Workers in the civil engineering and manufacturing field may need to lift heavy materials and move them to a different site. Without the right steps, you can find the risk of workplace injuries. To ensure safety, increase productivity, and streamline the overall process, you can invest in cranes to manage materials. Although there are cranes of different types and models, we are going to talk about Jib cranes. In some situations, when forklifts are not the right choice, you need to use Jib cranes. Truly, a Jib crane is a versatile system giving your protracted and lateral material handling options.
Design Concept of a Jib Crane
You may need to move your load in a multidirectional or unidirectional at the outdoor/ indoor sites. For both these purposes, you can rely on Jib cranes. As one of the overhead lifting systems, the Jib crane comprises a mobile hoist (usually a chain hoist), fitted to a horizontal part known as a Jib. You can attach this Jib to another vertical staff (mast), while you need mobility to your crane.
The hoist helps in lifting and lowering a load by using either a drum that includes wire rope wrapped around it or a chain sheave that has load chain passing over it. Some users keep the mast stable on the ground. With Jib cranes, you may lift your loads laterally or to any direction covered by the arc (made by a boom). However, standard Jib cranes have the capacity ranging from 250 lbs to 15 tons. The best models always have an ergonomic design, preferable to most of the users. You can raise the productivity level of your workers by investing in these Jib cranes.
A Jib crane is useful not only in construction fields but also in military ships and. In most cases, you can find floor-mounted models with self-supported systems. Jib cranes play an important role in lifting purposes. By releasing the overhead crane, they simplify the work. These floor-mounted cranes are applicable for sharing the load of the major crane. You can rotate these manually-operated cranes almost 360 degrees. Another option for you is the wall-mounted crane horizontally mounted on your walls. However, it has no vertical shaft, and instead, there is an RCC column bracket. One of the similarities between these two types of Jib cranes is the hoist mechanism. You can rotate wall-mounted cranes up to 200 degrees.
Do you know that Terex CTL 1600 tower crane is one of the biggest Jib cranes in this world? Its height can reach almost 89 m, while the length of its Jib arm is about 75 m. The load lifting capacity of this Jib crane is 65 tonnes.
A Comprehensive Guide To Buying The Best Jib Crane
Jib cranes are one of the reliable load lifting systems used for lifting relatively smaller loads around a point or a machine. The major reason to select them is the reason for operating them in a confined space.
However, choosing the best jib crane is the most important step to make a deal. Based on the type of operation, costs, ease of installation, and your facility layout, you can find the right jib crane.
- Height: The term, height, indicates two things- one of them is height under the boom and the other one is the distance up to the highest point of the crane. You have to measure the height from the floor surface to the base of the boom. This distance will let you find the right hoist. Now, after installation, the crane attains a height, and you need to know it. You must focus on electrical entry and other attachments to prevent any obstruction.
- Jib room rotation and outreach: Pillar-type (freestanding) jib cranes ensure rotation by 360 degrees. However, for wall-mounted ones, it is about 180 degrees. Moreover, the boom outreach is another factor to buyers. Boom span indicates the distance up to the tip of the boom. The hook reach denotes to the gap up to the farthest spot of the lifting load.
- Capacity: It indicates how much weight a jib arm can carry at its tip. The highest load on this arm must not cross the stated capacity. Impact, trolley weight, crane capacity, and hoist weight- these four things constitute the design capacity. At LOADMATE, we help you to know the design criteria based on your needs. You will find the crane performing at the best level.
- Source of power: A Jib Crane can rotate its system manually or with power. Power rotation is helpful for controlling bigger loads. It also keeps the operator safe. Manual systems can deal with lighter loads. Motor-driven trolleys with electric chain hoists are the right choice that you can use with your jib cranes. To get power for your cranes, there is a special floor-mounted, lockable disconnect.
- Working span: It is another measurement of distance indicating how much the hook can move to reach another end of the jib arm. The jib arm length maybe longer, compared to that of the working span and trolley length.
- Installation: Ease of installation is a vital factor for buying jib cranes. Freestanding jib cranes need a concrete base for proper installation. However, you can install wall-mounted ones against steel columns, including flange beam, hollow tubing and monolithic columns.
- Weatherization: In some cases, the crane and its components need proper weatherization to make them ready for outdoor application.
- Check for clearances and dimensions: The hoist beam has to be high to clear the system underneath it. The hook height has to be adequate to lift loads and place them. After establishing the height, you have to make sure that the boom’s top portion clears the obstruction.
How to pick the best Jib Crane
Now, we will help you with a Jib crane buying guide to let you find the right one for your purpose.
- Ease of installation and maintenance: Cost is one of the major factors to a Jib crane buyer. However, most of us focus only on the price of the device. You must also know the installation cost for the Jib cranes. In addition, you have to ensure that your chosen crane has the proper dimensions. What’s more, you have to find out the cost of maintaining the performance of your Jib cranes. Some cranes also need consistent recalibration.
- Safety of your workers: As your workers need to deal with your Jib cranes regularly, you have to ensure their safety. Jib cranes from reliable manufacturers are safe for use. Moreover, proper installation is important to prevent risks to the user. Structural issues in your Jib cranes may also be risky to your workers.
- What do you need to move? When you are going to choose a Jib crane of a perfect size, you have to ask this question to yourself. The load weight and size are relevant factors. You may need to move one or more than one object. For multiple objects, you have to find out how tight you are wrapping them. A sling may easily lift most of your items. However, while you need special handling, you have to focus on the crane size. Make sure that your chosen Jib cranes are capable of accomplishing heavy works.
- The travel path: After identifying the purpose of buying the Jib crane, you have to make out the height of lifting the load. For the indoor use of your Jib cranes, you must check out the ceiling height. With an increasing span and capacity, you can raise the beam depth and the headroom for the hoist. Moreover, you have to detect the presence of electrical lines. As your crane is a steel-made system, a simple touch with any electrical device may affect the crane.
You may think that Jib cranes are simple machines. However, buying the right one is not always easy. Based on your needs and purposes, you can purchase a Jib crane of a perfect model.
