Fixe Compact Pulley

A pulley is a simple machine that consists of a wheel on an axle, designed to help lift heavy loads by changing the direction of force. When you pull down on one side of the rope, the pulley allows you to lift the load on the other side more easily, making it an essential tool in climbing and rescue operations.

The working load refers to the maximum weight that a pulley can safely handle during normal use. For example, if a pulley has a working load of 5 kN (kilonewtons), it means you can safely lift loads up to that weight without risking damage to the pulley or injury.

Breaking strength is the maximum force or weight a pulley can withstand before it fails or breaks. For the FIXE pulley, the breaking strength is 22 kN, which is significantly higher than its working load. This means the pulley is built to handle much more weight than it is recommended to lift, providing an extra safety margin.

The claimed weight of the pulley, which is 3.2 oz, is crucial for climbers and rescuers who need to keep their gear lightweight. Knowing the weight helps users choose equipment that won’t add unnecessary bulk to their load, allowing for easier transport and maneuverability during climbs or rescues.

The FIXE pulley is recommended for climbing, rescue operations, and hauling. Understanding the recommended uses helps you determine if this pulley is suitable for your specific needs, ensuring you select the right equipment for your activities.

To determine if the FIXE pulley is right for you, consider the weight of the loads you plan to lift and the activities you will be engaging in. Ensure that your intended load does not exceed the working load of 5 kN, and that the pulley’s features align with your climbing or rescue requirements.
