Learning The Top Running Overhead Crane Options

 When it comes to buying an overhead crane, one of the many questions individuals have is usually whether an under running or top running overhead crane system would be the best choice for operations. There are overhead crane systems in also types of different configurations available, but deciding if they should choose a top running or under running design is really a key decision. Some of the questions you must answer to determine which overhead crane system would be best include:

• Will the present support structure on your facility be applied or will a fresh support structure need to be constructed?

• Just what is the maximum capacity of loads your organization deals with?

• Does your facility possess existing runways which can be repurposed for any new crane system installation?

• Exactly how much overhead room do you have available? Is headroom limited due to lighting fixtures, water pipes, ductwork, existing cranes, etc.?

• How high up to you need to lift loads?

• Is clear floor area required for some operations in your facility?

Now let's discuss some of the features and benefits of top running overhead cranes. Such cranes require setting up a set track or rail system on each runway beam. The cranes may be configured into double girder bridge or single girder bridge designs. A double girder design adopts top running trolley and hoists, while single girder bridge designs use underhung trollies and hoists.

The lifting capacity of top running overhead cranes is not really limited and they could be built to lift small capacity and further-large capacity loads from 250kg to 250 tons. Since the cranes are backed up by steel support columns or existing concrete steel building support structures, there are good for moving very heavy loads.

A top-notch running overhead crane by using a double girder bridge design ensures the maximum possible lifting height inside a building considering that the hoist and trolley travel along the top of the the girders. This may result in an extra 7 feet of lifting height. As a result, such cranes are best for buildings with limited headroom.

While top running overhead crane setups are usually bigger than their under running counterparts, they are able to accommodate higher load capacities and wider spans. Upkeep of overhead top running crane setups is likewise easier as a suspended load factor lacks to get taking into consideration.

Features Of a Single Girder Top Running Overhead Crane

• Support for load capacities ranging from 250kg to 20 tons.

• Light duty servicing.

• A normal span width of under 65 feet.

• Increased overhead space.

• Cheaper production costs.

• Low deadweight.

• Ideal applications: light assembly line, light manufacturing, fabrication shops, warehousing facilities, and machine repair centers.

Features Of a Double Bridge Top Running Overhead Crane

• Support for load capacities starting from 20 tons to in excess of 400 tons.

• An average span of over 65 feet.

• High-speed.

• Maximum overhead space.

• Maximum lifting heights and hook length.

• Common applications: large-scale tool facilities, casting plants, large fabrication facilities, paper mills, coil handling foundries, and metal mills.
