Related applications

Construction

Space is limited on construction sites, and there are people working everywhere. Contractors need machines that can safely maneuver in a tight spot. At the same time they still need to be powerful enough to get the job done. At Danfoss, we deliver the components, software, and controls that enable your machines to run safely, efficiently and effectively.
Crane and material handling

Cranes and other large handling machines are required to operate within very specific load ranges. Danfoss provides pressure transmitters that supply load limiting systems with crucial data, safeguarding your equipment, your load, and your operator.
Forestry

Rough, sloping terrain and cramped working conditions call for robust and reliable forestry machines. We make sure you can manage everything from cutting trees and transport to preparing the forest floor for replanting. We have the smart hydraulic solutions your machines need for precise and efficient forestry operations.
Heavy machinery

Think about the heaviest challenges in the open mining, road building and construction industry. Tasks such as cutting through rock or the Arctic permafrost; compacting thick layers of hot asphalt. As well as lifting huge, prefabricated wall panels into place.
Lawn and turf

Lawn and turf machines must adapt to their surroundings and the season – becoming sweepers or snow blowers as required. At Danfoss, we make hydraulic solutions to provide that flexibility and ensure safe and efficient operation.
Road building

Advanced hydraulic systems from Danfoss deliver the machine performance that ensures road builders can meet their deadlines.
