Checking the load of an electric transfer car is essential to prevent overloading, which can cause equipment damage, safety hazards, or operational failures. Here's a step-by-step guide to proper load checking:
1. Pre-Check Preparation
Review Rated Load: Confirm the transfer car's rated load (marked on the nameplate or manual) before loading. Never exceed this limit.
Inspect Load Distribution Tools: Ensure on-board load sensors (if equipped) are calibrated and functioning. Prepare external tools like floor scales for manual verification if needed.
2. Load Weight Verification
Using On-Board Sensors: For carts with built-in load sensors, check the digital display after loading. Ensure the reading is below the rated load.
Manual Weighing: For carts without sensors, weigh individual items before loading using floor scales, then sum the total weight.
Visual Inspection: Check if the load is evenly distributed on the platform. Avoid concentrated weight on one side, which may exceed local load limits even if total weight is within range.
3. Operational Load Checks
Start-Up Test: After loading, start the cart slowly. Observe for signs of strain, such as slow acceleration, unusual motor noise, or sagging chassis.
Braking Test: Test braking performance with the load. If braking distance increases significantly, the load may be excessive.
Slope Performance (If Applicable): On sloped surfaces, monitor if the cart struggles to climb or maintain speed-this indicates potential overloading.
4. Post-Operation Checks
Inspect Platform & Chassis: After unloading, check for deformation, cracks, or loose bolts on the platform and chassis, which may signal hidden overload damage.
Sensor Calibration: Regularly calibrate load sensors (monthly) to ensure accurate readings.
