Chapter 6. VEHICLE SELECTION. STUDY OBJECTIVES. At the end of this chapter students will be expected to: Discuss the role of vehicle selection and design in terms of fleet plans. Understand the implications of custom-built vs standard vehicles.
At the end of this chapter students will be expected to:
6.1.1 THE IMPORTANCE OF VEHICLE SELECTION AND DESIGN
(i) where the vehicle will operate - in the city or in suburban areas;
(ii) on what terrain it will travel - flat or mountainous; and
(iii) what speeds the vehicle will attain.
Once it has been decided that a custom-built vehicle is needed the following are the main points to be considered:
(b) Size of body
(c) Body design
– flatbed, box (don’t make vehicle to specialised so that it is not able to carry any other goods
(d) Choice of material
(e) Interior fitments
The interior of a vehicle can also be designed to provide equipment, such as
to prevent the loads from moving.
(b) Access to the load
(c) Moving the load inside the vehicle
(d) Moving the load onto and off the vehicle
Advantages of using a container:
Articulated vehicles are very popular:
(b) Body size and shape
(d) Gradability and traction
(e) Ancillary equipment
(a) Equipment life
Economic life - Period over which an asset (machine, property, computer system, etc) is expected to be usable.
(b) Life-cycle costing
6.4.2 VEHICLE COSTS
Basic concept of life-cycle costing
Total unit costs are affected by each of the following:
(b) Operations – rises gradually with fuel and tolls.
(d) Downtime – vehicle not available for service
(e) Obsolescence – obsolete - can’t do the job
(f) Inventory costs – supports the repair function
(g) Life costs – sum of fixed and variable costs
