DMM Impact Block - Small
Description
Description
DMM Impact Block - Small is a compact yet extremely rugged pulley, specially developed for arborists and tree climbers exposed to high shock loads during rigging and tree felling. Despite its small size, it offers a minimum breaking strength (MBS) of 200 kN and a working load limit (WLL) of 40 kN, making it ideal for demanding applications in the tree top.
The DMM Impact Block Small combines high-quality materials and advanced manufacturing processes to deliver a rope-friendly, durable and reliable product. It has undergone rigorous dynamic and static testing, resulting in an impressive strength-to-weight ratio. The pulley is made in Wales from hot-forged aluminium alloy 6082-T6 for optimal strength-to-weight, polished, heat-treated and anodised for corrosion protection according to EN-12373-1:2001 Class I0EI.
Features
- Rounded edges on the cheek plates minimise rope abrasion even with "unfair" loading of the rope.
- Fairlead flare design maintains high working efficiency.
- Thrust surfaces increase tolerance to external loading on the axle and anchor pin.
- Lightweight attachment strap makes handling, transport up to the climber, storage in the tree and workshop easier.
- Direct connection to a line ensures compatibility with adjacent components; max sling diameter 22 mm.
- Highly efficient oilite bushings reduce friction.
- Individual serial marking for traceability.
- Colour coding follows the EU WLL protocol.

- Captive top plate with knurled locking screw.
- Advanced rigging options via the spindle.
- Eye for hanging the block on the saddle with rigging intact.
