Lubricate moving parts to reduce friction and prevent rust. Keeping components well-oiled ensures smooth operation, especially for crawler crane attachments like grapples and clamshell buckets, which have multiple moving parts.

Cleaning and Storage

After use, particularly in harsh environments like dredging or demolition, clean the attachments thoroughly to remove dirt, debris, and corrosive materials. Proper storage is also critical to avoid environmental damage, particularly for sensitive components like hydraulic hoses or sensors.

Service Records

Maintain service records for all crawler crane parts and attachments. Keeping detailed records ensures that inspections and maintenance are performed at the right intervals and allows you to track the longevity and performance of each equipment.

Using Outriggers for Certain Crawler Crane Attachments

Outriggers are retractable metal legs that extend from the crane's base to provide additional stability when lifting heavy loads. They are primarily used with mobile cranes to give the support needed to stand still.

While crawler cranes are known for their stability due to their wide tracks that distribute the load evenly without additional support, some attachments may still require extra support to ensure safe and efficient operations. This is where outriggers come into play.

How Outriggers Work with Attachments

Outriggers are telescopic legs that extend horizontally and then vertically from the sides of the crane. Once deployed, they distribute the load more evenly over a larger surface area, helping the crane maintain its balance. This is particularly useful when using heavy-duty crane attachments like dragline buckets, which are designed for deep excavation and moving large volumes of material.

For instance, if a crawler crane is equipped with a grapple saw for forestry work like the image added above, the crane might need to maneuver heavy or awkwardly shaped materials. The additional weight or the complexity of the movement could cause instability, especially if the crane is operating on a slope or uneven terrain. In this case, deploying outriggers adds an extra layer of safety, ensuring the crane remains steady during lifting and maneuvering.
