You will find a huge list of different lifting gears and lifting equipment in the market, and it can be confusing to choose one from the so many for your lifting operations based on the industry you work in. Here is a comprehensive comparison of two most frequently used lifting gear used along with cranes – wire ropes and chain hoists.

About Wire Ropes
Most wire ropes are made with stainless steel material and are constructed by curling several metal wires together to make durable strands, which are again curled around each other into knots.
The strands are wrapped around a central core which is made of fiber, forming the final finished product which is robust and stable.

About Chain Hoists
Chain hoists as the name says are made from chains, which in turn are made from steel or zinc plated metal. The working is similar to that of ropes, the only difference being that the ropes are set of strands wrapped together while chain hoist looks like single chains linked together through hooks that have safety catches.

There are many similarities between ropes and chain hoists and that makes both of them suitable for different applications. Both are operated manually, can be customized for varied heights and are durable, enduring and easy to maintain in the long run. The inspection for both is quite an easy task. Both are built to last, strong and firm.
Advantages Of Wire Ropes Over Chain Hoists
While both ropes and chain hoists are made to last and are durable, there are several benefits that make ropes stand apart as the preferred solution in the lifting gear and equipment industry. The most significant plus point of wire rope is that it is constructed by stringing together multiple wires and strands. This ensures that the weight and hence the stress or pressure is spread evenly through the entire length of the rope across all the pieces, rather than the entire weight sitting on one strand alone.
Even if one wire or strand collapses, the lifting and descent task can still be completed without any major hassle, though the best practice is to stop the operations with broken rope. At least the immediate work at hand can be completed and then the work can be stopped.
With a chain hoist, if one chain in the link breaks, the whole chain hoist collapses and becomes useless at once. If this happens when you are in the middle of the job, this could cause the load to be damaged.
The case mentioned above is just an example to cite the advantage of rope over the chain hoist. Chain hoists are also made with a lot of care and provide high reliability and durability just like wire ropes. Both ropes and chain hoists have a long service life, and regular checks and thorough inspections will avoid any such mishaps.
Another advantage is that wire rope is stronger and can lift more weights. The lifting weights vary with each type of wire rope quality, but even then, the total capacity is about three times more for wire ropes (around 90000 kgs) as compared to that of chain hoists (about 30000kgs).
The last but not the least advantage is that wire ropes are more popular and have way more utility than chain hoists. From being used as decorative handrails of a home, to geothermal cables and internal support systems for construction projects, they are also used for internal cabling within any machinery and most commonly as equipment for the transfer of physical energy and power.
Are you confused about taking the right decision about choosing wire ropes or chain hoists? Don’t be. If you have doubts about the usage and suitability of any of these for your application, you should do your research and work with an experienced service provider to work with you through the process.
