Dump Truck Hire in Kenya: How to Calculate Fleet Size for Your Earthworks Project
The Complete Fleet Sizing Formula for Earthworks Haulage — Stop Overpaying for Idle Trucks or Watching Your Schedule Slip.
The most expensive mistake in earthworks is not the excavator you choose — it is the trucks you fail to size correctly. Hire too few dump trucks, and your excavator sits idle for half the day, burning fuel and operator wages while waiting for the next haul cycle. Hire too many, and you are paying for trucks that queue at the dumping site, adding unnecessary cost to every cubic meter moved.
In Kenya's earthworks market, three tipper truck types dominate: the 18-ton Tata LPK 2518 (the workhorse of county roads and small sites), the 25–30-ton Howo and Fuso range (the standard for commercial bulk earthworks), and the 35-ton+ heavy haulers (for mega projects and long-distance haulage). Each has a specific role, and matching the right truck to your excavator, haul distance, and material type is a calculation — not a guess.
This guide gives you the exact formula to calculate your dump truck fleet size. Whether you are stripping 10,000 m³ of topsoil in Kiambu, hauling murram for a county road in Machakos, or moving 100,000 m³ of cut-and-fill for a highway project, you will know precisely how many trucks you need, what you will pay, and how to avoid the bottlenecks that destroy earthworks productivity.
| Specification | 18-Ton Tata LPK 2518 | 25–30-Ton Howo / Fuso | 35-Ton+ Heavy Hauler |
|---|---|---|---|
| Gross Vehicle Weight | 18,000 kg | 25,000 – 31,000 kg | 35,000 – 45,000 kg |
| Payload Capacity | 10 – 12 m³ (loose soil) | 16 – 20 m³ (loose soil) | 22 – 28 m³ (loose soil) |
| Engine Power | 180 – 220 HP | 280 – 380 HP | 400 – 500 HP |
| Fuel Consumption | 25 – 35 L/100km | 35 – 45 L/100km | 45 – 60 L/100km |
| Daily Hire Rate (2026) | KES 14,000 – 16,000 | KES 18,000 – 22,000 | KES 28,000 – 35,000 |
| Monthly Hire Rate | KES 350,000 – 400,000 | KES 450,000 – 550,000 | KES 700,000 – 850,000 |
| Best For | Small sites, county roads, urban access | General construction, bulk earthworks | Mega projects, long haul, quarries |
The number of dump trucks required for your earthworks project is determined by one simple equation: the excavator's production rate must be matched by the trucks' combined haul capacity. If the trucks cannot keep up, the excavator waits. If the trucks outnumber the excavator's loading speed, they queue. Both scenarios cost money.
Here is the step-by-step calculation using real Kenyan field data:
How many cubic meters per hour does your excavator load? This depends on machine size, material type, and operator skill.
| Excavator Size | Loose Soil (m³/hr) | Hard Rock / Clay (m³/hr) |
|---|---|---|
| 20-Ton (Hitachi ZX 220) | 80 – 120 | 40 – 60 |
| 30-Ton (Doosan DX 300) | 180 – 250 | 100 – 150 |
| 35-Ton (Hyundai HX 330) | 220 – 300 | 120 – 180 |
The round-trip cycle includes loading, hauling, dumping, and returning. In Kenyan conditions, typical cycle times are:
| Haul Distance (One Way) | Tata 18-Ton (mins) | Howo 25-Ton (mins) | Heavy 35-Ton (mins) |
|---|---|---|---|
| 0 – 2 km (on-site) | 8 – 12 | 10 – 14 | 12 – 16 |
| 2 – 5 km (nearby dump) | 15 – 22 | 18 – 25 | 20 – 28 |
| 5 – 10 km (off-site) | 25 – 35 | 28 – 40 | 30 – 45 |
| 10+ km (long haul) | 40 – 55 | 45 – 60 | 50 – 70 |
*Cycle times assume average road conditions (murram or graded surface), moderate traffic, and 5-minute dump time. Add 20% for rainy season or poor access.
How many excavator buckets fill one truck? This determines loading time per truck.
| Excavator / Bucket | Tata 18-Ton (Cycles) | Howo 25-Ton (Cycles) | Heavy 35-Ton (Cycles) |
|---|---|---|---|
| 20-Ton (1.0 m³ bucket) | 10 – 12 | 16 – 20 | 22 – 28 |
| 30-Ton (2.0 m³ bucket) | 5 – 6 | 8 – 10 | 11 – 14 |
| 35-Ton (2.0+ m³ bucket) | 5 – 6 | 8 – 10 | 11 – 14 |
*Loading time per cycle: 30–45 seconds for 20-ton excavator, 20–30 seconds for 30/35-ton. Total loading time per truck = cycles × cycle time.
Here is the simplified version used by earthworks professionals in Kenya:
Example: You have a 30-ton excavator (2.0 m³ bucket) loading a Howo 25-ton truck. The haul distance is 3 km (one way) on a murram road.
- ›Truck cycle time: 20 minutes (haul, dump, return)
- ›Loading cycles to fill truck: 9 buckets × 25 seconds = 3.75 minutes
- ›Number of trucks needed: 20 ÷ 3.75 = 5.3 → Round up to 6 trucks
With 6 trucks, the excavator loads continuously without waiting. With 4 trucks, the excavator sits idle 25% of the time. With 8 trucks, two trucks queue at any given moment.
Here are four common project scenarios with pre-calculated fleet sizes. Use these as benchmarks for your own project planning.
Excavator: 20-ton Hitachi ZX 220
Truck: Tata LPK 2518 (18-ton)
Haul: 1 km to stockpile (on-site)
Cycle time: 10 minutes
Loading time: 11 buckets × 40 sec = 7.3 min
Fleet Size: 2 trucks
Duration: 3–4 days | Cost: KES 84,000–128,000
Excavator: 30-ton Doosan DX 300
Truck: Howo 25-ton (6×4)
Haul: 5 km to designated dump
Cycle time: 28 minutes
Loading time: 9 buckets × 25 sec = 3.75 min
Fleet Size: 8 trucks
Duration: 8–10 days | Cost: KES 1,152,000–1,760,000
Excavator: 35-ton Hyundai HX 330
Truck: Howo 30-ton (8×4)
Haul: 8 km to fill section
Cycle time: 42 minutes
Loading time: 12 buckets × 22 sec = 4.4 min
Fleet Size: 10 trucks
Duration: 18–22 days | Cost: KES 3,240,000–4,620,000
Excavator: 35-ton Hyundai HX 330
Truck: Heavy 35-ton hauler
Haul: 3 km to overburden dump
Cycle time: 22 minutes
Loading time: 12 buckets × 22 sec = 4.4 min
Fleet Size: 5 trucks
Duration: 30–35 days | Cost: KES 4,200,000–6,125,000
The daily hire rate is only the headline. The true cost of dump truck operation in Kenya includes fuel, driver allowances, maintenance, and the hidden cost of downtime. Here is a realistic breakdown for a 30-day earthworks project using 6 Howo 25-ton trucks:
| Cost Factor | Per Truck / Day | 6 Trucks / 30 Days | Notes |
|---|---|---|---|
| Daily Hire Rate | KES 20,000 | KES 3,600,000 | Includes driver, excludes fuel |
| Fuel (200 km/day) | KES 14,400 | KES 2,592,000 | 40L/100km × KES 180/L |
| Driver Allowance | KES 500 | KES 90,000 | Meal & accommodation for remote sites |
| Tire Wear & Maintenance | KES 1,500 | KES 270,000 | Murram roads accelerate wear |
| Loading / Dumping Delays | KES 2,000 | KES 360,000 | Idle time from poor coordination |
| VAT | KES 3,800 | KES 684,000 | 16% on hire rate + fuel markup |
| Total Project Cost | KES 41,700 | KES 7,506,000 | Effective rate per truck per day |
A truck that cycles in 15 minutes on a graded surface takes 25 minutes on a rutted murram road during rains. That is a 67% productivity loss. Budget for road maintenance — grading, drainage, and culverts — before trucks arrive.
A 35-ton excavator with a 2.5 m³ bucket fills a 18-ton Tata in 4 cycles — but the truck is undersized for the machine's production rate. The excavator waits. Match truck capacity to excavator output, not just what is cheapest to hire.
When a truck breaks down on a 6-truck fleet, you lose 17% of capacity immediately. On a 3-truck fleet, you lose 33%. Always contract for one standby truck or ensure your hire company can deliver a replacement within 24 hours.
If trucks must reverse 50 meters to reach the excavator, every cycle loses 3–5 minutes. Over 200 cycles per day, that is 10–17 hours of lost production. Design loading pads for direct truck access and turnaround.
The cheapest truck is often the oldest, with the highest breakdown rate. A KES 16,000/day truck that breaks down twice in a month costs more than a KES 20,000/day truck that runs reliably. Check maintenance records and fleet age before signing.
