Bucket-Wheel Excavators

TAKRAF Bucket-Wheel Excavators are continuous mining machines on crawlers used for removing overburden and extracting materials such as clay, sand, gravel, marl and energy resources.

The excavator is typically integrated into a conveyor system to transport the extracted material.

Bucket-wheel excavator models: compact to large-scale solutions

Bucket-wheel excavators are offered in different sizes, ranging from compact to large-scale machines, each designed to meet specific site conditions and project requirements. Design options include:

• Compact bucket-wheel excavators ideal for mines with short benches, irregular operating conditions and challenging terrain
• Large scale bucket-wheel excavators suited to flat mines with unconsolidated rock, large bench sizes and consistent mineral deposits

Design and key components of a bucket-wheel excavator

TAKRAF Group's bucket-wheel excavator designs emphasize efficiency, reliability and ease of maintenance. By customizing each machine to project specifications, we ensure efficient operation and long-term reliability.

The main parts of a bucket-wheel excavator include:

• The bucket-wheel with its buckets
• The bucket-wheel drive located at the head of the boom
• The slewable superstructure with a counterweight boom
• The substructure with crawler undercarriage and a transfer boom or loading unit (crawler-mounted loading bridge) for transfer of material to the bench conveyor
