Demag sets crane standards for the future

Standard solutions made by Demag offer outstandingquality, ef ciency, and reliability at the highest level. Everycrane and every crane component re ects decades ofcrane expertise and reliability as a partner for the industry.

Innovation for greater ef ciency to bene tour customersWith the new DR rope hoist, Demag Cranes & Components

has introduced a state-of-the-art standard for craneapplications with loads weighing up to 50 mt and, at thesame time, an entirely new crane philosophy.

The C shape of the Demag DR rope hoist design is ideallysuited to crane applications. Thanks to the many bene tsoffered by the new DR rope hoist, the entire craneoperates much more ef ciently.

Proven crane geometry guarantees high design rigidity,optimum travel characteristics and minimum wearRaised crane girders, designs tailored to match the roof

structure, and compact trolleys with minimum approachdimensions facilitate larger hook paths as well as betterutilization of the available space and reduce initialconstruction and subsequent costsErgonomic pushbutton stations and interactive radiocontrols with load range display ensure highly convenientoperation and safe load handling. The display providescomplete transparency of the system controls

In nitely variable speed control in all motion axes,via frequency inverter-fed drives, reduces load sway,facilitates exact and gentle positioning, and lowers themechanical load on the crane installationHigh lifting and cross travel speeds provide fasterhandling rates and greater ef ciencyStandard overload devices prevent unsafe overloadconditions

EKKE top running single girder cranes provide you withDemag technology at a particularly attractive price. Theyfeature maximum rigidity for a minimum deadweight. Thiskeeps the load on the crane runway low, and acost-effective design can be selected for the building.They also offer the bene ts of outstanding cranegeometry, resulting in exceptional travel characteristics.The Demag EKDR rope hoist is the optimum design for

crane applications, enabling the crane to meet yourrequirements for greater ef ciency.

Top running single girder cranes with beam girder

EKKE top running single girder cranes with beam girdersoffer outstanding value for the money. The use of rolledsteel sections for the crane girder and traveling rope hoistsoptimized for crane applications make these cranes theoptimum solution for lighter loads and shorter spans.

EKKE standard cranes ensure ef cient and fatigue-freeload handling thanks to the higher cross travel speed and

optimized ergonomic control pendants. When ttedwith features such as in nitely variable speed cross traveldrives, they also make it possible to achieve low-swaytravel motions for gentle handling and precise positioningof loads.

In addition, they also offer high reliability and safety aswell as a long service life combined with high levels ofoperating ef ciency by all components.

Under running single girder cranes the column-free alternative

Simply attached to the existing roof structure, Demagunder running cranes eliminate the need for runwaysupport columns. This way, the entire building oor area isavailable for production. Peripheral areas of the workshopcan be served by using the girder overhangs to extendthe travel range of the hoist trolley beyond the runways.Optional latching devices make it possible to transfer thehoist trolley from the crane girder to a branch track and

back without having to deposit the load.

Top running double girder overhead cranes high load capacities combined with long spans

Demag double girder overhead traveling cranes offeryou a virtually unmatched deadweight/load capacityratio. They are also characterized by their outstandingcrane geometry, ensuring extremely favorable travelcharacteristics and therefore minimizing wear. Theparticularly large lifting height is derived from the fact thatthe load hook can be raised between the two cranegirders. Depending on requirements, our double girder

overhead traveling cranes can also be tted with radio oroperator cab controls. Optional maintenance platforms andtrolley platforms not only facilitate crane maintenance butalso ensure that your hall ttings such as lamps, heatingelements or supply lines can be quickly and easily reached.
