What is an Overhead Crane? | Cranes 101
I’M going to teach you everything you could possibly need to know about Overhead Cranes. Welcome to Cranes 101. I’M Chris Whitney with Progressive Crane With over 40 years of Overhead Crane manufacturing and engineering We’ve come into contact with all different sorts of manufacturers that use Overhead Cranes. Some know cranes better than I do. Some have no experience.
What-So-Ever We’ve come across parties that need a little more hand accommodating and facilitate filling in the spaces. That’S where I come in, Starting with “. What is an overhead crane, ?” And drilling down to some of the codes and the rules of procedure? Our goal is to help you establish a basi height knowledge of overhead cranes, So we can help.
You pick the best overhead crane for your application. You ready, Let’s Get Started. Mostly, an overhead crane is a machine That allows you to lift a piece of fabric And is moving forward from one location to another location. Using precise motion. You’Ve actually been around cranes, your entire lifetime Look familiar That’S all an overhead crane is Aside of meeting your life easier.
Overhead cranes are used for two main purposes: Efficiency and Safety. An overhead crane can work up to three times more efficiently Than a group of proletarians or two tow engines.
They can also be used in extreme environments to prevent bodily injury to the operator Sure they search cool, But overhead cranes can be used to raise the level of safety as well as productivity. So now you know approximately what a crane is. Let’S determine some of the components: Let’S start with the most basic component: The Hook The hook is used for attaching your quantity to the crane, so it can be raised and moved. The Hoist is what moves the hook up and down That is organized to the bottom of your bridge.
What moves your crane from side to side across the bridge is your trolley, Your bridge is your load endure radiation that the streetcar rides on That can be Top operating or Under running configuration Your runway beam is what allows your bridge to travel from one end to the other End Trucks are what physically drive your connection down the runway. Think of a auto They have wheels and motors that drive them. The control panel attached to your bridge crane.That’s. What transports the signal to your point, trucks That tell it to move through a push button or a radio controller that the adventurer is supporting on the floor.
Or in the CAT There are two types of Electrification organisations: you’ll check with a crane. First, you have your runway electrification, Which is what delivers capability from the building to the crane And then across the bridge. You have a festoon system or conductor forbid system. That fetches superpower and control to the hoist trolley.
Before we inspected the different kinds of cranes, if some of these periods are new to you, It would be a good time to go back and look through what we catered. Our goal is to teach you And duplication, frequently works best Overhead cranes come in all figures sizes and capacities.
A few things to consider when sizing an overhead crane, What’s the heavines, you are lifting, What’s the size of your house, Is it a new building and is it adjustable You’ll want to look at the distance of your crane
What is the length of your runway? Is it going to be indoors or outdoors? How many times per hour? Are you going to be performing a lift, And what percentage of that capacity are you going to be lifting Once you figure out what you need?
It will help narrow down your search. I’M going to break down the different types of overhead cranes And we’re going to start with the most complex one. The bridge crane, A connection crane method includes two overhead runways and a bridge that journeys on it. It also includes the hoist and streetcar that razzs side-to-side and can be in a single or double girder configuration. So what does all this “ Single ” and “ double girder ” nonsense?
A single girder crane is a matter of a single rafter that journeys above or below the end trucks based on whether it is a top running or under running configuration Typically, this type of crane is less expensive due to lower freight cost, simpler facility, A simpler hoist streetcar layout, as well as it allows for lighter runway rafters. A double-girder crane design consists of two connect rafters And again can be top-running or under-running. This type of crane is a little more expensive than a single girder, And that’s normally, due to the freight being a little bit more for shipping. Two connection rafters Too takes a little bit longer to install, has a more complex, hoist and trolley intend And too will typically require a heavier-duty runway. Beam. Bridge cranes fall into two categories: You have Process Cranes and you have Modular cranes.
A process crane is build for specific needs, Typically on ceaseless enterprise in a Steel Mill, Auto industry or container yard. Cmaa categorizes these as D. E. or F duty Cycle Cranes.
Basically, that means that this crane is being used for 10 to 20 or even more heaves per hour at 50 to 75 percent of the rated capacity Modular cranes are usually found in smaller manufacture works. Often, you’ll verify these in a machine shop or a smaller mill. They’Re, most economical and inexpensive CMAA typically categorizes these cranes as a C or below
But with a little extra engineering are also welcome to be a Class D work. Frequently with these parts, your lifting 40 % of the rated capacity For five to ten face-lifts per hour at most, So a connection crane doesn’t sound right to you Lucky for you. We’Ve come other options: A gantry crane is like a bridge crane Exclusively instead of being suspended in the air has legs That ride on an embedded railing on the floor or can also ride on the concrete Gantry Cranes are versatile.
You can use them in outdoor prepares in rail gardens and ship yards with a high duty cycle When rails and articles cannot be used.
Or you’ll see them inside when an overhead impedimentum restrictions you from expending a aqueduct crane. Monorail cranes are used in production on Assembly Lines where work is moved from one work station to another. Without having any side motion Like a single girder connect, the streetcar journeys on the underside of the rafter And allows you to transfer your ladens In addition, you can also use a road permutation which will allow you to go from one monorail to another or assign a load from one rail to another. Jib cranes come in a number of different configurations And are typically used when an overhead rail system is not available for a crane.
They come in a number of different capacities, distances and widths, Depending on your need. they can be wall prepared or they can be floor prepared And normally give you 180 positions to 360 severities of travel. A workstation crane is used for an individual user. They can stray from capacities 250 pounds to two tons And can be free, standing or ceiling hung, depending on the cavity that you have The key here is the ergonomic use and versatility. So that’s it.
I know it was a lot of information, but this was supposed to be a crash course into everything that is overhead cranes. As we move further into the cranes, 101 sequences we’ll take a deeper dive into each type of crane and find out what stimulates them click.
