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.

JDN Cryogenic Hoists

Not only for the BOP Handling under arctic conditions

The JDN Hydraulic Monorail Hoists are suitable for operation with cryogenic hydraulic oil and work efficiently in a temperature range from -45°C to +40°C.

Advantages

• Temperature range -45° C up to +40° C
• Hydraulic drives
• Smooth starting of the drives due to preheating device
• Operation with cryogenic hydraulic oil
• Tested under real conditions and in operation in Siberia
