The TZ8J electric truck is a transit mixer built for Lagos's construction boom, where ready-mix plants on the mainland and the Lekki corridor run fixed-radius delivery loops that are ideal for electrification. A mixer shuttles between the batching plant and sites a few dozen kilometers away, returning to charge at the depot every shift, so there is no range risk and no charging anxiety. This review covers the TZ8J's drum capacity, electric PTO, charging plan, and delivered cost per cubic meter for Nigerian operators.
Ready-mix delivery is a closed loop: plant to site and back, all day, every day. The truck never strays beyond the plant's charging radius, and the drum load is known. Lagos's punishing traffic also favors electric drive, because a diesel mixer idling in a go-slow burns fuel for nothing while the TZ8J draws almost nothing at a standstill. For full specs, see the TZ8J electric mixer truck page.
Nigeria's diesel price and forex exposure make energy cost the decisive line item for ready-mix operators. Our Nigeria electric truck market guide covers import duties, SON certification, and the financing structures Lagos contractors are using for first EV fleets.
The table lists production data for the standard 8 cubic meter variant from Shaanxi Fenghan Trading Co., Ltd.
| Parameter | TZ8J Value | Note |
|---|---|---|
| Drum capacity | 8 cubic meters | about 19,200 kg wet |
| Battery capacity | 420 kWh | CATL LFP |
| Motor power | 510 kW | LvKong drive |
| Drum drive | electric PTO | no separate engine |
| Range per charge | 180 to 220 km | loaded urban loop |
| DC fast charge | 240 kW | 20 to 80 percent in 75 min |
| Warranty | 8 years / 4,500 cycles | battery pack |
| FOB price | $110,000 to $150,000 | depending on drum |
The TZ8J carries an 8 cubic meter drum rated for about 19,200 kilograms of wet concrete, driven by an electric power take-off fed from the same 420 kWh pack that drives the truck. Removing the separate diesel drum engine is a double win: no second fuel bill, no second exhaust on site, and drum speed held constant regardless of road speed, which protects mix quality on Lagos's stop-start roads.
In practice the drum load is modest next to traction. A 30 kilometer round trip with discharge uses roughly 18 to 22 percent of the pack, leaving comfortable margin for 8 to 12 deliveries per shift before a depot recharge.
The TZ8J returns to the plant every shift, so a 240 kW DC charger at the depot restores 20 to 80 percent in about 75 minutes during loading windows and overnight. Plants running two shifts can add a second charger to keep four or five mixers rotating. Because the truck never leaves the plant's radius, battery swap is unnecessary.
A diesel mixer on a 30 kilometer Lagos round trip burns roughly 14 liters per load including idle time in traffic, about $11 at Nigerian diesel prices, plus a drum-engine fuel and service bill. The TZ8J uses about $2.50 of electricity per load at industrial tariffs, and removes the drum engine entirely. Across 10 loads a day that is roughly $90 saved per truck per day, or about $25,000 a year, before maintenance savings.
The FOB price of $110,000 to $150,000 is recovered within three to four years of continuous looping, and the 8-year or 4,500-cycle battery warranty covers the full typical asset life, so there is no mid-life battery replacement in the five-year budget model.
Shaanxi Fenghan Trading Co., Ltd. supplies the TZ8J with plant-compatible chute fittings, SON documentation support, and a West Africa parts buffer. Start with the Nigeria market guide for import detail, then confirm drum options on the TZ8J electric mixer truck page. For Lagos ready-mix operators, the TZ8J electric truck converts a fixed delivery loop into a durable cost advantage per cubic meter.
The TZ8J electric truck is delivered with a high-voltage isolation monitor, automatic battery pack disconnect on collision, and the multi-layer thermal barrier built into every CATL LFP pack, a chemistry chosen for its stability in hot, dusty, high-utilization duty. Shaanxi Fenghan Trading Co., Ltd. includes a structured operator course with every fleet order, covering regenerative braking technique, state-of-charge planning, charging procedure, and high-voltage shutdown. Fleets that complete the training typically improve real-world range by 6 to 10 percent within the first month, because smooth throttle application and anticipatory regen recover energy that untrained drivers waste as heat. The course also covers daily inspection of tires, coolant, and charging connectors, which catches small faults before they become downtime.
Compliance documentation travels with the truck. Conformity certificates, battery warranty terms of 8 years or 4,500 cycles, and the telematics export of energy and emissions data give fleet managers the evidence base that tenders, insurers, and sustainability auditors increasingly require. For export buyers, that documentation package is as much a part of the product as the steel and the cells.
The battery warranty is the foundation of the ownership case: 8 years or 4,500 cycles on the CATL LFP pack, transferable to a second owner, which means the truck can be sold or refinanced mid-life with a factory guarantee still running. No diesel powertrain offers anything comparable, and that difference shows up in residual value, where documented, warranted electric trucks are clearing stronger percentages of original price than worn diesel equivalents. Fleets that keep disciplined charging habits, staying between 20 and 90 percent state of charge in daily operation, routinely show 85 to 90 percent pack capacity after five years, and the telematics health report converts that directly into resale price.
Maintenance economics reinforce the point. The sealed LvKong motor has roughly one-third the moving parts of a diesel powertrain, with no oil, injectors, turbocharger, clutch, or exhaust aftertreatment to service, and regenerative braking cuts friction brake wear by an estimated 40 percent. The parts that remain are conventional wear items, tires, suspension bushings, filters, and body-specific consumables, all pre-stocked in the Fenghan regional parts buffer for the first year of operation.
From order confirmation to delivery, most export market buyers take delivery in 45 to 60 days, with Shaanxi Fenghan Trading Co., Ltd. preparing the certification file, the drive configuration, and a first-year spare parts kit in parallel so the truck arrives work-ready. The recommended first step is a route and duty-cycle review: share your daily kilometers, payloads, shift pattern, and depot power capacity, and the team will model range, charging windows, and total cost against your actual operation rather than brochure numbers. That model becomes the backbone of the financing conversation, because banks and lessors lend against documented operating savings far more readily than against projections.
Fleets new to electric trucks should start with two to five units on the most predictable route, instrument everything, and scale after the first quarter of data. Every fleet that has followed that path has expanded its electric share in the second order, because the operating numbers made the argument internally without any further persuasion. Contact the Fenghan export team to begin the route review for your operation.
