About the Snatch Blocks
There are a range of blocks to suit different applications, snatch blocks enable the wire rope to be easily fitted as they open up to insert the rope instead of pushing it through. Some blocks have bronze bushes whilst others have ball bearings and come in single sheave or multiple sheave varieties.
Snatch blocks can be attached to anchor points through a choice of different fittings, with different models offering different means of securing the unit in place for safe lifting.
For example, you may prefer to opt for a snatch block that has a shackle attachment. This is appropriate if you are looking to create a semi-permanent setup where you will not be removing the block very regularly. Alternatively you may prefer a snatch block with a hook installed. This snap hook approach allows for quick detachment and is ideal for temporarily affixing the block in place where it is needed most.
When using sheave blocks there are some common safety procedures and calculations to follow, in particular the angle between the load and the line which affects the load on the block, and the number of sheaves and lines used, here are the basics.
Each pulley block in this category is built to last using the best materials available and with the most precise attention to detail, as you would expect from products sold by Lifting Gear Direct.

A snatch block provides a means of changing the direction of pull as well as increasing the pulling capacity when using the correct sheave block technique. They are typically used with winches and are quicker to fit than a sheave block thanks to the movable side plates for quick rope insertion.
Sheave blocks, like snatch blocks are used to change the pulling orientation and increase capacity. However the rope can be a little more tricky to thread through than a snatch block but there are single, double and triple sheaved blocks available, thus allowing for multiple ropes to be used
When using sheave blocks or snatch blocks the angle of the rope can have an effect on the overall safe working load limit. For example on a 2000kg lead line at a 45 degree angle will be reduced to 1840kg
