Dump Trucks

China 50 Ton Underground Mining Dump Truck

A 6x4 CMT4525E2 underground mining dump truck built around the WD12G375E211 turbocharged inline-six diesel engine, rated 375HP and paired with the 7DS200 manual gearbox. It uses 14.00-25 tyres and has a heaped dump body volume of 25m3. Designed for confined underground tunnels, it operates at a maximum speed of 41km/h and is built to Euro 2 emission standards. This configuration is used in deep-level hard rock mines where high payload and low emissions are required without AdBlue infrastructure.

Condition New
Horsepower 251-350hp

Key Benefits

What This Unit Does Well

WD12G375E211 engine is the most common 375HP powerplant in Sinotruk's mining range, so filters, injectors and oil are widely available in export markets
7DS200 manual gearbox provides reliable gear engagement in low-speed, high-torque mining conditions
18T front axle and 25T rear axles distribute weight evenly across narrow underground tunnels
14.00-25 tyres are standard in underground mining fleets and can be replaced locally in most African and Central Asian markets
25m3 heaped dump body volume matches the capacity of most 45-ton underground haul trucks in use
Max speed of 41km/h is sufficient for underground haulage and avoids excessive wear on brakes and tyres

Application Scenarios

Where It Is Used

Underground haulage of ore from a deep-level hard rock mine to a central loading point
Transport of crushed rock in confined tunnel sections with limited clearance and tight turning radii
Long shifts in continuous mining operations where engine reliability and part availability are critical
Operations in mines without access to AdBlue or urea supply, where Euro 2 compliance avoids sensor faults

Fit

Who It Is For

Mining contractors operating in Africa, Central Asia and South America with underground tunnels
Fleet managers replacing older dump trucks and needing a model with consistent spare parts availability
Engineering procurement teams sourcing equipment for long-term mine contracts with limited maintenance support
Contractors who need a 50-ton capacity truck that can operate in low-clearance, high-dust environments

Buyer Pain

Problems It Solves

Downtime caused by parts that take weeks to arrive from Europe or North America
Trucks that exceed tunnel clearance due to oversized cab or body dimensions
Inconsistent payload capacity due to mismatched axle ratings and chassis design
Lack of local availability for filters, injectors and clutch components in remote mining sites

We match the chassis code and axle load to what is available in stock or from the plant
You confirm the final specification sheet including cab colour, tyre brand and tailgate type before deposit
Unit is prepared, photographed and video recorded before loading
We book RoRo or container shipment and issue the export documents your customs needs

Quality Control

Checks Before Loading

Chassis, engine and gearbox numbers are photographed and matched to the specification sheet you approved
Engine start, gear engagement and hydraulic tailgate operation are recorded on video before loading
Paint, glass and cab trim are checked for transport damage at the loading port
Loading and lashing photos are sent before the vessel departs

Customisation

What Can Be Changed

Cab colour other than the default white
Tyre brand and spare wheel count
Additional tool box or onboard air compressor
Tailgate type change to mechanical lift if required
Fifth wheel height adjustment for trailer coupling

Honest Comparison

How It Compares With the Alternatives

4x2 underground dump truck	The 6x4 provides better traction and axle load distribution in soft or uneven tunnel floors, but has higher fuel consumption on empty runs

Use Guide

Using It Well

Replace fuel and oil filters on the interval set for WD12G375 engines, not on a generic schedule
Keep the hydraulic tailgate system checked weekly for leaks in high-dust environments
Order the clutch plate and injector set with the truck so the first service does not wait on shipping
