Question 3
3.1 Read the scenario and answer the following questions:
Machines that construction companies use:
The mini-loader, and builders use it to move materials around a building site. It
has a scoop in the front, which the driver pushes into a pile of sand. Then the
arms of the loader lift the load of sand into the air. It uses diesel fuel in the
engine as its source of energy. The engine turns a powerful pump that pumps
hydraulic oil through hoses and pistons.
Maria is going to need a big tip truck to deliver sand to different building sites.
The load must not fall off when the load back is horizontal. A big truck like that
can be dangerous if it crashes into cars, it can flatten them! Also, the loads of
rock, gravel or sand that tip trucks carry are usually very heavy, and when the
load bed is lifted, it can start pouring out very quickly. This load can injure a
person standing too close to it.
People should be trained to work safely around tip trucks. A tip truck needs to
have warning lights and beepers so that everyone will know when the load bed
is being lifted. Maria needs a model of a tip truck to train her staff on how to be
safe when they work around the truck.
3.1.1 How does this mini loader lift its arms?
