Excavator equipment is powered by diesel. This is mainly due to diesel’s high torque output at low speeds, which is ideal for penetrating tough materials and moving heavy loads. Additionally, diesel’s superior energy density results in improved fuel efficiency compared to gasoline — a crucial factor for cost-effective mining operations. Diesel engines are also inherently robust and can withstand harsh conditions, ensuring reliability and minimal downtime even in challenging settings.
Excavator operators skillfully manoeuvre these massive machines using a combination of pedals and levers. These controls govern the machine’s movement, enabling precise steering and seamless transitions between forward and reverse gears. The powerful diesel engine drives the tracks and propels the excavator across challenging terrain. Meanwhile, hydraulic systems control the excavator’s arm and bucket for precise digging, lifting and loading.
The arm of this machine (such as those found in Komatsu excavators) is incorporated into the lower frame chassis. It comprises three hydraulic pistons that operate in tandem with steel piston arms, granting the operator remarkable control and flexibility.
The two main sections and the bucket loader are connected by a hinge. Extending the first piston increases the arm’s length, providing further reach for the operator. The third piston activates the bucket loader, which enables debris collection into the bucket.
To further optimise its digging capabilities, the excavator bucket is typically equipped with specially designed teeth, engineered to tackle various soil types and quickly break down stubborn materials.
Essential to an excavator’s operation, the tracks provide the traction and stability needed to access remote sites, traverse uneven ground and overcome obstacles that hinder other types of heavy machinery. These tracks, often resembling those found on tanks, are driven by the powerful diesel engine. Through a series of gears and hydraulic systems, the operator can control the tracks’ movement, enabling the excavator to manoeuvre forward, backward and even pivot in place.
Moreover, the tracks’ wide surface area distributes the excavator’s weight evenly, minimising ground pressure and reducing the risk of getting stuck in soft or unstable terrain. Whether it’s climbing steep slopes, crossing rocky landscapes or working in muddy conditions, the tracks ensure the excavator remains a reliable workhorse.
More complex pieces of equipment involve manipulating more than one track simultaneously, though this is not the case with every excavator for sale.
