Why To Consider The Mixed-Capacity Bridge Cranes On A Single Runway?

Mixed-Capacity Bridge Cranes are a candid solution for organizations aspiring to leverage their System capacity and cut down the Bridge Dead Weight. It is because using various small bridges with Heavier Runways helps in accommodating various Lifting Solutions within a single coverage area. 

An Overview of the Mixed Capacity Bridge Cranes 

Installing various multi-capacity bridge cranes along the same runway helps in extending the coverage area. Besides, it enhances the production capacity of the application of a complete system. These systems allow the use of multiple bridge cranes on one runway. Most importantly, it helps enhance the system's flexibility by cutting down the heavy Bridge Dead Weight. It permits workers to use multiple applications to lift and shift loads without loading the system beyond its capacity. These bridge cranes feature lesser weight compared with the single heavy bridge crane system. It makes the unit extremely flexible and highly portable. 

It is crucial to note that the summation of the individual crane capacities should not exceed the runways' total accommodation capacity. The capacity of the Runways is equal to the live load that the system can lift. The Bridge Crane at the Workstationgets gets designed with 15% of the hoist and the trolley weight. It implies that a thousand-kilogram bridge crane can accommodate up to eleven hundred and fifty kilograms, combining the trolley and the hoist's weight. If you are overloading the system, you are staking your workers to injuries and accidents. On the wrong side, it can even result in severe casualties. Therefore, you must seek appropriate guidance and advice while installing the system. 

Handling Mixed-Capacity Bridge Cranes with foolproof safety measures 

In case you are planning to install various Mixed-Capacity Bridge cranes on a single runway, you require to consider a few crucial points. In the first instance, you should focus on expanding the runway length to the maximum capacity possible. It will enable the system to cover the length of the entire facility. However, keeping the span minimum is not at all a bad proposition. It ensures that the system gets the optimum ergonomic design. 

As a thumb rule in this context, the lesser dead weight allows the operator to manoeuvre better. It is for this reason that a shorter bridge span comes ideally suitable for more extensive production facilities. Likewise, for limited production areas, a shorter bridge span is ideally suitable. The majority of engineers will endorse low capacity systems to optimize production. Remember, when you enhance the capacity beyond a reasonable extent, you get into an excessive dead weight that significantly reduces efficiency. 

What are all other options you may consider?

Even if a single runway is potent to handle various mixed-capacity bridges, still you have various other options to consider. It depends on your needs and the type of facility and operation. Intermediate Terminals, Bridge Buffers and Anti Collision are the most relevant options to consider. 

Bridge Buffers

A usual Mixed-Capacity System is a worthy option to consider. Mixed-Capacity Bridges runs for the full length of the runway. However, you are spared the threat of overloading it. It implies you need a runway featuring appropriate lengths for supporting all the active bridges. As the cost factor is a crucial area of consideration, the bridge buffer system ensures perfect utilization without overloading the system. It involves a lesser cost than the cost involved with the mixed capacity applications

Employing a Bridge Buffer system, the size of a bridge is directly proportional to individual load. The size of runways gets adjusted to harvest the individual load. It implies the runway will be utilizing the same track as the largest bridge. It is entirely different from the mixed-capacity systems as the runway capacity does not impact the most massive bridge. It paves the way for installing a single runway across the entire system, enhancing flexibility and overall productivity. You can consider investing in one massive bridge as it will differentiate between the bridges. 

Bridge Buffers come suspended from double trolleys on the same runway. It creates the minimum distance for the bridges to operate. The design focuses on rolling the bridge to escape the overloading of the system. The bridge buffers ensure that the system never gets overloaded. It retains the minimum space between two bridges, especially when the system is under load. 

Bridge Buffers are candid solutions to downsize the operating cost and enhance system flexibility. However, it comes with its downside. As the mechanism utilizes space, it creates a dead zone between the bridges. It eventually restricts the scope of coverage. Anti- Collision is a new concept being used instead of bridge buffers.

Intermediate End Stops 

This system serves the same purpose as the Bridge Buffers, though subtle differences exist in their designs. It focuses on handling the individual load. On the other hand, the runway handles the most massive individual load. These bridges feature separation by bumpers or internal stops. Its best part is that it will considerably develop the minimum dead spots, enhancing the flexibility and efficiency of the system. However, it always restricts the extent to which the bridges can travel while under load. Thus, you have good reasons to invest in Intermediate End Stops.
