​DH Rope Hoist

The Demag DH rope hoist units can be used in a wide variety of applications, both as a travelling hoist on cranes or monorails and as stationary solutions. 

They offer a number of special technical features that enable loads to be handled reliably also for demanding requirements. 

Conical-rotor brake motors in combination with mechanical microspeed units facilitate particularly high numbers of starts/stops and duty factors. 

In combination with tried-and-tested contactor control, DH hoist units ensure reliable operation also in harsh environments with high ambient temperatures, high dust levels and aggressive atmospheres. 
​
Other features include:

• three sizes with load capacities up to 100 tonnes
• hook paths up to 104 m
• highly precise positioning with mechanical microspeed
• rope lead-off possible in any direction
• torsionally rigid frame open on all sides – for bolted connection on all sides.
  
  

Special technical features to meet demanding operating requirements:

• high number of starts/stops and high duty factor thanks to mechanical microspeed and conical-rotor brake motors; also for high ambient temperatures
• highly precise positioning with mechanical microspeed
• three sizes with load capacities up to 100 tonnes
• hook path up to 104 m
• various rope drum designs available: one, two, four, six and eight grooves
• limit positions reliably monitored by precision limit switches that are driven direct by the drum
• tried-and-tested contactor control for reliable operation in arduous environments
• space-saving planetary gearbox arrangement: protected inside the drum
• high safety levels and long service life thanks to load distribution in the planetary gearbox.
