The Four Basic Designs of Overhead Cranes

Overhead Crane Design

Overhead cranes, otherwise known as bridge cranes is a type of crane that is used mainly in an industrial atmosphere. Overhead cranes do the strenuous tasks of removing extremely heavy and massive loads of materials through the overhead of a facility. Overhead cranes will never material handle at ground level, hence the name overhead. Overhead cranes generally lift, lower and move loads of materials horizontally. Parts of the overhead crane design include the truck, end ties, girders, a walkway and a drive mechanism, which carries the trolley and travels parallel to the bridge.

There are four basic types of overhead crane design which are: the top running crane, under running crane, single girder bridge crane, and the double girder bridge crane. Although they vary in design, they still do the same function, which is to move heavy loads of materials overhead. With a varied design look, the top running crane is mainly engineered to travel on rails, which are mounted on runway beams. These beams can be supported by freestanding columns or the existing columns of a building. The under running crane was designed to travel at the bottom flange of a runway beam. The roof’s structure of the building will more than likely support the runway beam for the under running crane. Single girder bridge cranes are simply made up of one girder, double end trucks and a trolley hoist. The trolley hoist runs along the bottom flange of the girder between the double end trucks.

Factors of an Overhead Crane Design

Double girder bridge cranes, which is a type of overhead crane design will allow the trolley hoist to travel on top of the rails that are mounted. Single girder bridge and double girder bridge cranes can be referred to as gantry cranes. However, gantry cranes will differ in the fact that they are actually attached to legs at both sides of the span. Gantry crane engineering will generally eliminate the required use of a column or an overhead runway system, which is a monorail system. Dealing with the fact that the system is monorail a trolley hoist assembly will be needed.

The use of monorails is determined by the service areas or even in applications where the loads being lifted, lowered and moved must follow an established path. Certainly, during the process, the trolley hoist would be mounted to the bottom flange of the monorail’s beam, just as it would in a single girder crane.

When working with any design of overhead cranes, it is very important to know the crane and the varied functions of the crane. Basic things like knowing about the products nickname, how and why it functions the way it does is proven crucial to maintaining and running an overhead crane. Also, it is crucial to get the most comprehensive training in order to properly service the whichever overhead crane machine type that will be used. Since overhead cranes are used for industrial uses and housed in factories, this means that if there is any chance or possibility that the machine might malfunction or cease to work, the factory may risk taking a loss financially.  It is imperative that the person operating the machine knows how to work the machine and there are thousands of programs that will help with teaching how to use overhead cranes. The different types of overhead cranes will do the same function or functions of lifting, lowering and moving heavy and massive loads of materials. Although, they perform the same function the overhead crane design will vary due to some tasks they can handle compared to another model design.

What Determines Overhead Crane Prices

Overhead Crane Prices | Overhead Crane System

If you are purchasing an overhead crane for material handling purposes, there are many factors to consider. Generally, overhead crane prices are determined by various factors. However, much of it depends upon the crane supply and demand equation.  Following are some factors that influence the purchasing of a crane:

  • Crane Machine Technical Specifications.
    5-ton crane price is obviously different with the price of a 2-ton crane. Prices vary according to specifications.
  • Manufacturing costs
    With different economic backgrounds, the production cost of a crane in different countries is varied accordingly.
  • Configurations of the crane that is the choice of the main components such as, gearboxes, drivers, and motors etc.
  • Volume or the quantity of the cranes. Prices may lower if the order is placed with large quantity.

Overhead Crane Prices | Additional Variables

Basically, the prices are determined by its specifications such as its tonnage, span, lifting height, working hours, crane operations and few other parameters. The tonnage basically refers to the largest lifting ability of the crane, mainly the maximum load a crane can bear. Whereas the span is the both ends of the crane which situated on the tall concrete pillars. And the working level is determined by the working hours and working conditions.

Also while buying a cost effective crane, the price is not the only factor to be kept in mind. The reliability of the crane is also a major factor. A crane is a long term investment. And a problematic crane might cost you a lot of money for repairing and maintaining purposes. A problematic crane might also increase the break time of your operation.

A major factor which determines the crane price the cost of the transportation. The transportation may cost which may even be higher than the price of the crane itself. If for example, you are importing a crane machine from overseas, then you’ll have to deal with the customs clearance cost. Then other cost includes the crane installation, maintenance, and parts cost.  Since the crane is a special piece of equipment which requires frequent maintenance; hence the crane parts are taken into consideration for a longer time.

What is an Overhead Crane System

Overhead Crane Prices | Overhead Crane System

An overhead crane system covers a rectangular area which moves load side to side and backward and forward. To move extremely heavy or bulky loads through the overhead space in a facility, instead of through aisles or on the floor, an overhead crane (also called an industrial crane, crane, or overhead traveling crane) is a machine that lifts, lowers and moves a load horizontally. An overhead crane system has high lifting capacities for load movement. There is a lifting device called a hoist which is mounted on a trolley for horizontal movement across a bridge beam connected to one or more horizontal girders that are supported at either end by end truck. The end trucks are attached at right angles to the girders and move on fixed runways. The horizontal travel of push type cranes is powered manually by the operator; alternatively, an electric overhead crane system is powered by electricity while some other cranes are air-powered. Crane travel is directed by an operator, either manually or with a wired pendant station or wireless controls that guide their electric- or pneumatic-powered travel. Typical uses include multi-directional movement of materials to support manufacturing, storage, loading or unloading activities inside a facility, outside in a yard, or at a railway or shipping port. Cranes come in a variety of styles and are used with a number of attachments to facilitate load lift, including:

Overhead Crane System | Types

Single girder crane – This utilizes a single bridge beam attached to the two runways and end trucks. This bridge beam or single girder supports a lifting mechanism or hoist that runs on the bottom flange of the bridge beam; also referred to as an under running crane or underhung crane.
Double girder crane – These cranes utilize two bridge beams set atop the runway end trucks. They typically incorporate a top running trolley hoist which moves along the top of the two bridge beams on its own set of wheels for increased headroom under the crane; also called a top running crane.
Box girder crane – Utilizes a four-sided box configuration in fabricating the bridge girder. This enhances the crane’s load capacity and accommodates wider bridge distances. Generally, they are utilized in pairs with the hoisting mechanism operating on rails attached to the top of each box girder.
Truss girder crane – A crane designed with structurally reinforced bridge girders for greater span and loading capabilities.
I-beam crane – Utilizes standard I-beam as the bridge girder and may also employ I-beams as the runway beams.
Straddle crane – Configured to straddle a load and often on wheels, these cranes are typically used in lumber yards or to move large containers at seaports.
Tower crane – This can handle very large, heavy loads at construction sites and for the loading and unloading of shipping containers.
