Liebherr is expanding its series of Generation 6 crawler loaders with the addition of the new LR 626 Litronic crawler loader, which is the successor to the LR 624 crawler loader. 

The new LR 626 is successor to the successful LR 624 crawler loader. It was developed and constructed at Liebherr's Telfs plant and has an operating weight of between 16,130 and 18,600 kg. The standard bucket has a capacity of 1.8 m³ and its four-cylinder diesel engine produces an output of 105 kW / 143 HP and complies with Tier 4f emission standards. 

To achieve this, Liebherr has developed its SCR technology to use an injection of AdBlue and a diesel oxidation catalyst. A diesel particulate filter is not required. As a result, the engine operates in a temperature range of maximum efficiency. The constant engine speed, combined with common rail fuel injection, ensures optimised cylinder charging and guarantees lower fuel consumption. 

In common with the larger Liebherr LR 636 crawler loader, the new LR 626 crawler loader has electronic drive control with integrated ECO function. The selectable ECOmode al-lows the driver to lower fuel consumption by reducing the engine speed at the push of a button and still maintain high power. In this way, the ECO control ensures more efficient operation with light to moderately heavy use. Another innovation in all Liebherr Generation 6 crawlers is the proactive power adjust-ment. This involves the constant monitoring of the engine and all other machine param-eters. When required, such as the deflection of the joystick, the engine power is auto-matically temporarily increased according to the current requirements.

In addition to faster response times, this results in a noticeable increase in the perfor-mance capability and pulling power for the machines, both when driving and when load-ing. In order to maximise the conversion of the LR 626’s engine power into performance, optimal weight distribution was an essential part of the design. Thanks to this and the long running gear, the new machine offers an especially high tipping load and therefore an increased loading capacity. 

The hydrostatic travel drive’s compact components allow for a particularly low centre of gravity. Due to the low engine oil sump on Liebherr's diesel engine, this is suitable for gradients of up to 45°. This enables Liebherr crawler loaders to drive on challenging steep slopes safely and efficiently.
