1. Container Lifting Spreader Beams
One of the most common lifting attachments for RTG cranes is the container lifting spreader beam. These attachments are designed to lift shipping containers efficiently and safely. Custom spreaders can be designed to accommodate different container sizes, such as 20-foot, 40-foot, and 45-foot containers, ensuring that the container handling gantry crane can operate in any container terminal or port environment.
Spreader beams come in different configurations, including two-point, four-point, and adjustable spreaders. Custom spreaders are designed to fit specific container types, ensuring a stable lift and reducing the risk of container damage during handling.
2. Grab Buckets
In industries where loose materials like coal, gravel, or scrap metal need to be moved, grab buckets are ideal for RTG cranes. These attachments can be custom-designed to accommodate different materials, from bulk solids to irregularly shaped objects. The design of the grab bucket can vary based on the size of the load, its weight, and the required grip.
For instance, in a port or shipyard setting, grab buckets can be customized to handle large quantities of bulk cargo, while in the construction industry, they can be modified to lift heavy concrete or construction materials. Custom grab buckets ensure that the RTG crane can perform these specialized lifting operations without risk of spillage or material damage.
3. Magnetic Lifting Attachments
For lifting ferrous materials like steel coils, beams, and scrap metal, magnetic lifting attachments are an excellent solution. These attachments use powerful electromagnets or permanent magnets to secure the load during transport. Custom magnetic attachments can be tailored to meet the lifting capacity requirements of the RTG crane while ensuring safe and efficient handling of metallic objects.
Magnetic lifters are especially useful in steel mills, scrap yards, and construction sites where metal objects are frequently moved. A custom magnetic lifting system ensures that the RTG crane can handle materials of varying sizes and shapes, maximizing its utility in different industries.
4. Forks and Pallet Lifting Attachments
In warehouses and distribution centers, fork attachments are often used for moving pallets and stacked materials. Custom fork attachments for RTG cranes can be designed to handle a range of materials, from large boxes and equipment to smaller, more delicate items. These attachments ensure that materials are lifted and transported safely, reducing the risk of damage during movement.
Custom fork lifts can be built with adjustable widths, length adjustments, and various weight capacities to suit different operational needs. Whether it’s a high-density storage system or a facility dealing with large-scale shipments, custom fork attachments increase the versatility of RTG warehouse gantry cranes in various storage and logistics environments.
5. Specialized Hooks and Slings
In addition to the more commonly used attachments, RTG cranes may also benefit from specialized hooks and slings for specific loads. Custom lifting slings can be designed for lifting tall, awkwardly shaped, or delicate items that require a more secure connection to the crane. These attachments are particularly useful for handling machinery, structural components, or oversized items that cannot be lifted with conventional hooks.
Specialized lifting hooks and slings are engineered with the right material and strength characteristics to match the load’s shape, size, and weight, enhancing the stability and safety of the lift.
Factors to Consider When Designing Custom Lifting Attachments
When designing custom lifting attachments for RTG cranes, several factors must be taken into account to ensure the solution is effective, safe, and efficient:
1. Load Characteristics
The weight, shape, and fragility of the load are critical factors when designing a custom lifting attachment. For example, heavy, dense materials like steel coils may require a completely different attachment than lighter, fragile items like electronics or glass panels.
