Demag has released the latest version of the DC-Com chain hoist range designed for longer service life, simple installation and commissioning, and reliable operation at higher ambient temperatures.

The improvements in the latest release of Demag DC-Com chain hoists have led to a new FEM classification, resulting in a doubling of their service life, since all five sizes are now classified in the next highest group of mechanisms according to FEM rule 9.511. 

The duty factor has been increased by 50% for units of size 2, i.e. for all types that have a load capacity of 160kg and higher. These characteristics also apply to applications in higher ambient temperatures. There are no restrictions for the duty factor at temperatures up to 45°C; Demag DC-Com chain hoists can also be used at ambient temperatures up to 60°C, offering customers even more benefits.

The latest Demag DC-Com chain hoists retain all the attributes of the proven range such as the high quality of manufacture, rugged design and simple operation. Fast installation and commissioning thanks to the plug and lift connections are still a characteristic of Demag DC chain hoists; all electric connections are of plug-and-socket design and the chain hoists can be simply attached to a trolley by their folding suspension brackets. 

In addition to the KBK crane construction kit, DC-Com units can also be used on I-beam girders. Manually operated U 11 to U 56 trolleys as well as electric E trolleys, which provide for smooth chain hoist starting and stopping travel motions, are available for these applications.

Key features of Demag DC-Com chain hoists include an elapsed operating time counter and a diagnostics interface provided as standard; low-wearing brake providing for very safe operation; highly durable gearbox minimising any service work and maintenance-free for up to 10 years; and Demag cylindrical-rotor motor, equipped with a fan and a separate DC brake, and developed for operation under harsh conditions.

The operator can adjust the length of the control cable to achieve the correct ergonomic position, which makes it easy to operate DC-Com units with DSC or DSC 10-C control pendants. The sizes for load capacities up to 1,000kg are of single-fall design, which minimises abrasion of the chain.

DC-Pro chain hoists are available for users who have even higher requirements in terms of FEM classification and chain hoist performance. The DCS-Pro variant, which is fitted with a variable-speed drive, offers convenient handling and highly precise positioning of loads.
