DMM Rigger Pulley An evolution of DMM’s original Triple Attachment Pulley, redesigned for increased strength, efficiency and longevity. The DMM Rigger Pulley builds on over a decade of proven design, combining a hot-forged swing-cheek pulley with an integrated three-hole rigging plate. This unique configuration allows highly creative rigging setups while enabling direct connection to textile components, reducing both weight and system complexity. The Rigger features a newly developed axle construction produced using highly accurate CNC operations. This results in a significantly stronger axle-to-side-plate interface, greatly improving durability and long-term performance in demanding rigging applications. Key Features & Benefits Integrated three-hole rigging plate: Enables versatile configurations and direct textile connections. Ultra-high strength side plates: Bolstered connection areas deliver very high configured strengths. 40 kN maximum breaking strength: Achieved through new side plate geometry and axle design. High-efficiency roller bearings: Ensures smooth operation under load. Hollow axle construction: Reduces overall weight without compromising strength. Optimised fairleads and tuned angles: Improve prusik-minding efficiency. Multi-function design: Can be used as a rigging plate with or without the sheave installed. Axle & Plate Design Explained The Rigger Pulley uses the same proven sheave as the previous DMM Triple Attachment Pulley, combined with a completely redesigned axle and side plate system. CNC-machined accuracy produces a robust axle and nut interface, while increased rope-bearing cross-sections around the attachment holes improve performance when connecting textile components directly. Optional Locking Hardware An optional M5 nut and bolt can be used to lock the side plates together. This locking hardware is non-structural and is available separately. Recommended hardware specification: M5 × 16 mm countersunk screw – A2 stainless steel M5 Nyloc nut – A2 stainless steel Technical Specifications Specification Detail Product Name DMM Rigger Pulley Maximum Breaking Strength 40 kN Working Load Limit 8 kN Dimensions 68 × 94 mm Weight 176 g Compatible Rope Diameter 7 – 14 mm Sheave Diameter 42 mm Bearing Type High-efficiency roller bearings Certification EN 12278:2007 Why Choose the DMM Rigger Pulley?
