| Unladen vehicle weight |
Approximately 350–550 kg for many two- to four-seat electric golf carts, excluding passengers and cargo. |
Remove passengers and loose cargo. Keep the normal battery pack, standard equipment, fluids, and accessories installed. Weigh the complete vehicle. |
Provides the baseline for calculating payload, transport weight, trailer capacity, and shipping requirements. |
| Battery-pack contribution |
Lead-acid packs commonly add about 180–300 kg; lithium packs are often substantially lighter, commonly about 50–120 kg depending on capacity. |
Use the actual battery-pack mass from the battery label or technical data sheet. Include trays, cables, and mounting hardware where applicable. |
Battery chemistry and location can change total weight, center of gravity, range, braking behavior, and axle loading. |
| Passenger loading allowance |
For planning, use the actual occupant mass. A 75 kg person is a calculation example, not a universal legal limit. |
Passenger load = number of occupants × occupant mass. Calculate front- and rear-seat occupants separately. |
Passenger position affects axle loads even when the total passenger mass remains unchanged. |
| Cargo loading allowance |
Cargo mass varies by use. Golf bags, tools, coolers, and utility loads should be weighed individually when accuracy is important. |
Cargo load = sum of all items. Record whether each item is placed ahead of, between, or behind the axles. |
A small load positioned far behind the rear axle can create a greater rear-axle effect than the same load placed near the center. |
| Gross operating weight |
The correct value is vehicle-specific and must not exceed the lower of the vehicle gross-weight rating, axle ratings, tire ratings, or local legal limit. |
Gross operating weight = unladen vehicle weight + passengers + cargo + permanently installed accessories. |
Determines whether the cart can safely carry the planned occupants and equipment. |
| Recommended weighing equipment |
Two certified platform scales or four wheel scales with a combined capacity above the expected gross weight. |
Use scales with suitable accuracy and verify that all platforms are level, stable, and zeroed before weighing. |
Uneven surfaces, overloaded scales, or different platform heights can produce misleading axle readings. |
| Four-wheel weighing procedure |
Measure front-left, front-right, rear-left, and rear-right wheel loads whenever possible. |
Keep the steering straight, apply the parking brake only if the scale procedure permits it, and ensure every wheel is fully supported at the same height. |
Identifies front/rear imbalance and side-to-side imbalance that a single total-weight measurement cannot show. |
| Axle-load calculation |
Front axle load = front-left wheel load + front-right wheel load. Rear axle load = rear-left wheel load + rear-right wheel load. |
Confirm that front axle load + rear axle load equals the total measured vehicle weight, allowing for scale tolerance. |
Axle limits can be exceeded even when the total vehicle weight appears acceptable. |
| Front/rear weight percentage |
Front percentage = front axle load ÷ total weight × 100. Rear percentage = rear axle load ÷ total weight × 100. |
Use measured axle loads rather than relying on visual estimation. The two percentages should total approximately 100%. |
Shows how loading changes traction, steering feel, braking response, suspension compression, and tire loading. |
| Side-to-side balance |
Side-to-side difference = heavier-side wheel load − lighter-side wheel load. |
Compare left and right wheel readings on the same axle. Investigate persistent differences rather than correcting them with uneven tire pressure. |
Large differences may indicate uneven cargo, battery placement, suspension issues, or a bent component. |
| Center-of-gravity loading effect |
A load located close to the midpoint between axles generally produces a smaller axle-transfer effect than the same load at either extreme. |
For a simplified two-axle calculation: front-load change = cargo mass × distance from cargo center to rear axle ÷ wheelbase. Rear-load change = cargo mass − front-load change. |
Helps estimate axle effects before physically weighing a modified or heavily loaded cart. |
| Worked example: unladen cart |
Total: 480 kg; front axle: 210 kg; rear axle: 270 kg. |
Front distribution = 210 ÷ 480 × 100 = 43.8%. Rear distribution = 270 ÷ 480 × 100 = 56.3%. |
Establishes the baseline distribution before adding occupants or cargo. |
| Worked example: four occupants and cargo |
Starting weight: 480 kg; four occupants at 75 kg each: 300 kg; cargo: 40 kg; loaded total: 820 kg. |
Illustrative measured result after loading: front axle 360 kg and rear axle 460 kg. Front distribution = 43.9%; rear distribution = 56.1%. |
Demonstrates why the loaded condition, rather than the empty condition, should be checked against all ratings. |
| Tire-load verification |
Each tire must be suitable for its actual maximum wheel load at the specified inflation pressure. |
Divide each axle reading between the two tires only when the left/right loads are equal; otherwise use the individual wheel readings. |
Tire capacity is affected by inflation pressure, temperature, speed, condition, and load distribution. |
| Measurement repeatability |
Repeat the weighing at least twice if the result is close to a limit or if readings vary noticeably. |
Zero the scales, reposition the cart, and compare results. Record the date, battery condition, tire pressure, occupants, and cargo arrangement. |
Creates a traceable record for purchasing, fleet management, transport, and maintenance decisions. |
| Global buyer conversion |
1 kg = 2.20462 lb; 1 lb = 0.453592 kg. |
Pounds = kilograms × 2.20462. Kilograms = pounds × 0.453592. Round only after completing the calculation. |
Avoids errors when comparing vehicle specifications, shipping documents, trailer ratings, and local regulations. |
| Safety decision rule |
Do not operate above the lowest applicable limit. |
Compare total weight, front axle load, rear axle load, individual wheel load, tire capacity, suspension capacity, braking capacity, and local legal requirements. |
A compliant total weight does not guarantee compliant axle, wheel, tire, braking, or trailer loading. |
