Compact. Versatile. High performance. Demag DVR rope hoist

Compact. Versatile. High performance. The DVR rope hoist DVR offers high efficiency and productivity. Thanks to its comprehensive options, the range includes solutions that can be configured to match a wide variety of crane and lifting requirements. From the standard version to high-performance equipment with smart safety functions, DVR rope hoists satisfy the demands of efficient lifting solutions. High performance Low approach dimensions and reduced C-dimension: DVR hoists have a compact design and low deadweight, providing the best possible utilization of the available space for crane...

Configuration to meet your needs DVR hoist solutions can meet virtually any requirement: asfood-mounted hoist solution as well as for optimized applications on single and double-girder cranes. The range is completed by a basic hoist for plant engineering applications and rotating trolleys. F-DVR: Food-mounted rope hoist • For stationary applications or for special crabs • Can be used in 4 mounting positions, each with one rope lead-off direction • Up to 80 tons EK-DVR: Low-headroom monorail hoist • Optimised design with low headroom dimension for use on cranes and monorails • Very short...

DVR rope hoist: Overview Rope drum/rope drive • Large drum diameter with improved space utilization • Low wear on ropes and return sheaves • Minimum hook travel: Also due to limited inclined pull, loads can be moved and positioned safely and precisely • Easy access to the upper return sheaves and anchorage points • Rope drum encapsulated as standard with powder-coated metal surfaces Rope guide wear on the drum for a longer rope service life • Metal design • The rope is guided reliably and with little Hoist gearbox • Five different transmission ratios • Compact and lightweight design • Quiet...

Overload protection Electric enclosure Travel motor • Reliable mechanical overload • Robust contactor control for • Standard 4:1 ratio • 5/20 m/min (pole-changing) • Optional: With inverter for variable detection • Optional connection to electronical load management I (ELMI) • Optional: force measurement by strain gauge • Optional: Electronical load management (ELMII) with high end monitoring reliable operation also in demanding environments • Standard 3-phase supply: 380-415 V, 50 Hz (440-480 V, 60 Hz) • Metal switchgear cabinet • Easy to service: Hinged doors can be opened without special...

Configured to meet specific application needs A variety of options are available to equip DVR rope hoists to meet given application requirements. DVR units can offer variable-speed drive solutions for lifting and travel motions at different technology levels. The benefits of their inverters are self-evident: • Variable speeds: 1:10, 1:25, ESR 1:37 • Reduced wear: Gentle start-up/lifting reduces the load on the crane system • Longer motor/brake service life • Significant energy savings by up to 50% Load-dependent lifting speed for higher productivity: • High speed without load (up to 100%) •...

Smart Features ...turn your rope hoist into a smart hoist. They enable faster load cycle times, higher productivity and improved safety at the workplace. Anti-sway control Tandem control Prevents increased load sway by active counter-motions of the crane. Active system based on rope angle measurement to detect and dampen any existing load sway. Loads can be safely transported by two DVR rope hoists – via a single control unit. Slack-rope prevention Continuous monitoring of the rope tension: The hoist drive automatically switches off when the load has been lowered to its target position or...
