Wheel Barrows & Caste Wheels
wheelbarrow is a small hand-propelled vehicle with a single wheel at the front and two supporting legs at the back. It is designed to be pushed and guided by a person using two handles at the back. Caster wheels are wheels mounted to a fork, allowing them to rotate 360 degrees. Caster wheels come in various types, including swivel casters (which rotate) and rigid casters (which only move forward and backward).
