Chocky Bar

Chocky Bar

Chocky bars, also known as chocky blocks or wear bars, are a type of wear-resistant material used in various industries to protect surfaces from abrasion and impact. These bars are particularly common in applications where materials experience sliding or impact wear. The name “chocky” is derived from their use in chutes and hoppers where materials often get stuck or “chocked.”

Chocky Bars are unique block products, which can be formed and welded onto flat or curved surfaces. Chocky Bars can be used on a range of fixed plant and mobile equipment such as buckets and chute liners.

Wear Button

Wear Button

A wear button is a type of wear-resistant material used in industrial applications to protect surfaces from abrasion, impact, and wear. Similar to chocky bars, wear buttons are typically made from a combination of a wear-resistant white iron alloy and a steel backing plate. The wear-resistant alloy provides excellent hardness and toughness, while the steel backing plate adds strength and facilitates easy attachment to the surface that needs protection.

The wear button gets its name from its button-like appearance. It is essentially a small, circular or slightly domed wear-resistant insert that is welded onto surfaces that are prone to wear and tear. The buttons are strategically placed on the equipment or machinery where wear is likely to occur, providing localized protection.

Wear Bar

Wear Bar

A wear bar is a component designed to resist abrasion and reduce wear in various industrial applications. It is a wear-resistant element typically made of materials that can withstand the impact and friction associated with abrasive substances. Wear bars are commonly used in equipment and machinery where surfaces are subjected to continuous wear and tear.

Bolt protector

Bolt Protector

A bolt protector for construction and heavy equipment is a device or component designed to shield and safeguard bolts used in critical areas of machinery. Construction and heavy equipment often consist of numerous bolts that hold together various components, such as bucket teeth, cutting edges, or other wear parts. These bolts are exposed to harsh working conditions, including abrasion, impact, and debris, which can lead to wear and damage over time.
