Finding a crane that is perfect for the job is like finding a suitable apartment: you want it to be safe, functional, and last a long time.
True words, as finding one that offers safe and efficient lifting solutions can be daunting as it would further affect a business’s proficiency. The one thing common between Steel, Power, Aerospace, Ships and boats, Food, Construction, Railways or Automotive industries is, that they all entail light to heavy load lifting. Cranes are an invaluable piece of equipment to any such businesses. Not only do cranes assist with the process of building, but they also allow for the safe movement of goods. Then the most important decision must be partnering with a trustworthy crane manufacturer or supplier; the second, the type of crane to be purchased.
The most commonly used cranes are Gantry Cranes and Overhead Cranes. At times, they are even used interchangeably as they both perform more or less the same lifting and lowering functions. And so, it is imperative to know that they are not the same and entail certain qualities that differentiate them from each other. Knowing about these would save your business time and money!
Would you trust a mechanic who didn’t know the difference between a socket wrench and a combination wrench?
That is exactly why we must know the nitty gritty of the distinction between Overhead and Gantry Cranes- to not just get the best out of them, but also why one is more efficient than the other for your needs.
The main differentiation between the two is that an overhead crane would cost more as the design, manufacturing, and installation of an overhead crane system is an enormous investment; it requires substantially more structure to support the load which automatically increases the overall cost of the crane. They can set you back by 15000 dollars and can go over 100000 dollars !
While a gantry crane will be significantly cheaper to build due to its simpler built, as little as 2000 dollars and go up from there.
Overhead cranes make for perfect solutions for warehouses and factories that are crowded, their bridge offering efficient space utilisation, allowing positioning of a load any way you require with a 3-axis movement capability.
The general premise of Gantry cranes is similar to that of Overhead cranes, but the operation is different. Gantry cranes have a bridge that is supported by two a-frame rigid steel legs that rest on the floor.
also come with a bridge, but are either mounted on wheels or a track system, which makes them easier to be dissembled when mounted to the structure of the building, while also being mobile, offering the convenience of being moved inside or outside whenever needed.
Overhead Cranes take the cake when it comes to lifting some really heavy-duty objects with ease- some rated for up to one hundred tonnes, in a way that is safer than many lifting alternatives.
But Gantry cranes, though can lift heavy loads, are equipped to lift about 15 tonnes only, which is a far cry from Overhead crane’s 100!
Overhead cranes span the entire work area, allowing users to lift, move, and position materials throughout the area. It is because the bridge is mobile even while under load, providing vertical and horizontal movement capabilities. And hence, allow much more flexibility in their positioning of loads and provide greater utility.
Most Gantry Cranes are purposed to be stationary when loaded and mobile when unloaded. They primarily provide vertical and lateral lifting capabilities which means they can move a load up and over but not around.
Now that you have a better understanding of the differences between Overhead cranes and Gantry cranes, you would be better equipped with the right knowledge of what kind of cranes are suited to your business and load because safety begins with a good foundation.
