Under Running (U/R) & Top Running (T/R) Bridge Travelling Cranes

Top running vs. underhung

This is the section of the bridge where the trolley and hoist system is installed and operates.

• Top-running configurations -Due to the fact that the trolley and hoist are supported by the runway support columns, top-running configurations are perfect for lifting extremely heavy loads.
• Under hung crane configurations - In an underhung configuration, the trolley and hoist are connected and run along the bridge's lower flange. Underhung trolley and hoist configurations are an excellent way to maximize space in your facility.

Top Running Cranes

Oveview - The crane bridge travels on top of rails mounted on a runway beam supported by either the building columns or columns specifically engineered for the crane. Top running canes are the most common form of crane design where the crane loads are transmitted to the building columns or free standing structure. These cranes have the greatest variation in capacity, span and service class and usually span the full width of the framing supports. These are available in both single girder and double girder configuration.

Basic structure of single girder top running crane

A top running single girder overhead crane is a type of crane that has a single beam spanning the width of a building and is supported by two end trucks. The hoist and trolley run on the bottom flange of the beam.

Advantages of a top running single girder overhead crane include:

• Cost-effective: Single girder cranes are generally less expensive than double girder cranes.
• Space-saving: Single girder cranes take up less space than double girder cranes, making them ideal for smaller facilities.
• Ease of maintenance: Because there is only one girder, maintenance is generally easier and less time-consuming.

Limitations of a top running single girder overhead crane include:

• Lower capacity: Single girder cranes typically have a lower capacity than double girder cranes.
• Limited span: Single girder cranes are typically limited in span compared to double girder cranes.
• Limited lift height: Single girder cranes may not be able to lift loads as high as double girder cranes.

Under running cranes

Overview - Under running or under slung cranes are supported by using a suspension type support which is connected to the bottom of the frame. The crane wheels are supported from the bottom of flange of the crane beams which act as a crane rail and usually only span a portion of the column-to-column span of the structure. Under running cranes are typically available in standard capacities up to 10 tons (special configurations up to 25 tons and over 90 ft spans). Under hung cranes offer excellent side approaches, close headroom and can be supported on runways hung from existing building members if adequate.

Basic structure of electric single girder suspension crane

The underhung bridge crane is basically similar to the top running electric single-girder crane. The main difference is that the underrunning crane is not supported and travelling on the top of runway beams between the spans of the building, but is suspended on the lower flange of the I-beam by using four pulleys mounted on the beam.

Advantages:

• simple structure, light weight, cheap price.
• And they can be installed on the ceiling or roof structure and used in relatively low factory buildings or warehouses, which is an cost-effective bridge crane by saving the cost of the crane supporting columns.

Limitations:

• There must be a roof truss or beam of sufficient strength to bear the self-weight, lifting load and dynamic load of the crane, so the lifting capacity of this underslung bridge crane should not be too large.
• At present, the maximum lifting capacity of undehrung bridge crane made by Chinese crane manufacturers and supplier are 10 ton.

Bridge cranes types based on the lifting devices

According to the pick-up device: such as hook bridge crane, grab bridge crane, electromagnetic bridge crane, container bridge crane, etc.

Overhead cranes are a type of material handling equipment that are used to lift and move heavy loads in manufacturing and industrial settings. There are several types of overhead crane attachments that can be used to increase the versatility and functionality of these cranes. Here are some examples:

Hook

grab

magnets

c hook

clamp

Spreader

• Hook Block: This is a basic attachment that is used to lift loads using a hook. Hook blocks are available in a range of sizes and capacities to meet specific application requirements.
• Lifting Magnets: These attachments use magnetic force to lift and move ferrous materials, such as steel plates or sheets. They are commonly used in metalworking and fabrication applications.
• Grabs: These attachments are used to lift and move bulk materials, such as sand, gravel, or scrap metal. They come in a variety of designs, including clamshell grabs, orange peel grabs, and bucket grabs.
• C-Hooks: These attachments are used to lift and move coils or other cylindrical loads. They are designed with a curved shape that allows them to securely grip the load.
• Spreader Beams: These attachments are used to distribute the weight of a load evenly across multiple lifting points. They are commonly used in applications where a load is too long or awkwardly shaped to be lifted with a single attachment point.
• Vacuum Lifters: These attachments use suction cups or a vacuum to lift and move materials, such as glass or plastic sheets. They are commonly used in manufacturing and assembly applications.
• Pallet Lifters: These attachments are used to lift and move pallets or other large containers. They are designed with fork-like tines that can be inserted into the pallet or container.
• Each type of overhead crane attachment offers its own unique advantages and limitations, and should be selected based on the specific requirements of the application.

Types of overhead cranes based on the uses or functions

According to the purpose or functions of cranes, the bridge cranes can be classified into general use bridge crane, metallurgical bridge crane, explosion-proof bridge crane and so on.

With gantry cranes, the trolley and hoist mechanism still travels along a bridge but is supported by legs rather than runways. They are therefore perfect for outdoor situations where installing columns is not an option. For instance, fixed- or track-mounted gantry cranes are frequently utilized for those applications in shipyards and railyards.

Gantry cranes are adaptable and come in portable and adjustable models. Gantry cranes are especially helpful in situations where lifting is not usually needed, like in a motor repair shop, etc.

Based on different classifications standards, the gantry cranes can be classified into different crane types:

There are many classifications of gantry cranes:

• 1. According to the structure: single main girder gantry crane, double main girder gantry crane, box type or truss type gantry crane.
• 2. According to the cantilever: single cantilever gantry crane, double cantilever, no cantilever gantry crane, etc.
• 3. According to the support method: rail-mounted gantry cranes, tire-type gantry cranes.
• 4. According to the pick-up device: hook gantry crane, grab gantry crane, electromagnetic gantry crane, etc.
• 5. According to the application occasion: general purpose gantry crane, shipbuilding gantry crane, hydropower station gantry crane, etc.

Single girder gantry crane & double girder gantry cranes

A single girder gantry crane is a type of gantry crane that has a single main girder spanning between two legs. It is commonly used in outdoor applications, such as in shipyards, construction sites, and storage yards.

Features of a single girder gantry crane include:

Selection of Gantry Cranes

1. Selection of single main girder and double girder gantry cranes

Choose according to the lifting tonnage, working speed and cargo size.

• The single main girder type is used when the span is less than 35 meters and there is no special requirement under 50 tons.
• Double-girder type is used when the width of the door foot is large, the working speed is high, or long pieces are often lifted.

2. Span and cantilever length - According to the main factors affecting the crane's self-weight, the span should be kept as small as possible while meeting other requirements.

3. Determination principle of wheelbase - Meet stability requirements; Transverse passability of goods; General wheelbase B=(1/4～1/6)S.

4. Determination of the distance between gantry cranes

During work, there should be a certain space between the external dimensions of the gantry crane and the cargo and transport vehicle passages in the yard to facilitate loading and unloading operations. Generally, when the transport vehicles are loaded and unloaded within the span, there should be a distance of more than 0.7m from the door legs. There should be a distance of more than 0.5m between the spreader and the transport vehicle when it is not working, and a distance of more than 0.5m when the goods pass through the door legs.

The overhead crane in your plant is one of the most crucial pieces of machinery. The majority of the labor-intensive work at your facility is physically done by it, therefore you need to have the equipment that will perform optimally for your needs. The size of your facility and your budget are only two factors to consider when selecting an overhead crane. You must carefully choose because there are various things to take into account, including your facility and the applications you will use it for.

Here are some fundamental guidelines to help you choose the best overhead crane equipment for your organization.

What is your facility conditions?

Take a thorough look at your facilities and decide what size and type of cranes will fit into the space the best before you start looking into a specific cranes.

This includes:

• Calculating the area that the crane will cover. You must measure any height limits or obstructions on the ceiling that can affect the functioning of the crane or violate OSHA rules in addition to the width and length of your structure.
• identifying any barriers that might restrict the crane's mobility. Examine your facilities to identify any potential impediments that can prevent appropriate and safe operation. OSHA regulations provide for at least 3 inches of clearance above and 2 inches of clearance laterally around crane equipment.

knowing how to install the crane in your facility. You might be able to employ a portable system that doesn't need any installation depending on your applications and the layout of your facility. However, if you want the installation of a permanent system, pay special attention to whether your facility has the foundation and/or structure required for a secure installation.

What is your lifting requirements?

The application for which you will require the overhead crane is the next most crucial consideration after determining how a crane might fit into your building. When considering your options for cranes, keep the following in mind:

• Crane capacity and working duty. Pay special attention to the amount of weight a overhead crane can support and evaluate it against your requirements. Even marginally exceeding a crane's capacity can be exceedingly risky. Decide if your lifting crane will need to be put to everyday use because the service duty or working class also dictates how frequently the crane can be used safely.
• Structural components .Aluminum or steel can be used to make cranes, with steel being more robust and long-lasting. Steel construction cranes are typically required for heavier-duty applications.
• Mechanical and electrical systems.

Additionally, consider the crane's capabilities and whether they align with the application. Your crane may be able to provide more reach and better flexibility around obstructions, for example, thanks to systems like a telescoping bridge. Your staff may be able to multitask or control the crane remotely if necessary thanks to the operator controls.
