Chain Hoist Donati DMK

crane hoist manufacturer

The DMK electric chain hoist from Donati is a machine generally used to lift an unguided load by means of a hook or handling accessories suitable for the purpose. The hoist combined with an electric or manual trolley, which runs on a beam, ensures the integrated handling of lifting and horizontal movements of the load. The electric chain hoist and the trolleys can be fitted on a beam (monorails) or can act as the lifting unit for other machines in which they have been incorporated, such as jib cranes or overhead travelling cranes.
 
Positioned on a beam or at ground level, the electric chain hoist can be used in several different configurations:

Electric chain hoist with hand-push trolley
 
  • Horizontal movement by push/pulling the load
  • Recommended for light duty and short load travel only
  • The push trolley is adjustable for variable flange widths, fitted with steel machined wheels, permanently self-lubricated bearings, fitted with anti tilt derailment bars and equipped with shock-absorbing buffers.
  • Capacities from 125 up to 4000 kgs.
  • FEM (ISO): 2M(M5)
  • Working at one or two lifting speeds
  • Other characteristics as for the DMK in fixed execution

Electric chain hoist with electric trolley
 
  • Movement operated by the push button panel fitted on the hoist
  • Recommended when manual load pushing is not feasible and for heavy-duty use.
  • The electric trolley is adjustable for variable flange widths, fitted with steel machined wheels, permanently self-lubricated bearings, fitted with anti tilt derailment bars to prevent drop or derailing and is equipped with shock-absorbing buffers.
  • The trolley can be supplied with one speed (11 or 22 m/min) or two speeds (7/22 m/min)
  • Electric limit switches to limit the horizontal travel of the electric trolley on the beam
  • Suitable for rectilinear monorails; with special devices it can run on curves (minimum internal radius on the technical catalogue)
  • Capacities from 125 up to 4000 kgs.
  • FEM (ISO): 2M (M5)
  • Other characteristics as for the DMK in fixed execution

 Electric chain hoist with electric trolley - low headroom execution
 
  • The best solution to achieve the maximum hook-run; fitted on a frame with a return system for the chain, the frame is mounted on 2 trolleys.
  • Available in electric or hand-push execution
  • Capacities from 125 up to 4000 kgs.
  • FEM (ISO): 2M(M5)
  • Lifting and travelling at 1 or 2 speeds
  • Other characteristics as for the DMK in fixed execution

Electric chain hoist - climbing execution
 
  • Allows the installation point to be reached with the hook and the related chain, without having to lift the entire weight of the hoist.
  • It is particularly suited for use in the entertainment industry and when frequent installation and dismantling at greater heights is requested.
  • Capacities from 125 up to 2000 kgs.
  • FEM (ISO): 2M (M5)
  • Lifting speed: mt/min. 4 or 8
  • Chain box in cloth
  • Other characteristics as for the DMK in fixed execution
