759-120 Suretrak floating gun mount is a specialized mounting system designed to allow the spray gun to follow surface contours on compatible PowrLiner striping machines. This floating mount enables the gun to move vertically, maintaining consistent line width and edge definition even on uneven surfaces. A properly functioning floating gun mount helps produce professional striping results across varying pavement conditions. This mount restores original floating gun capability on compatible units.

The 759-120 Suretrak floating gun mount is a specialized mounting system that allows the spray gun to maintain consistent tip-to-surface distance on compatible PowrLiner striping machines, even when operating over uneven or irregular pavement surfaces. Unlike fixed gun mounts that hold the gun rigidly to the machine frame, this floating mount incorporates vertical movement capability that enables the gun to follow surface contours as the machine moves. This surface-following technology ensures that the distance between the gun tip and the pavement remains constant, which is critical for producing uniform line width and clean edge definition across varying surface conditions.
Fixed gun mounts can cause line width variation when the machine encounters dips, crowns, or uneven sections of pavement. As the machine moves over these irregularities, the fixed gun maintains its position relative to the machine frame rather than the pavement surface, resulting in inconsistent material deposition and ragged line edges. The Suretrak floating mount addresses this challenge by incorporating durable pivot points and spring tension components that allow smooth vertical movement while maintaining precise lateral positioning. This technology is particularly valuable on older pavement surfaces, asphalt repairs, and areas where surface consistency cannot be guaranteed.
| Surface following | Allows the spray gun to move vertically, following pavement contours |
|---|---|
| Consistent line width | Maintains uniform tip-to-surface distance for even material deposition |
| Edge definition | Preserves clean line edges across uneven or irregular surfaces |
| Inconsistent line width | Line width varies noticeably when machine encounters uneven pavement |
|---|---|
| Binding movement | Mount does not move freely or sticks during operation |
| Excessive play | Noticeable lateral movement or looseness in the mounting system |
| Visible damage | Bent components, worn pivot points, or damaged spring mechanism |

When servicing the floating gun mount system, these additional components are frequently inspected or replaced at the same time.
The gun should be inspected for proper function and alignment when mounted to the floating system.
Control cables should allow for the vertical movement of the floating mount without binding.
Bolts, pins, and bushings used to attach the floating mount to the carriage should be inspected.
