Maintenance Guide for Mechanical and Electric Amusement Rides：Refined management and cycle planning

As the amusement industry continues to elevate safety standards, extensive maintenance can no longer meet the needs of long-term, stable equipment operation. MODERN has developed a refined maintenance system based on operational data from over a thousand pieces of equipment. By scientifically planning maintenance cycles, strictly controlling detailed milestones, and strengthening personnel capabilities, MODERN achieves its goal of "preventive, data-driven" maintenance.

1、 Customizing Maintenance Cycles for Each Equipment: Rejecting a "One-Size-Fits-All" Approach

The operating intensity and structural characteristics of different types of amusement rides vary significantly, requiring tailored maintenance cycles:

High-frequency equipment (such as carousels and trains): Operating for more than 8 hours per day requires a shorter inspection cycle for key components. For example, drive motor bearing temperature should be monitored daily, chain tension adjusted every 3 days, and gearbox oil replaced every 1500 hours (the standard interval is 2000 hours).

High-altitude, heavy-load equipment (such as Ferris wheels and flying chairs): Subject to alternating loads, metal structure inspections require increased frequency. Column verticality should be measured monthly using a total station (the standard is quarterly). Pod connector bolts should be re-tightened every two weeks, and fall arresters should be tested at 1.2 times the rated load every six months.

Water amusement equipment (such as wave machines and lazy river pumps): These are subject to severe moisture corrosion, and electrical system maintenance requires enhanced maintenance. Motor insulation resistance should be tested every 10 days. A dehumidifier should be installed in the control box (maintaining humidity ≤ 60%). Metal parts should be sprayed with a rust inhibitor weekly (use a water-based rust inhibitor to avoid water contamination).

II. Hidden Area Maintenance: Addressing "Invisible Hidden Dangers"

Equipment failures often stem from wear and tear in hidden areas, requiring a dedicated inspection mechanism:

Equipment Foundations and Embedded Parts: Quarterly inspect the concrete foundation for cracks. Use a feeler gauge to measure the gap between the embedded parts and the foundation. If the gap exceeds 5mm, fill it with epoxy mortar. For equipment supported by pile foundations (such as roller coaster pylons), perform a pile integrity test (low-strain method) annually to prevent structural deformation caused by foundation settlement. Internal wiring and seals: Regularly disassemble equipment shields (such as go-kart chassis and bumper car bodies) to check for wear and tear on internal cables and for aging rubber seals at cable holes (replace every two years). Sealing gaskets at hydraulic line joints must be replaced after each disassembly to prevent high-pressure oil leakage.

Sensor blind spot cleaning: Sensors such as speed sensors on bungee jumping machines and position encoders on roller coasters are prone to dust and oil accumulation. Wipe them weekly with anhydrous alcohol to ensure smooth signal transmission. This can be verified by comparing the feedback value from the equipment control system with the actual value; the deviation should be ≤2%. III. Maintenance Material Management: From "Sufficient Stock" to "Used Correctly"
The quality and compatibility of maintenance materials directly impact maintenance effectiveness, necessitating a strict management and control process:

Precise Lubricant Selection: Different components require specialized lubricants—high-temperature grease (temperature resistance ≥ 150°C) for motor bearings, extreme-pressure gear oil (viscosity index ≥ 140) for gear transmissions, and specialized pneumatic oil (containing antioxidant and anti-wear additives) for pneumatic components. Mixing lubricants of different brands or types is prohibited, and oil lines must be thoroughly cleaned between oil changes.

Standardized Stockpiling of Standard Parts: Bolts, nuts, and other standard parts must be stored and categorized by "equipment model + specification." For example, roller coaster track connecting bolts must use grade 8.8 high-strength bolts (with grade 10 nuts) and be labeled with tightening torque values. Stockpiles should be 10%-15% of the total equipment usage. Mechanical properties (tensile strength and yield strength) of the bolts should be verified every six months. Consumable Part Replacement Record Tracking: Establish a "replacement log" for consumable parts (such as brake pads, seals, and oil filters), recording replacement time, batch, supplier, and service life. Data analysis can be used to identify causes of abnormal wear. For example, if a batch of brake pads is found to have a lifespan 30% shorter than the standard, it is necessary to check whether the brake clearance is excessive or whether the material meets the standard.

IV. Personnel Capacity Building: Enabling More Professional Maintenance
The skill level of maintenance personnel is the core guarantee for implementing the plan and must be strengthened through both training and assessment:

Tiered Training System: Basic operator training focuses on daily inspections (such as emergency stop testing and abnormal noise detection), with weekly practical drills. Technical maintenance personnel must master advanced maintenance skills (such as PLC program debugging and gear mesh adjustment) and participate in quarterly specialized training organized by the manufacturer (MODERN offers both online and offline certification courses). Simulated Fault Drills: One to two "fault scenarios" are set up monthly, such as simulated motor overloads and sensor failures, to assess maintenance personnel's response speed and accuracy. The requirement is to locate the cause of the fault within 30 minutes and complete the repair within 1 hour (complex faults can be extended to 2 hours).

Enhanced Safety Awareness: All maintenance work must follow the "Lockout, Tagout, and Operator (LOTO)" procedure, which means disconnecting the power supply and displaying a warning sign after shutdown to prevent accidental restart. For overhead work (such as Ferris wheel cabin maintenance), double-hook safety harnesses are required, and a warning barrier is set up below the work area. 5. Data-Driven Maintenance Optimization

The equipment management system records maintenance data (such as fault type, handling time, and component replacement frequency) and generates quarterly analysis reports:

Identify frequent failure points: If contactor failures in a particular type of equipment exceed 40%, investigate power supply stability or replace contactors with higher-spec contactors.

Optimize maintenance cycles: Adjust cycles based on actual wear data. For example, if a roller coaster's wheels are found to be wearing faster than expected, the inspection cycle could be shortened from monthly to biweekly.

Predictive maintenance: Vibration and temperature sensors are installed on key components (such as the main motor and reducer) to provide early warning of potential failures through data analysis (for example, an abnormally high vibration frequency indicates possible bearing failure).

The core of refined maintenance is "making every operation informed and every component monitored." By customizing cycles, managing details, and strengthening personnel and data utilization, we can reduce equipment failure rates by over 30% while creating a safer environment for guests. MODERN provides customized maintenance manuals based on customer equipment models, helping operators achieve efficient operations and maintenance.
