Productivity

The R 9250 is built to outperform all competitors in the medium class mining market. Boasting a 15,00 m³ / 19.6 yd³ bucket capacity in standard conﬁ guration, the R 9250 is the ideal machine to load a ﬂ eet of 100 t dump trucks. Available in both diesel or electric versions, the R 9250 offers the ﬂ exibility to perform many speciﬁ c applications.

Engineered for Intense Mining

Powerful Drive System

The R 9250 is equipped with a Cummins diesel engine which has been speciﬁ cally adapted to withstand the most extreme environments and to reach the highest uptime performance for maximum productivity. The electric drive system provides superior performance when the machine is used in the most speciﬁ c conditions.

Optimized Cycle Times

Rather than using open hydraulic circuit, the R 9250 employs a closed-loop swing circuit to enable maximum swing torque while retaining the full oil ﬂ ow for the working circuit. The independent swing circuit in combination with the powerful drive system leads to fast arm motion, which contributes to faster cycle times.

Precise Machine Motions

The R 9250 design integrates the Litronic Plus electronic control system to allow for easy control even when simultaneous movements are required. The patented Liebherr electronic damping system provides controlled end-cushioning for smooth attachment motions.

High Digging and Lifting Capabilities

High Digging Forces

Power-Oriented Energy Management

Designed for the best mechanical force distribution, the production-tailored attachment delivers high digging and lifting forces. Integrating Liebherr-made cylinders and a wide range of buckets with miningoptimized GET, the R 9250’s attachment ensures the highest forces, easy bucket penetration and high ﬁ ll factor to perform even in the most demanding conditions.

The R 9250’s attachment is equipped with the pressureless boom down function to enable fast cylinder retraction without the need for pump energy. Intelligent energy management diverts the pump ﬂ ow during boom lowering, allowing other cylinder motions to operate unimpeded.

Litronic Plus - Electronic Control

A power management system developed to optimize electrical, mechanical, hydraulic power distribution which encompasses:

• Liebherr designed and built power components

• Continuous monitoring of the engine and electrical system

• Safe, fast and precise control

• Optimum equipment operation

The R 9250’s spacious cab creates a comfortable working environment ensuring peak operator performance, every shift.

Optimized for Maximum Proﬁ tability

Electro-Hydraulic System Efﬁ ciency

Liebherr hydraulic technology in combination with the precision of electronic control contributes to the R 9250’s energy optimization. The high-pressure hydraulic system and the optimized pipe and hose layout maximize usable power transmission. The hydraulic pumps are electronically managed to provide optimal pressure compensation and oil ﬂ ow management. The hydraulic system is independently regulated over the engine circuit for the best operational efﬁ ciency.

Cooling System Efﬁ ciency

The oversized independent oil- and water coolers in combination with low energy consumption fans and on-demand cooling controls enable to maximize available power for digging process.

Optimized Service Intervals

The R 9250’s high pressure hydraulic oil ﬁ ltration systems remove contaminants from the ﬂ uid to offer the highest rate of hydraulic system efﬁ ciency. To maintain the oil quality, all return hydraulic oil ﬂ ow goes through a 15/5 μm ﬁ ne ﬁ ltration system. To promote availability, the grease and fuel tanks are sized to considerably extend the time between service intervals.

Comfortable Cab for Efﬁ cient Work

Superior Operator Comfort

Working Environment Total Control

The large and spacious cab which equips the R 9250 offers ideal working conditions and optimal operator’s comfort. Mounted on silent blocks, the cab design reduces vibrations and limit noise pollution to provide a quiet environment.
