This is a completed toy designed for children and/or collectors.
Here's a set of five die-cast construction vehicles: a Komatsu hydraulic shovel PC200 Liftmag, a Nissan Diesel Big Sam flatloader truck, a Komatsu D85PX bulldozer, and a Suzuki Carry light truck. Very well painted, and of course each vehicle has at least one "gimmick" (moving parts).
