Demag Industrial was one of the earliest German industrial manufacturers which has supplied European manufacturers since 1840.
World renowned for Demag Cranes, and hoists as well as process automation such as plastic extrusion, chemical processing, and industrial stamping.
We are a DEMAG Certified Motor Repair Center.
Mannesmann AG based in Düsseldorf, Germany acquired Demag in 1973, and in 1992 was consolidated under the Demag Mannesmann material Handling AG based in Wetter, Germany.
Cleveland Ohio is home for the North American operations of Demag Cranes & Components which supply all of the state-side requirements for parts, and components for overhead cranes, hoists, and material handling.The company’s product philosophy is based on a proven, modular system approach. Modular components, which are compatible with one another, are combined in various ways to meet individual requirements and to form material handling equipment and machinery that function at the highest levels of efficiency.Demag modular design systems typically are comprised of helical gear motors, offset gear motors, and right-angle gear motors. The Demag component system allows for various brake designs such as basic cylindrical-rotor motors, conical-rotor brake motors, and cylindrical-rotor brake motors.The Demag KB conical-rotor brake motor provides you with a brake motor that utilizes a unique operating principle: The brake is not separately controlled, but firmly connected to the rotor, i.e. integrated. This means that motor start-up and brake release as well as motor switch-off and brake application are each synchronized. Standard applications include:
The Demag KB conical-rotor brake motor features a remarkably simple, robust and reliable brake system. It is an outstanding solution wherever demanding requirements have to be met by the brake.
- Extremely high allowable starts/stops per hour
- High braking energy
- Unaffected by temporary overload
- Long brake lining service life, since the heat generated by the brake is immediately dissipated
- Short overall length, since the brake disc simultaneously forms the motor fan
- No separate control or additional switching elements required, since the brake is automatically applied and released
- No additional motor temperature rise, since a brake coil is not necessary
Demag Z cylindrical-rotor motors:
Demag Z cylindrical-rotor motors are designed for optimum integration with Demag gearboxes and their design configurations to suit your needs. The output ratings of the 2, 4, 6 and 8-pole motors are graded according to the IEC classification. The motors are also available as two speed units or with an integrated flywheel for particularly smooth motions. The housings of motor frame sizes Z63 to Z132 are of high-quality aluminum alloy, guaranteeing high stability for a low deadweight. Motor frame sizes Z160 to Z180 feature a grey cast iron housing.
Demag Microspeed units differ from drives with speed stages and variable-speed drive systems. They represent a combination of two or more brake motors linked by a mechanical gearbox. [The brake of the main motor is designed as a friction coupling, the brake of the creep speed motor acts either direct or via the gearbox of the complete drive.] A number of speeds or whole ranges of speeds can be achieved by using two speed, slip-ring or DC motors and even further Microspeed motors.
Microspeed benefits are:
- Large speed ratios of up to 500 : 1 are possible.
- Precise stopping with creep speed motor for rapid positioning. High repeat positioning accuracy.
- Higher switching frequency compared to two speed motors.
- Creep speed constant and virtually independent of the load.
