20-Ton Workhorses: The Ultimate Guide to Vikfin’s Top-Selling Parts for SA’s Most Popular Excavators

In South Africa’s earthmoving landscape, one excavator size dominates the job sites, mining pits, scrapyards, plant hire fleets, and construction trenches: the 20-ton workhorse. This class of excavator—reliable, powerful, and just the right size for most projects—has become the backbone of operations both big and small.

At Vikfin, we know the 20-ton excavator inside and out. From our extensive dismantling operations to our precision testing procedures, we specialize in supplying high-quality used OEM parts for this vital machine category. If you’re looking to keep your 20-tonner running smoothly without blowing your budget, this blog is your ultimate buyer’s guide to our top-selling 20-ton excavator parts—all available at prices that beat the market.

Let’s break it down.

🛠 Why the 20-Ton Excavator Rules in South Africa

Before diving into our parts list, it’s worth understanding why the 20-ton excavator is king in SA:

• Perfect size-to-power ratio: Small enough to be transported easily, but powerful enough to tackle mining, demolition, construction, and scrapyard work.

• Affordable ownership cost: Both new and used, 20-tonners offer a solid ROI.

• Popular OEM support: Caterpillar, Komatsu, Hitachi, Hyundai, Volvo, Doosan, and Case all have flagship 20-ton models with reliable parts availability.

• Easy access to spares: Especially when you’re working with specialists like Vikfin who stock a wide range of used OEM parts for these machines.

Now, let’s look at the top-selling parts we stock—and what makes them essential.

🔩 1. Engines – The Beating Heart

We stock complete engines from models such as:

• Volvo EC210B – D6E

• Hitachi ZX200 – Isuzu AI-4HK1
