ZT Loader 4WD: The Ultimate Mud Master
7.84 t Weight · 75 kW CUMMINS Engine · 70–75 kN Traction
What's the biggest headache on site? Mud pits and steep slopes. But the ZT loader laughs in the face of rough terrain — its smart 4WD system is the ultimate “mud master”.

20+ Years Export Experience, Engineered for Mud, Slopes, and Tight Sites
As a professional loader manufacturer with more than 20 years of export experience, Taian Zhengtai (ZT MACHINE) has delivered backhoe loaders to construction, municipal, and utility contractors in over 60 countries. The ZTW30-25 was engineered to solve one specific problem: machines that stall out in mud pits, spin out on wet slopes, and cannot navigate tight urban plots.
Buyers sourcing through Chinese construction machinery export frequently ask how a 7.84 t machine maintains 70–75 kN traction without sacrificing fuel economy. The ZTW30-25 answers with an intelligent 2WD/4WD system: 2WD for transport cutting fuel consumption by 20%, 4WD engaging all four wheels instantly when mud, sand, or steep slopes appear. The switch is one-touch — easier than changing songs on your phone.
Productivity is measurable in every mode. 30° gradeability and 500 mm ground clearance allow the ZTW30-25 to climb wet slopes and clear rocks with stability. A 4,300 mm minimum turning radius lets it maneuver in tight urban alleys. Working device action time on the loader end is under 12 seconds. Every saved minute is a saved dollar.
Every structural element is built from verified heavy equipment components. The 2,320 mm wheelbase with 1,910 mm / 1,820 mm tracks delivers perfect balance — stable under full bucket load, steady on lateral slopes, no wobble. 19.5L-24 rear + 14-17.5 front tyres grip like glue.
Our factory price direct-supply model removes intermediaries, delivering best value to contractors, rental fleets, and government infrastructure buyers. We support OEM branding, custom paint, and third-party inspection (SGS / BV) at any stage. Spare parts — wet brake components, hydraulic hoses, filters, and tyres — ship in wooden boxes within 24 hours of an urgent request.
Why do contractors choose the ZTW30-25? Because it solves four operational problems at once: getting stuck in mud, losing traction on slopes, wasting fuel on transport, and needing two machines to dig and load. The ZTW30-25 keeps you on schedule while others wait for a tow. That is true efficiency — a 24/7 “money-making machine” that pays you back.
Smart Switching = Real Skill
Driving a ZT loader, wouldn't it be great if highway cruising and off-road work were equally easy? The secret is the “Smart 2WD/4WD” switch.
On paved roads? Use 2WD (rear-wheel drive)
Drives like a car on the highway: smooth and fuel-efficient
Less wear and tear, longer component life
Hit mud, sand, or a steep slope?
Flip the switch, instantly engage 4WD
Power goes to all four wheels, traction maxed out
With 70–75 kN of raw power, getting stuck is not an option
This isn't just about getting unstuck — it's your secret to staying on schedule. While others wait for a tow, you're already half a day ahead. Now THAT's true efficiency.
Rock-Solid! The Chassis Magic of ZT Loader
Want 4WD to work its best? You need a rock-solid chassis. ZT loader nails it:
Stability Secrets
2320 mm wheelbase + 1910 mm / 1820 mm tracks: Perfect balance
7.8 t weight: Keeps it planted, no wobbling
Not an elephant on a skateboard — it's a tank on the move
Clearance Champion
500 mm ground clearance: Curbs? Rocks? Bring it on
Climbs 30° slopes: Front lifting? Never happens
High-centering: Not in this lifetime
Bottom line: this chassis turns 4WD power into pure productivity, not shaky business. While others get stuck or wobble, you stay steady and get paid.
