A gantry crane uses its own legs for support rather than a beam or other fixture within the facility. Indoor gantry cranes may have a single or multiple girders, with multiple girder models better suited to heavy-duty work. There are four primary styles of gantry crane, each suited to specific applications:
- Full gantry cranes.The most popular style, full gantry cranes have two legs that run along a track. That track is typically embedded into the work surface, so trucks, forklifts, and other vehicles can easily cross it.
- Semi gantry cranes.This type of gantry crane has one leg. The other side of the crane runs along a track on the wall to save space. Both full and semi gantry cranes are common in heavy-lift manufacturing applications.
- Portable gantry cranes.These cranes are fixed on wheels, allowing them to be moved throughout a facility and easily stored out of the way. Portable gantry cranes are best-suited for lighter lifting tasks. Portable gantry cranes are often used to hold a load so workers can easily access it for maintenance or modification. Portable gantry cranes have a myriad of uses in manufacturing and warehouse environments.
- Adjustable gantry cranes.Another light-duty option, adjustable cranes allow adjustment of the span or the height of the cranes to manage different types of loads. These cranes see frequent use in warehouses and in manufacturing environments with variable loads.
Primary Factors that Affect Gantry Crane Design
It’s important to choose the right crane for the job. Depending upon your application, you may require a custom gantry crane design. This ensures the crane suits its intended working conditions, facility layout, and load requirements. The following factors impact gantry design:
Arm and Span Length
When determining arm and span length, first consider the size of the work area and the size and weight of the maximum load. This is where gantry crane design begins. Determine how big the crane needs to be, and how much weight it must support or lift reliably.
Indoor or Outdoor Use
The operating environment of the crane will determine the ideal materials and finishes used to fabricate its various components. Consider temperature extremes and fluctuations, weather exposure, and harsh operating conditions to help guide the selection of the proper materials and finishing processes.
Fixed or Rotating Axle End Trucks
Indoor cranes typically use fixed axle end trucks because they largely stay in one place. Outdoor cranes may need to move across yards where they can gather dirt and debris that will impact performance. Rotating axle end trucks have fewer parts and use lubrication to block dirt and debris.
Gantry cranes are versatile, cost-effective, and easy to maintain, but they move loads slowly. If speed is a priority within your operation, you may need to consider a different type of crane. Attempting to move a load more quickly than a gantry crane allows could cause an accident or damage the load or equipment.
Cable reels are a common choice for supplying power, as the spring-loaded or motor-driven design can release and retrieve cable as you need it. Mounting the cable reel on a swivel provides an ability to work in multiple directions, but the downside is that the cable will sag when long lengths are in use. This may cause problems for foot and motor traffic on the ground. Custom solutions may include a series of poles and beams designed to keep wires off the ground. For portable gantry cranes, a longer extension cord may be sufficient, or it may be possible to simply position the crane closer to a power source.
Common Applications & Uses of Gantry Cranes
Some indoor gantry crane models can lift up to five tons, making them useful in a range of applications such as shipyards, warehouses, manufacturing facilities, forges, and more. Gantry cranes offer versatility and reliability when lifting large and heavy components, raw materials, and heavy finished parts.
Gantry Crane Design Standards
Like other heavy equipment, gantry design is based on specific standards for function and safety. These standards cover design, fabrication, material selection, and even painting.
The Operational Safety and Health Administration (OSHA) offers guidelines for the safe operation of gantry cranes. The American Society of Mechanical Engineers (ASME) provides guidelines for building gantry cranes, as does the American Welding Association (AWS). All cranes must comply with these standards.
When you work with a reputable crane supplier, you can trust your gantry crane design meets all regulations to keep your workplace OSHA compliant and your employees safe. All gantry cranes manufactured or sold by American Crane follow the requirements set forth by these organizations. We also adhere to the stringent quality requirements and standards of the Crane Manufacturers Association of America (CMAA) in duty classes A through F. We factory test all of our gantry cranes before we ship to the customer.

President & COO
A hoist helps to raise and lower heavy loads and is sometimes used to transport objects from one location to another. There are many types of hoists that may be operated manually, pneumatically, or electronically. This mechanical device most often features one or multiple fixed pulleys, a moving pulley with a hook or other component for attaching loads, and a braided rope between them. As a leading manufacturer of hoists, American Crane can help you decide on the best crane hoist for your project’s needs.
Parts of a Hoist
There are many components that make up a hoist, including:
● Traveling Machinery. Made up of a motor, gear, and brake, the traveling machinery allows for the horizontal movement of the hoist.
● Trolley. A trolley is a support structure that the hoisting machinery is attached to. It is composed of a load beam and end carriages.
● Rope. The rope of a hoist features strong metal wires that are laid together like a helix or braid.
● Hook. The hook features a clamp that connects the load to the hoist. The clamp or other locking mechanism is necessary to support the object moved by the hoist.
● Controller. A radio or pendant operates the control system, which directs the vertical movement of the hook as well as the horizontal movement of the hoist.
How a Hoist Works
Operating a hoist includes knowing the weight restrictions and requirements as well as built-in safety features. The operator may set operating limits of a hoist, which limit movements under certain circumstances. A hoist also comes with safety features that prevent overloading a lift, limit travelling movement, or prevent all movements with an emergency stop button.
Once all regulations and requirements are set, the operator uses the controller to activate the relevant button or joystick to move the hook vertically. The signals given by the operator, along with any safety devices or sensors, control the break and motor. When the hoist receives the signal, power is supplied to the motor, releasing the break. The motor drives the hoisting gear, which reduces the rotation speed and increases torque in order to lift the load.
The rope is fixed to the hoisting drum on one end and connected to the rope anchorage on the other. As the hoist drum rotates, the rope winds or unwinds and is guided into the correct groove of the drum, allowing the hook to raise or lower. There are two ways to stop a hoist: by releasing the up or down controls on the controller, or by activating the emergency stop button.

Selecting the best crane or hoist equipment for your application is a challenging process. To find equipment that will facilitate safe and efficient operations, it is important to have a thorough understanding of crane terminology, different crane types, parts of a crane, and lifting terms. To help you, here is an overview of the top 12 terms you should know.
C.M.A.A. refers to the Crane Manufacturers Association of America, an independent trade association that establishes and maintains quality and performance standards for electric overhead cranes. Established in 1927 as Electric Overhead Crane Institution, the C.M.A.A. is an internationally recognized authority for crane standards.
One of the most noticeable crane components is the boom. While a crane boom encompasses a variety of designs and features, it is fundamentally defined as the framework that supports and moves the load.
Critical load refers to a load that requires additional control or support because it approaches the maximum weight capacity. If released or moved without adequate control, a critical load can severely compromise the safety of the system. Critical loads require the use of single failure proof cranes, which ensure adequate operational safety.
Explosion Proof Crane
Explosion proof cranes are specifically designed to contain explosions and prevent heat or sparks from entering the surrounding workspace. They are used for applications where flammable and explosive materials are present, and they are typically divided into Class I, II, and III.
Class I is the most stringent, and these cranes are intended for applications where ignition of highly combustible materials and gases is likely, while Class II cranes are for potentially combustible airborne dust. Class III is the least strict, and these cranes are for applications with potentially ignitable airborne fibers.
Flux Vector Drive
A flux vector drive is a variable frequency drive that is used to monitor and control the speed and direction of the crane’s motor shaft. It allows for a greater degree of control over crane speed and braking by using a closed-loop system and adjustable incremental encoder to monitor the motor shaft during operation.
The term “hoist” defines equipment that is used specifically for lifting and lowering loads. Hoisting, by its definition, is the act of raising a load on the vertical plane, and the term is often used in reference to the lifting applications of cranes.
For cranes, lift refers to the highest point to which a crane’s hook, magnet, or buck can lift a particular weight. Critical load calculations are used to define the lift of a given crane or hoist assembly, depending on the size and configuration of the crane and the weight of the load.
Load block is the assembly of crane accessories suspended by the hoisting lines, which includes the hook, swivel, bearings, sheaves, pins, and frame. It is used to lift and move the load, and it monitors the tensile pressure to ensure that the loads remain within lifting capacity.
An overhead crane is specifically designed to move heavy loads by operating from a fixed overhead structure. They can be operated using a mobile or stationary hoist and mobile bridge. Overhead cranes are available in a variety of designs and configurations.
Single Failure Proof
Single failure proof cranes are engineered to ensure that if one crane component fails, it will not cause the failure of another component within the system. This helps to secure the load, particularly in instances where load failure can have extremely negative effects.
Top Running Crane
Top running cranes are a type of overhead traveling crane that travels along rails supported by single or double girders with truck ends attached to runway support beams. They are capable of carrying loads without limiting capacity and are ideal for load-bearing applications in facilities with limited overhead space.
The wheelbase of a crane or hoist refers to the distance from center to center of the outermost wheels, measured parallel to the support rail. This measurement can be used to determine carrying capacity.

When it comes to overhead cranes, there are several options to choose from, including top-running and under-running. While top-running and under-running overhead cranes are both used to lift and move loads vertically and horizontally, each type offers their own unique advantages. Understanding the differences between these two types of cranes will help you determine which one is best for your needs.
Top-Running Overhead Cranes
Top-running overhead cranes run on a fixed rail mounted on top of each runway beam, which allows the end trucks to carry the girder and hoist along the top. These cranes can be set up as a single girder or double girder depending on the application needs. A single girder has a trolley and hoist mounted on the bottom, whereas a double girder uses a top running trolley and hoist, allowing for additional lift height and a higher hook height.
Some key advantages of top-running overhead cranes include:
- No limiting capacity. This allows for the ability to handle both small and large loads.
- Added lift height. Being mounted on top of each runway beam allows for increased lift height, which is beneficial to buildings with limited headroom.
- Built for higher capacities. Top-running overhead cranes are built larger than under-running cranes to grant them the ability to handle higher capacities.
- Easy installation. Since the crane is supported by the runway beams, it eliminates the suspended load factor to make installation simple.
- Less maintenance. Over time, top-running overhead cranes do not require as much maintenance other than the routine checking of the tracking for proper alignment and any issues.
Under-Running Overhead Cranes
Designed with flexibility and functionality in mind, under-running overhead cranes have a user-friendly design that provides ultimate versatility for meeting all your production needs. These cranes are also known as underhung cranes because the bottom flange of the runway beam offers support for the wheels to move the bridge across the facility.
The trolley and hoist of an under-running overhead crane move across the bottom flange of the bridge beam, lowering the crane’s hook and lift height. Under-running overhead cranes are usually set up as single girder because a double girder design is often more expensive and not suitable for the application.
Some advantages of under-running overhead cranes include:
- Operates well in wide bays. Underhung cranes can be operated in multiple runways, reducing the depth of the girder.
- Lighter overall design requirements. Under-running overhead cranes are much lighter, which removes the need for additional supporting columns that take up precious floor space. Instead, the crane utilizes the existing overhead building structure for support.
- Lower costs. The lightweight design and use of the existing ceiling trusses or roof structure result in lower equipment costs.
- Ability for multiple crane installations. It is possible to install under-running cranes next to each other and operate them at the same time for increased production efficiency.

There are many facets to crane operation safety, and you can’t afford to ignore any of them. To avoid employee injuries, OSHA fines and lawsuits, and the cost of repairing equipment and property, it is crucial to make the following safety considerations: have a certified and competent crane operator, perform regular inspections of the crane and job sight, abide by load capacities and weight requirements, use equipment properly, and communicate effectively.
To take a well-rounded approach to crane operation safety, it is important to consider these five safety tips:
- Have a certified and competent crane operator. Having a fully trained crane operator is the most important safety consideration. Without a qualified operator, it won’t matter how well you address other safety considerations.
- Perform regular inspections of the crane and job site. It is important to inspect the crane, rigging, and personal safety gear for wear, damage, and functionality. You should also inspect the job site by making sure that the crane is on a stable surface and that there are no obstacles in the swing radius or below the crane. Work environments change frequently, so performing these inspections regularly is crucial.
- Abide by load capacities and weight requirements. All hardware, ropes, and slings have particular weight restrictions, and it is crucial not to exceed them. Overloading your equipment could cause the crane to tip or the load to drop, crushing anything beneath it. Overloading equipment can also lead to costly equipment damage.
- Use equipment properly. Cranes are for vertical lifting, not for dragging or side loading. Using cranes for improper activities puts stress on the turntable, the boom, and the structural members, potentially weakening components and causing equipment failure.
- Communicate effectively. Use hand signals, radios, or air horns to ensure clear communication between the crane operator and other workers. It is important to make sure that each employee knows what the signals mean to eliminate safety risks and confusion.

There is no one-size-fits-all crane solution. Overhead cranes are as versatile and varied as the jobs they’re built to do, with each crane type designed for specific types of work. For safety, effectiveness, and efficiency, it’s essential to get the right overhead crane for your project. Read on to learn more about types of overhead cranes and how to choose the best one for you.
What Will Be the Overhead Crane’s Purpose?
The first step in determining which overhead crane you need requires understanding the types of lifts you need the crane to do and the environment in which it will operate. Some of the questions you should ask include:
- What size is the facility?
- How heavy are the items the overhead crane will be lifting?
- How many loads must it lift per hour, and how many hours per day will it be in operation?
- What range of movement does the crane need?
- What’s the temperature of the facility? Will there be sizeable temperature changes?
- Will the crane need to tolerate exposure to certain chemicals, gases, moisture, sunlight, rain, wind, dust, or other potentially harmful factors?
- Will the crane work with explosive or corrosive materials?
- Will the lifts require rapid, repeatable lifting or slow, precise crane handling?
Determining these factors will help you to identify the overhead crane best-suited to your application and environment.
The Overhead Crane’s Weight Capacity
Cranes have varying capabilities when it comes to lifting. Each machine has a maximum lifting capacity, which is the heaviest weight that the crane can lift safely. Determining the maximum safe lifting capacity isn’t always as simple as knowing the weight of the lifted items.
For example, say you need to lift a product that weighs five tons. Whether a crane with a five-ton capacity will best suit the job depends on multiple factors. The answers to these questions will help you determine if a five-ton maximum lift capacity is enough:
- How many times a day must the crane lift that five-ton weight?
- Does every item weigh five tons, or do most of them weigh far less?
- Will the crane occasionally need to lift something heavier than five tons?
- Will operational changes or expansions require heavier lifts in the future?
You might want a slightly higher lifting capacity than your maximum lift to stay on the safe side, but there’s also no reason to go too big. Overhead cranes tend to become more expensive as lifting capacity goes up, so going overboard on maximum lift capabilities will ultimately cost unnecessary money. Conversely, barely scraping by on lifting power and overworking the machine will result in expensive repairs or replacements, ultimately driving up costs in the long run.
You also have to consider the crane’s speed requirements and how the load’s weight will affect it. While standard speeds are sufficient for most applications, yours may have unique needs. Maintaining your production output could rely on a crane that can move quickly, with easy loading and unloading. Assembling products may require slower-moving, highly precise crane operation.
Each type of overhead crane has its benefits, and most are customizable to meet specific needs. When trying to determine the best crane for your needs, this general breakdown may help:
- Overhead bridge cranes have the largest lifting capacity.
- Double-girder bridge cranes work at high speeds and repeatedly lift heavy loads
- Overhead gantry cranes offer precision movement
