FAQs
What is the Safe Working Load (SWL) of this pulley block?
The Safe Working Load (SWL) for this SecureFix Direct pulley block is 10 tonnes.
What size wire rope should I use with this block?
This block is designed for wire ropes with a diameter between 24 MM and 26 MM.
Is this pulley block suitable for marine use?
Yes, it is designed for lifting applications including marine use and features a heavy-duty construction.
How do I maintain the pulley block?
Clean with fresh water after use, especially in marine environments. Wipe dry and apply marine-grade lubricant to the sheave axle if it becomes stiff. Store in a dry area.
What does 'American Pattern' refer to?
American Pattern refers to a specific design standard for pulley blocks, known for its robust construction and reliability in various industrial applications.
Can I use this block for loads exceeding 10 tonnes?
No, it is critical to never exceed the 10-tonne Safe Working Load (SWL). Exceeding the SWL can lead to equipment failure and serious injury.
What is the purpose of the swivel oval eye?
The swivel oval eye allows the pulley block to rotate freely, aligning itself with the direction of the pull. This reduces stress on the rigging and ensures smoother operation.
Troubleshooting
Sheave does not rotate freely
Clean the sheave and axle. Apply a marine-grade lubricant to the sheave axle and rotate several times to distribute the lubricant. If the issue persists, inspect for damage or misalignment.
Wire rope appears to be slipping or binding
Ensure the correct wire rope diameter (24-26 MM) is being used. Check that the rope is not frayed or damaged. Verify the rope is correctly seated within the sheave groove.
Swivel eye appears stiff or difficult to move
Clean the swivel mechanism. Apply a suitable lubricant. Inspect for any debris or damage that might be impeding movement.
Visible signs of corrosion or rust
Clean the affected area with fresh water. If surface rust is present, it may be cleaned carefully. For deep corrosion, the block may need to be decommissioned due to potential loss of strength. Consult a rigging professional.

Setup, Compatibility & Care Instructions
Setup:
Inspect: Before use, visually inspect the pulley block for any signs of damage, wear, or deformation.
Attachment: Securely attach the swivel oval eye to a rated lifting point using appropriate shackles or connectors. Ensure the connector is rated for at least the SWL of the pulley block.
Rope Installation: Thread the wire rope (24-26 MM diameter) through the sheave, ensuring it runs smoothly without fraying or pinching.
Load Test (Recommended): If possible and safe to do so, perform a static load test below the SWL to verify correct function.
Compatibility:
Wire Diameter: This block is specifically designed for wire ropes with diameters between 24 MM and 26 MM.
Load Capacity: Ensure the total load does not exceed the 10 Tonne Safe Working Load (SWL). This includes the weight of the load itself, plus any dynamic forces.
Environmental: Suitable for general industrial and marine environments.
Care:
Cleaning: After use, especially in marine environments, clean the block with fresh water to remove salt and debris. Wipe dry with a clean cloth.
Lubrication: Periodically inspect the sheave for smooth rotation. Apply a suitable marine-grade lubricant to the sheave axle if rotation becomes stiff, following lubricant manufacturer guidelines.
Storage: Store in a clean, dry area away from corrosive substances when not in use.
Regular Inspection: Conduct regular visual inspections for wear on the sheave, sheave axle, and housing. Check the swivel eye for any signs of distortion or stress.
