Shandong Lisheng Machinery Co., Ltd. is a new generation enterprise dedicated to the hardware industry. It is located in Jining City, Shandong Province, the hometown of Confucius and Mencius. The company is a professional hardware supporting enterprise integrating design, research and development, production and sales. The main products are chains, wire ropes and their accessories: shackles, turn buckles, clips, rings, snap hooks and other forgings and castings, and accept drawings and samples for processing.
To ensure the continued reliability and performance of chain blocks, regular maintenance and care are necessary. Routine inspections should be conducted to identify and address any issues promptly. This includes lubricating the chain block's moving parts to minimize friction and prevent rust or corrosion. Cleanliness is also crucial, as dust, debris, or contaminants can interfere with the chain block's operation. Proper storage in a dry and secure area is essential to prevent damage and prolong the equipment's lifespan.
Chain block is optimized to bear vertical loads. When fixing or pulling a load, upper hook, bottom hook and load chain should be aligned in vertical position in order to bear the safety load.
According to Occupation Safety and Health Acts, hook and load chain of lever Hoist should be replaced if the hook throat opening is stretched by more than 10% or if load chain is stretched by more than 5%. Load chain, hook and chain pin which are directly bearing the load should be checked regularly since stretched length is difficult to measure through visual inspection. Lever Hoists are devices that are easily exposed to risk of overload, be careful when using such devices.
Safety is of utmost importance when working with chain blocks. Operators should receive proper training and adhere to safety guidelines to prevent accidents and injuries. Before using a chain block, it is crucial to inspect the equipment thoroughly. This includes checking the load chain, hooks, and connections for any signs of wear, damage, or deformities. Adequate load securing techniques should be employed, ensuring that the load is properly attached and balanced to avoid any potential hazards during lifting and moving operations.
Chain blocks have a compact shape and they are extremely lightweight which saves the time of mounting. Further, the ease of use makes chain blocks the first choice in the material handling industry.

<p>Put it in simple words, a Chain Block is a lifting device operated by pulling a hand chain. A Lever Block is a lifting device operated by rotation of a handle/ lever.</p>
<p>Also known as chain blocks or chain pulley blocks, chain hoists are used extensively to move heavy loads through chain pulling. While most chain hoists are operated by hand, lever blocks (or ratchet lever hoists) are operated by pulling a manual lever either forward or backward.</p>
<p>Chain block gives you the ability to lift huge loads up to 50 tonnes with ease by using mechanical advantage. Its working load limit (WLL) is greater than a lever hoist which lifts a load up to 10,000 kg.</p>
<p>The chain block contains two wheels or cogs in which the chain is wrapped around. Both electric chain blocks and manual chain blocks have the same fundamental functions - when the chain is pulled, it wraps around the wheels which adds torque to the lifting mechanism, pulling the item that is on the other end of the chain (usually with a strong hook) and lifting it off the ground - the wheels inside the block are how they are able to lift heavy loads - even when operated manually.</p> <p>A chain block has a strong chain for lifting objects and attaching hooks to, manual lifting blocks have a hand chain which can be used for pulling by hand to bring the load up (these are powered by motors in electric chain blocks), they also have a grabbing hook for applying the lifting load. Electric chain blocks are the most common method, however, manual chain blocks are commonly used to lift lighter loads as they aren&rsquo;t as expensive and are easier to move.</p>
