They can also be used for re-directing rope. This GMI Treble Block features a swivel eye and is specifically designed for use with 24MM fibre rope. The galvanised finish provides added protection against corrosion, ensuring durability and longevity in demanding environments. Specifications: Size - 6", SWL - 3 Ton, Suitable Rope Diameter - 24MM. Dimensions: A - 350MM, B - 100MM, C - 124MM, D - 25MM, E - 54MM, F - 114MM, G - 30MM. Conforms to BS EN 13157: 2004+A1: 2009. Test certificates are supplied via email.
This SecureFix Direct Treble Sheave Lifting Pulley Block is designed for professionals in construction, marine, and industrial settings requiring efficient and safe lifting or rope redirection. Its key benefit is the mechanical advantage provided by three sheaves, reducing the effort needed for heavy loads up to 3 tons. A potential caveat is its specific design for 24MM fibre rope, limiting its use with other rope types.

FAQs
What is the Safe Working Load (SWL) of this pulley block?
The Safe Working Load (SWL) for this SecureFix Direct Treble Sheave Lifting Pulley Block is 3 tons (3000 kg).
What type and size of rope is compatible with this block?
This pulley block is specifically designed for use with 24MM fibre rope.
Does the block come with a test certificate?
Yes, test certificates are supplied via email after purchase.
What does the galvanised finish protect against?
The galvanised finish provides enhanced protection against corrosion and rust, increasing the durability of the pulley block in demanding environments.
Can this pulley block be used for redirecting rope, not just lifting?
Yes, pulley blocks are ideal for redirecting rope lines to change the direction of a pulling force or to gain mechanical advantage in various tensioning systems.
Are there any specific safety standards this product meets?
This pulley block conforms to BS EN 13157: 2004+A1: 2009 safety standards for lifting equipment.
How do I clean and maintain the pulley block?
Clean with a damp cloth and avoid harsh chemicals. Inspect regularly for wear and damage. Store in a dry place when not in use to prevent corrosion.
Troubleshooting
Rope is difficult to pull or jams
Ensure the rope is correctly threaded through all three sheaves and is not twisted. Check that the rope diameter is exactly 24MM. Inspect the sheaves for any debris or damage that might impede rotation.
Pulley block shows signs of rust or corrosion
Clean the affected area with a wire brush and apply a suitable protective coating or lubricant designed for galvanised steel. Ensure the block is stored in a dry environment.
Swivel eye does not rotate freely
Inspect the swivel eye for dirt, debris, or damage. Clean thoroughly and, if necessary, apply a small amount of appropriate lubricant to the pivot point.
Load feels heavier than expected
Verify that the rope is threaded correctly to utilize the full mechanical advantage of the treble sheave system. Ensure the SWL of 3 tons is not being exceeded. Check for excessive friction in the system or the rope itself.

Requires proper rigging knowledge for safe and effective operation.
Test certificates are supplied separately via email, not included physically.
Dimensions are provided in millimeters, requiring conversion for some users.
Setup, Compatibility & Care
Setup:
Ensure the anchor point or mounting structure can safely support the combined load (object weight + dynamic forces).
Attach the swivel eye of the pulley block securely to the lifting point.
Thread the 24MM fibre rope through the three sheaves in the correct sequence to achieve the desired mechanical advantage.
Connect the free end of the rope to the load or the pulling mechanism.
Compatibility:
Rope Diameter: Strictly designed for 24MM fibre rope. Using ropes of different diameters may compromise safety and performance.
Load Capacity: Do not exceed the Safe Working Load (SWL) of 3 tons.
Care:
Inspection: Regularly inspect the pulley block for any signs of wear, damage, or corrosion. Pay close attention to the sheaves and the swivel eye.
Cleaning: Clean the pulley block with a damp cloth. Avoid using harsh chemicals that could damage the galvanised finish.
Lubrication: While not always necessary for basic use, light lubrication of the sheave bearings can improve performance over time, following manufacturer recommendations if available.
Storage: Store in a dry place when not in use to prevent premature corrosion.
