Project: Truck Specification for Best Operational Efficiency

Reference: TE252

Last update: 20/06/2005 11:38:46

Objectives

1. To review the variety of goods vehicle types (motor vehicles, trailers and semi-trailers) over 3.5 Tonnes GVW/GTW available to operators and to evaluate their operational suitability through the development of a draft Good Practice Guide text. This review of options should cover not only complete vehicles, but also major vehicle component and systems options. The review should focus on generic vehicle, component and systems classifications and should, as far as is practicable, avoid both criticism of specific manufacturers' models and any favourable bias towards one manufacturer.


2. To demonstrate, via case studies and examples, the different types of specifications required by assorted operators, highlighting the optimum applicability of certain vehicle, component and systems specifications to particular operations. Reference should be made, where applicable throughout, to existing relevant TransportEnergy BestPractice publications and other readily available independent industry information.


3. To provide indications of whole life costing benefits resulting from accurate initial specification. These indications should serve to highlight the importance of calculating long-term costs, such as fuel and maintenance spend, at the time of developing a vehicle specification.

4. To provide checklists and questions to help operators specify the most suitable vehicle for their operation.


5. To offer guidance to help the operator decide the level of specification actually required, i.e. helping to answer questions like "Do I need this component/optional extra and what will I get from it?"

Description

1. Review the variety of goods vehicle types (motor vehicles, trailers and semi-trailers) over 3.5 Tonnes GVW/GTW and major vehicle component and systems options available to operators, evaluate their operational suitability and determine the range of issues, relating primarily to fuel efficiency, of which operators should be aware when undertaking truck specification, including, but by no means limited to, items such as:

Vehicle classes

Vehicle weights (addressing both legal maximum weights, including significance of axle configurations, and operational weight issues such as calculation of payload and diminishing loads)

Vehicle dimensions

Evaluation of the respective advantages and disadvantages of operating rigid, articulated and drawbar vehicles

Evaluation of the operational suitability of the variety of available vehicle, trailer and semi-trailer body types

Evaluation of the operational suitability of the variety of available vehicle, trailer and semi-trailer component and systems options, including, but by no means limited to;

Aerodynamic equipment
Axles
Braking systems
Cabs
Chassis materials
Driveline specification
Engine specification (comparisons of bhp)
Fuels
Fuel tanks
Lubricants
Telematics systems
Tyres
Wheels
Ancillary equipment

Summary of results

  1. This publication provides independent and authoritative
    guidance on vehicle specification. It will show you just
    how easy it is to produce a fit-for-purpose specification
    and will take you through the key stages of vehicle
    specification. Sections 1-3 cover the basics of vehicle
    specification, while Sections 4-6 contain more detailed
    information.
