 11.3.6 Storage And Discharge Tanks
Examine the discharge tank for corrosion and leaks. Note whether the tank is covered to
prevent entrances of foreign material and is suitably vented to the atmosphere. For
electro-hydraulic elevators, determine whether there is sufficient liquid remaining in the tank
when the lift is at the highest point of its travel to cover the intake and to prevent cavitation.
Means should be provided for indicating the permissible minimum liquid level for equipment.
11.3.7 Operating Valves And Fixtures
Ensure that all operating valves and fixtures are operating in their intended manner and that
all fastenings are in place and secure.
11.3.8 Equipment Location
Pump and control equipment access should be unobstructed by building construction or
debris. Access space should be clean and free minimum 18" clear on 3 sides of unit.
11.4 PERIODIC INSPECTION AND TESTS
11.4.1 Scope
This section describes various operational tests that are recommended to be performed on a
yearly basis. In addition, there are other tests and inspections that should be performed every
three years. It should be specifically documented on the inspector's report that these tests have
been performed and the dates the tests were made.
11.4.2 Flexible Hydraulic Hose And Fitting Assemblies And Flexible Couplings
Examine flexible hose and fittings assemblies, and flexible couplings, as outlined in Section
3. Flexible hydraulic hose and fitting assemblies should be subjected to a test at three times the
working pressure. After six years, they must be replaced; the replacement date should be marked
on the hose.
