Demag DC-II chain hoist

The industry benchmark. Second generation.

Quality. Performance. Demag DC-II chain hoist.

The Demag DC-II chain hoist meets high standards of quality and innovation. With its second generation, Demag is consistently following the DC path and once again defining the industry benchmark. Naturally made in Wetter.

Innovation from Wetter.

Like its predecessor, the DC-II offers the most comprehensive standard equipment and also a wide-ranging option package, which underscores the flexible application possibilities of the hoist and its modular design.

The high-quality components of the chain hoist meet all the demands of 'made by Demag' quality. In-house gearbox production and assembly at the main plant in Wetter epitomise the expertise that has established the DC as an industry benchmark.

Second generation. Fully equipped instead of a list of extras.

The main components of the DC-II are maintenance-free for up to ten years. Easy adjustment options without the need for special tools and the Plug&Lift principle characterise the service-friendliness of this hoist.

Safety during operation is underlined by the slipping clutch with automatic cut-off through speed monitoring. In addition, 24 V contactor control, operating limit switches and elapsed operating time counter ensure safe operation with the DC-II.

Demag DC-II chain hoist

From its inception, the DC-II is available in pre-configured variants with load capacities from 125 to 1,000 kg direct from stock. The basic DC-Com II variant and the high-end DC-Pro II variant differ in terms of their classification in the FEM / ISO group of mechanisms and their lifting speeds. Both variants of the DC-II have the same high level of equipment.

Immediately available

With the market launch, Demag is offering three sizes (DC-II 1/2, DC-II 5 and DC-II 10) as pre-assembled chain hoists. The benefits for you are fast availability and perfect harmonisation of the tried-and-tested components. These chain hoists, which are available direct from stock, feature safe, low-wear and ergonomic 1/1 reeving. With the 2m to 4m groups of mechanisms, they can achieve up to 6,300 hours of service.

Your lifting heights

DC-Pro II 5 metres
DC-Com II 4 metres

With the two speed settings, you can select a high operating speed with the powerful V2 and a sensitive positioning speed with V1.

The transition of the existing chain hoist range to the new generation is ongoing. Once it is complete, the entire DC chain hoist range will be available in the new DC-II generation.

Quality down to the last detail

As soon as Demag lettering adorns the cover, the product stands for quality. Demag DC-II chain hoists consist of high-quality assemblies and components that are designed for harsh conditions and long-term service. Essential components such as the gearbox, brake and slipping clutch are maintenance-free for up to 10 years.

Group of mechanisms to FEM / ISO

Hoist units are classified according to FEM/ISO in accordance with DIN EN 14492-2 and are calculated on the basis of the average of the operating time, the load on the hoist unit and the lifting distances travelled per day. The result is the maximum service life of the hoist unit under full load.

FEM / ISO	Operating hours
1Am / M4	800
2m / M5	1,600
2m+ / M5+	1,920 (Service life 20%)
3m / M6	3,200
4m / M7	6,300
