How Do You Install the Big Wheel for UIPM Modern Pentathlon? TourGo’s Step-by-Step Guide
As modern pentathlon enters a new era following the Paris 2024 Olympics, the obstacle discipline has become the centerpiece of the sport’s evolution.
As a UIPM-certified obstacle course supplier, TourGo is committed to providing event organizers worldwide with competition-grade equipment that meets the highest international standards. Among the eight standard UIPM obstacles, Obstacle #2 – the Big Wheel stands out as one of the most technically demanding and visually striking elements on the course. It often separates elite athletes from the rest.
To help national federations, event hosts, and training centers build standard-compliant courses efficiently and safely, TourGo is proud to release the official Step-by-Step Installation & Calibration Guide for the UIPM Obstacle #2 Big Wheel.
Below is a practical walkthrough based on the UIPM Technical Manual – designed to help you conquer this iconic obstacle.
Why the Big Wheel Is the Backbone of Your Course
The Big Wheel tests an athlete’s upper body strength, core stability, and dynamic coordination. According to UIPM competition rules, athletes must jump from the previous platform, grab the rolling wheel rim, swing across using momentum, and land on the opposite platform – all without touching the ground.
A poorly installed Big Wheel (e.g., excessive wobble or incorrect dimensions) not only compromises athlete performance but also creates serious safety risks. That’s why following TourGo’s standard procedure is essential.
TourGo Step-by-Step Installation Guide
Before you begin: Ensure you have a standard tool kit and installers.
Step 1: Foundation Positioning & Pre-Assembly
- Course Layout: According to the UIPM total course length of 60m–70m, determine the exact position of Obstacle #2. Ensure it aligns centrally with the preceding and following platforms, with precise spacing between them.
- Frame Assembly: TourGo’s Big Wheel features a high-strength 6082 T6 aviation-grade aluminum structure – lightweight yet load-bearing. Connect both support columns to the base plates. Important: All bolts are designed with anti-loosening features. Do not fully tighten them initially – leave room for fine-tuning.
Step 2: Core Component – Big Wheel Suspension
This is the most critical step. The Big Wheel has a rim diameter of 160cm, and its lowest point must be strictly controlled at a height of 230cm (±5cm) above the ground.
- Suspension Adjustment: Secure the wheel axle precisely through the hub center. Use a spirit level to verify that the wheel’s rotation plane is perfectly perpendicular to the direction of the course.
- Dynamic Testing: After installation, manually spin the wheel to check for smooth rotation and any abnormal metal friction sounds. TourGo’s specially engineered bearings ensure sensitive rim response even during high-velocity grabs.
Step 3: Safety Padding & Impact Absorption Systems
UIPM regulations mandate that safety mats must be placed under and around all obstacles.
- Landing Zone Treatment: Directly beneath the Big Wheel and extending 100cm to both sides, you must install high-density impact-absorbing mats (RG25) with a minimum thickness of 20cm.
- Anti-Slip Surfaces: The athlete’s takeoff and landing platforms must be covered with 2cm thick low-profile anti-slip mats to ensure excellent traction even in wet or humid conditions.
Step 4: Final Inspection & Load Testing
Use a torque wrench to perform final tightening on all connection points. Based on TourGo’s field experience, you must conduct dynamic load testing simulating an 80kg athlete (e.g., hanging and swinging) to check for structural deformation or abnormal sounds.
