A spider crane for sale is a mobile mini-crane with spider-like legs that can be adjusted for different types of terrain. They are known for their compactness, lightweight, and versatility in lifting loads. Here are the most common types:
Adjustment spider cranes
Adjustment cranes have adjustable legs, which allow them to level and stabilize themselves on uneven ground or slopes. This adaptability is a key feature that enhances the versatility of the crane in various outdoor and off-site construction settings.
Foldable spider cranes
Foldable leg cranes have a structure that can be folded up like a portable umbrella for easier transportation and storage. This feature makes it easier to move the crane between work sites and also saves storage space when the crane is not in use.
UU leg cranes
UU leg cranes have a unique leg configuration that resembles the letter 'U' set closely together. This design provides enhanced stability and support for the crane, especially when lifting heavy loads or operating in challenging environments.
Trailer spider cranes
Towing cranes are equipped with a trailer that allows the crane to be towed or transported using a vehicle. This type of crane is commonly used in outdoor spaces or remote locations where access by traditional trucks or vehicles may be difficult. The mobility provided by the trailer enhances versatility by allowing the crane to be brought closer to the work area.
Truck-mounted spider cranes
These versatile machines, which are often mounted on a flatbed truck, combine the mobility of a road vehicle with the lifting capabilities of a spider crane. This integration allows for easy and rapid deployment to a wide range of off-road and remote locations where conventional cranes may be impractical. Once on site, the crane can be detached from the truck to get closer to the lifting task.
The specifications of the mini spider crane vary depending on the model, but here are some common ones. One will want to check the maximum load capacity. If the crane has a higher weight capacity, it will be more useful in heavy lifting. What is the maximum reach? A crane with higher maximum reach allows for lifting objects from various positions. Another key spider crane specification is the power source. A crane with versatile power options can be useful in different working conditions. Most cranes have a compact design that allows them to maneuver easily in tight spaces.
Like any other machinery, a spider crane needs maintenance to enable it perform efficiently and prolong its lifespan. The most important maintenance tip is to always follow the manufacturer’s maintenance schedule. This ensures that the crane is well taken care of at all times. Performing routine inspections is equally important. Schedule for periodic inspections by a qualified crane inspector. They will be able to identify issues that are not visible to the operator. Remember to always perform pre-use inspections every time the crane is used. This will help identify any possible issues before they develop into bigger problems.
Lubrication is needed to keep the moving parts of the crane in good condition. Clean the crane regularly to remove dirt and debris that can cause damage to the crane. If necessary, apply protective coatings to keep the crane safe from corrosion. The maintenance guidelines above will go a long way in keeping the spider crane functional and extending its lifespan.
Spider cranes are used in various industries and applications where compactness, stability on rough terrain, and versatility are required.
Construction sites and infrastructure development
Spider cranes are commonly used in construction projects with limited space and rough terrain. They perform tasks such as installing precast elements, steel frameworks, roofs, and domes, as well as general lifting operations. Their ability to access confined spaces and navigate narrow passages makes them a valuable tool in construction.
Maintenance and repair industries
In maintenance and repair tasks, spider cranes are widely used in industries such as manufacturing, energy, and infrastructure. They provide access to high-elevation equipment, structures, and systems for maintenance. The ability to position themselves precisely and safely work at height makes spider cranes an ideal choice for these tasks.
Assembly and installation operations
These operations involve assembling and installing heavy machinery, equipment, production lines, and other industrial facilities. The precise positioning, stability, and high lifting capacity of spider cranes make them a preferred choice for assembly and installation.
Event and exhibition management
In event and exhibition management, spider cranes are valuable in staging, set construction, booth assembly, and equipment installation. Their versatility and ability to maneuver in limited spaces allow for the efficient and precise positioning of structures and equipment.
Demolition and deconstruction projects
Spider cranes are a suitable option for demolition and deconstruction projects in construction and urban renewal. Their ability to access confined spaces, stability, and high lifting capacity enable them to perform dismantling, demolition, and deconstruction tasks precisely and safely. Spider cranes reduce the need for temporary scaffolding and ensure safety and efficiency.
Agricultural and landscaping operations
In agriculture and landscaping operations, spider cranes are used to maintain and repair high-elevation crops, install structures, and perform lifting operations. Their ability to navigate rough terrain and stability make them suitable for work in agricultural and landscaping environments.
When buying a new mini spider crane, the following factors should be considered:
Work Environment:
As mentioned, the legs of the cranes can spread out wider than normal cranes. This is excellent for work areas with uneven ground. Moreover, they are great for outdoor areas with steep slopes or gradients. The mini crane can be used in tight spaces and areas where large equipment cannot access.
Lifting Capacity:
Determine the lifting capacity and range of the spider crane. Choose a model that can handle the required weight of materials. Additionally, check the reach needed for the specific tasks and projects. Some models have higher capacities and extends than others.
Size and Weight:
Consider the dimensions and weight of the crane. Choose a size that can navigate through job sites and transportation means easily. Think about the parking space required to store the crane when it's not in use.
Controls and Automation:
Inspect the type of control system used to operate the spider crane. Some models have remote control and automated features. These improve productivity and safety on the job site. Choose a crane with a control system that is easy to use and understand for the operators.
Cost and Budget:
Determine the upfront cost and long-term expenses of owning and operating the mini crane. Additionally, consider the maintenance, fuel, and insurance costs. Choose a crane that makes sense for the total cost of ownership and the budget for the project.
Q1: What is the maximum reach of a spider crane?
A1: The maximum reach of a spider crane varies depending on the model. Generally, the reach can go from around 8 meters to over 20 meters.
Q2: Can a spider crane lift at height?
A2: One of the benefits of spider cranes is that they can easily lift at height. They are designed to work in high places and tight spaces.
Q3: What are the benefits of using a spider crane?
A3: Spider cranes are designed for use in difficult terrain and tight spaces. They have a unique lightweight and compact design that makes them easy to transport. These cranes have high lifting capacities despite their small sizes. Spider cranes can also easily maneuver and set up on uneven ground.
