Dozer Equalizer Bars | Heavy-Duty Undercarriage Components

Dozer Equalizer Bar Solutions for Maximum Stability & Undercarriage Protection

At TOSOG Yellow Plant Solutions, we specialise in the supply of high-strength dozer equalizer bars designed to deliver superior balance, traction, and long-term undercarriage protection for crawler bulldozers operating in the most demanding environments. Our equalizer bars are engineered to withstand extreme loads, constant vibration, abrasive ground conditions, and heavy impact, making them ideal for construction, mining, quarrying, bulk earthmoving, and civil engineering applications.

We offer a comprehensive range of OEM, premium aftermarket, refurbished, and complete equalizer bar assemblies, ensuring cost-effective solutions for both single-machine owners and large fleet operators. TOSOG supports a wide variety of crawler dozers used throughout South Africa and the African continent, with solutions tailored for local operating conditions, long duty cycles, and harsh terrain.

A dozer equalizer bar – also referred to as a track equalizer bar or suspension bar – is a critical undercarriage and suspension component that connects the left and right track frames to the main chassis of the machine. Its primary function is to allow controlled oscillation between the track frames, enabling both tracks to remain in constant contact with the ground, even when operating on uneven, rocky, or sloped surfaces.

By evenly distributing machine weight across both tracks, the equalizer bar:

• Enhances overall machine stability

• Improves traction and pushing performance

• Reduces stress on track frames, rollers, idlers, and final drives

• Minimises uneven undercarriage wear

• Improves grading accuracy and operator control

A properly functioning equalizer bar plays a vital role in extending undercarriage service life, reducing downtime, and lowering total operating costs, particularly in high-impact and high-load applications common across African job sites.

What Is a Dozer Equalizer Bar?

A dozer equalizer bar is a heavy-duty suspension component mounted between the track frames and the main chassis of a crawler dozer. It allows controlled oscillation between tracks so that both tracks remain in contact with the ground, even on uneven or sloped surfaces.

Key Functions:

• Balances load across left and right track frames

• Improves traction and grading accuracy

• Reduces stress on track frames and mainframe

• Protects rollers, idlers, and final drives

• Enhances operator control and machine stability

Frequently Asked Questions (FAQ)

What does a dozer equalizer bar do?

It balances the dozer’s weight across both tracks, allowing each track to move independently over uneven terrain.

Is an equalizer bar part of the undercarriage?

Yes. It is a critical undercarriage and suspension component.

Can I rebuild an equalizer bar?

Yes. Pins, bushings, and bearings can often be replaced if the bar body is not cracked.

OEM or aftermarket – which is better?

High-quality aftermarket equalizer bars often offer better durability at a lower cost, especially in harsh environments.

Do you supply complete assemblies?

Yes. TOSOG supplies complete equalizer bar assemblies and individual components.
