An EV truck is no longer an experiment in Gulf mining. Qatar's limestone and aggregate operators run short, repeatable haul loops inside fenced quarries where an electric truck can replace a 40-ton diesel dump with a measurable and durable operating-cost case. The TZ5Y is an 80-ton class electric mining truck built for exactly this duty: a 450 kWh CATL LFP pack, fast battery swap in under six minutes, and a cabin and pack cooling strategy tuned for 50°C ambient heat. For a site that moves two million tonnes of stone per year, the daily energy math is simple and the payback is short enough to win board approval in a single budget cycle.
Limestone is a low-value, high-volume bulk commodity, which means haul cost per tonne is the only number that decides margin. When diesel sits near 0.55 USD per liter and a quarry burns 30 liters per hour per truck, the fuel bill alone can exceed the depreciation of the vehicle. Electrification attacks that bill directly, and because the route never leaves the site, the operator controls the entire energy chain from swap bay to solar buffer.
The typical Qatar limestone quarry runs a 3 to 6 km loaded haul from the blast face to the primary crusher, then returns empty on the same ramped road. That cycle repeats 60 to 90 times per shift across a 20-hour operating day. With an 80-ton payload class and a 450 kWh battery, the TZ5Y completes roughly 18 to 24 full cycles per swap before it needs energy. Because the route is fixed and the load is predictable, regenerative braking on the descent recovers 12 to 18 percent of the outbound energy, which is the single biggest reason an electric truck beats diesel in quarry work.
Haul road grade decides everything. On a 6 percent average ramp, the descent regen covers most of the climb on the next empty return. Operators report that battery state of charge settles into a steady band after the first two cycles, which means the pack is never deep-cycled during a shift. That steady band protects the 8-year or 4500-cycle battery warranty that CATL offers on the LFP cells, and it keeps capacity fade inside the contract envelope for the full service life of the truck.
Gross vehicle weight lands near 130 tons with a full load, and the rigid frame uses the same welded box section proven on diesel mining dumps. The difference is that the TZ5Y carries its mass low in the chassis, which lowers the center of gravity and improves stability on the side slopes common around limestone benches.
Battery swap is the core of the TZ5Y design. A 450 kWh pack is exchanged in 5 to 6 minutes using a gantry or side-pull rig, so a truck is never parked at a charger for hours. A quarry running four trucks needs two spare packs in rotation and one swap bay. The table below shows a representative energy plan for a single 80-ton electric mining truck on a 20-hour operating day.
| Parameter | Value | Note |
|---|---|---|
| Payload class | 80 ton | Gross vehicle 130 ton |
| Battery capacity | 450 kWh CATL LFP | 262-600 kWh range across family |
| Cycles per swap | 18-24 | 3-6 km haul loop |
| Swap time | 5-6 min | Gantry exchange |
| Regen recovery | 12-18% | Descent to crusher |
| Daily energy | 7,200-9,000 kWh | 4-truck site ~36 MWh |
| Peak charger | 360 kW DC | Opportunity top-up |
The 360 kW DC fast charger is used for opportunity top-ups between shifts, not for full daily recharging. Most sites pair the swap bay with a 1 to 2 MWh buffer of stationary storage charged on the off-peak Qatar tariff, which flattens demand charges and keeps the fleet running through grid dips during peak summer load.
Qatar summer ambient regularly exceeds 50°C, and a mining truck's battery and motor both shed heat under load. The TZ5Y uses liquid thermal management on the pack with a dedicated chiller loop, plus a cabin pre-cool that runs from grid power before the shift starts. LvKong motors in the 282 to 510 kW band are de-rated above 45°C only at the very top of the torque curve, so the 80-ton class still climbs the ramp at full usable output.
Key heat-control steps for Gulf sites:
Dust is the second enemy after heat. Limestone fines coat radiator fins and cut cooling by 20 to 30 percent in a month if ignored. A weekly high-pressure wash of the motor and pack enclosures is part of the standard Qatar service plan, and it is cheap insurance against a mid-summer capacity drop.
A swap-based site still needs a charging home for the spare packs. For four trucks and two rotating packs, a 720 kW DC combi fed by a 2 MWh buffer covers the night recharge with margin. The buffer is charged from the grid at 0.08 USD per kWh off-peak, which is what makes the daily energy cost land far below diesel. Operators who add 500 kW of rooftop or carport PV shave another 8 to 12 percent off the bill and gain resilience during any grid event.
Cable management is simple because the truck never plugs in at the face. The swap bay carries the only high-power connection, and the maintenance team services it on a fixed schedule. That concentration of high voltage in one controlled location is also a safety win for the site's high-voltage isolation plan.
Diesel mining dumps in this class burn 28 to 40 liters per hour under load. At a Qatar diesel price of about 0.55 USD per liter, a 20-hour day costs 300 to 440 USD in fuel alone. The same electric truck draws about 8,000 kWh per day; at an industrial rate near 0.08 USD per kWh that is 640 USD less per truck per day. Over a 300-day year the saving reaches 190,000 USD per unit before maintenance.
| Cost line | Diesel 80t dump | TZ5Y EV truck |
|---|---|---|
| Energy per day | 330-440 USD | 640 USD gross / -190 USD net |
| Maintenance per year | 42,000 USD | 18,000 USD |
| Brake wear | High | Low (regen) |
| CO2 per year | ~1,100 t | ~0 at tailpipe |
| 5-year saving | - | ~1.0M USD per truck |
Maintenance falls because there is no engine, no exhaust aftertreatment, and far fewer rotating parts. Brake linings last two to three times longer thanks to regen, and the only major scheduled item is the chiller coolant and the pack cooling fins. For a finance manager, that predictability is as valuable as the raw fuel saving.
Mining sites already run strict permit-to-work systems, and the TZ5Y slots into that culture with a high-voltage module added. New operators complete a one-day classroom on LFP pack behavior, isolation tags, and emergency response, then a half-day on the simulator covering swap-bay etiquette and ramp recovery. The result is a crew that treats the electric truck as a normal asset rather than a mystery, which is the real key to uptime.
Because the pack is swapped, not charged, at the face, the crew never works around a live DC connector during production. The only high-voltage task happens inside the fenced swap bay under a permit, which reduces the exposed population to the maintenance team alone. That is a cleaner safety posture than a depot full of plugged-in chargers.
The TZ5Y shares its 450 kWh LFP architecture with the proven TZ5E electric dump truck, so spare packs and swap rigs are cross-compatible across a mixed fleet.

For quarry managers weighing the switch, the decisive points are simple: fixed short loops, predictable loads, and on-site energy control. Those three conditions make the EV truck the lowest-risk first step in any Qatar decarbonization plan, and the TZ5Y is built to prove it on the limestone face.
