Specialized Lifting Systems for Large Capacity Loads offshore, Underground, Anywhere

From 10ton to 100ton Capacity

Air Pressure 85 PSI (6 bar)

Specialized Lifting Systems for Large Capacity Loads Offshore, Underground, Anywhere

From 10 Ton to 100 Ton Capacity,
Air Pressure 85 PSI (6 bar)

Monorail Hoists EH are special high capacity lifting systems designed to handle heavy loads over monorail systems. Because of the trolley wheel design, they can be used on standard I-beams either with tapered or parallel flanges, or on special fabricated beams. JDN Monorail Hoists are especially suited for applications in high humidity, dust or hazardous environments with a high risk of explosion.


Features:

  • Explosion-Proof
  • Low headroom
  • Small size relative to capacity
  • Little air consumption
  • High performance multi-vane motor with self-lubricating features and positive start-up system for a smooth start and consistent operation
  • Trolleys with anti-drop and anti-climb devices
  • All-steel cast iron construction
  • Silencer for low noise operation

Options:

  • Spark-resistant package
  • Rack and pinion drive
  • Offshore paint
  • Delta-P overload protection

Applications:

  • Power generation -Turbine, generator maintenance
  • Cement industry - Roller pair handling in roller mills.
  • Offshore oil industry - Riser / pipe handling in riser bridge cranes; service units in generator stations.
  • Foundries - Hoisting systems in high capacity foundry cranes.
  • Pipelines - Valve replacement in pipeline pump stations.
  • Chemical industry - Handling of reactor sections.
