A pulley is a device that guides a rope or strap to change the direction of pull, reduce effort, or lift a load. It is used in multi-pitch climbing, rescue, and for ascending on rope.
Single pulleys: lightweight, for changing direction.
Ball bearing pulleys: smoother for heavy loads or frequent rappels.
Self-locking pulleys: used in safety and rescue systems.
High-efficiency pulleys: designed for winching and hauling systems.
Maximum load (kN): check the rated strength for your use.
Groove diameter: suitable for the diameter of rope or strap.
Type of bearing: ball bearings for smoothness, none for simplicity.
Weight and material: aluminum for lightweight, steel for heavy use.
Compatibility with your climbing belay equipment.
For purchase, prioritize reliable brands and transparent retailers. Also consider compatible accessories: carabiners, straps, and belay systems. You can also compare models based on your use: mountaineering, working at height, or rescue.
If you are looking to choose a reliable climbing strap, check the load specifications and CE certification.
For carabiners, look for safe and lightweight options: climbing carabiners from the best brands will facilitate your handling.
Some climbers pair pulleys with Black Diamond climbing and mountaineering gear for proven compatibility.
For lighting during night outings, consider a PETZL headlamp with fast delivery if you need to be operational quickly.
For camping and trekking gear, check out a C.A.M.P. camping and trekking selection that also offers technical solutions.
For specific mountaineering needs, Kong Sport mountaineering equipment is an option to consider.
For advanced belaying, some systems mention Edelrid climbing belay in their technical sheets; always compare features before purchase.
Cleaning: rinse with clear water after use in salty or dusty environments.
Lubrication: lightly apply a lubricant suitable for bearings if necessary.
Visual inspection: check for cracks, deformations, edge wear, and bearing operation.
Replacement: remove the pulley if it has suffered a significant impact or shows signs of wear.
The pulleys discussed here are also anatomical structures (pulley of the flexor tendons). In climbing, an overload can cause partial or total rupture, with sharp pain in the finger and inability to flex normally.
Sharp pain when bending a finger, often during a throw or strong grip.
Snapping sensation at the time of injury.
Swelling and possible bruising.
Simple test: if you can no longer close your fist normally, consult.
Initial rest and protection: splint or bandage to limit pulling.
Ice to reduce inflammation for 48 to 72 hours.
Consultation: a professional (sports doctor, physiotherapist) for assessment and imaging if necessary.
Progressive rehabilitation: isometric strengthening, then progressive loads and specific grip work.
Return to climbing: gradually resume with adaptations (avoid sharp edges and extreme loads) and follow the strengthening protocol.
For interventions at height, complete your kit with a suitable harness, certified ropes, anchor points, and robust pulley systems. Ensure you have climbing belay equipment and the necessary training.
A: Choose a ball bearing and high-efficiency pulley, sized for the load and rope.
A: Rinse, visually inspect, lightly lubricate the bearings if necessary, and replace if impacted.
A: Sharp pain, inability to flex the finger, deformation or significant bruise, consult quickly.
A: Harness, anchors, suitable pulleys, carabiners, and certified ropes; follow standards and training.
Choosing the right pulley depends on the use: rescue, mountaineering, winching, or simple direction change. Regularly maintain your equipment and take care of your fingers: prevention and appropriate rehabilitation often allow for a lasting return to climbing.
