Compensation

Why compensating ropes and chains in elevators?

  • Reduced energy saving, because the compensation ropes and chains, functioning as counterweight, adjust the weight of large parts of the ropes.
  • Gentle starting up and brake of the car
  • Optimal traction capability particularly for high shafts

 

Application of the compensating chains
 

Meaningful as from 1 m/s till max. 3.5 m/s (according to relevant norm) for low, mid und high rise applications:

  • DRAKO comfortBalance
    fully extruded with better running smoothness
  • DRAKO widerloopChain
    fully extruded with better running smoothness and a distinct wider loop diameter
  • Accessories for ideal mounting

 

Application of the compensating ropes
 

  • Mainly for installations of 2.5 m/s and upwards with tensioning device (according to EN 81-1 a jump-safety function of the tension roller as from 3.5 m/s is required)
  • Solution: DRAKO 180B / DRAKO 200B
  • Advantage:
    • High Flexibility through special construction
    • Less elongation through special synthetic cores
    • Special lubrication for longer service life and larger maintenance intervals

  

Special Compensating Ropes

Special compensating ropes (balance ropes), to be used in tensioned application only. The rope construction varies with the nominal diameter to optimize the performance.
