R 976-E/R 980 SME-E - Product Description

Powertrain and Design

The R 976-E and R 980 SME-E machines are equipped with an electric motor rated at 400 kW / 544 HP. Their design features a welded structure and cast steel components, which increases durability under stress and extends the service life of the machine. Additionally, safety valves prevent damage to lifting cylinders, enhancing operational efficiency and safety. The energy-efficient regeneration system reduces consumption during operation.

Undercarriage and Hydraulics

The undercarriage of the R 976-E and R 980 SME-E features a rigid X-profile design for greater stability. It includes chamfered double grouser track pads, facilitating maneuverability in difficult terrain. The hydraulic system is characterized by two variable displacement pumps that support both propulsion and equipment operation. The application of a closed-loop circuit for swing drive enhances operational efficiency.

Operating Parameters

The operating weight of the R 976-E ranges from 90,550 kg to 97,100 kg, while the R 980 SME-E ranges from 100,450 kg to 104,200 kg. The bucket capacity for the R 976-E ranges from 2.00 to 6.80 m³, and for the R 980 SME-E from 4.40 to 7.20 m³. The maximum reach with a full swing can extend to 5,900 mm, and the maximum digging depth reaches 12.93 m. The hydraulic system output can reach a maximum of 1,134 l.

Optional Equipment

The machines offer a wide selection of attachments depending on the application, including various bucket types (standard, HD, HDV) and different boom lengths. The option of an automatic lubrication system allows for efficient and safe maintenance. Additionally, features such as a climate-controlled cabin and high-quality touch screen are available.

Safety and Technical Data

The R 976-E and R 980 SME-E are equipped with numerous safety features, such as monitoring cameras that provide excellent visibility around the machine. The cabin features impact-resistant glass and a design that ensures maximum visibility. Technical parameters, including a maximum pressure of 350 bar in the hydraulic system, ensure high operational efficiency.
