What is a wrecking ball?

A wrecking ball is a heavy steel ball suspended from a crane that is used for building demolition. Wrecking balls supplied by ONA are characterized by quality cast steel with excellent durability, helping to reduce overall operating and production costs.When breaking pieces of stone larger than the entry hole in the quarry, crushers can easily use energy balls falling from the height on the stone or to let stone hit the ball. ONA provides several sizes and weight categories for balls, we are willing to advise you with the selection.

Detailed introduction

Chemical Component

Core Components and Working Principleon 

1. Sphere: Typically made of high-density cast steel (such as the ZG270-500 you mentioned), with a diameter ranging from 0.8 meters to several meters, and weighing several tons or even tens of tons.

2. Suspension System: Consists of slings, chains, and a release mechanism from a crane (or a dedicated demolition machine).

3. Working Principle: The operator manipulates the crane to lift the steel ball to a certain height. By swinging or directly releasing the ball, it accelerates along a "pendulum" trajectory to strike the target (such as walls, columns, or floor slabs). At the moment of impact, the ball's enormous mass multiplied by its velocity generates extremely strong kinetic energy, sufficient to crush concrete, brickwork, and other building materials, causing the structure to crack, break, and ultimately collapse.

Main Features

1.Immense power: Capable of quickly destroying sturdy reinforced concrete structures.

2.Simple structure: The equipment itself requires virtually no maintenance and is highly reliable.

3.Low cost: Compared to some high-tech demolition methods, the initial investment and operating costs are low.

4.Wide applicability: Particularly suitable for demolishing independent, tall structures such as bridges, chimneys, and large industrial plants.

5.No electricity/hydraulic power required: The ball itself requires no power, relying solely on a crane.

 

Modern Application Scenarios

1. Demolition of large industrial facilities: such as abandoned steel mills, power plants, cement plants, and other spacious factory buildings.

2. Demolition of bridge piers and abutments.

3. Controlled demolition of tall structures such as chimneys and water towers (by precisely impacting the base to cause them to collapse in a predetermined direction).

4. Secondary crushing: used to break up large concrete blocks after initial building demolition.

5. Emergency rescue: used for rapid demolition of dangerous structures on the verge of collapse after earthquakes or fires.
