Can not lift gangway

Our pneumatically operated gangway davit is unable to lift the gangway into its storage position. We had to use a manual handle.

Why may the davit fail?

Answer:

There are few possible causes of pneumatic motor malfunctioning:

  1. Condensate in the airline. Always drain condensate from the line before connecting and starting pneumatically operated equipment.
  2. Faulty limit switch. Check it, clean/overhaul as necessary.
  3. Motors needs overhaul due to worn vanes. OVerhaul the motor and replace vanes.
