Heavy duty gantry crane is kind of lifting crane with large lifting tons. Compared with small gantry crane, heavy lift crane can lift more material at one time, and it has higher working class. Heavy lift cranes are widely used for loading, unloading and transporting material in construction site, station, open storage yard, industrial and mining enterprise, and materials department. Ellsen Group, a professional gantry crane manufacturer, has much cranes business experience, supplies types of cranes with reasonable design, top quality, perfect performance and affordable price.
How to operate heavy lift cranes safely?
Heavy duty gantry crane lifts more material than light duty crane, which means if not operating properly, it is easy to have problems with crane safety. Thus it is important to know how to operate heavy lift crane in correct way.
Before starting gantry crane, carefully check all gantry crane parts are in normal state. In this way, it can reduce failure rate. During work, pay attention to operation rules and strictly obey the requirement. Correct operation ways can ensure operator security and decrease damage to the crane.
Learning more about the safety devices for a heavy duty crane
Workplace safety is of the utmost importance, especially if you work with industrial machinery. People are injured in machinery accidents every year. Thankfully, manufacturers are working to introduce new features that can help keep workers safe.
Take a look at some of the most popular safety devices for heavy duty cranes. When you look at the precautions major companies are taking, you will see how safe modern machinery can be.
A number of accidents occur because one component of a machine doesn’t work the way it is supposed. If one process fails, it can start a chain reaction that causes a host of other problems.
As an example, brakes have caused a number of issues. In older machines, brakes can usually only be used by the person operated the device. If those brakes don’t work, or if the operator becomes incapacitated, it could lead to a serious injury.
Now, newer machines have fail-safe brakes. In many cases, these brakes can be engaged remotely. If the operator can’t use brakes to stop a crane, someone else can use the brakes instead. The machine will come to a stop, and an accident will be avoided.
Controlling a crane can be difficult, especially when you’re carrying a large or heavy load. However, manufacturers have worked to make cranes easier to control. They’ve introduced semi-automated controls. While the operator still has control over when and where the crane moves, the controls can help to keep the machine steady.
A number of accidents are caused because a crane comes into contact with something it shouldn’t, such as a power source. When you have semi-automatic controls, these issues are easy to avoid. The crane can automatically detect if it is about to collide with something, and can slow or stop as a precaution.
Even a well-trained operator can make mistakes. With a safety feature like this, those small mistakes won’t turn into a major issue. You can avoid accidents and continue to complete your work.
When a crane is carrying a heavy load, it may not move steadily. A crane’s weight limit isn’t always the amount it can comfortably carry; instead, it’s the maximum amount of weight it can manage. Because of this, heavier loads can be extremely difficult to maneuver.
Thankfully, new safety features make it easier for a crane to stay steady. In addition, manufacturers are working make sure that a crane moves smoothly even when the load it’s carrying is quite safely. With the right crane, you’ll be able to transport heavier loads with ease.
Today’s heavy duty cranes are much safer than the product that were used in the past. They contain a number of safety features that make the machine easier for operators to use.
If you want to improve safety in your workplace, take a look at some of the features that are currently available. Decide whether or not you would like to update your current machinery.
What is a heavy duty gantry crane typically used for?
When a company is installing a gantry crane, they are typically doing so to move exceptionally large products. Going down to the local peer, you will probably see enormous ships that are situated underneath a full gantry crane, or a container crane, that is specifically designed to pick up the merchandise, and distributed onto the dock. The same is true for when the ships are being loaded, and these cranes can handle a sizable amount of weight. It is not uncommon for these cranes to handle 100 tons or more, with some of them, especially the full gantry cranes, capable of handling upwards of 1000 tons. These are what are referred to as heavy-duty gantry cranes, and let’s present a little bit of information about how they are used and what they are able to do.
Container and full gantry cranes
This type of gantry crane is also called a ship to shore rail mounted crane. It works by using a hoist that will lift the containers often the ship, and they will be moved courtesy of a trolley system that goes along the trolley frame attached to the overhead girder. This can be a very efficient system for loading and unloading cargo. Heavy-duty cranes are either made in a box shaped format, or they will come with a trust structure, which will give them both advantages and disadvantages.
Advantages and disadvantages of heavy-duty gantry cranes
The main advantage to using these cranes is that they are exceptionally powerful. The average weight that they can handle is roughly 100 tons. The lifting height is typically right around 35 m, and they are powered by a diesel generator, or a cable reel which allows it to lift and lower the merchandise. One of the benefits of the box shaped crane is that it uses steel plates that are welded together to provide exceptional strength. This design, however, has a large problem with wind resistance, plus it can be very expensive. On the other hand, the trust structure has excellent wind resistance capabilities, perfect for docks that are known for having an exceptional amount of wind. The disadvantage is that a trust crane has a much lower lifting capacity, and it also uses a solder joint which is difficult to maintain.
Saving money on your next heavy duty gantry crane
One of the benefits of living in this age with Internet access is that you can see what countries are selling all over the world. Websites have been put up by some of the top gantry crane producers, and you can see what some of their latest models are. It doesn’t matter if you are looking for a rail mounted gantry crane, or a cantilever crane instead. If your main focus is to find a heavy-duty gantry crane, you can get a free quote from most of these reputable companies that will be more than happy to not only tell you how much it will cost, but give you an estimate as to when it will arrive at your facility.
If you are actually looking for a heavy-duty gantry crane, you are likely in an industry where a large volume of extremely heavy containers are being moved regularly. Just make sure that you choose one that is going to be the most beneficial for your business, whether this is a truss or box shaped heavy-duty crane.
What are security devices of heavy lift crane?
For heavy lift crane used outdoor, reasonable safety protection devices are very important. Security device can protect operator and prolong the service life of gantry crane.
In order to prevent tilting and crane glide, anchor and rail clamping device are fixed. The anchor has three types, anchor pile type, balance weight method, anchor pit type. General gantry cranes mainly use anchor pit type. It can ensure the crane travelling stable in the strong wind. Rail clamping device is usually used together with anchor so that it has more powerful capacity of anti-wind.
To use machine safely, the crane is equipped with wind speed alarm device. If the crane is used at the seaside, it can sent warn when encountering the typhoon.
The trolley and crane mechanism are both equipped with buffer and limit switch. And crane stopper and safety ruler are set at the end of the girder.
