Lifting equipment refers to any types of industrial equipment that has the capability of lifting a load to a specific vertical height. From the first pulley and rope system that was used in the medieval times (and probably even before that) to the mechanical behemoths we’ve come to operate in construction sites today, we’ve certainly come a long way in our development of these tools.
Like all machines, they were developed to replace manual labor and make the task of lifting a particular load to a new height far easier and much more efficiently, and we were more than able to achieve this goal.
However, that doesn’t mean every kind of lifting equipment is the same. There are a lot of things that set them apart from each other.
The most basic of classification that one can apply to modern lifting equipment is by their working principle, i.e. the fundamental law of physics or mechanics they use to carry their load. There are the more primitive of principles of play in the electric hoist, which uses the generic rope-pulley system only upgraded by using a robust electric motor and able to get more work done. Another popular mechanism that’s used in lifting today is the scissor mechanism in scissor lifts that use the gain in height from “closing the scissor jaws” to lift their load.
Besides these two, the most popular of mechanisms at play in modern lifting equipment is the concept of hydraulics, which works on the fact that you can obtain a high output of lifting force with the application of only a small amount of force at the user’s end thanks to the incompressibility of liquids in a chamber.
Modern lifting equipment uses these principles in combination or separately, along with pulleys, levers, etc. to produce the desired lifting result.
Lifting equipment can also be differentiated according to what they’re used for, depending on what they’re used to lift and where they’re used.
As far as the load goes, there are only two kinds of things these machines are used to lift: people or equipment. A great example of lifting equipment that is strictly used to carry people up is an elevator, which is an ordinary and necessary installment in almost every tall building built today. An example of lifting equipment that lifts only equipment, however, is that of a crane or forklift, which are used mostly in the construction and other heavy industries to carry heavy materials and raise them to higher platforms.
Another industry where lifting equipment is heavily used is the auto-maintenance industry where tools like transmission jacks and column lifts are essential to raising the car to a decent height so that a mechanic can safely work on the parts on the car’s underside.
The use of these tools in this industry has become so popular that even if these systems fail, spare parts for column lifts and jacks are readily available, as well as services that can fix them for you.
