Difference Between a Pulley Block and a Snatch Block
Difference Between a Pulley Block and a Snatch Block - All Lifting


Pulley blocks and snatch blocks are both pulley blocks; these lifting tools have a wheel on an axle designed to help you lift heavy items up to 30 tonne. Pulley blocks give direction to the rope while loaded; they are able to increase the line pull or lifting capacity of a hoist or winch by multiplying the number of lines. The difference between them is that a pulley block is constantly closed and you must thread the line through the axle while the snatch block is designed to open with a gate on the side so the wire rope can be fitted easily as shown in the below pictures.

Both, pulley and snatch blocks will help you to facilitate your lifting operations. There is no specific reason why you should buy one over the other; people choose which ever one works best for them, often based on personal preference. When used in conjunction with a winch, a snatch block can increase the winch’s power considerably, allowing for a smoother, easier winching process. You will be able to find many different blocks in the market. Snatch blocks are more often preferred with a quick list below for your reference.
