R 984 C Liebherr excavator specs & Dimensions (2007 - 2010)

Productivity and Efficiency

Liebherr’s R 984 C mining excavator is the most flexible digging and loading tool. It can be customized for all mining applications for maximum performance. Even under the hardest conditions, it achieves high productivity. Always ready for job, the R 984 C is your key to the lowest operating and owning cost per tonne.

Reach a New Level of Productivity

With a multitude of possible backhoe attachments configurations and a wide range of buckets the R 984 C provides the highest crowd and breakout forces in every application. Even under tough conditions Liebherr’s R 984 C high digging force allows easy bucket penetration and favorable bucket fill factors to achieve high productivity.

Compact Machine Design

Liebherr’s excavator design is well-balanced and provides best machine stability. The high weight distribution towards the undercarriage contributes to an efficient utilization of the strong digging forces and a favorable power to weight ratio of the uppercarriage and attachment.

Buckets

GP: General purpose bucket with Esco V 69 SD teeth. HD: Heavy-duty bucket with Esco V 71 SD teeth. XHD: Heavy-duty rock bucket with Esco V71 SD teeth.

Safety and Environment

The Liebherr R 984 C provides uncompromising safety for operators and maintenance crews, with innovative technologies integrated into the machine.

Efficiency for Less Cost

Liebherr’s large dimensioned cooling system reduces fan power consumption and ensures an ideal machine temperature. The hydrostatic fans operate always on the required level.

Automatic Idle Control

The electronic control of the hydraulic system and engine allows automatic idle mode contributing to less fuel consumption and load on the engine.

Safety Integrated Design

All railings and catwalks are laid out to easily access all relevant machine areas. An optional wide catwalk is available. The laminated windows create a safe working environment for operators. Emergency stop arrangements in the cab and optionally in the engine compartment ensure safe maintenance tasks. Safety standards are achieved by a separated engine and pump compartment, heat insulation on turbochargers and on the exhaust system as well as by the use of heavy duty high resistant hydraulic hoses.

High Hydraulic Efficiency

The high pressure level of Liebherr hydraulic system together with the optimized pipe and hose layout maximize the usable power transmission. The Pressure Less Boom Down function combined with the oil regeneration on the attachment saves energy and reduces swing back time.

Extended Service Intervals

The R 984 C offers all features for extended machine services intervals. The technical layout of filtration systems with integrated bypass hydraulic oil filters and the large dimensioned grease systems are only some examples.

Closed Loop Swing Circuit

With an independent swing circuit, the machine allows the maximum swing torque whilst retaining the full oil flow for the working circuit.

Operating and Servicing

The R 984 C’s operator cab creates a comfortable and ergonomic working environment. Furthermore, the ergonomic component access and long service intervals assist the service team to ensure more uptime.

Comfortable Working Environment

The large R 984 C’s spacious cab offers ideal working conditions and first-class comfort. The fully adjustable seat and control fits to individual needs. The position of the operator station together with the large windows allow an outstanding visibility over the whole working environment. The cab’s effective insulation creates a quiet working environment for maximum productivity.

Ergonomic Control Elements

The configuration and placement of operator control elements and monitoring displays are perfectly coordinated to support the productive performance. The electronic control is easy and intuitive to use. The dashboard and machine control panel are easy to access and arranged for fast overview on major machine functions.

Ergonomic Service Access

The R 984 C provides ergonomic component access for fast and efficient service. All service points are within reach through large catwalks and walkways. The optional ground fast filling connections gives easy and safe refilling of service fluids, saving time, preventing spillage and reducing contamination by dust. The electronic health monitoring system assists in trouble-shooting and maintenance tasks. Liebherr excavators are equipped with louvers for easy access of ground based support tools.

Lift Capacities

The load values are quoted in tons (t) on the backhoe bucket's load hook, and may be swung 360° on firm and even ground. Values quoted in brackets apply to the undercarriage when in longitudinal position. Capacities are valid for 600 mm wide double grouser pads. Indicated loads are based on ISO 10567 standard and do not exceed 75% of tipping or 87% of hydraulic capacity (indicated via #). Maximum load for the backhoe bucket's lifting eye is 27 t. Without bucket (4.60 m³), the lift capacities will increase by 7,200 kg. Lift and lever they increase by an additional 1,900 kg. Lifting capacity of the excavator is limited by machine stability, hydraulic capacity and maximum permissible load of the load hook. When lifting loads, the hydraulic excavator must be equipped with automatic check valve on its hoist cylinders and overload warning device according to European Standard, EN 474-5.
