5.4 The inspection items, contents, requirements and inspection modes of typical lifting rides-
type amusement devices are shown in Appendix A.
6 Maintenance
6.1 The main maintenance items of the lifting rides-type amusement devices include, but are
not limited to, the following aspects:
a) In accordance with the specified cycles and methods, lubricate passenger restraint
devices, rail guiding systems, lifting systems, drive systems, bearings, important pins,
gears and reduction gearboxes; add or replace lubricants;
b) In accordance with the equipment application and maintenance instructions and the
actual application conditions, replace the hydraulic oil and filter element in the
hydraulic and pneumatic systems;
c) In accordance with the specified pre-tightening force (in accordance with the
corresponding tightening torque), fasten the fasteners, such as: loose bolts and anchor
bolts. Lock nuts, anchor plates, lock washers, cotter pints and positioning rings can
only be used once;
d) Perform de-rusting and re-painting treatment on the rusted parts of steel structures
(rails and tower bodies, etc.), or where the paint has fallen off;

Appendix C
(informative)
Commonly Seen Repair Methods and Requirements for Lifting Rides-type Amusement
Devices
C.1 Chain Repair (replacement)
C.1.1 For the disassembly, replacement and repair of damaged and failed chains, in accordance
with the design drawings, formulate a repair scheme; clarify the procedures and steps of
disassembly and installation, necessary tools and equipment for construction, as well as the
requirements, instruments and measuring tools for post-repair inspection.
C.1.2 During the disassembly, reasonable methods that will not damage other intact parts shall
be adopted. The reassembly shall be carried out in accordance with a reasonable sequence of
the chain structure, so as to prevent incorrect installation of the chains, which may affect the
normal use.
C.1.3 When the chains are assembled in sections on the ground, measures shall be taken to
isolate them from the ground, so as to prevent contamination of the chains. The chains are put
into the chain groove box in sections from the top of a hoist, and slide down to the lower guide
wheel with the assistance of the chains’ own weight or auxiliary external force. After the start
and end of the lifting chain and the return chain are folded together, adjust the slackness degree
of the chains through the tension pulley.
C.2 Weld Defect Repair
C.2.1 The weld defects (such as: columns, tower bodies and cylinder supports) of the lifting
rides-type large-scale amusement devices are repaired by welding, and mainly through the
mode of repair welding, with the purpose of repairing cracks and compensating for wear. The
selection of welding materials, process, inspection and repair shall comply with the design
documents and the stipulations of GB 8408, so as to control the welding quality.
C.2.2 For on-site welding, in accordance with the qualified welding processes and evaluation
reports, the welding process shall be formulated. In addition, the welding shall be performed
strictly in accordance with the welding process. If necessary, welding process specimens shall
be produced on the site and pass the evaluation. On-site welding operation shall not be
performed on the parts where on-site repair welding is not allowed in the design documents.
C.2.3 When one of the following circumstances occurs on the site of welding, corresponding
protection measures shall be taken to satisfy the welding requirements, otherwise, welding shall
not be performed:
a) wind speed: for gas shielded welding, greater than 2 m/s; for other welding methods,
greater than 10 m/s;
