First ever produced Komatsu blasthole drill model in 1:50 scale, Introducing the Komatsu ZR77 Blasthole drill The model is an impressive 19" high, close to 11" long and just under 6" wide!! This is another model to add to the growing 1:50 mining collection. If you have the 1:50 XPC, the L-1850 and the 1:50 Continuous Miner, then this is next on the list. This model is 80% diecast construction with the following diecast components... (Chassis, Frame rails, track shoes, handrails, A-frame, mast, cabin, hydraulic lines) the balance of the model parts are a combination of photoetch and of course plastic for detail. The drill can be displayed with the mast folded down, or in the vertical drilling position, But thats not all, this model replicates ANGLE Drilling!! We are very excited to finally announce this model.
