Efficiency of Liebherr crawler cranes, duty cycle crawler cranes, piling and drilling rigs Fuel Costs Matter

Efficiency-enhancing engine features A decisive factor for the purchase of a Liebherr machine The newest Liebherr drive and control systems offer several optional features that help to reduce fuel consumption and maximize the reliability and productivity of crawler cranes, duty cycle crawler cranes as well as piling and drilling rigs. Since 2012, Cementation Skanska Ltd. have been operating Liebherr LB series drilling rigs within our multi-functional plant fleet. We have seen high levels of machine utilisation across the UK. The machines (LB 24, LB 28 and LB 36) have been reliable and have performed...

Eco-Silent Mode: With the help of this feature the engine speed is reduced to a predefined, required level. Hence, a notable reduction in diesel consumption can be achieved without any impact on operational output. As a further benefit noise is also reduced by the EcoSilent Mode. Lowering speed of engine while idling: Deep foundation rigs and duty cycle crawler cranes are in idling mode for 45% of their operating time. This figure lies at even 60% for crawler cranes. With the lowering of the engine speed from 950 rpm to 750 rpm while the machine is in idling mode, up to two litres of fuel per hour...

Change of focus? The described features help to increase the efficiency of the machine throughout its whole life cycle. When buying a machine the focus should not only lie on the purchase price. Fuel consumption, longer service intervals as well as a longer service life must also be considered. These aspects are at least as important since they are the main cost factors over the entire lifetime of the machine. Example Consumption Purchase Current focus? A change is required!
