3. Components del producte

Figure 1: Petzl Mobile Pulley P03A. This image displays the compact, gold-colored pulley with its main components visible. The side plates are made of aluminum, and the sheave is a polished metal. Markings for maximum working load (WLL 5kN and WLL 2.5kN) and CE certification (CE 0197) are clearly visible on the side plate. The Petzl logo is also present.
The Petzl Mobile Pulley (P03A) consists of the following primary components:
- Side Plates: The main structural body of the pulley, typically made from aluminum alloy, providing strength and durability.
- Sheave: The wheel around which the rope runs. This model features a sheave mounted on self-lubricating bushings for good efficiency.
- Eix: The central pin that holds the sheave and side plates together.
- Punts de connexió: Openings in the side plates designed for connecting carabiners or other connectors.
- Marques: Engraved or printed information including the brand (PETZL), model number (P03A), CE certification (CE 0197), and maximum working load limits (WLL 5kN for hauling, WLL 2.5kN for deviation).
4. Configuració i instal·lació
Proper setup is crucial for the safe operation of the Petzl Mobile Pulley. Always ensure the pulley is correctly integrated into your system.
- Disseny del sistema: Before installation, plan your hauling or deviation system. Ensure all components, including ropes, carabiners, and anchors, are compatible and rated for the intended loads.
- Adjunt: Connect the pulley to an appropriate anchor point or other system components using a suitable carabiner. Ensure the carabiner is fully closed and locked. The attachment points on the pulley are designed to accommodate standard climbing carabiners.
- Instal·lació de corda: Open the side plates (if applicable, for this model the side plates are fixed, so the rope is threaded through the opening). Thread the rope over the sheave. Ensure the rope runs smoothly and is not twisted or snagged. The sheave is designed for ropes up to a certain diameter (refer to specifications for exact diameter range).
- Direcció de càrrega: Position the pulley so that the load is applied in the intended direction, aligning with the sheave's axis of rotation. Avoid side loading or eccentric loading that could damage the pulley or compromise its efficiency.
- Comprovació prèvia a l'ús: Before applying any load, perform a thorough check of the entire system. Verify that all connections are secure, ropes are correctly routed, and there are no obstructions.
This pulley is designed for use with textile ropes. Do not use with wire ropes or cables.
5. Instruccions de funcionament
The Petzl Mobile Pulley is designed to reduce friction and improve efficiency in rope systems. Its primary applications include:
5.1. Hauling Systems
When used in a hauling system, the pulley facilitates lifting loads with less effort. The maximum working load for hauling is 5 kN (2.5 kN x 2, indicating the load on each side of the pulley). Ensure the rope diameter is compatible with the sheave.
- Integrate the pulley into your mechanical advantage system (e.g., Z-drag, simple 3:1).
- Ensure the rope runs freely over the sheave without rubbing against the side plates.
- Apply force smoothly and consistently. Avoid sudden jerks or impacts.
- Always maintain control of the rope and the load.
5.2. Desviacions
For deviations, the pulley redirects the rope's path, which can be useful for managing rope angles or creating specific rigging configurations. The maximum working load for deviation is 2.5 kN.
- Attach the pulley to a secure anchor point to redirect the rope.
- Ensure the angle of deviation does not create excessive force on the pulley or anchor.
- Verify that the rope does not rub against any obstacles after being redirected by the pulley.
Always monitor the pulley during operation for any signs of unusual wear, noise, or malfunction. If any issues are observed, cease operation immediately and inspect the equipment.
6. Manteniment i emmagatzematge
6.1. Inspecció
Regular inspection is vital for the longevity and safety of your pulley. Inspect the pulley before and after each use, and at least once every 12 months by a competent person.
- Side Plates: Check for cracks, deformation, sharp edges, or excessive wear.
- Sheave: Ensure the sheave rotates freely and smoothly. Check for grooves, flat spots, or damage.
- Eix: Verify the axle is secure and shows no signs of bending or corrosion.
- Marques: Ensure all product markings (brand, model, WLL, CE) are legible.
Any pulley showing signs of damage, excessive wear, or corrosion must be immediately retired from service and destroyed to prevent accidental reuse.
6.2. Neteja
Clean the pulley with fresh water and a mild soap solution. Rinse thoroughly and allow it to air dry completely in a shaded, well-ventilated area. Do not use harsh chemicals or solvents.
6.3. Emmagatzematge
Store the pulley in a cool, dry, dark, and well-ventilated place, away from direct sunlight, extreme temperatures, humidity, corrosive substances, and sharp objects. Avoid storing under compression or with other equipment that could cause damage.
7. Solució De Problemes
