Overhead Cranes
Overhead Cranes
Move any load, big or small, with ease and precision
Overhead Bridge Cranes are typical for heavy-duty material handling applications. The crane capacity, bridge span, and hook height, among other factors, determine whether you use a top-running single girder or double girder crane, or an under-running, single girder or double girder crane.
Our teams work together under one roof to provide you with a standard, modified, or custom-engineered crane system that ensures you achieve your material handling needs. We will work with you to determine the most suitable bridge crane to match your requirements.
We design our cranes to meet and exceed CMAA (Crane Manufacturers Association of America) specifications.
Top Running Overhead Cranes
Designed for Your Requirements
Designed specifically for your application, top running overhead cranes or bridge cranes are the most effective lifting solution as you have the best coverage within your facility. Offered in both single, double and box girder designs, there are enough options to suit your application.
Top running overhead bridge cranes are designed to travel on top of a runway system that is either supported by engineered columns or building columns.
Double girder designs typically provide you a better hook height than single girder designs as the hoist is mounted on top of the bridge rather than underneath.
Our overhead cranes are the benchmark in the industry as we build them to sustain multiple work environments.
Top Running Overhead Cranes come in two options:
Single Girder Top Running Overhead Crane
Providing you excellent value for your application, single girder designs allow you to be cost effective without compromising performance. Over the lifetime of the crane, you will save on new support structures as it has reduced wheel loads. This allows you to add more lifting capabilities to your runway structure without upgrading.
Double Girder Top Running Overhead Crane
Designed for applications with load capacities typically over 25 tons, double girder cranes are used when you need a complete lifting solution. Double girder cranes give a better height of lift compared to a single girder crane as the hook travels between the beams.
Under Running Overhead Cranes
Ideal for Low headroom Applications
Under running overhead cranes or bridge cranes are an ideal solution when headroom is limited. The crane travels underneath the runway structure, which allows you to maximize the distance from the ground to the hook. Typically, an under running overhead crane is supported by the building structure in order to maximize the height inside of the building. Offered in both single, double and box girder designs, there are enough options to suit your application.
Double and box girder designs typically provide you a better hook height than single girder designs as the hoist is mounted on top of the bridge rather than underneath.
Our overhead cranes are the benchmark in the industry as we build them to sustain multiple work environments.
Under Running Overhead Cranes come in two options:
Single Girder Under Running Overhead Cranes
Providing you excellent value for your application, single girder designs allow you to be cost effective without compromising performance. Over the lifetime of the crane, you will save on new support structures as it has reduced wheel loads. This allows you to add more lifting capabilities to your runway structure without upgrading.
Double Girder Under Running Overhead Crane
Designed for applications with load capacities typically over 25 tons, double girder cranes are used when you need a complete lifting solution. Double girder cranes give a better height of lift compared to a single girder crane as the hook travels between the beams.
Custom Overhead Cranes
Designed and Engineered for You
Some industrial processes with complex or unusual requirements require a custom designed overhead crane specifically for that application. Standard solutions don’t always work when high rates of handling integration or unusual combinations of crane speeds and duty ratings are required.
In situations where there are unique safety considerations, space restrictions or lifting methods, O’Brien welcomes the challenge responding with custom overhead crane systems that fit your unique requirements.
Monorails
Monorails: Simple Lifting with One Beam
Monorails overhead systems are a simple lifting device with one stationary beam that has a hoist and trolley. With its lightweight design, it can deliver materials from one specific location to another at relatively quick speeds.
Our highly skilled engineering staff can customize your monorail with curved tracks, multiple switches, and interlocks.
Our monorail system comes in two designs, ceiling and floor mounted.
Features:
- Capacities up to 20,000 lbs
- Runway supports up to 30 ft
- Curved section tracks available
- Low cost
- Free standing and ceiling mounted designs
Runway Structures
Runway Structures: Strong Supports for Your Crane System
Runway cranes are subject to vertical stress, horizontal stress, impact loads, pulling and lifting actions and thermal expansion. Runway rails slip, girders deflect and rotate, and columns deform. Of all structural elements in a plant building, crane runways are among the most susceptible to failure.
O’Brien specializes in crane runway structure design and installation. With over 60 years of experience, our professionals understand the dynamics of a rigid system that must withstand a great deal of movement and flexibility.
Runway problems can be avoided. O’Brien specialists build, re-build, install and repair crane runway systems that save customers from difficult, expensive and dangerous runway breakdowns.
Lifting Beams
Complete Lifting Stabilization
Our lifting beams or spreader beams are designed for applications where there are multiple pick points. The lifting beam is attached to your existing crane by the hook to provide you more stability.
Features
- Swivel hooks with hook latches
- Fixed or adjustable hook positions
- Designed and manufactured to ASME B30.20
- Safety yellow oil base paint finish
Configurations
- Coil lifting beams
- Magnet beams
