Variable speed electric chain hoist
DCS-Pro series
Demag Cranes & Components
The benefits of Demag chain hoists with infinitely-variable speed control will also impress you: high-quality, sensitive parts can be lifted, lowered and positioned more gently and carefully.
Installation and positioning processes can be controlled with greater precision, hoist motions can be performed much more quickly thanks to an almost doubled nominal lifting speed in the partial load range. The new variable-speed DCS-Pro and DCMS-Pro chain hoists represent high efficiency and safety. The control unit and the frequency inverter are integrated beneath the electrical equipment cover as a compact plug-in modular sub-assembly to save space.
In comparison with the proven DC-Pro with two hoist speeds, the new Demag DCS-Pro and DCMS-Pro chain hoists offer your further benefits:
* Infinitely variable speed control for lifting and lowering motions over the entire load range
* Creep lifting speed from 0.15 m/min (DCS 1 and 2) and 0.08 m/min (DCS 5)
* Gentle starting and precise positioning thanks to particularly fine control at low speeds
* Gentle positioning and fast travel in one, thanks to a 1:200 control ratio
* Pro-Hub: Up to 90 % higher nominal speed for partial load or no-load operations
* Automatic switchover to creep lifting speed before the upper / lower stopping positions are reached
* Smooth operation and optimum ergonomics thanks to 10 mm switching path and progressive characteristic of the PWM switching elements
* Acceleration and braking ramps prevent significant load sway
