PROJECTS
Over 1000 forklifts flameproofed
What began as a minor sideline for Chess Engineering in
1970 has grown into a major activity with its own autonomous
division within the company. With some 1000 forklifts modified
to date – most of them in recent years – Chess
Flameproof has become a market leader in this highly specialised
area. Some of our recent projects are listed below.
JLG
1930S
- Zone - Zone 22
- Motors – DC technology
- Application – grain handling
- Technique used – Ex td, Ex md, Ex id,
Ex n
Following an exhaustive risk assessment, the design
involved enclosing all electrical components to exclude
the ingress of dust particles and to limit surface
temperatures. The design stage was extremely challenging
due to the limited space available for modifications,
a common problem with most mobile
equipment. Manufacturing of all designed components took place in our workshop
with the equipment being installed in less than six
weeks

JLG
DVL
- Zone - Zone 22
- Motors – DC technology
- Application – grain handling
- Technique used – Ex td, Ex md, Ex id,
Ex n
As with its big brother above, usable space was a
major issue. This project was completed alongside
the JLG 1930s which allowed our design team to apply the
same theories, standards and logic.

NICHIYU
FBR
- Zone - Zone 1
- Motors – DC technology
- Application – various
- Technique used – Ex d, Ex e, Ex i, static
dissipation
Designed and successfully tested to certification
level in accordance with the relevant Australian
standards for electrical equipment in hazardous areas,
this conversion utilised components designed and
manufactured in kit form allowing for reduced costs
and faster turnaround. All Ex d and Ex e enclosures
as well as all mechanical components required for
the conversion were designed and manufactured in-house. |

KOMATSU
FD - 16
- Zone - Zone 1 and 2
- Application – various
- Technique used – water cooling, water-based
and parallel plate flametrap exhaust conditioner
This project involved flameproofing several different
diesel Komatsu models to adapt to the requirements
of Zone 1 or 2 classifications in accordance with
various Statutory Regulations and Australian standards.
Two types of starting systems were used: on-board
air and remote electric. All mechanical and electrical
modifications were designed and manufactured in-house
to meet the customer’s specifications. A
range of options and modifications were provided
which included installing flashing beacons, work
lights, reversing alarms and windscreens. |

TOYOTA
7 SERIES
- Zone - Zone 1 or 2
- Application – various
- Technique used – water cooling, water-based
and parallel plate flametrap exhaust conditioner
This project involved flameproofing several different
diesel Toyota models in accordance with the Australian
standards to Zone 1 or 2 requirements. Both on-board
air and remote electric starting system were used.
All mechanical and electrical modifications were
once again designed and manufactured in-house to
the customer’s specifications. Apart from essential
modifications, various flameproofed optional extras
were provided and included flashing beacons, work
lights, reversing alarms, windscreen and Ex d windscreen
wipers. |

TENNANT
6400
- Zone
- Zone 2
- Application – various
This project involved the flameproofing of a diesel
powered sweeper in order to meet the Zone 2 standards.
It is equipped with an automatic shutdown system, an
onboard isolation system and custom-made brushes in
order to comply with the regulations. |

Mitsubishi
FD35ANT
- Zone
2
- Application – various
This project involved flameproofing the 3.5 tonne
diesel Mitsubishi model to adapt to the requirements
of Zone 2 classification in accordance with various
Statutory Regulations and Australian standards. On-board
air start was fitted together with a range of modifications
including flashing beacons, work lights, reversing
alarms, full custom-made, all-weather steel cabin
and a speed limiter |
