Performance

These new electric Material Handlers have been designed to meet the speciﬁ c needs of industrial handling. A wide range of equipment and uppercarriages optimized for long working radius provide the ideal answer to all the demands which arise in the industry. The performance of the kinematic chain formed from components from our in-house production, combined with the power of the electric motor, maximize the performance of the machine when it comes to lifting power, precision, and speed of operation.

Reliability

Backed by more than 30 years experience in the construction of electric excavators, Liebherr designed the new EP 934 C, EP 944 C and EP 954 C with the aim of providing top performance whatever the challenge might be. The structure of the machine, using components from our own manufacture for the electric drive, has been completely rethought, and so moves away from simply being an adaptation of a diesel-engine machine. Being intended for key functions in the organization of industrial sites, Liebherr electric Material Handlers provide a very high level of reliability. The service life of the hydraulic components has also been increased, thanks to the smoother movement of the electric drive. The concept of the single actuator (one single electric motor for all the hydraulic functions) allows for the risk area associated with the low voltage at the electric cabinet to be reduced even further.

Comfort

Helping the operator to concentrate on his work and get the best out of his machine is achieved by providing a comfortable driving position, good visibility, and a highly ergonomic layout of the controls. The new electric Material Handlers offer the same level of comfort as on the mobile excavators (arrangement of the controls, driver’s seat, climate control, large window areas, etc.). The electric motor system adds a further layer of comfort thanks to the low noise emissions and absence of vibration. For Liebherr, comfort also means ease of daily maintenance of the machine in terms of access to the service and inspection points, so as to minimize downtime.

Economy

Investing in the acquisition of an electric Material Handler is a great long-term advantage. Constant increases in the costs of conventional energy sources are pushing up operating charges, and reducing proﬁ t margins considerably. Environmental criteria, in particular CO2 emissions, are also playing a constantly greater part in the choice of power systems and working methods. With the electric drive, Liebherr offers an economical alternative to conventional diesel-engine machines, and a solution with real respect for the environment.

Ideal balance between power, speed, and precision

• When it comes to handling metals, timber, or any other application, a wide choice of equipment in a broad range of conﬁ gurations means that the most varied demands can always be met by speciﬁ c solutions

• Optimization of the Material Handlers goes well beyond just the choice of equipment. It even includes the adjustment of the hydraulics to meet the needs of the site and of the operator

Great lifting power

Excellent Working Radius

Fast work cycles

Thanks to the optimised rear offset and the broach kinematics of the equipment, the design concept of the new uppercarriages means they can operate at exceptional outreach whilst guaranteeing a good balance of forces and better absorption of mechanical stresses.

Tough and designed for the most demanding of applications, Liebherr equipment systems are the perfect answer to every requirement when it comes to lifting power and range of outreach. Components are optimised by the ﬁ nite element calculation method.

The EP 934 C, EP 944 C and EP 954 C electric excavators are ﬁ tted with the Liebherr Torque Control system. The hydraulic guidance system on the excavator operates as a closed circuit, and does not affect the speed of movement of the equipment during the working cycle. The high torque and high oil delivery from the guide pump maximize the excavator rotation speed. A two-pump hydraulic system allows for operating speeds to be reached which are unequalled anywhere. Regeneration on the circuits for the equipment allows for optimization of the hydraulic power available and minimizing response time to the operator’s commands. This all results in a ﬂ uidity of movements which operators really appreciate.

Distributor

• Fine response of hydraulic control for maximum working precision

• Immediate response to operator‘s commands

• Three-pump hydraulic system, one of which is a closed circuit dedicated to the slewing of the Material Handlers

Precision of work

The ﬁ ne response of the hydraulic control allows for exceptional precision of work to be achieved at long outreach, which contributes to the comfort and convenience of the operator as well as achieving high performance results. Power is nothing without control.

Tough structure

• High strength steel sheet at points subject to severe stress, stands up to the most extreme demands

• Stable mounting of equipment elements

• Exceptional strength, even under intense loading

Electrical system

Protected electric cabinet

Electric motor

Totally integrated into the structure of the uppercarriages and accommodated in a metal container, the electric cabinet provides a three-fold level of protection to the components of the electrical system:

- Mechanical (insulation from vibrations and from the possible impact of falling objects)

- Heat (maintains a constant temperature thanks to the heating resistors which prevent corrosion from condensation)

- Electrical earthing of the structure and disconnection from current is controlled from the cab by way of a motorised circuit-breaker.

The electric cabinet, like the rotating joint, provides IP55 class protection. A double ﬁ ltration system (accessible from the outside) places the cabinet under pressure, which avoids any dust penetration and, with permanent ventilation, ensures the thermal balance of all the components.

Liebherr electric excavators are equipped with motors especially designed for really tough applications. The dimensions of the motor allow for the full power to be drawn from the kinematic chain, and so maximises the performance of the machine. The motor can resist a momentary overload of up to +25 % of its rated capacities. Protected against penetration by water and dust, its properties correspond to protection class IP55. The temperature of the roller bearings and other bearing elements is constantly monitored, and, in the event of overheating, the operator is warned of malfunction on the console at the driving position.

Cooling system

• Generous dimensions for high cooling capacity

• Vertical arrangement for increased efﬁ ciency and minimal incursion of foreign bodies

• Powered by a thermostatically regulated hydraulic motor

• Hinged to allow for complete cleaning

• Reversible actuation of the fan (without time limit) as option

Elastic base

• Complete range of elastic bases especially designed for each model

• Absorption of mechanical stresses (normally transferred to the chassis of an excavator) if mounted on a rigid structure (anchored metal body, concrete body)

• Protection for the machine (in particular the elements of the rotation assembly), as well as for the load-bearing structure, against the axial and radial forces generated by the operating dynamics

Cab with control panel

• The command arrangement for putting the electrical system under voltage is progressive (3 functions) and the emergency stop button allows for the general cutting of the electric cabinet supply

• Available as an option is a cut off system deriving from one source point, which can be activated from the driving position via an additional rotating joint

Comfort

Helping the operator to concentrate on his work and get the best out of his machine is achieved by a driving position which provides comfort, good visibility, and a highly ergonomic layout of the controls. The new electric Material handlers offer the same level of comfort as on the mobile excavators (arrangement of the controls, driver’s seat, climate control, large window areas, etc.). The electric motor system adds a further layer of comfort thanks to the low noise emissions and absence of vibration. For Liebherr, comfort also means ease of daily maintenance of the machine in terms of access to the service and inspection points, so as to minimize downtime.

Driving position

Wide walkway with safety rail

Low noise emissions

Carbon gas emission

Mounted as standard on a ﬁ xed platform of 1 200 mm (2 000 mm or hydraulic platform on request), the new cab on the electric excavators meets all safety standards in force (24 V supply in the operator's compartment), comfort, panoramic visibility, and ergonomic arrangement of the controls for perfect control of the machine.

Arranged on the upperdeck, combines safety and convenience for accessing all the maintenance points on the machine. Access to the lower structure (metallic base, concrete pedestal, chassis) can be tailor-made depending on the type of installation.

Liebherr electric excavators are really quiet in operation. Their measured acoustic level is from 4 to 5 dB lower than an equivalent diesel-engine version. The level of noise intensity from a Liebherr electric excavator represents less than a third of the noise generated by a diesel-engine unit.

Zero grams of CO2 emitted per tonne of product handled!

Flexibility and versatility

Energy costs cut

Increased service life

Maximum availability

Liebherr electric Material Handlers are multi-tasking machines. With a wide range of tools, which can be combined with Liebherr quick-coupling systems, they can create a degree of ﬂ exibility and versatility which has no comparison anywhere.

The energy yield from an electric motor is greater than that of a diesel-engine. Delivering the same kW output in hydraulic power costs three to ﬁ ve times less with an electric excavator than with a diesel-engine unit. Liebherr excavators deliver the full power from their kinematic chain and at a lot less cost.

The smooth actuation of the electric drive and the reliability of Liebherr hydraulic components mean that the maintenance costs of the excavator can be reduced considerably. The absence of vibrations and variations in output from a motor, which operates on a torque principle and at constant output, means that the stress on the kinematic chain can be reduced and the optional pre-heating of the hydraulic system allows for the hydraulic oil to be kept at an optimum temperature right from the start.

The costs associated with maintenance operations are reduced to a minimum, and that also cuts downtimes. The electric motor does not require any maintenance beyond lubrication of the bearings every 3,000 hours. No ﬁ lters (air, oil) to be changed and no draining of engine oil throughout the entire service life of the machine.

Height Can be slewed through 360° In longitudinal position of undercarriage Max. reach * Limited by hydr. capacity

The lift capacities are stated in metric tonnes (t) on the lifting gear’s stick tip, and can be lifted 360° on firm, level supporting surface. Capacities are valid for 600 mm wide triple grouser pads. Indicated loads are based on ISO 10567 standard and do not exceed 75 % of tipping or 87 % of hydraulic capacity (indicated via *). Lifting capacity of the excavator is limited by machine stability, hydraulic capacity and maximum permissible load of the load hook. According to European Standard, EN 474-5: In the European Union excavators have to be equipped with an overload warning device, a load diagram and automatic check valves on the hoist cylinders, when they are used for lifting operations which require the use of lifting accessories.

Height Can be slewed through 360° In longitudinal position of undercarriage Max. reach * Limited by hydr. capacity

The lift capacities are stated in metric tonnes (t) on the lifting gear’s stick tip, and can be lifted 360° on firm, level supporting surface. Capacities are valid for 600 mm wide triple grouser pads. Indicated loads are based on ISO 10567 standard and do not exceed 75 % of tipping or 87 % of hydraulic capacity (indicated via *). Lifting capacity of the excavator is limited by machine stability, hydraulic capacity and maximum permissible load of the load hook. According to European Standard, EN 474-5: In the European Union excavators have to be equipped with an overload warning device, a load diagram and automatic check valves on the hoist cylinders, when they are used for lifting operations which require the use of lifting accessories.
