Part number 2402370A is a Handle Weldment, a precision-fabricated steel assembly specifically engineered for the Powerliner 5500 and Powerliner 4500 service line striping systems. This packaged component, designated PL4500, serves as the primary operator interface, providing the ergonomic grip points necessary for maneuvering the striper across job sites and maintaining precise control during parking lot, roadway, and athletic field marking operations. The welded steel construction ensures the rigidity required for safe transport and accurate line application.
The Powerliner 5500 features advanced SmartArm technology and DeadLock Handlebars that allow operators to adjust handlebar positioning in three planes for customized comfort and control. The handle weldment integrates with this adjustable platform, providing the secure foundation necessary for both single and dual gun configurations. This capability allows operators to stripe with either one or two guns simultaneously, significantly increasing productivity on large-scale projects. The handle assembly also provides mounting points for the control panel, ensuring all operator controls are within easy reach during operation.
As a weldment, this component is fabricated from multiple pieces of precision-formed steel plate and tubing, permanently joined through controlled welding processes to create a single, unified structure. This construction method provides superior strength and rigidity compared to bolted assemblies, essential for maintaining precise control under the continuous vibration and dynamic loads of high-production line striping. The handle weldment is subjected to extreme operational stresses including repeated lifting cycles, impact loads during transport, and continuous vibration from the engine and hydraulic drive system. Replacement with genuine 2402370A handle weldment restores proper operator control and ensures safe, reliable maneuvering.
| Operator Interface | Provides ergonomic grip points for maneuvering and controlling the striper |
|---|---|
| Control Panel Mounting | Secures operator controls within easy reach during operation |
| Structural Support | Welded construction withstands vibration and impact loads |
| Weld Cracking | Visible cracks at welded joints compromise structural integrity |
|---|---|
| Deformation | Handle is bent or twisted, preventing proper control panel alignment |
| Pivot Wear | Adjustment points are worn, causing handle drift during operation |
| Corrosion | Severe rust has weakened the steel structure or mounting points |
Part number 2402370A is specifically designed for the Powerliner 5500 and Powerliner 4500 service line striping systems. The Powerliner 5500 features advanced SmartArm technology and supports both single and dual gun configurations for versatile striping applications. This handle weldment is a model-specific component engineered for the mounting configurations, weight capacities, and operator interface requirements of these professional sprayer systems. The packaged PL4500 designation indicates it is ready for installation on compatible units. Always confirm fitment using the correct parts diagram for your exact model and serial number.
