INSTRUCTIONS & CAUTIONS
Inspect Before Use
Always check the half side block for any visible damage or wear before using it. Inspect the sheave, side plates, and hook to ensure there are no cracks or rust. A quick inspection can prevent accidents and keep your equipment running smoothly. If any part looks damaged, replace it immediately to avoid risking failure during use.
Proper Load Capacity
Never exceed the recommended load capacity for the half side block. Check the manufacturer’s specifications for the safe working load (SWL) and make sure the load doesn’t surpass this limit. Overloading the block could lead to serious damage or even catastrophic failure. Always factor in dynamic loads when calculating the total load.
Ensure Proper Lubrication
Lubricate the sheave and other moving parts regularly to minimize friction and wear. A well-lubricated block operates more smoothly and lasts longer. Use the right type of grease or oil as specified by the manufacturer and avoid over-lubricating, which could attract dirt and debris.
Secure the Block Properly
Always make sure the half side block is securely attached to the lifting system before use. Double-check that the shackle or hook is properly engaged and that the rope or cable is correctly threaded through the sheave. If the block is not securely fastened, it can come loose under load, causing injury or damage to equipment.

OUR REVIEWS



FAQ
What is a half side block, and how is it different from other types of blocks?
A half side block has an open side design, making it lighter and easier to handle compared to fully enclosed blocks. This design reduces weight while still maintaining strength for lifting heavy loads. It’s perfect for applications that require quick reeving and easy rope changes, offering a balance of strength, efficiency, and portability.
What are the advantages of using a half side block in rigging?
The main advantage is reduced weight without sacrificing strength. The open side design makes it easier to install and remove the rope, saving time on the job. It also helps prevent rope binding, ensuring smoother operation. These blocks are ideal for quick, high-efficiency operations in industrial, construction, and marine environments.
How do I select the right half side block for my lifting project?
To select the right block, you need to consider the working load limit (WLL), rope size, and the conditions it will be used in. Ensure that the block’s specifications match your rigging setup. Powerful Machinery offers customized half side blocks, so we can work with you to create a solution tailored to your needs, ensuring optimal performance and safety.
Can the half side block be used with different types of ropes?
Absolutely! Our half side blocks are compatible with a wide variety of ropes, including wire ropes and synthetic ropes. The sheave is designed to accommodate different rope sizes, ensuring smooth operation no matter what type of rope you’re using. Be sure to match the rope size with the block’s specifications for optimal performance.
How quickly can I receive my half side block order?
We prioritize quick delivery and efficient logistics to ensure you get your order on time. Standard shipping typically takes about 7-14 days, but we also offer expedited shipping options if you need your blocks sooner. If you’re placing a customized order, the lead time will depend on the complexity of your specifications, but we always work to meet your deadlines.
