Rigger Pulley

The DMM Rigger Pulley is an extremely strong and versatile pulley with a built-in rigging plate. This pulley offers both high performance and flexibility for all rigging needs.

The DMM Rigger Pulley is a further development of the earlier Triple Attachment Pulley introduced 10 years ago. The hot-forged swing-cheek pulley with a built-in three-hole rigging plate allows creative configurations and direct connection to textile components to save weight and reduce complexity. The Rigger Pulleys have a new axle construction made with high-precision CNC machining, providing a stronger interface between axle and side plate for increased durability.
Reinforced connection areas provide high configured strengths. The newly developed side plates in combination with the axle construction result in a significantly increased minimum breaking strength (MBS) of 40 kN. The side plates have improved fairleads and optimised angles for more efficient prusik management.

Features:

• Extremely strong pulley side plates
• High-efficiency roller bearings
• Hollow axle for reduced weight
• Increased rope-bearing cross-section for textile connections to the attachment holes
• Same sheave as the earlier Triple Attachment Pulley
• New axle design for increased robustness at the interface between axle/nut and side plate
• Optional M5 nut and bolt for locking the side plates, can be fitted from either side
• Optional DMM ID marking
• Can be used as a rigging plate with or without the sheave
