What's the main specifications of overhead cranes? Overhead crane specifications can provide information about crane capacity and dimensions and lifting applications. An industrial overhead crane is a permanent material handling system that is built into a manufacturing space or warehouse and is made up of a bridge beam, runways, a trolley traveling lifting mechanism, an electric mechanism, and other crane parts. We adhere strictly to national standards and have standard engineering specifications. If you need an overhead crane with tailored specifications, our company can provide you with clear, concise, and accurate crane system information for procurement.

Terms on crane specification confirmations

Overhead Crane Capacity

What is the definition of overhead crane capacity? The maximum weight that an overhead crane is designed to lift is defined as its capacity. A crane's rated capacity is typically displayed on both the hook block and main girder of crane bridge.

Overhead Crane Span

What exactly is an overhead crane's span? Overhead cranes typically travel on rails attached to a runway system. The span or horizontal distance between the rails, or more accuratly the distance from the rail center to rail center , which is defined as the overhead crane span.

Hook Height or Height of Lift

When the crane hook is in its highest position, the hook height or hook patch refers to the distance from the crane hook to the floor. What is critical is the lifting height determines how high the runway must be from the ground and it is directly related to the building's or structure's clear interior height.

Lift, Trolley, and Bridge Speeds

These speeds are generally presented in FPM (feet per minute) and shows the rate at which the bridge, trolley, and hook move. The speeds can be pre-set to one or two speeds (high and low). A VFD (variable frequency drive) which allows for speed customization while also creating a soft start and stop, is another popular and effective option for controlling the motions of overhead crane.

Crane Lift Speed

Crane lift speed is the rate at which the bridge or trolley moves or the hoist lifts, usually measured in feet per minute or FPM. With a Variable Frequency Drive, the crane lift speed can be adjusted (VFD). This also allows you to overspeed the hoist to reduce cycle times when the host is lightly loaded.

Single Girder Overhead Crane Specifications for Your Selection

Top Running Single Girder Bridge Crane

The most common type of overhead crane is the top running single girder overhead crane. It is a multi-purpose bridge crane that can be used in a variety of industries. Top running single girder overhead cranes with capacities up to 15 tons and spans up to 98 feet can be built. Top running single girder overhead crane capacities typically range between 5 and 10 tons and customized design can be 20 ton and 32 ton.

The bridge beam is typically a wide flange structural member with capacities less than 10 ton. A box girder bridge beam will typically be used by cranes with spans greater than 60 feet and capacities greater than 10 tons.

The hoist/trolley used on a top running single girder overhead crane is always an under hung trolley that runs on the bridge beam's bottom flange. As a result, a top-running single-girder overhead crane is always prefered to workshops with adequte headroom space.

Under Hung Single Girder Bridge Crane

The most typical overhead crane for low lifting capacities is an underhung single girder overhead crane, also known as an underrunning crane. These cranes are most popular in high production rate facilities and assembly plants because they are one of the most cost-effective styles of overhead cranes. Under hung single girder overhead cranes with capacities up to 10 tons and spans up to 60 feet can be built. Underhung single girder cranes, like top running single girder cranes, use a wide flange structural bridge beam and an underhung style trolley that runs on the bottom flange of the bridge beam.

Under Hung Single Girder Overhead Cranes run on the bottom flange of a structural or patented track runway beam. As a result, underhung single girder cranes typically require a significant amount of headroom in the customer's facility. More headroom can be achieved by modifying the beam to end truck connection, but the hoist/trolley end approach may be compromised.
