Customer benefits at glance
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
