DR-Pro rope hoists

Our DR-Pro rope hoists meet all requirements for state-of-the-art hoists to satisfy tomorrow’s needs. Besides their space-saving design and particularly long service life, they also offer high lifting speeds for faster handling rates. Comprehensive standard features provide excellent value for money.

Available in four basic designs, our DR-Pro rope hoists provide the right solution for virtually any application.

EKDR hoists with a trolley optimised for crane applications feature a compact design and minimum approach dimensions. Low-headroom EZDR double-rail crabs can also be used in applications where space is at a premium and are rated for loads weighing up to 50 tonnes.

FDR foot-mounted hoists are suitable for universal applications and are prepared for direct connection in four mounting positions. The free rope lead-off in all directions provides for versatile application solutions. Further features:

  • higher lifting speed for faster handling
  • high efficiency due to 20% longer service life
  • compact design for optimum utilisation of space.

Benefits

Safety

  • Low-voltage control pendant thanks to 24 V contactor control system
  • Safety-related functions satisfy at least Performance Level c and Category 2 to EN ISO 13849-1
 

Minimum load sway

  • Smooth cross-travel starting and braking motions for low-sway load handling
  • Speeds and acceleration/braking rates can be modified by means of the control pendant, if required
 

Long service life

  • Generously specified gearbox. 2m+ (1,900 hours) for main load capacities and up to 4m (6,300 hours) for demanding applications
  • All sub-assemblies of the chain hoist are rated for a long service life, even under the most demanding conditions
 

Temperature range

  • Reliable operation from -20 °C to +45 °C without any reduction in the duty factor
  • Operation also possible up to 60 °C and more
 

Ergonomics

  • Length of control cable or position of control pendant can be adjusted without the need for any wiring
  • Length of control cable that is not needed can be stored under the service cover
 

High-performance motor

  • Hoist motor has large safety reserves to provide for reliable operation for many years
  • Can be used for switching cycles way beyond usual market levels
 

Pro-Hub function

  • Up to 90% higher rated lifting speed in reduced load range
 

Easy to service

  • Gearbox & slipping clutch maintenance-free for up to 10 years
  • Brake maintenance-free for up to 10 years (up to 5 years for DC 10–25)
  • Simple and rapid maintenance and repair of individual components thanks to the modular chain hoist design – cuts any downtime to a minimum
 

Variable speeds

  • Valuable and sensitive parts can be moved and positioned more smoothly and reliably
  • Variable button characteristic like a car accelerator pedal
 

Status display

  • Display for elapsed operating time counter and operating statuses
  • Always up-to-date for service purposes
 

Slipping clutch monitoring

  • Harmful continuous slipping eliminated thanks to speed monitoring
  • Reliable protection against extreme overload
  • Load securely held in any operating situation and cannot drop while hoist is at standstill, since brake is arranged in front of the slipping clutch in load-bearing arrangement
 

Low noise level

  • Reduced operating noise thanks to helical gearing in all gearbox stages
  • Smooth running characteristics thanks to high-quality gearing
