- Testing and documentation
- Normal cycles, manual operation, protective responses, fire-door procedures and facility records vary by assembly. The proposal can name the demonstrations, measurements and written results included at handover.
- Cause of the failure
- Impact, gradual wear, corrosion, freezing, building movement and a control fault can produce similar symptoms. The verified cause determines whether cleaning, adjustment, component renewal or wider coordination belongs in scope.
- Manual drive components
- Direct push-up operation, a hand-chain hoist or another manual drive has its own chain, wheel, reduction and keeper parts. Wear and accessibility determine the tasks included.
