A reliable auxiliary braking system on Quester helps to maintain safe speeds and delivers powerful braking without fade.
The UD Extra Engine Brake (UD EEB) is a powerful engine brake that is optional with the 11-liter engine.
It back pressures the cylinders within the engine, using exhaust pressure and a patented ingenious valve system. There is no generation of heat or extra wear and tear on equipment.
The presence of the hydraulic retarder makes downhill driving easier. In loaded vehicles in particular, the vehicle speed can be controlled without applying the service brake. This reduces brake wear and prevents accidents due to brake fade.
When not coupled with a hydraulic retarder, ESCOT features a Brake Max Mode which allows the transmission to continuously downshift for a more effective use of the EEB.
Cutting out the need for manual gear-changing means drivers can keep their attention on the road. Therefore the addition of ESCOT and option of Automatic (Allison) in Quester are both good news for operational safety.
Other Quester braking functions include:
• Exhaust brake on GH8E and GH11E enables fast, reliable engine braking
• ABS (Anti-lock Braking System) improves braking on all surfaces
• Full S-cam air brakes are super-durable for constant use
Quester cab provides first-class all-round visibility and depending on customer preference or regulations there are two types of rear view mirrors, namely Japanese type and ECE certified.
Front Underrun Protection system
The Quester’s cab exterior has been designed and developed with the focus on safety. The Front Underrun Protection System (FUPS) is equipped to prevent smaller vehicles from being wedged under the front in the event of a collision.
With extended ADR, Quester's electrical system is encapsulated and protects your cargo from external thermal anomalies. ADR-adaption also means that the Quester is regulated for safe transportation of hazardous substances.
Quester is fully ECE (Economic Commission for Europe) compliant, meaning that cab safety, braking, ADR, lighting and noise requirements are all certified and approved to European standards. ECE R29 for cab strength is part of this certification.
UD Trucks currently offers several useful courses for drivers. This training helps even experienced drivers improve their efficiency behind the wheel for more cost-effective and safe driving.
