Caterpillar VPG-25

The Caterpillar VPG-25 is a mechanical demolition and sorting grapple, the smallest unit in Cat's V-series grapple lineup alongside the larger VPG-35, VPG-45, and VPG-55. It is a passive work tool with no engine, no ECM, and no independent hydraulic tank or pump; the jaw cylinder draws hydraulic flow directly from the host excavator carrier's own circuit. It mounts to an excavator-class carrier through a dedicated bracket documented in Cat's parts catalog under carrier mounting brackets, a mechanical grapple arrangement, and a jaw group assembly, cross-referenced by a mounting chart. No public spec sheet, weight figure, dimensional data, or serial-prefix scheme has surfaced for this exact model; documentation is limited to the parts catalog structure rather than a published Specalog, so operating weight and carrier-class range are not stated here rather than estimated.

Cat's parts records show no distinct generational split for the VPG-25 itself; it appears as a single arrangement sized at the small end of a family graduated by carrier class, with the VPG-35/45/55 covering progressively larger carriers. Grapples in this size are used for demolition sorting, material handling, and scrap loading where an operator needs to grab and orient irregular loads rather than dig or cut. Because the tool has no powertrain of its own, its service life comes down to wearing mechanical parts: pins, bushings, jaw hardfacing, and the cylinder. That keeps units running well past any new-sale window, and it is why pin/bushing and cylinder parts availability, along with bracket fit to a given carrier, drives value and usability in the used-attachment market.
