Scale Model Excavator

This 1/50 scale diecast replica of the Komatsu PC78US-11 excavator arrives in the manufacturer's original unopened packaging. It is an officially licensed product built for adult collectors and hobby enthusiasts who value true-to-scale detail. The model combines diecast metal construction with select plastic parts for accurate representation.

Build Integration Details

The fully functioning metal blade, boom, arm and bucket move freely for dynamic display or diorama positioning. Free-rolling metal tracks allow the model to be repositioned without lifting, while 360 degree rotation between the track frame, machine base and operator cab adds operational realism. The detailed interior and exterior finish completes the presentation on a shelf or in a scene.

Capacity And Headroom

At approximately 4.75 inches long, 2 inches wide and 2.25 inches high, the model fits standard display cabinets and diorama bases without special accommodation. The fixed 1/50 scale means it cannot be resized for larger layouts, and the single-unit construction offers no modular expansion for builders who want articulated add-ons.

Questions about this item

Will the 360-degree rotation between the track frame, base and cab stay smooth after repeated handling?

The model uses metal-on-metal joints for the 360-degree rotation; with no motor or spring, friction stays low as long as dust is kept off the pivot points.

Does the diecast body or the free-rolling metal tracks get noticeably warm if the excavator sits under a display lamp all day?

Diecast zinc alloy and steel tracks are passive materials — they only reach ambient temperature, so a typical display lamp adds no perceptible heat.

The model arrives fully assembled in the original unopened box, so no tools or glue are required — is that correct?

Yes, the excavator ships complete in the manufacturer's sealed packaging; the functioning blade, boom, arm, bucket and 360-degree rotation work straight from the box.
