Getting To Know The Top Running Overhead Crane Options
In relation to buying an overhead crane, one of the primary questions folks have is frequently whether an under running or top running overhead crane system is the best option for operations. There are overhead crane systems in also types of different configurations available, but deciding if they should select a top running or under running design is actually a key decision. Some of the questions you have to answer to determine which overhead crane system might be best include:
• Will the existing support structure on your facility be utilized or will a brand new support structure have to be constructed?
• Just what is the maximum capacity of loads your business handles?
• Does your facility have existing runways that could be repurposed for any new crane system installation?
• How much overhead room do you possess available? Is headroom limited due to light fixtures, water pipes, ductwork, existing cranes, etc.?
• How high your choice need to lift loads?
• Is apparent floor space essential for some operations in your facility?
Now let's discuss a number of the features and advantages of top running overhead cranes. Such cranes require installing a fixed track or rail system on each runway beam. The cranes might 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 just not limited and they can be manufactured to lift small capacity and additional-large capacity loads from 250kg to 250 tons. Considering that the cranes are backed by steel support columns or existing concrete steel building support structures, there are good for moving very heavy loads.
A high running overhead crane by using a double girder bridge design ensures the utmost 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 typically larger than their under running counterparts, they can accommodate higher load capacities and wider spans. Repair of overhead top running crane setups can also be easier like a suspended load factor lacks to be taking into account.
Options That Come With an individual Girder Top Running Overhead Crane
• Support for load capacities starting 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
