Frequently asked questions
What is a rope block or Manilla Rope Block?
A pulley block designed for soft fibre rope (manila, polyester, polypropylene). Used to change the direction of a line or to multiply pulling force in a block-and-tackle arrangement.
What does SWL mean on a Manilla Block?
SWL stands for Safe Working Load, the maximum load the block is rated to lift in normal use. The figures in the spec table above are SWLs for each rope size and sheave count.
What’s a sheave?
A sheave is the grooved wheel inside a pulley block that the rope runs over. A single-sheave block has one wheel; a treble-sheave block has three. More sheaves means more mechanical advantage when used in a block-and-tackle setup.
What rope diameter matches which sheave size?
See the spec table above. Each rope diameter from 10 mm to 24 mm has a matched sheave diameter from 65 mm to 150 mm. Using a rope outside the matched size will reduce SWL and accelerate wear.
What’s the mechanical advantage of a 2- or 3-sheave block?
In a typical block-and-tackle arrangement, mechanical advantage scales with the number of rope falls supporting the load, not just the sheave count. A double-sheave block in a moveable arrangement typically achieves around 4:1; a treble around 6:1. Exact ratios depend on rigging configuration. Speak to our team for application-specific advice.
Can I use a Manilla Block with steel wire rope?
No. Manilla Blocks are designed for soft fibre rope. For steel wire rope applications, use a snatch block instead, the sheave geometry, groove, and bearing are designed for wire rope.
What’s the difference between a sheave wheel and a Manilla Block?
A sheave wheel is the rotating grooved component on its own (sold as a replacement part). A Manilla Block is a complete assembly, sheave(s), shell, axle pin, and attachment fitting, ready to rig.
How do I order a Manilla Block or get a custom configuration?
Send your spec, rope diameter, required SWL, sheave count, and attachment type, to [email protected] or call 011 345 8800 . Standard configurations from the table above are typically in stock; custom configurations are quoted with lead time on request.
