing connection of textiles or connectors while minimising interrope contact for greater efficiency. Integrating a highly efficient pulley wheel into a connector that resists cross-loading creates a secure, adaptable device that increases options when improvising or creating complex rigging set ups, while reducing the number of devices the user needs to carry to construct such configurations.
    The twin sheave version allows compact mechanical advantage systems to be created with the minimum of equipment.

     

    Features:

    • Large sheave tread diameter for large rope bend radius
    • High efficiency roller bearings
    • Uniquely profiled spine to aid correct orientation
    • Full strength becket accepts most carabiners or direct
    • textile connection
    • Removable captive bar
    • DMM iD optional
    • Keylock nose for snag free operation

  • DMM IMPACT BLOCK - L

    As you would expect from a product called an 'Impact Block' it's only purpose in life, apart from looking good, is to help absorb huge impacts created by the harsh dynamics of heavy arborist work. When rigged as part of an impact system, our block offers maximum security and strength with minimum fuss and weight. Every component, every curve, every surface has been analysed, designed and engineered to deliver the best performance in terms of dynamics, resistance and alignment. The combination of high quality materials and our hot forging process gives a rope friendly, durable and robust block that can withstand the abuses of advanced tree felling and rigging work. Our blocks have gone through a rigorous dynamic and static testing regime, and have been mis-treated and abused as much as possible; the end result is a highly functional product with an impressive strength to weight ratio. If ever there was a component in a safety chain destined to take abuse, this is it...

    With a massive Minimum Breaking Strength (MBS) of 300kN and a Working Load Limit (WLL) of 60kN, the Large Impact Block sets new standards in handling massive drops.

    The Small Impact Block is small by name, small by nature (relatively speaking) yet still big in strength. With a massive Minimum Breaking Strength (MBS) of 200kN and a Working Load Limit (WLL) of 40kN, it is incredibly strong, yet can almost be carried around on a harness.

  • 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
