A jib crane is a lifting device with an arm or boom that mounts on a tower, allowing the crane operator to reach high places. The arm can rotate and tilt and be positioned in many ways so that the crane can lift or lower materials. It also offers more excellent maneuverability than a swing-load crane when all four jibs are raised and lowered together. Jib cranes are typically used for construction, demolition, electrical work, and other industrial applications.
As many different jib cranes are available, it is important to understand their main differences before selecting one. Jib cranes are adapted to suit various applications, and the physical and mechanical differences between models may determine which type is best for a particular task.
1. What is the Purpose of a Jib Crane?
Jib cranes are commonly used for lifting and moving materials. They are often used for demolition, structural work, and painting. They have the versatility to perform a wide array of functions: They are not limited by space like telescopic or forklift trucks. This flexibility allows the crane to reach high places, making it suitable for construction, demolition, and electrical work. The jib also offers greater maneuverability than an overhead crane when all four jibs are raised and lowered together.
2. How Much Can a Jib Crane Lift?
This is a huge range allowing movement between several building sites with ease. The ability to move materials in high places helps the crane crew reach hard-to-reach areas like rooftops, which makes it more efficient in completing tasks.
Jib cranes have different capacities, with more capable models being more expensive. Most jib cranes’ maximum lifting capacity ranges from 1 to 15 tons. A few models offer significantly higher capacities of up to 35 tons, and some manufacturers choose several models that differ in lifting capacity.
3. What Structural Support Options are Available?
While most cranes can be installed at ground level or on a rooftop, some can also be installed on the side of a building. While this configuration is possible with all types of jib cranes, it is recommended only for designated rooftop cranes as it dramatically increases the difficulty and risk of installation.
The pivot is at the center of gravity, so it doesn’t require extensive use of load-bearing supports or shoulders. This type of support also extends the working life of the crane by protecting it from damage and making it easier to maneuver. Some parts must contact an elevated surface, and other attachments impractical for this type of support, such as roof mounts or foundation plates.
4. What Type of Hoist Can Go on a Jib Crane?
Hoists are used to lift and lower loads. They are powered by an engine or an electric motor connected to the hoist rope through a series of gears called a sheave assembly. The hoist can attach directly to the jib and use the jib’s rotation to elevate or lower the load. It can be mounted in a rotating hook at the end of the jib. Available for jib cranes made with a base, a mast, and a head. These hoists have different sizes and strength options to fit the operator’s needs and the crane’s intended use.
Every kind of hoist has its advantages and disadvantages. Manual and hydraulic hoists are the most common due to their low cost. Mechanical and air-powered hoists are often used for lifting heavier loads, especially loads more significant than 20 tons. Electro-hydraulic and hydraulic hoists are more expensive than manual ones, but they are faster and more efficient at lifting higher quantities of materials. This allows lifting more material than a single-jib crane and offers greater maneuverability than an overhead crane with four jibs raised and lowered together.
It can be intimidating to buy a jib crane, but when done right, it can be a great tool to save money. When considering which model is suitable for you, it is important to make sure that the jib crane meets your needs, your budget, and your company’s capabilities. Choose a jib crane with a suitable range of capacities and structural supports to ensure that the crane can perform all of your lifting needs in the safest way possible.
