| 1. Set the required payload | Separate the intended material payload from the truck’s tare mass and gross vehicle weight. | Typical and maximum load per trip; material density; body volume; loading method; applicable local weight limits. | Payload affects legal road operation, trip count, energy use, tire loading, and vehicle selection. | Rated payload, gross vehicle weight, body capacity, and any stated derating for specific operating conditions. |
| 2. Map the route and duty cycle | Define the complete working cycle, including loaded and empty travel, stops, queuing, and return trips. | One-way distance; daily trips; operating hours; average and peak speed; road surface; stop frequency; seasonal changes. | Energy use depends on the full duty cycle, not distance alone. Frequent stops, rough surfaces, and long idle periods can change consumption. | Vehicle range and energy-consumption estimates under a duty cycle that resembles the planned operation. |
| 3. Record gradients and elevation | Identify the steepest sustained grade, short ramps, and total elevation gain on loaded routes. | Grade in percent; ramp length; elevation profile; loaded direction; road condition; required restart points. | Climbing a grade with a load requires substantial traction and power. Regenerative braking may recover some energy downhill, but recovery varies by conditions. | Gradeability at the intended payload, low-speed climbing performance, thermal limits, and braking capability on descents. |
| 4. Match the battery to the operating day | Determine the usable energy needed between charging opportunities, allowing for operating reserves. | Trips per shift; route energy estimates; ambient temperature; planned charging windows; battery reserve policy. | Battery capacity alone does not establish real-world range. Payload, grade, temperature, driving conditions, and auxiliary loads can all affect energy use. | Usable battery capacity, expected range for the stated duty cycle, charging limits, and battery performance in local temperatures. |
| 5. Plan charging around the shift | Specify where and when charging can take place, including whether charging is available during breaks or between shifts. | Available electrical supply; charger power; connector and charging protocol; parking time; number of vehicles charging at once. | Charging time depends on charger output, vehicle acceptance limits, battery state, and site electrical capacity. | Charging compatibility, estimated charging time for the planned window, installation requirements, and charging support in the destination market. |
| 6. Check the body, chassis, and site conditions | Confirm that the dump body, lifting system, dimensions, and vehicle configuration suit the material and loading site. | Material type and density; body volume; discharge method; clearance limits; turning space; ground conditions; access restrictions. | A suitable payload rating does not guarantee that the vehicle fits the loading, hauling, and tipping conditions of a particular site. | Body configuration, overall dimensions, axle loading, ground clearance, turning characteristics, and compatibility with site procedures. |
| 7. Verify support, safety, and total operating cost | Assess the availability of service, parts, training, and emergency support where the truck will operate. | Local service coverage; parts lead times; warranty terms; technician training; safety requirements; electricity and maintenance costs. | Uptime and operating cost depend on local support as well as the vehicle itself. Requirements for high-voltage work and road approval vary by jurisdiction. | Documented service arrangements, warranty coverage, safety features, regulatory compliance, and cost assumptions over the intended ownership period. |
