A Chain block is a mechanism for lifting and lowering heavy loads utilizing a chain. The chain block has two wheels around which the chain is wrapping. When you pull the chain, it wraps around the reels, beginning to lift an object attached to the rope or chain with a hook. You can also attach chain blocks to lifting straps or chain bags to lift the load more evenly. The chain block includes a hand chain and a bracket. Most chain blocks use motors in their operation, but also you can use manual chain blocks. First, you have to connect the chain block to the load utilizing the clamp. When you pull the hand chain, it strengthens its grip around the wheel and making an inside loop in the mechanism, causing the tension to lift the load off the ground. Because of their carrying capacity, chain blocks often work in workshops to easily remove car engines.
Since only one person is needed to operate a chain block, chain blocks are a remarkably efficient way of doing jobs that may require more than two people. You can use chain blocks on construction sites to lift heavy loads at the highest level, assembly-line factories to lift heavy objects on a belt and vice versa, and sometimes even lift cars on dangerous terrain. Chain blocks are available in different capacities and are therefore suitable for a wide variety of functions. You can get chain blocks with a load capacity of up to 20 tons. Although choosing the right chain block that suits your needs is not easy, we hope that the detailed guide below provides you with the information you need to make the right choice.
What is the difference between a chain block and chain hoist?
You can only use chain blocks for vertical lifting. If you load them laterally or use them horizontally, the mechanism may lock up. On the other hand, lever hoists have the advantage that they can lift loads both horizontally and vertically in most positions. You can as well use the lever to tighten and tie cargo for transportation.
A chain block normally works manually, consisting of a combination of internal gears and a chain. The operator pulls a hand chain that turns the pulley mechanism on the elevator to move the load. At the end of the load chain, there is a hook for easy attachment to the item and an upper hook for hooking the chain hoist to a suitable support.
Unlike a chain block, a chain hoist has a lever handle on the chain block side with an internal gear and a ratchet system with a load chain. The lever lock moves the lever up and down to activate the ratchet and the ratchet system, causing the load to move a certain distance employing a crank. You can easily change the internal gear's direction to carry the load up or down as you may require. There is a hook at the end of the lifting chain that allows easy attachment to the object and a clip that attaches to the lever hoist housing to secure it and secure the support.
Chain hoists are available as manual or electric mechanisms, generally lifting from 250 kg to 20 tons and lift heights of 3 and 6 m. In contrast to the chain block, the lever hoist is available in standard lengths of 3 or 1.5 meters, and the general load limits are 250 kg to 9 tons. Of course for both other sizes and lifting capacities can also be available upon request.
Factors to consider when choosing the right chain block
Deciding upon the appropriate capacity
If you enter the chain block arena without knowing your lifting needs, this is probably the biggest mistake you could make initially. In general, a block's lift capacity ranges from 250 kg to 20 tons. First, determine the capacity requirements regarding your needs. You can find chain blocks that have a capacity of 50 tonnes or more. It would be of help if you chose the ability based on the weight of the heaviest object you plan to lift on the chain block.
Trolley Mounted or Fixed Mounted
You can choose a fixed bracket (mounted on the hook) or a chain mounted on the trolley. Assembled trolleys are useful when you want to move the load on the beams. Hook latches are helpful when the blocks remain static in one place for a long time. Talking to gear sales experts can help you clarify your doubts and questions about which is best for you.
Standard Interchangeable Parts
If you are looking for long-term use, rather than just short-term performance always check that it is possible to change the standard parts of the chain block easily. It may seem insignificant now, but thank us when wear is inevitable. These replaceable parts allow for quick repairs and a quick return to regular operation. Standard parts also guarantee easy replacement - if you choose a common chain block with interchangeable spare parts, you have the advantage of being able to replace them at any time. Therefore, it is advisable to select one with spare parts available in stores and simple to replace in case of failure.
Prioritise a spur gear mechanism over worm gear
Choose a chain hoist with the most effective spur gears mechanism as it offers greater load capacity with little effort. Make sure that the lifting wheel housings are deep enough for the chain space to move smoothly, freely, and without obstacles.
Purchase chain hoists with built in overload protection
We recommend you purchase chain hoists with a factory configuration of an overload protection system, especially if you are not sure of the weight of the objects you will be lifting or dragging.
Chain length
You need to have the right information on the chain length that you require before committing your money. As a rule of thumb, measure the height of the lift. Ensure that the lift chain's size matches the lift height and that the hand chain is roughly two feet shorter than the lift chain length. For instance, if the lift chain block's length is approximately 20 feet, the hand chain should be around 18 feet.
However, it is possible to keep the lift chain's length longer than its size. In particular, chain blocks contain methods that you can use to determine if the length meets your needs. Check for details in the product description and buy only when the chain's length suits you.
The construction material of the load chain
The chain block loading chain must feature a grade 80 alloy steel. When buying a chain block, the most important thing is to check that there is no welding on the load chain.
Budget
You have to consider your budget when purchasing equipment, and the chain hoist is no different. However, it is essential not to be short-sighted and just purchase the cheapest and expect the best. You need to make sure that your service provider is fully supportive in terms of experience and parts if something goes wrong. Ensure your supplier is an OEM or official distributor of a recognized product.
Warranty
When choosing a chain block, be sure to check the product terms and warranty period.
