Appendix C
Commonly Seen Repair Methods and Requirements for Track Rides-type
Amusement Devices
C.1 Welding Repair of Steel Structure
C.1.1 The tracks and columns of the track 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.1.2 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.1.3 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;
b) relative humidity: greater than 90%;
c) rain and snow environment;
d) Weldment temperature is lower than -10 C.
C.1.4 For long-distance welding (above 20 m) on the construction site, the length of cable
extension shall be compatible with the cable diameter (cross-sectional area); the cables cannot
be used in coils during operation. Before welding, the welding machine shall be debugged to
ensure that the output voltage of the welding cable is consistent with the value displayed on the
voltmeter of the welding machine.
C.1.5 The welding process shall have welding records. After welding, in accordance with the
requirements of the design documents and relevant standards, conduct non-destructive testing
or tests to ensure that the welding quality complies with the requirements.
C.2 Wheel Axle Repair
C.2.1 Before repairing the wheel axle, 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, requirements for post-repair inspection, and instruments and
measuring tools, etc.
C.2.2 In accordance with the installation process documents, hoist the vehicles. The track rides-
type vehicles are generally installed in the sequence of carriages from the end of the track in
the maintenance section.
C.2.3 After disassembly, if the axle is found to be corroded, several worn, deformed or broken,
it shall be replaced.
C.2.4 After reassembly, the axle steering mechanism of the vehicle shall be flexible and reliable;
there shall be no jamming. The vehicle coupler shall be safe and reliable, and the rotation shall
be flexible. The wheel device shall be flexible; the tire pressure shall be moderate.
C.3 Track Repair
C.3.1 For severely worn, deformed or broken tracks, they shall be replaced and re-installed.
The track installation shall comply with the design documents and the stipulations of relevant
C.3.2 The hoisting process shall ensure that the tracks are stable and docked in place. The track
joints shall be smoothly transitioned. The height difference at the joint of the contact surface
between the track and the wheel shall not be greater than 1 mm, and shall be gradually polished
and smoothed at least 150 times the length of the deviation.
C.3.3 The allowable error of the track gauge shall comply with the design requirements. Before
track hoisting, 10% spot check shall be performed to re-measure the track gauge, and the pass
rate is required to be 100%. Once disqualified parts are found, complete re-inspection shall be
conducted, and the inspection results shall be fed back to the manufacturing organization. If
necessary, on-site correction shall be performed.
C.3.4 The transition of tracks with different curvature radiuses shall be smooth, so as to ensure
the smooth operation of the vehicle.
C.4 Others
For other mechanical parts and electrical equipment that need to be repaired for health recovery
due to wear, tear, deformation, fatigue and corrosion, a specific repair scheme shall be
formulated. Repair shall be carried out in accordance with the specified process through
disassembly of equipment parts, replacement of damaged parts (including electrical control and
safety devices), assembly and system debugging.
