Construction challenges

Why UD Trucks for construction

The tough two.

Solid, smart and future-designed. Meet UD Trucks’ dependable duo for construction.


The Quester is UD Trucks main vehicle for construction assignments because of its endurance. A reliable, cost-efficient and versatile workhorse that provides the manoeuvrability and ground clearance to handle the roughest terrain.


The Croner is a flexible, efficient compliment to the Quester. Suited to more specific construction tasks, it is available in three GVW ranges and saves both time and fuel.


The Quester is designed to make superstructure installation easy. Comprehensive bodybuilder instructions and power take offs for specific applications make it ideal
to be adapted for all assignments and road conditions.

Break new ground.

Power. Durability. Operational efficiency. Make the most of the 40 tonne Quester, with 24 inch tyres and extra wide, super-strong chassis. In heavy construction, 6×4 and 8×4 rigid configurations provide flexibility to match the truck to the job.

Higher average speed

A wide choice of flexible, powerful driveline combinations ensure high average speed and excellent performance in all applications. A higher average speed means your trucks can make more journeys.

The perfect off road partner

The Quester is specially adapted for construction. A wide, stable chassis is built for rough, hilly terrain. High torque means good engine response, while crawler gears and wide ratio options guarantee easy starting and controlled driving at any speed and in all conditions.

Higher payload capacity

A variety of specifications on wheelbase and axles can maximise payload capacity. The Quester in particular is designed for handling heavier loads in tough conditions.
Well-dimensioned components deliver extra load capacity, improving productivity.

More profitable driving

UD Trucks driver training is structured to further improve driver performance, while an on-board fuel coaching system helps maximise profitability on every assignment.

Agile on any terrain

The construction cab on the Quester is designed for agility in tough conditions. A purposely designed front steel bumper position ensures maximum ground clearance
and approach angle.

High component durability

All UD construction models are tested to their limits in order to provide greater durability than our competitors. Strong and reliable Japanese quality components guarantee a long life of productive uptime, whatever conditions you plan to put the trucks through.

Longer service life

Optional hub reduction rear axles increase service life in tough conditions. Effective suspension reduces stress on the chassis and superstructure, which can mean longer intervals between servicing.

High torque: Low revs

Fuel consumption is minimised by the high torque delivered at low revs. A wide maximum torque range results in a greater fuel economy and improved profitability on every assignment.


Powertrain optimization

The Quester has a wide choice of rear axle ratios for different applications. This means the vehicle can provide excellent fuel economy at cruising speed in top gear, with no compromise on performance.


Taking the strain

Designed for long days onsite, the Quester has the option of an air suspended driver’s seat. This helps increase comfort when manoeuvres are tight and the workload is heavy.

Effective air conditioning system

Because hot days behind the wheel demand good quality air-con.

Easier assignments

Our construction cabs are designed to minimise fatigue via well-planned ergonomics. A smart instrument cluster and information display provide exactly what’s needed to
focus on the job in hand. Such innovations lead to happier drivers and lower driver turnover.

Increased visibility

All construction cabs provide excellent all-round visibility with large glass areas and strategically placed mirrors. Effective and protected headlights are positioned on the cab side panel of the Croner.

Stress-free braking and handling

Both trucks offer excellent handling and stability. A front stabiliser increases safety if forced to corner at high speed. The Quester has full S-cam air brakes with automatic slack adjuster.

Quester specifications can operate in these various conditions. The truck has been tested in various markets for long distances, so that we make sure customers will be satisfied with the toughness and robustness.
