These blocks are usually used in Fishing applications. A snatch block has a side plate sometimes called a cheek plate, that can be opened for easy insertion of cable without having to remove the load or fittings from the end of the wire. The process of inserting a line into a block is called reeving.


A pulley system is used in conjunction with wire rope or other types of rigging ropes, and can be opened on one side to quickly and easily insert a wire rope without having to remove the load or change the direction of the cable, by looping the rope through the pulley (around the sheave) several times before hooking to the object.

China LG Supply offers to snatch blocks to fit various marine projects. They feature steel and wooden styles.

How To Use Snatch Block?

You can use the snatch block in a variety of off-road rescue situations to increase the power of the winch, to change the direction of pull of the winch, to pull a stuck vehicle from different angles, and to relieve some of the pressure build-up on the winch.

Winch Pull




You can achieve an increase in winch pull by having the winch cable go around the sheave of the Snatch block and back to the car. Using a tree as an anchor doubles the winch's pull.

You can also use the winch of another vehicle instead of using the tree as an anchor. you need to connect the snatch block to the vehicle at a solid recovery point with a release buckle, run the winch cable from the recovery vehicle through the release buckle on the stuck vehicle and connect it back to the recovery vehicle.

Alternatively, you can use more than one Snatch block, for example by fitting a second Snatch block to the recovery vehicle and passing the winch cable through the Snatch block and back to the stuck vehicle, which can triple the winch pull.


Redirect




Snatch blocks can be used to redirect the winch pull. Sometimes it can be a challenge to use the winch of the rescue vehicle directly to pull the stuck vehicle, but if you find trees, boulders, or any other large object around that can act as an anchor, have the rescue vehicle apply pull at a 90-degree angle to the stuck vehicle and use the Snatch block to redirect the pull of the recovery vehicle so that it can still pull the stuck vehicle in the right direction.

Pulley Blocks for Fishing and Trawling

Pulley Blocks for Fishing and Trawling

Most of the Pulley blocks for fishing and trawling are wooden snatch blocks, of which there are single sheaves, double sheaves and triple sheaves in terms of the number of sheaves. The other end of the snatch block is also available in various forms, including eye, hook, swivel hook, swivel eye, shackle, and a type of shackle that can be assembled later on without any attachment parts.


Of course, there is more than just wooden snatch blocks for fishing and trawling, there are also steel pulleys, which generally have Eye, hook and other attachment fittings and are finished with electro-galvanized, hot-dip galvanized, powder coated, etc. to protect the outside of the pulley from corrosion to a certain extent.


Pulley and Snatch Block Safety

Force

When used with a winch, there is a lot of force passing through the Snatch block and the pressure on the rope can be twice the actual load being towed. If the pressure is too high and the load is too high, the Snatch block can fail and subsequently fail, which can have a slingshot effect and cause significant damage. It is therefore essential that the equipment is set up correctly and that all components are connected safely. Of course, the anchor itself must also be very secure and safe.

Follow

It is important to follow safety procedures when using the Snatch block, which can be dangerous if used incorrectly.
