Mounting arm for National Crane 900

The mounting arm, part number 147249, acts as a structural component within the crane assembly. Its primary function is to provide an anchor point for secondary equipment, such as lighting systems, auxiliary supports, or counterweight configurations. By securing these elements to the crane chassis or super-structure, the arm ensures that accessories remain stable during lifting operations and machine movement.

This component is engineered for the National Crane 900 crane model. It is designed to align with the specific mounting points on the crane to facilitate proper installation and integration with the machine frame. The arm is intended to support the loads associated with the attached accessories while maintaining the structural integrity of the mounting location.

In heavy machinery, mounting arms are used to distribute forces and secure auxiliary hardware to the main structure. They provide the necessary interface between the crane frame and external components, ensuring that all attachments are held firmly in place during the dynamic stresses of crane operation. Regular inspection of the mounting points and the arm itself is standard practice to ensure that the connection remains secure and that the structural alignment of the crane is maintained.
