Site operation in electrical mode
Alternative drive systems and electromobility are among the biggest drivers of the future when it comes to zero emissions construction sites. Ever more stringent regulations relating to air purity from local authorities and the EU are accelerating this trend.
Awareness of more ecologically sound drive systems is also rising in construction machinery – with electrical drive units becoming more and more common on construction sites.
E-mode: Our MK mobile construction cranes can be operated silently with zero emissions on site, and the whole system is very economical and sustainable using a site power supply.
To ensure that they can be operated reliably, MK cranes also have a diesel-powered generator which can be used if necessary – and is also particularly economical as a result of the extremely low power consumption of the drive units.
The MK generates no emissions and no noise if a site power supply is available for it. After travelling to the site, the undercarriage is shut down for crane operations. The high performance frequency converter drive units fitted on these cranes enable you to work in compliance with all the regulations at night or in densely populated areas, in particular. And it also benefits the environment.
Hoisting despite low power supply requirements. If the only available energy source is 32 A, MK mobile construction cranes can still operate properly, thanks to their smart energy management.
When acting as the heart of the site, the MK not only distributes loads, but also power. Connections for outside consumers can be used to power various other construction machines.
Plug in and hoist. Operation using the existing site power supply is particularly simple and economical. No additional costs are incurred for diesel and the time for refuelling is also eliminated.
Simple
A very simple concept – switch on the unit and start work! No modifications required.
As it features a high efficiency 48 kVa diesel-powered generator, the MK can be operated normally even without any infrastructure.
We have even thought about sensitive ears – Just 70 dB (A) outside the prohibited zone makes a very clear point – but does so very quietly.
An average of just 5 litres per hour makes crane operations particularly economical.
A very simple concept – switch on the unit and start work! No modifications required.
Mobile construction cranes generate no emissions and no noise if they are powered by a site power supply. They have an undercarriage with a driving engine to get them to the site and is then simply shut down for crane operations. Hybrid cranes give urban planners, construction planners and architects an opportunity to get control of the wide-ranging requirements and manage environmental problems in urban areas.
We live in a loud world. Noise impacts the recuperation value of where we live and reduces our quality of life – which is why there are so many passionate discussions about it. Minimising noise emissions on urban construction sites and limiting sound are therefore just as important as managing emissions of pollutants.
MK mobile construction cranes from Liebherr feature electric drive units for impressive results at any job – day or night. Silent and zero emissions.
More sites in one day – even more versatile machines. We face up to every challenge.
