5.2.2 The mounting surface of the anchor bolts shall be higher than the
surrounding ground to avoid corrosion caused by standing water. Make sure
that the bolt exceeds the nut by 2 to 3 times the pitch.
5.2.3 The perpendicularity tolerance of the center line of the tower structure to
the installation datum horizontal plane shall not be greater than 1/1000.
5.2.4 The connection between the guide rail and the tower body shall be firm.
There shall be no jamming during operation.
5.2.5 The height difference of the rail surface of the guide rail at the joint shall
not be more than 1mm, the gap shall not be more than 2mm, and the lateral
displacement shall not be more than 1mm.
5.2.6 The radial clearance between the guide wheel and the guide rail, for the
single rail, shall not be greater than 5mm; for the double rail, shall not be greater
than 10mm.
5.2.7 Non-destructive testing shall be carried out for important shafts (pin shafts)
and important welds. Non-destructive testing methods and requirements are
implemented in accordance with GB/T 34370. Important shaft (pin shaft)
components shall be set with a unique inspection mark when leaving the factory,
and 100% non-destructive testing shall be carried out. Important welds and
important shafts (pin shafts) shall be confirmed by the design organization after
safety evaluation. For the examples of common types of important shafts (pin
shafts) and important welds, see Annex A.
5.2.8 For important shafts (pin shafts), the surface roughness of the mating
surface shall meet the design requirements and shall not be less than 3.2μm.
5.2.9 Dimensional tolerances and geometric tolerances of parts and
components shall meet the requirements of process documents. Unmarked
dimensional tolerances and geometric tolerances of machined parts shall meet
the relevant requirements of GB/T 1804 and GB/T 1184. Unmarked dimensional
tolerances and geometric tolerances of the welded structure shall meet the
relevant requirements of GB/T 19804.
5.2.10 The passenger part shall be stable when starting, lifting, rotating and
stopping. There shall be no abnormal noise and stuck phenomenon during
operation.
5.2.11 For the chains or wire ropes used to suspend the seat, when one of them
is disconnected, the seat shall be able to maintain balance and ensure the
safety of passengers. When necessary, two safety devices shall be installed.
5.2.12 In the hydraulic or pneumatic system, there shall be an overpressure
protection device that does not exceed 1.2 times the rated working pressure.
