ROKR Siege Heavy Ballista Story

There are two products in the Epic War series, namely KW401 Siege Heavy Ballista and KW801 Wheeled Siege Artillery. Based on the giant crossbows and cannons on the eastern and western battlefields in the medieval era thousands of years ago, they skillfully used the transmission between gears to recreate the ejection structure. In terms of appearance, both retain the concrete appearance of the cannon crossbow, and the wheeled cannon designed based on the classical canon has an atmospheric and thick shape; The heavy siege crossbow of medieval fantasy style perfectly integrates the real bed crossbow and the Dragon killing giant crossbow in the legend, revealing the hardcore and magnificent appearance of the siege crossbow.
