Caterpillar P335

The Caterpillar P335 is a hydraulic pulverizer, or multi-functional concrete crusher, built as a passive work tool attachment rather than a powered machine — it carries no engine, ECM, transmission or undercarriage of its own. It is the third size step in Caterpillar's P315/P325/P335/P360 concrete crusher line, introduced in the late 2000s per the factory spec sheet for this family, and is sized for stick-mounted carriers in the 35-60 tonne class. Factory-listed compatible Cat excavators include the 325B/C/D, 329D, 330B/C/D, 336D, 345B/C, 365UHD BII/C and 385UHD B/C. The tool itself weighs about 3550 kg (excluding mounting bracket), with a jaw opening of 983 mm (38.7 in), jaw depth of 877 mm (34.5 in) and a 350 mm (13.8 in) cutter length. Closing force is rated at 160 t at the tooth tip and 355 t at the primary cutter, with crushing capacity up to roughly 800 mm (31.5 in) of concrete thickness. A 360-degree hydraulic rotator head and a standard speed valve are fitted, and the hydraulic circuit runs off the carrier: high-pressure lines for opening/closing (up to 350 bar, up to 300 l/min) and medium-pressure lines for rotation (up to 140 bar, 40 l/min).

Within Caterpillar's demolition attachment lineup, the P335 combines breaking, pulverizing and rebar/steel cutting in a single tool, reducing the need to swap between a hammer, shear and separate pulverizer on the same job. That combined function, plus its mid-size carrier fit, kept it a common choice on commercial demolition and concrete recycling sites through the 2000s and 2010s. In the used and parts market today, P335 units still trade through dealers and attachment resellers as a cost-effective option for shops running 35-60 tonne class excavators, with jaw tips, bushings and cylinder seals as the recurring wear-part demand. Caterpillar has since introduced a separate, newer primary pulverizer lineup (P318, P324, P332, P345, P365) with faster cycle times and higher crushing force. No factory documentation ties that newer series to the P335 as a direct replacement, so the two families should be treated as unrelated when sourcing parts or comparing specifications.
