Chain hoists

Thanks to our expertise and proximity to the customer, we have developed electric chain hoists that can lift almost any type of load with a high degree of safety with fast or individually adapted lifting movements.

Our chain hoists are electrically driven and can be moved electrically or manually by means of trolleys, depending on the application. In addition, a Demag electric chain hoist can of course also be operated in stationary position or on a crane.

High level safety with our electric chain hoists

Thanks to robust and proven electronic control, the electric chain hoists of our DC product line offer improved safety compared to conventional controls. The electric chain hoists satisfy at least Performance Level c and Category 2 to EN ISO 13849-1 for the safety-related functions specified in DIN EN 14492-2.

You can rely on our chain hoists to handle your load. The standard operating limit switches, 24 V contactor control and slipping clutch secure your load in every application.

Certified lifting technology

• DC electric chain hoists satisfy the relevant provisions of
• Machinery Directive 2006/42/EC
• Low Voltage Directive 2006/95/EC
• EMC Directive 2004/108/EC
• BGV standards

Fully featured as standard

A chain hoist always follows a useful overall concept. From crabs and travelling hoist units to the electric trolley to the chain, we always use the highest quality. Many safety features and components that enhance ergonomics are built into our electric chain hoists as standard. We make lifting and lowering your load as smooth, efficient and safe as possible.

Quality for greater efficiency

A gearbox service life that is rated 20% higher according to the FEM classification is a standard feature of many versions of our DC electric chain hoists. This gives you the certainty that the chain hoist service life can be guaranteed for a significantly longer time. In addition, the generous dimensioning of all components ensures the constant availability of the electric chain hoist.

The equipment can be easily put into operation and offers optimum ergonomics thanks to our Plug & Lift and Plug & Drive system. The electrical connections are of plug-in design. Control cable length or position of pendant controller can be flexibly adjusted without the need for any wiring. Ergonomically designed DSC and DSE pendant controllers with low-fatigue actuation force make load handling with our chain hoist as convenient as possible.

The folding suspension bracket also makes it easy to hook the electric chain hoist into the trolley. Infinitely variable adjustment of trolleys to the flange width facilitates fast commissioning.

Demanding application solutions

A DC electric chain hoist can support you in almost any application – also thanks to standardised special solutions. Both in stationary use or fitted with a trolley for use on crane installations, slewing jib cranes or on the KBK light crane system. The combination of several chain hoists can facilitate the handling of a load immensely.

Applications with extended hook centre distance for BigBag load bars are possible with our KLDC travelling hoist for big bags. For travel on curved track, our electric chain hoist mounted on a DDC articulated monorail hoist is the ideal solution. Two or four DC units can be operated in tandem. Double chain hoists that have two mechanically synchronised chain lead-offs are particularly suited for handling long materials and for spreader operation. Our LDC-Q quadro chain hoist helps to handle loads that have a particularly large surface area with four electric chain hoists.

In the wind turbine applications, the DC-Wind offers you hook paths of up to 180 metres with a long service life.

We offer a wide range of load attachments to secure loads to meet the various handling requirements.
