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
