Dongfeng TZ4Y vs TZ5Y RHD Electric Dump Trucks

Catalogue comparison: TZ4Y RHD and TZ5Y RHD

The project catalogue contains two right-hand-drive 8x4 dump-truck variants. Both rows list a 600 kWh battery and 4AMT transmission, but they are not interchangeable specifications. TZ4Y is listed at 55 t GVW, with 350 kW rated / 520 kW peak motor output. TZ5Y is listed at 80 t GVW, with 400 kW rated / 550 kW peak output. The rows also differ in wheelbase, axle entries, tyres and charging interface. The comparison below reproduces catalogue data; it does not assert payload, range, body inclusion or local approval.

Although both entries show 600 kWh, matching battery capacity does not mean matching work capability. GVW is not payload: the 55 t and 80 t labels describe gross vehicle weight classes, not tonnes of material in the body. Completed mass, body, axle distribution, legal limits and approval determine the allowable payload. A buyer should compare the vehicles only after obtaining a body-specific mass statement and a route assessment.

Choose by the job, not by the larger number

Start by describing the material and movement. Is the work a controlled quarry circuit, construction-site delivery, aggregate transfer or another defined task? Record the load density, loading method, distance, elevation, gradients, surface, traffic, waiting and daily cycle count. Identify whether trips are repeated on a fixed route or dispatched among multiple destinations. These facts shape body selection, energy needs, access, shift timing and legal mass requirements.

TZ4Y's catalogue-listed 55 t GVW class may be the more relevant candidate where the completed-vehicle mass and legal limit align with the target task; TZ5Y's 80 t class indicates a different gross-weight category. That distinction alone cannot establish which carries more useful payload in a particular country or which is more productive. Compare actual body and chassis masses, axle limits, route approvals and loading constraints. Do not infer payload or productivity from rated/peak motor output, wheelbase or battery capacity.

Check geometry against the worksite. The listed TZ5Y wheelbase segments are longer than TZ4Y's, which makes an exact dimensional and turning review particularly important, but the catalogue entries are not a turning-circle specification. Request complete vehicle dimensions, swept-path data where available, turning requirements and body overhang drawings. Inspect ramps, narrow haul roads, loading faces, passing zones and tipping locations. Ask a qualified engineer and the site operator to assess grades, cross-slope, ground condition and safe tipping practice.

If the work involves dense material, use controlled weighing to avoid overloading and to determine realistic tonnes per trip. If material density varies, specify a loading procedure that accounts for it. The body capacity in cubic metres cannot be selected responsibly without the material, legal limits and completed mass calculation. Any comparison should include the same body scope, equipment, destination, route, shift and charging assumptions.

Resolve body integration and axle loading early

Neither catalogue row defines a complete dump body. The buyer should specify volume, material, floor and side construction, liner, tailgate, cover, tipping arrangement and hydraulic equipment with the body builder. Ask for approved chassis mounting points, frame limits, body center-of-gravity envelope, axle load distribution, electrical connections and commissioning scope. Confirm whether hydraulic power equipment, controls, safety interlocks and body-up indicators are included or supplied separately.

Obtain mass calculations for empty and loaded conditions and evaluate axle distribution through the loading process. Include cab/chassis, body, pump, guards, spare wheel, fluids, occupants and options. A body raised during tipping changes stability; the site, ground bearing condition and operating instructions must be assessed for the actual completed vehicle. Do not use a catalogue GVW as a payload figure or assume the 80 t entry means the truck can legally carry that amount of material in a destination market.

The tyre and axle entries differ: TZ4Y lists DF601S / DF300H with 315/80R22.5, while TZ5Y lists DF901S / HDZ300 with 12.00R24. Verify approved axle ratings, wheel and tyre fitment, load indices and local replacement availability. A tyre size in a catalogue row does not describe every service condition or prove suitability for sharp rock, mud or a specific operating speed.

Right-hand drive is only one part of export readiness

Right-hand-drive configuration can be relevant to a market or fleet requirement, but steering position by itself does not establish that a vehicle may be registered or operated there. Verify the destination's vehicle category, homologation process, lighting, visibility, braking, dimensions, axle loads, mass limits, documentation, safety equipment and any applicable environmental or import requirements through competent local authorities or advisers. Requirements vary by market and can change, so the supplier's generic model description is not a compliance determination.

The charging entries deserve special attention. TZ4Y's row says “EU interface” and TZ5Y's says “GB”; buyers should treat these as catalogue labels to be clarified, not proof of interoperability with a specific charger or proof of market certification. Obtain the exact inlet and connector specification, protocol, voltage/current envelope, communications and accepted charger list for the ordered configuration. Have a qualified charging provider assess the destination site and confirm compatibility in a written acceptance plan.

Request the vehicle's final configuration code, right-hand-drive cab details, drawings and complete technical schedule before production. Confirm language and format of manuals, parts catalogue, diagnostics, service support and training. For export, align these items with shipping documents, destination requirements and local service capability. See the broader right-hand-drive electric truck export checklist for market-readiness questions; this comparison is specifically about the two dump-truck catalogue entries.

Build separate duty-cycle and charging cases

The same 600 kWh catalogue capacity does not promise identical energy use or range across TZ4Y and TZ5Y. The trucks have different listed weight classes, motor outputs, wheelbases, axles and tyres; the completed body and payload further affect energy. Route grade, surface, speed, weather, stops, waiting and auxiliary equipment matter as well. Request supplier guidance and use representative operational data or a monitored pilot before committing to shift performance.

Record energy by loaded and empty route segment, cycle count, starting and ending state of charge, charging energy, waiting time and ambient conditions. Define a practical reserve for delays, detours, charging interruption and route changes. Ask the supplier for the approved SOC guidance and usable-energy assumptions for each exact build. Do not estimate charge duration from capacity alone; charging power, curve, temperatures, connector compatibility and site supply all need confirmation.

Plan charger access for the actual shift: bay count, arrival overlap, load management, maintenance windows, cable reach and contingency when a charger is unavailable. If site charging is proposed, assess dust, water, traffic, impact protection and emergency access with qualified professionals. Keep the charging installation and the heavy-vehicle movement plan coordinated so that charging does not obstruct loading, tipping or recovery.

Facts still requiring supplier confirmation

The project catalogue does not specify payload, dump-body volume, range, charge duration, price, warranty, certification, production availability or test performance for either model. It does not establish destination-market approval or charging compatibility with a named charger. The photograph is a general catalogue asset and should not be interpreted as a specific TZ4Y or TZ5Y image. Obtain current written information for the exact order and destination before making commercial or operational commitments.

For a meaningful procurement comparison, request identical quote scopes, completed-vehicle mass and axle loads, body details, battery and charging specifications, destination compliance documentation, service coverage, parts support and warranty terms. Compare total operating assumptions transparently rather than extrapolating from the higher GVW, battery size or peak power.
