JDN Cryogenic Hoists

JDN Cryogenic Hoists The temperature range of JDN Monorail Hoists in standard version is -20°C to +70°C. For a special application at temperatures of minus 45°C, as e.g. the BOP Handling in arctic zones, JDN has developed Hydraulic Monorail Hoists, which meet this demands. To achieve smooth starting of the Hydraulic Monorail Hoists at these extreme temperatures, they are fitted with a preheating device which increases the temperature of the drives to -25°C before operation by means of the standard hydraulic supply.
