Mobile Cranes with maximum flexibility

Thanks to their mobile undercarriage supported on wheel or chain travel gear, Mobile Cranes are indispensable today for the construction industry, heavy-duty transportation, or as emergency and rescue vehicles. Wherever heavy loads, great heights or physically confined working environments must be mastered, products from Hartmann & König are the pivotal points for the supply of energy to bracket arms, grabs or machinery superstructures.

In particular, spring cable reels, hose reels and slip ring assemblies ensure the high functional availability of Mobile Cranes. They transfer power and data flows as well as other media continuously and reliably. Alternative solutions to today‘s fuel-intensive use of diesel-powered machines, such as excavators and loading machines, are considered a key technology in the context of the efficient use of renewable energy.

For many years, Hartmann & König has supplied systems tailored to customer requirements for the electrification of mobile excavators with the help of spiral or cylindrical winding motorised cable reels. This electrification is particularly profitable on machines that have a predictably limited scope of movement.

Motorised cable reels by Hartmann & König are an eco-friendly solution for travel ranges of up to 1,000 m and they help reduce costs in the long run. Thanks to significant savings in terms of fuel consumption, maintenance and downtimes, the investment costs for a high-quality power supply with motorised cable reels usually pay back very quickly for the customer.
