Bear Iron Works Papa Grizzly Rock Screen for Full-Size Loaders

The Bear Iron Works Papa Grizzly Rock Screen is the largest standard production Grizzly in the Bear Iron Works lineup, engineered for full-size loaders and demanding material-screening applications.

With approximately 6.8 cubic yards of screening capacity, a 144-inch internal width, and a 3,300 lb operating weight, the Papa is designed for heavy civil construction, aggregate processing, quarry work, mining, recycled concrete, large rocks, riprap, scrap material, and other high-impact screening applications.

Bear Iron Works reinforces the Papa beyond its smaller Grizzly models. The screening deck uses heavy-duty solid steel bars, while the frame incorporates a double-header design, additional cross rails, and structural gusseting to withstand the impact generated by larger loaders and heavier material. Bear specifically identifies the Papa as its heavy-duty choice for industrial and aggregate producers.

The standard configuration uses 3-inch screen spacing, with 4-inch, 5-inch, and 6-inch spacing also available. For finer material separation, the Papa can be paired with Bear Iron Works' removable crusher-mesh screen system, allowing operators to process material down to much smaller sizes without replacing the main Grizzly.

Which model should you choose?

Koala: Best for smaller yard tractors and ride-on skid steers handling landscaping and lighter screening applications.

Growler: Designed for compact skid steers and utility tractors where more capacity is needed without moving into a full contractor-size screen.

Cub: Best for standard skid steers and general construction screening.

Mama: Designed for backhoes, larger tractors, and heavier mid-size construction applications.

Papa: Choose the Papa for full-size loaders, heavy civil projects, quarry and aggregate operations, mining, recycled concrete, riprap, large rocks, and high-volume material screening.

Bear's 2027 equipment reference places the Papa in the approximately 14,600–42,000 lb loader range, using the CAT 908 through CAT 950 class as reference equipment.
