Terex Material Handling has launched a new range of rope hoists based on a single design technology. The DMR range is of a modular design and is available with a broad range of complementary components, allowing multiple configurations to meet a wide variety of customer-specific applications. This inherent flexibility allows DMR rope hoists to be manufactured to compact C-design or co-axial design.
The DMR range includes five models with SWLs from 1 to 50 tonnes. They are suitable for conventional cranes and crabs, as well as for stationary applications in the mechanical and plant engineering sectors where lifting, towing, travelling, holding or positioning tasks are required.
DMR modular rope hoists are available as foot mounted hoists, low and standard headroom travelling hoists and double rail crabs to meet specific customer needs. A choice of electrical equipment is available, including the smart Demag SafeControl system, conventional contactor controls or customers’ own control systems. The smart SafeControl system provides a high level of operating safety and reliability, fulfilling requirements for efficient production processes. SafeControl enables many technical features, from by-pass control to tandem operation and load dependent speeds, to be implemented with ease.
The hoist and cross travel drives have two stage or variable speeds, as required. DMR offers a flexible choice of accessories, including cross travel limit switches and current collectors, which may be easily and precisely fitted to the housing in various positions. They may also be adapted when a hoist unit or crab is installed.
The low headroom travelling hoist may be easily converted by the addition of a two wheel “DualDrive” to increase traction for outdoor applications, for example. With this arrangement, the cross travel motor simultaneously drives two wheels via a belt. A predefined mounting position also facilitates the simple installation of a second travel drive “DualDrive Plus”.
The DMR rope hoists satisfy the usual FEM 2m market standard as a minimum requirement and are rated for IP55 protection. The hoist units may be operated via the new D3 generation radio control system or with wire connected controls. Individual parameters, from basic design to the choice of control system, may be selected with a menu driven, online configuration tool. The result is a DMR modular rope hoist that is tailored to meet specific application requirements.
Dr. Thomas Bönker, Senior Director of the Components’ Business Line at Terex Material Handling, explained: “The Demag DMR modular rope hoist makes it easier to select the most suitable hoist unit. Until now, hoist selection depended on the comparison of various options to find the right product for the given requirements. The DMR range offers solutions for all requirements with one basic technology. This means that operators have maximum freedom in the choice of design, control system, drive method and control concept.”
