Titan 779-011 Caster Frame

The 779-011 caster frame is a structural component that forms the rear or front mounting point for swivel casters on compatible ProMark II and PowrLiner airless sprayer carts. It is typically fabricated from heavy-gauge steel and designed to withstand the rigors of job site transportation, including rough terrain, loading into vehicles, and continuous movement across uneven surfaces. The frame provides precise mounting holes and alignment features that ensure casters are positioned correctly for optimal steering and stability. When combined with quality swivel casters, this frame allows the sprayer to be pushed, pulled, and turned with minimal effort, reducing operator fatigue during long days on site.

Over time, caster frames are subjected to significant stress, particularly when sprayers are moved over curbs, thresholds, or debris. Impacts can bend the frame, causing misalignment that leads to uneven caster wear, difficult steering, or the sprayer sitting crooked. Corrosion from exposure to moisture, paint spills, and cleaning agents can weaken the metal, leading to cracks or failure at weld points. A damaged caster frame compromises the mobility of the sprayer and can make it unsafe to move, particularly on stairs or ramps. Replacing a bent or corroded frame with part 779-011 restores the original geometry of the cart, ensuring that all four casters contact the ground evenly and that the sprayer rolls straight and turns smoothly.

Installation of a new caster frame typically involves removing the old frame, which may be bolted or welded to the sprayer chassis, and attaching the new frame using the appropriate hardware. It is an excellent opportunity to inspect and replace the casters themselves, as worn casters can accelerate wear on a new frame. The 779-011 frame is manufactured to original equipment specifications, with precise hole locations and proper material thickness to ensure a direct bolt-on replacement. Whether renovating an older sprayer or repairing damage from a job site accident, this caster frame restores the mobility and stability that professionals depend on for efficient operation.
