DMM 20mm Large Impact Rigging Pulley Block

DMM 20mm Large Impact Rigging Pulley Block

The DMM 20mm Large Impact Rigging Pulley Block is engineered for professional rigging environments where loads may be dropped onto the system with significant impact forces. Designed for arborist, rescue, and industrial applications, it combines advanced manufacturing techniques with high quality materials to deliver exceptional durability, strength, and rope-friendly handling. Despite its substantial capacity, the block is carefully balanced to provide high performance without unnecessary bulk, making it a dependable choice for demanding daily use.

Built for extreme impact and dynamic rigging

This large impact block is purpose-built for scenarios involving high dynamic forces, including negative rigging, heavy lowering, and complex redirects. With a minimum breaking strength of 300 kN and a working load limit of 60 kN, it offers a substantial safety margin for critical operations. The block is designed to accommodate rigging lines up to 20 mm in diameter, supporting use with larger ropes commonly required for heavy timber handling and industrial lifting tasks.

Efficient rope handling with clear load identification

The sheave and side plate geometry are designed to maintain smooth rope travel under load, helping reduce friction and minimise rope wear during operation. Sheave colouring follows the EU working load limit protocol, supporting quick visual identification on site and helping operators maintain correct system selection. Measuring 230 x 125 x 90 mm and weighing 3.47 kg, the block balances robust construction with practical handling during installation and repositioning.

Certified performance for professional environments

The DMM 20mm Large Impact Rigging Pulley Block conforms to EN 12278:2007 and NFPA 1983 (2012 Edition) Class G, supporting use in regulated professional settings. Extensive dynamic, torsion, and static testing has validated its long-term reliability in tough working conditions. This combination of certification, strength, and proven durability makes it suitable for operators who require consistent performance when managing high loads and impact forces.
