JDN Monorail Hoists are available with air or hydraulic drive for the offshore industry and where heavy loads in reduced spaces have to be moved. Depending on the application Monorail Hoists can be deployed as Double Lifting Gear: working in parallel as for example in BOP handling systems or working in tandem connected by a coupling rod as for example for handling grinding rollers in the cement industry.
