JBM Motors forms a joint venture with Bredamenarinibus to produce low-floor city buses called CITYLIFE in India. The buses come in 230HP CNG, 280HP CNG, and 280HP diesel variants. They are designed for Indian traffic and weather conditions, with features like a monocoque structure for strength and low weight. The production process involves trim, mechanical, electrical, and shower testing lines before final pre-dispatch inspection.

4.  JBM Motors ltd. makes a Joint Venture with European Bus maker
Bredamenarinibus (BMB) to make a true low floor City Buses
named CITYLIFE in three Variants namely 230HP CNG, 280HP
CNG, and 280HP Diesel buses.
 Our detailed market research indicated there was need for a safe,
reliable and durable intra-city mode of transport.
 The bus has been designed keeping in mind Indian traffic and
weather conditions. Some unique features include a monocoque
structure to ensure maximum strength and minimum weight.
 The bus has been developed on the monocoque body concept
which means the chassis is an integral part of the body.

5. USEFULLNESS
 It is a true low floor city city bus without having steps as like in
other buses.
 Both the Doors are Pneumatically Operated.
 Manual Ramp is their for Handicap Passenger to travel safely.
 Full Air Conditioned Sealant Proof Bus, the bus is having 39
sitting and 59 standing passenger capacity.
 The Bus is Equipped with Disc Brake at all Four wheels, full air
system (Pneumatic) with EBS and ABS with EBD.
 High Pressure Laminated sheets (HPL) are used to prevent
heating inside the bus.
 FRP & ABS are the Main internal trimming parts along with
Latest Electrical Technology.

6. PRODUCTION ENGINEERING
Production Engineering is a combination of Manufacturing
technology with management science.
Design and application of manufacturing techniques to produce a
specific product. It includes activities such as:
1) Planning Specification, and coordination of the use of resources.
2) Analysis of producibility, production processes, and Systems.
3) Application of methods, equipment and tooling.
4) Controlled instruction of Engineering changes.
5) Application of cost control Techniques.

7.  In JBM BUS Plant, PRODUCTION has Sub-Department as
follows:
1) Trim Line
2) Mechanical Line
3) Electrical
4) Showering
5) Pre Dispatch Inspection (PDI)

8. TRIM LINE
Trim line is the Body line where BUS Body is made with the help of
different components and parts as follows:
1) FRP (Fibre reinforcement Plastic)
2) ABS
3) Glass Fitment
4) Sika Flex Sealant
5) Handrails
6) High Pressure Laminating Sheets (HPL)
7) GFRP
8) Vinyl Flooring
9) Stair Noising
10) Seats Fitment
11) Exterior Aluminium Panels
12) Front Facia

9. FRP : Fiber reinforced plastic also known as fibre reinforced
polymer. It is a composite material made of polymer matrix
reinforced with fibres. The fibres are usually glass, carbon, aramid
or Basalt.
Characterstics of FRP :
 High Strength to weight ratio.
 Anisotropic in nature.
 High tensile strength with low modulus of elasticity.
 Ability to form complex shape.

10. ABS : Acrylonitrile Butadiene Styrene
 Three components from which ABS forms are Polybutadiene,
Styrene, Acrylonitrile.
 ABS can be easily machined using Turning, Sawing, Die Cutting.
 It is tough, hard and rigid and has good chemical resistance and
dimensional stability.
 They also have good electrical properties that are fairly constant
over a wide range of frequencies.
 ABS properties are little affected by temperature and atmospheric
humidity in the acceptable operating range of temperatures.

11. HPL : High Pressure laminating sheets is used in interior of a
Bus in both left and right lower side.
 HPL is the direct descendent of the original plastic laminate.
 It is considered to be one of the most durable decorative surface
materials and having properties including chemical, fire and wear
resistance.
 Common thickness range is 2 mm through 4 mm.

12. VINYL FLOORING:
 Vinyl is the covering over wooden floor inside the bus.
 Vinyl sheet is pasted over complete interior wooden plywood
with the help of adhesive.
 Two vinyl is pasted with the help of sealant joint.
 Then upto 75°C we heat the vinyl sheet from above, so that it
pasted completely.

13. MECHANICAL LINE : Initially when Bus Structure entered in line
one then following assembling process occurs as denoted:
1) Fitment of Engine Mounting
2) Base plate mounting
3) Engine mounting with transmission
4) Alternator with starter motor
5) Radiator and its mounting
6) Steering gearbox with Universal joint
7) Two way Axle with propellar shaft
8) Pneumatic fitment
9) Coolant pipes
10) Mounting of Belts
11) Demester Fitment
12) Air tanks & air bellows
13) Phasor rod, Jumping rod with relay lever

14. ELECTRICAL
 JBM CITYLIFE is Full Electronic Bus operated by Engine ECU &
TCM.
 JBM BUS is Manufactured as a Multiplex Electronic System, where
On-Board Diagnostic (OBD) is a major Benefit, which shows a
trouble code whenever their is an error in a Wiring harness or if
any Connection is missed.
 The major Electrical Component used is Battery of 200 Ampere,
Starter motor which is mounted on Flywheel housing, and
Alternator which charge the battery.

15.  Total 6 sensors are used which is used to display on dashboard
when Bus is in running condition & also in Idle condition.
1) Driver door Sensor or Driver door limit switch
2) Rear door limit switch
3) Receptical box limit switch
4) Cam sensor
5) Rear start stop box sensor
6) Fuel detect sensor
7) Crank Sensor
What is Sensor ?
A device which detects or measures a physical property and records,
indicates, or otherwise responds to it.
What is limit Switch ?
A switch that automatically cuts off current to an electric motor
when an object moved by it.

16. WIRING HARNESS
 A cable harness, also known as a wiring harness, is an assembly of
cables or wires which transmit signals or electrical power.
 System of insulated conducting wires bound together with
insulating materials, used in the electrical system .
 The thing which makes wiring harness function different is
Coupler.
 Each wire is color coded to represent a specific electronic feature.
It provides one connection point for multiple wiring
configurations.

17. POWER CABLES
 A power cable is an assembly of one or more electrical conductors
usually held together with an overall sheath.
 The assembly is used for transmission of electrical power.
 Different types of power cables are used in a Bus to connect
mechanical as well as electrical parts.
 Power cables use stranded copper or aluminum conductors.

18. SHOWER TEST
 This is the Second last stage of production process in which
we start the high pressure shower test is done.
 By this we come to know, is their any leakage in bus from
outside.
 Defect will be check and monitored by the PDI team.
 All Internal, External & Upper side of a bus is checked so
that any leakage will be not be their.

19. PRE DISPATCH INSPECTION
 Pre dispatch inspection is the last stage of Production, in which
quality engineers check each and every part which is fitted inside
and outside of bus.
 Quality engineers make Checklist and accordingly, production
team verify that points.
 Stickers, do’s and don’t’s tags and slips are pasted by PDI Team.
 In this stage BUS is completed for dispatch to the customer.
