Caterpillar VHS-40/3

The Caterpillar VHS-40/3 is a demolition and scrap-processing shear, an excavator-mounted work tool rather than a self-propelled machine. It carries no engine, no ECM, and no undercarriage of its own; it runs entirely off the carrier excavator's auxiliary hydraulic circuit through a dedicated shear cylinder and, on rotator-equipped units, a hydraulic rotation bearing. It belongs to the Verachtert-built Cat VHS-10/30/40/50/60/70 demolition-shear family, offered on a pin-grabber quick coupler or a fixed pin-on mounting bracket. No operating weight or jaw opening is published specifically for the VHS-40/3; sibling /3-generation units bracket the size class (VHS-30/3 runs about 1.9 t, VHS-50/3 about 4 t), so treat any specific figure attached to this model as unconfirmed rather than a fact. The /3 suffix marks a distinct shear generation, separate from the earlier base H/M-variant VHS-40 (documented around 2.5 to 3 t, with roughly 490 to 500 mm / 19.3 to 19.7 in jaw openings and a 20 to 35 t carrier class, figures that predate the /3 redesign and are not carried over as this model's own). The family runs alongside Cat's own in-house S-series shear line (S305-S385C class) covering the same size tier.

The move from the base H/M-generation VHS shears to the /3 generation brought a shared parts architecture across VHS-30/3 through VHS-70/3: mounting-bracket hardware, jaw pivot components, and rotator groups follow a common design scaled per model size, distinct from the earlier base-generation catalog structure. That commonality keeps parts sourcing workable across the family even where model-specific published specs are thin or missing outright, as they are for VHS-40/3. It's also why a niche Verachtert-badged attachment like this still matters in the used and parts market today: buyers aren't locked to one carrier brand thanks to interchangeable pin-on and quick-coupler mounting, and the parts that actually turn over in service are wear items, blades, pins, bushings, cylinder seals, and rotator bearings, not engine or driveline components. Cat's S-series shear line is the modern in-house successor path for this size class, with the VHS-40 tier tied to Cat's own S325 dealer designation, but plenty of VHS-40/3 units remain active in demolition and scrap fleets, keeping steady demand for jaw, pivot, and rotator service parts.
