5 Sample answer:  

1

The aim of the design was to produce an articulated dump truck with greater power and the ability to carryy increased payloads. The designers considered the needs of users, for example, quarries, landfill carr sites, the forestry industry and construction sites.

 

2

The new design has a 5.9 litre engine with a top speed of 50 kph.

 

3

The truck has a maximum payload capacity of 20 tonnes, or 12 m 3. The increased dimensions allow the truck to carry carr y a payload 15% greater than before.

 

4

The powerful engine drives the truck through six forward gears and three reverse gears. One main advantage is that the driver can choose manual or automatic transmission. The design uses a twin hydraulic system, one for steering and tipping and the second for braking and suspension. In addition there is a power-assisted dual braking system.

 

5 The

 

6 The

redesigned driver’s cab features reduced noise and vibration from the engine, plus improved  visibility and stability stability.. AC is fitted fitted as a standard standard feature.
