ELECTRIC CHAIN HOISTS

DMK series electric chain hoists, paired with manual or electric trolleys, make it possible to quickly and inexpensively create many standard and special executions.

Thanks to the extreme compactness of the basic components, i.e. the motor and gearbox, they are assembled together in a coaxial line, in order to ensure the maximum use of the hook run and minimum encumbrance of the hoist.

The construction uses the most advanced technologies based on high industrialization production processes and makes it possible to create completely reliable and technically innovative machines through economies of scale.

The high-quality level is guaranteed and controlled by the company quality system certified according to the standard EN ISO9001: 2008

 

PROTECTION AND INSULATION OF ELECTRICAL PARTS

  • Self-braking In the lifting and travelling motors; IP55 protection – “F” insulation class
  • DMK 2-3-4 brake: IP23
  • Limit switch: IP65 minimum protection – 500 V maximum insulation voltage
  • Cables: IEC 20/22 II 450/750 V maximum insulation voltage
  • Non-standard protections and insulations are available upon request.

 

ELECTRICAL POWER SUPPLY

  • Standard DMK electric chain hoists are designed to be powered with AC current with the following voltage:
    • three phase of 400 V - 50Hz. according to IEC 38-1
    • single phase of 230 V +/- 5% - 50 Hz. (for DMK 1-2-3 hoists at one speed and capacity up to 800 kg)
  • Non-standard voltages and frequencies are available upon request.

 

NOMINAL USE CONDITIONS IN THE STANDARD EXECUTION

  • Operating temperature: minimum -10°C; maximum +40°C
  • Maximum relative humidity: 80%
  • Maximum altitude 1000 m above sea level
  • The machine must be installed indoors, in a well- ventilated place, free from corrosive fumes (acid fumes, saline mist, etc.)

 

NOISE LEVEL

  • The sound pressure level emitted by the hoist when fully loaded is always less than 85 dB (A). The incidence of environmental characteristics such as the transmission of sound through metallic structures, reflection caused by combined machines and walls, is not included in the indicated level.

 

REGULATIONS COMPLIANCE

DMK electric chain hoists and their trolleys are designed and manufactured according to the “Essential Safety Requirements” of Annex I of Machinery Directive 2006/42/EC and are placed on the market equipped with the CE mark and CE Declaration of Conformity - Annex II A.

In addition DMK electric chain hoists and their trolleys are in compliance with the following directives:

  • LOW VOLTAGE DIRECTIVE 2014/35/UE
  • ELECTROMAGNETIC COMPATIBILITY DIRECTIVE 2014/30/UE

 

DMK series electric chain hoists and their trolleys are also available with CSA homologation, upon request.
