Demag DMR Rope Hoist

One rope hoist. Two designs. Many possibilities.

Individual needs require specific solutions. That is why we developed the Demag DMR modular rope hoist. You can benefit from ground-breaking flexibility in all types of applications: from stationary installations to crane systems. For the first time, a rope hoist can be built either in a C-design or co-axial design utilising one basic technology. The extraordinary wide range of possible DMR applications can be extended thanks to smart interfaces and corresponding fittings and accessories.

Choose for yourself:

  • C-design or co-axial design
  • Five sizes with load capacities up to 50 tons
  • Various application types: foot-mounted hoist, low-headroom travelling hoist, double-rail crab and standard-headroom travelling hoist
  • Control system: smart SafeControl system, conventional contactor control or provided by the customer
  • Variable or two-stage switching elements
  • Control concept: wired connection or radio control

Benefits at a Glance.

High variability thanks to modular design

  • Modular design for rope hoist configuration to meet individual needs
  • Broader range of applications with one basic technology
  • More sizes with higher load capacities

Two designs for all requirements

  • C-design: optimised for crane applications with compact overall dimensions and reduced approach dimensions
  • Co-axial design: versatile integration into virtually any construction, optional mechanical microspeed unit for even greater precision

Planning and application flexibility

  • Application types: foot-mounted hoist, low-headroom monorail hoist, double-rail crab, standard-headroom monorail hoist
  • Smart interfaces for many freely selectable fittings and accessories
  • High operating safety and reliability thanks to smart Demag SafeControl system
  • Alternatively: contactor control or control system provided by the customer

Further benefits

  • Rugged and reliable mechanical components
  • High traction with double-wheel drive (DualDrive), optionally with a second travel motor (DualDrive Plus) for EK-DMR
  • F10 mechanical microspeed for co-axial design: two separate conical-rotor motors for main and creep lifting motions for even more precise load positioning
  • Remote diagnostics in real time with Demag StatusControl

 

Susanna Schneeberger leads worldwide activities of Terex Material Handling.

With effect from March 16, Susanna Schneeberger leads the Terex Material Handling business group. She follows Steve Filipov, who is responsible for the entire Terex Material Handling & Port Solutions segment and was leading the unit on an interim basis.

Steve Filipov says: “We are very happy to have found an outstanding leader in Mrs Schneeberger. She brings strong commercial and business strategy expertise to Terex and a track record of profitably growing global businesses.”

Mrs Schneeberger explains her motivation to take over the worldwide leadership of Terex Material Handling: “Terex is a great company and Demag is a very well-known global brand in which I see a lot of potential and want to continue to develop based on its current strengths and success. The global footprint, the strong and innovative product portfolio and the excellent service offering were further aspects that were crucial to me.”

Until now, Mrs Schneeberger had been working for Trelleborg AB, a Swedish-based company and leader in industrial engineered products and solutions. For the last eight years, she led Strategic Business Development for the group and Global Sales & Marketing for Trelleborg’s Industrial Solutions business area.

Prior to Trelleborg, she worked in Germany for ten years and has had leading Strategy, Business Development and Commercial roles for IXOS/Open Text Corporation, IconMedialab AG, and IMP/Meister Verlag AG.

Susanna Schneeberger holds Masters degrees in International Business and European Affairs from Lund University, Sweden. She is fluent in Swedish, German and English. She is moving to the region with her family: “I have throughout my whole career worked internationally and lived and worked abroad for twelve years, ten of which were in Germany. It is great to be back in Germany, it really feels like my second home.”

Overhead material transport.

The aviation industry supplier Premium Aerotec relies on two Demag V-type cranes from Terex Material Handling for manufacturing and transporting aluminium skin panels that are used for aircraft fuselage segments. The low crane deadweight reduces loads on the building structure and provides even more scope for handling loads.

At the plant at its location in Nordenham (Lower Saxony), Premium Aerotec produces aluminium skin panels, which form the basis for the subsequent fuselage sections. These panels are first placed in autoclave moulds. Stringers are then bonded to them and a vacuum film is applied. This is then followed by a bonding process, which takes place in special pressure-tight kilns, which are called autoclaves.

First choice: cranes

Premium Aerotec utilises a crane as an overhead handling device to lift the individual component carriers with the fuselage sections into the autoclaves, and to transport them to an ultrasonic test facility after the bonding process. Until now, these tasks were performed by a double-girder overhead travelling crane that had box-section girders and was equipped with four 1.1 t hoist units. “Since the loads that this crane had to lift several times every day weighed around 4.1 tons, we were always working close to the limit”, explains Andreas Voge, who is responsible for assembly system factory planning at Premium Aerotec.

Planning for a new investment became more specific when the double-girder overhead travelling crane, which dates back to 1961, came up for refurbishment. To make the production processes more flexible, Premium Aerotec planned to invest in two single-girder overhead travelling cranes that can operate separately, as well as in tandem.

Due to the load-bearing capacity of the building structure, the two new cranes were not allowed to exceed the deadweight of the existing crane and, therefore, their wheel loads were not to be any higher.

Impressive crane concept

The Demag V-type crane satisfied all of the conditions – particularly in view of its reduced deadweight. This enabled the rated load capacity to be increased by a few hundred kilograms and the owner was better prepared to meet future developments.

Manufacturing aircraft components with V-type cranes

At its production plant in Nordenham, Premium Aerotec now operates two Demag V-type cranes that have spans of 24 m and are each equipped with two Demag DR-Pro 1.5 t rope hoists. Andreas Voge, who is responsible for assembly system factory planning at Premium Aerotec, reports: “By using two cranes, we have gained more flexibility. The cranes can also perform various transport tasks along the 115 m-long crane runway. However, they are still mainly used to serve the autoclaves. To do this, both cranes work in tandem and the four hoist units operate under synchronised control.”

Fred Maas, who co-ordinates materials handling equipment supplied by external vendors at Premium Aerotec adds: “Thanks to the V-type crane’s reduced oscillation characteristics, the jigs can be picked up and deposited in a more controlled way. Simple switch-over to tandem operation as well as the possibility to position components gently and carefully resulted in swift acceptance of the new cranes by our crane operators.”

Reduced effort, improved safety

A further aspect of the Demag V-type crane was essential for Premium Aerotec: safety during regular operation. Fred Maas explains: “This new type of crane offers another benefit: thanks to its V-type structure and vertical struts, the weld seams can be checked at a glance. The regular visual inspections can be completed within a quarter of an hour.”
