Product Spotlight – Demag DC-PRO Chain Hoists

The DC-Pro chain hoist is a fully-featured, highly versatile chain hoist, which can be installed and put into service in minimum time. With many built-in features, this hoist has a very high value to price ratio.

High-performance equipment

With this hoist the “extra” features are standard and so are two lifting speeds. With a 24V control, operating limit switches in upper and lower range, an elapsed operating time counter, this hoist has all the premium features built-in.

It also features:

• Aluminium housing components with powder coating,
• Duty factor: 60% (40/20), 360 starts/hour,
• Signals for applications with three motion axes,
• Suitable for tandem operation,
• Comprehensive selection of finely graded load capacities up to 5,000 kg,
• Suspension brackets for improved C dimension (for sizes DC 1–10).

Long service life

• Gearbox, brake and slipping clutch are maintenance-free for up to 10 years (DC-Pro 10–25 brake for up to 5 years),
• Low-wear brake thanks to regenerative braking,
• Brake adjustment is not necessary,
• No load dropping thanks to slipping clutch arranged in front of the brake in the load-bearing arrangement,
• Reduced chain wear thanks to 1/1 reeving for loads up to 1,000 kg,
• Robust cylindrical-rotor motor with fan and separate DC brake,
• No brake bonding thanks to double encapsulated brake.

High operating reliability

• Standard requirements satisfied for functional safety,
• No continuous slipping thanks to slipping clutch with automatic cut-out,
• 24 V contactor control with internal “tri-state” signal transfer,
• Chain hoist and travel drive feature IP 55 enclosure, insulation class F,
• Automatic braking if the control system fails.

Optimum egonomics

• Height-adjustable DSC/DSC-S control pendants with low-fatigue actuation force,
• Control cable length and control pendant position can be adjusted to meet specific needs on site
  (without any need for wiring),
• Pivoting suspension bracket enables the chain hoist to be attached when the trolley has been fitted.

Service-friendly

• “Plug & Lift” and “Plug & Drive” for all electrical connections,
• Elapsed operating time counter, status and error messages shown on display,
• Infrared diagnostic interface with IDAPSY software (to read out and manage specific data),
• Service cover for rapid access to plug connections, strain relief arrangements, collector for 3 m control cable and chain drive,
• Chain lubrication through lubrication opening in the chain guide for improved lubrication between links (sizes DC 1–10).
• Reduced downtimes as chain drive can be replaced without dismantling motor or gearbox parts.

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
