Demag DC-Com chain hoist range

The Demag DC-Com chain hoist range is available in five sizes, for loads weighing from 80 to 2000 kg.

Enhancements to the range have led to an improved FEM classification. According to the company, this has resulted in a doubling of their service life, since all sizes are classified in the next-highest group of mechanisms according to FEM rule 9.511.

The duty factor has also been increased by 50% for its units as of size 2 (ie, for all types that have a load capacity of 160 kg and higher). There are no restrictions for the duty factor at temperatures up to 45°C. The hoists can also be used at ambient temperatures up to 60°C.

The plug and lift connections enable fast installation and commissioning. All electric connections are plug-and-socket design and chain hoists can be simply attached to a trolley by their folding suspension brackets.

Besides operation with the KBK crane construction kit, the units can also be used on I-beam girders. Manually operated U 11 to U 56 trolleys, as well as electric E trolleys are available for these applications.

All hoist sizes are fitted with an elapsed operating time counter and a diagnostics interface. The low-wearing brake is arranged before the slipping clutch in the drive system and is automatically applied if the control system fails. The cylindrical-rotor motor was developed for operation under arduous conditions.

The operator can adjust the length of the control cable to achieve the correct ergonomic position, which makes it easy to operate the units with DSC or DSC-10 control pendants. The sizes for load capacities up to 1000 kg are of single-fall design, which minimises abrasion of the chain.
