Strela (crane)

A strela is a type of crane that moves heavy things from one place to another. It has a tall, long arm with a hook at the end of it. The strela is operated by an operator who sits in a cabin at the bottom of the crane and controls it using a remote control. The operator can move the strela's arm up and down and swing it around to pick up and move heavy objects from one place to another. It's very useful for construction sites, warehouses, and factories because it can move heavy objects quickly and safely.
