4 With the award-winning ERC system ERC System More performance, less consumption The principle is simple: As the equipment fitting is lowered, this causes the gas present in the cylinder to be compressed. When the attachment fitting is raised, the energy stored in the gas cylinder provides support for the two lifting cylinders, and less performance is required. 1. Attachment fitting raised / Energy released 2. Lower attachment fitting / Store energy 4. Raise attachment fitting / Release energy Liebherr diesel engine Long life expectancy, expansive cylinder capacity and increased weight According to level IIIA / Tier 3 Specially Developed for construction and industrial machinery operation Oil supply even with 100 % tilt angle Excellent torque 4 A 934 C ERC Litronic Machine for Industrial Applications

5 Performance The A 934 C ERC Litronic has been designed for maximum productivity. Precisely engineered, the Liebherr developed and Liebherr manufactured components including the diesel engine, hydraulic pumps and motors, as well as swing gear and cylinders, guarantee maximum performance. This results in a high lifting capacity with fast working cycles. Innovative solutions Multiple attachments High lifting capacities Quick cycle times Performance without compromise ReGenerationPlus ERC System Liebherr can provide a machine for any material handling application. A straight or angled industrial mono boom can be combined with various industrial sticks and a wide array of attachments to handle any task. The efficient handling of different materials, for example, scrap, wood, sand and gravel or bulk solids, is ensured by the most efficient use of the kinematics of the machine. A separate hydraulic circuit with a maximum hydraulic pressure of 5500psi makes a high swing torque possible. Rapid work cycles are achieved through an independent control system. Maximum performance and maximum forces are available to the operator at all times. The new ReGenerationPlus system on the lifting cylinders saves energy and quickly lowers the attachment. The energy stored by the lowering of the equipment in the ERC System gives the machine up to 107 HP in added performance capacity. This is released again when the equipment is raised, and is also reflected in more powerful and more homogenous work sequences. The result is a clear saving on fuel and, at the same time, even greater performance. 3. Attachment fitting lowered / Energy stored Robust undercarriage The box-type construction of the undercarriage with securely-welded supports provides a solid base, the greatest stability and a long service life in every application An additional dozer blade can be selected 2-range powershift transmission for stepless acceleration Litronic-System Increases productivity of the excavator Reduces fuel consumption Reduces service costs and eases operation Allows maximum sensitivity and as many overlapping movements as are required A 934 C ERC Litronic Machine for Industrial Applications 5

These capacities can be slewed through 360 with the undercarriage in the transverse position. Capacities in the longitudinal position of the undercarriage (+/ 15 ) are specified over the steering axle with the stabilizers raised and over the rigid axle with the stabilizers down. Indicated loads comply with the ISO standard and do not exceed 75 % of tipping or 87 % of hydraulic capacity. The lift capacity values indi cated are attained at the corresponding operating temperature. This operating temperature is ensured by continuous movement of the boom. Weights of fitted working tools (grabs, load hooks, etc.) and load accommodation equipment are to be deducted from the lift capacity values. The lift capacity of the unit is limited by its stability, the lifting capability of the hydraulic elements, or the maximum permissible lifting capacity of the load hook.

These capacities can be slewed through 360 with the undercarriage in the transverse position. Capacities in the longitudinal position of the undercarriage (+/ 15 ) are specified over the steering axle with the stabilizers raised and over the rigid axle with the stabilizers down. Indicated loads comply with the ISO standard and do not exceed 75 % of tipping or 87 % of hydraulic capacity. The lift capacity values indi cated are attained at the corresponding operating temperature. This operating temperature is ensured by continuous movement of the boom. Weights of fitted working tools (grabs, load hooks, etc.) and load accommodation equipment are to be deducted from the lift capacity values. The lift capacity of the unit is limited by its stability, the lifting capability of the hydraulic elements, or the maximum permissible lifting capacity of the load hook.
