All inclusive – fully featured with no need for extras

DC-Pro chain hoist

The industry benchmark

With our DC-Pro chain hoist, we meet our own high standards in terms of quality and innovation.The DC-Pro chain hoist is a fully featured, highly versatile chain hoist, which can be installed and put into service in minimum time. Many features that have to be ordered and bought as extras elsewhere are already integrated as standard. The result:

"all inclusive" features at no extra cost
two lifting speeds as standard
improved safety thanks to 24 V contactor control, operating limit switches and elapsed operating time counter as standard
slipping clutch with automatic cut-out by means of speed monitoring
optimum ergonomics and ease of service
main components are maintenance-free for up to 10 years.

Product information

The benefits at a glance

High-performance equipment

"All inclusive" features already as standard
Two lifting speeds as standard
24 V contactor control
Operating limit switches (upper/lower)
Elapsed operating time counter
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

Customer benefits at a 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
