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?

There are few possible causes of pneumatic motor malfunctioning:
- Condensate in the airline. Always drain condensate from the line before connecting and starting pneumatically operated equipment.
- Faulty limit switch. Check it, clean/overhaul as necessary.
- Motors needs overhaul due to worn vanes. OVerhaul the motor and replace vanes.
