Excavator, known as excavating machinery, is also an earthmoving machine that uses buckets to dig materials over or under the bearing surface and load them into transport vehicles or to the stockyard.
The materials excavated by the excavator are mainly soil, coal, sediment, and pre-loose soil and rock. Judging from the development of construction machinery in recent years, the development of excavators is relatively fast. Excavators have become one of the most important construction machinery in engineering construction. The three most important parameters of an excavator are operating weight (mass), engine power, and bucket capacity.
InquiryIndustry-leading performance and productivity
The combination of a newly improved engine and a redesigned driven hydraulic system with an attractive cost-performance ratio is unrivalled by any other hydraulic excavator in its class
Durability & stability
Manufactured with surprisingly strong materials and structures, the LT830-7 is unrivalled in durability and safety, allowing it to pass rigorous performance tests under extreme conditions. Whenever you work in a tough environment, you can count on JOOMACH’s LT830-7.
Easy maintenance
Short maintenance operations at long intervals increase the machine’s availability onsite at all times. JOOMACH has developed the LT830-7 to deliver even higher profitability to the customer.
Safe & comfortable
More space, wider visibility, better air conditioning, and a very comfortable seat – all these elements allow the operator to work safely and comfortably for long hours in the best possible conditions.
