Climbing Pulleys
Efficient hauling starts with premium Climbing Pulleys
At The Outdoor Warehouse, we carry a trusted selection of climbing pulleys for hauling, rescue, big wall climbing, and rope access. From compact progress capture pulleys to high-efficiency rescue pulleys, the right choice can make your system stronger, smoother, and safer.
Also known as haul pulleys, rescue pulleys, rope access pulleys, arborist pulleys, and rigging pulleys, these devices reduce friction, improve hauling efficiency, and add reliability to your climbing system.
Why the Right Pulley Matters
- Efficiency: High-quality sealed bearings reduce friction for smooth hauling.
- Strength: Built to handle rescue, hauling, and technical rigging loads.
- Versatility: Options for climbers, arborists, rope access technicians, and rescuers.
- Durability: Brands like Rock Exotica, SMC, and Kong design pulleys for heavy use in demanding environments.
Understanding Pulley Ratings
Every climbing pulley is stamped with strength ratings and certifications that help determine the right use case. Here’s what to know before you climb, haul, or rig:
- MBS (Minimum Breaking Strength): The maximum load a pulley can withstand before failure, expressed in kilonewtons (kN). Always stay well below this value during real-world use.
- Working Load Limit (WLL): The recommended safe working load, often set at 1/10 of the MBS. This is the number you should trust for everyday climbing and hauling.
- Rope Compatibility: Pulleys are designed for specific rope diameters (e.g., 8–13mm). Using the wrong diameter reduces efficiency and safety.
- Efficiency Rating: High-quality pulleys (like those from Rock Exotica) list efficiency percentages (e.g., 90%+), showing how much they reduce friction compared to rope-on-rope contact.
- NFPA “G” Rating: Pulleys with this rating meet National Fire Protection Association General Use standards. They’re tested to higher loads (typically 36 kN+) and are designed for rescue operations, fire service, and technical rigging. In contrast, NFPA “T” (Technical Use) pulleys are lighter and rated for smaller loads.
- Rope Access & Arborist Use: Beyond climbing, pulleys play a vital role in rope access systems (industrial work-at-height, window cleaning, tower climbing) and arborist rigging (tree care, limb lowering). These pulleys often feature large sheaves, swinging side plates, and efficiency ratings optimized for repetitive hauling.
Tip: Always look for UIAA, CE, or NFPA certifications etched on the pulley body — it’s your guarantee of quality and safety.
Climbing Pulleys at a Glance
| Type | Best For | Key Features |
|---|---|---|
| Standard Pulley | Basic hauling | Simple design, lightweight, compact |
| Progress Capture Pulley | Hauling systems | Integrated cam holds progress, rescue use |
| High-Efficiency Pulley | Big wall hauling, rescue | Sealed bearings, >90% efficiency |
| NFPA “G” Rated Pulley | Rescue & rope access | 36 kN+, certified for general use loads |
Common Mistakes to Avoid
- Using a pulley not rated for your rope diameter.
- Confusing MBS with WLL and overloading gear.
- Skipping sealed bearings when efficiency matters for hauling big loads.
- Using non-NFPA pulleys for rescue scenarios where certification is required.
Climbing Pulley Checklist
- ✔ Verify rope compatibility (diameter range).
- ✔ Check NFPA/CE/UIAA certifications before use.
- ✔ Choose sealed bearings for heavy hauling or rescue.
- ✔ Retire pulleys with worn sheaves or damaged side plates.
Pro Tip
Pair your pulley with Climbing Connectors or Carabiners for secure attachment. For arborist work, always match pulleys with ropes rated for rigging, not dynamic climbing ropes.
