Jibs – manual rotation or powered rotation Jib capacity capabilities range from a few hundred pounds to a project completed with a pillar double girder 15 ton Jib.
Girders are large beams used in heavy constructions, such as bridges, buildings, and tunnels. However, because they are a special type of beam that provides horizontal support and can bear both dynamic and static loads, they also can be used in heavy-duty lifting equipment such as girder cranes.
While both single girder and double girder cranes are strong and durable, they offer different lift and height capabilities. On single girder cranes, the hoist hook is attached below the girder with the assembly attached to the underside, which removes a potential 18 to 36 in. from its vertical lifting capacity. But in double girder cranes, the hoist is in the same plane as the girders and the hoist assembly is attached along the top of the girders, resulting in higher lift capabilities of taller loads.
Double girder cranes also are preferred for very heavy duty and severe duty, or D+ and E rated, respectively, lifting duties. This isn’t because double girder cranes have more power or duty classification. Instead, it’s because the double girder cranes tend to have more specialized equipment. Double girder cranes more practically incorporate a service platform for technicians to use as well.
Our top running double girder cranes come in different lifting classes so you can choose the right equipment for your project’s needs. Choose between 3-ton, 5-ton, 7.5-ton, and other capacities up to 20 tons. These cranes also have fixed axle wheels.
We can design and manufacture cranes that fit your unique project needs, including carrying capacities of up to 1,000 tons. Our team creates custom engineered lifting equipment and components that can handle extreme industrial needs. For example, our custom cranes are employed for aerospace applications, in operations at military sites, and at nuclear fuel facilities. Our custom cranes can be built with multiple girders and be designed for heavy-duty lifting needs under CMAA Classes A-F.
Girder cranes have reliable heavy-duty lifting capacity and offer excellent performance at construction sites, mining sites, and industrial facilities. American Crane is the go-to industry expert for safe, reliable lifting equipment. We can design and craft custom cranes for specialized worksites, and we have an array of standard options.

Both overhead cranes and hoists are machines used to move heavy or bulky materials and equipment around industrial and commercial job sites. While some people incorrectly use the terms interchangeably due to their similarities in function, they remain distinct machines due to their many differences in design and use. For example, hoists move loads up and down, while cranes move loads up and down and side to side.
Below, we provide a more comprehensive overview of overhead cranes and hoists, discussing what they are, how they operate, and how the two types of lifting equipment differ.
The hoist:This part controls the vertical lifting and lowering. It is fixed to the trolley component, which allows it to move back and forth across the bridge as needed. Its load capacity depends on its design and construction. For example, chain hoists are suitable for loads of 5 tons and below, while wire rope hoists are suitable for loads of 5 tons and above.
The trolley:This part moves the hoist along the bridge. It is available in three main types, each of which offers different advantages in different applications. Low headroom trolleys feature a compact design that makes them suitable for single-girder crane applications, normal headroom trolleys are suitable for monorail and jib crane applications, and double-girder trolleys provide superior clearance and headroom for double girder-crane applications.
Gantry cranes: In gantry cranes, the bridge component is not attached to the ceiling. Instead, a single or double girder is attached to wheeled legs. This crane design is popular in shipbuilding applications.
Monorail cranes: In monorail cranes, the trolley-mounted hoist moves along a single, circular, oval, or winding path throughout the facility. This crane design is suitable for moving loads within tight or complex spaces.
Despite their limited directional mobility, hoists are still commonly used as lifting equipment for various heavy materials and equipment. The type employed varies from application to application, depending on the lifting requirements. Some of the design factors to consider include:
Power:The power refers to how the hoist is powered. It can be a manual mechanism (e.g., a pulley used to multiply the pulling force input by the operator), an electrical mechanism (e.g., an electrical motor), or a pneumatic mechanism (e.g., an air-powered motor). The type used in a hoist system depends on the lifting/lowering force required and the existing setup of the facility. For example, facilities that already use air tools may find pneumatically powered hoists easier to integrate.
Suspension:The suspension refers to the mounting method of the hoist. Some of the most common are hook-mounted, lug-mounted, and trolley-mounted. The type used in a hoist system depends on the lifting requirements. For example, hook-mounted hoists are used for lifting applications that only require moving the load up and down, while trolley-mounted hoists are used for lifting applications that require moving the load up and down and to different areas of a worksite.
There are many differences between overhead cranes and hoists. The main one is their range of movement. Hoists can only move loads up and down, while cranes can move loads up and down and side to side. In the latter, a hoist serves as the component that provides vertical movement, while a trolley and bridge serve as the components that enable horizontal movement.
The other main difference between overhead cranes and hoists is how they are categorized. Overhead cranes are generally grouped by their design and construction (e.g., top running, under running, gantry, and monorail), while hoists are typically classified by their lifting medium, power type, and suspension.
While overhead cranes and hoists differ in design and purpose, both pieces of equipment are valuable tools in moving heavy and bulky loads in industrial and commercial worksites. However, it is essential to choose one that is well-suited for your application. If you need help selecting and sourcing overhead cranes or hoists for your facility, ACECO is your expert, craftsman, and partner.
