Advances in Hydraulic Excavators

The hydraulic excavator market is seeing new advancements. With the rising demand for infrastructure projects, along with the growing use of technically advanced hydraulic excavators, construction companies will have new equipment driving on to the jobsite.

One new example comes from Marubeni-Komatsu, which recently unveiled two new wheeled excavators. These machines are more compact and versatile, with an EU Stage IV engine and up to 13 percent lower fuel consumption.

Both have the same basic machine dimensions as previous versions, linkage, and main hydraulic valve. The engines’ electronic control system manages the airflow rate and the fuel injection, combustion parameters, and aftertreatment function, along with ultra-low emissions.

These pieces of equipment also come with advanced technology. For instance, they come installed with KOMTRAX telematics and the Komatsu Care Maintenance program. Also, the new auto-idle shutdown system prevents unnecessary fuel consumption and will shut the engine off and apply the parking brake and hydraulic lock after a preset idle time limit.

Further, an upgraded high-resolution widescreen color monitor panel provides key machine metrics including e-level, fuel consumption, and performance data. Also, Komatsu’s standard “KomVision” enhances safety through a system of multiple cameras: jobsite surroundings can be checked on the monitor prior to carrying out any operation.

With technology such as this, construction companies are able to protect the machines against misuse and guarantee maximum efficiency and uptime.
