FAQs

What is the maximum wire rope diameter this block can accommodate?

This snatch block is designed to suit wire rope diameters from 10mm to 12mm.

What is the safe working load limit (WLL) for this snatch block?

The Head Load or Working Load Limit for this snatch block is 4 Tonnes (4,000 kg).

Can I use this snatch block for high-speed pulling operations?

No, this particular snatch block is fitted with a bush sheave, which makes it unsuitable for high-speed applications. It is best used for static or low-speed lifting and pulling.

What does 'snatch' mean in the context of a snatch block?

A snatch block is designed with a gate that allows the rope to be quickly placed around the sheave without threading it end-to-end. This 'snatching' action makes it faster to set up for redirecting loads.

What is the purpose of the swivel safety hook?

The swivel hook allows the block to rotate freely, preventing the wire rope from twisting or kinking during use. The safety latch ensures the hook remains securely attached to the anchor point or load.

Does a test certificate come with the product?

Yes, a test certificate is included and will be sent via email.

What are the overall dimensions of the snatch block?

The overall height is 358mm, the side width is 70mm, and the front width is 120mm.

Troubleshooting

Sheave does not rotate freely

Check for any debris or build-up around the sheave. Ensure the wire rope is correctly seated and not binding. If stiffness persists, inspect for damage or consider a light application of lubricant if appropriate for bush-type sheaves.

Gate does not close securely

Verify that the wire rope is properly seated within the sheave groove and not obstructing the gate. Ensure there is no damage to the gate mechanism or the locking pin/latch.

Hook safety latch is stuck or not closing properly

Clean the latch mechanism and check for any foreign objects. Inspect the hook for any bending or damage that may prevent the latch from functioning correctly. Do not use if the latch is compromised.

Rust or corrosion visible on the block

Clean the affected area with a wire brush and apply a suitable rust inhibitor or protective coating. Ensure the block is stored in a dry place to prevent further corrosion.

Pros and Cons

Pros

  • Robust construction suitable for heavy loads up to 4 tonnes.
  • Swivel hook allows for easy maneuvering and prevents rope strain.
  • Quick-attach gate simplifies rope management.
  • Lightweight design enhances portability and ease of use.
  • Conforms to safety standards (BS EN 13157:2004 + A1:2009).

Cons

  • Bush sheave is not suitable for high-speed operations.
  • Overall height of 358mm may be a consideration for space-constrained environments.
  • Requires specific wire rope diameters (10-12mm).

Setup, Compatibility & Care

Setup:

  1. Ensure the anchor point is rated for the load.
  2. Open the gate on the snatch block.
  3. Lay the wire rope (10mm - 12mm diameter) across the sheave.
  4. Close the gate securely. Ensure the safety latch is engaged.
  5. Attach the swivel hook to the anchor point or load as required.

Compatibility:

  • Primarily designed for use with wire rope of diameters 10mm to 12mm.
  • Working Load Limit (WLL) is 4 Tonnes. Always ensure the total load, including any mechanical advantage from rigging, does not exceed this limit.
  • Not recommended for high-speed applications due to the bush sheave.

Care and Maintenance:

  • Inspection: Regularly inspect the block for any signs of wear, damage, or deformation. Check the sheave for smooth rotation and the hook for proper closure.
  • Cleaning: Clean the block with a damp cloth. Avoid using harsh chemicals that could damage the materials. Ensure the sheave area is free of dirt and debris.
  • Lubrication: While the bush sheave is low-maintenance, a light application of appropriate lubricant may be considered if it becomes stiff, though this is typically not required for standard use.
  • Storage: Store the snatch block in a dry environment, away from corrosive elements, when not in use.
