1 Inspection & Maintenance Station (IMS) Under National Institute for automotive Inspection, Maintenance and Training (NIAIMT) Implemented under NATRiP, Under Ministry of Heavy Industry, Govt. of India

2 Inspection & Maintenance Station (IMS) Under National Institute for automotive Inspection, Maintenance and Training (NIAIMT) Implemented under NATRiP, Under Ministry of Heavy Industry, Govt. of India NIAIMT has two facilities under IMS:- (1) Fixed Inspection Lanes, installed at NIAIMT s Silchar Jaffirbond campus. (2) Mobile Inspection Lanes, which can move to any place and can do vehicle fitness test at the spot. Fixed Inspection Lanes There are two lanes installed and commissioned at IMS lab. One lane is for Light Moving Vehicle (LMV) and the other one is for Heavy Commercial Vehicle (HCV). Both lanes are fully automated and computerized. The machines and equipments are installed and commissioned by M/s Mustang Advanced Engineering (MAE), Ohio, USA which is one of the world leaders in this sector. Mobile Inspection Lanes There are two Mobile Inspection Lanes which can move to any place and can do Vehicle Fitness test at the spot. Bothe the lanes are capable of testing LMV and HCV. Both lanes are fully automated and computerized. The machines and equipments are installed and commissioned by M/s Mustang Advanced Engineering (MAE), Ohio, USA which is one of the world leaders in this sector. Tests:- The below tests can be done for a particular vehicle at Fixed Inspection Lanes or Mobile Inspection Lanes:- 1. Pollution Test (Opacity test for Diesel version and Gas analyzing for petrol version) 2. Alignment Test (Side slip plates) 3. Headlight Test Page 1

3 4. Sound Test / Noise Test 5. Speedometer test 6. Brake test for multiple axles 7. Suspension Test (for LMV) 8. Joint Play test 9. Visual Check # Decelerometer (optional) Report and Certificate:- After every test the data is automatically saved into the computers integrated and on completion of all tests a computerized report is generated showing all test results individually. The report cum certificate is Authorized and recognized by all. Business Viability:- In India there is law to test all the commercial vehicles after particular intervals (1 year or two year) and to get Vehicle Fitness Certificate. The fitness certificate is also important for claiming Insurance. Here comes the demand for fitness testing. Only authorized centres can issue fitness certificate to a vehicle. Generally one fitness testing centre covers a zone. NIAIMT s IMS is a state-of-the-art Authorized fitness testing centre. Equipment s Brief and Specifications:- 1. Pollution / Emission test (Opacity/gas analysing): Equipment: Capelec 4 Gas analyzer/opacimeter with RPM sensor. Parameter for Petrol version: CO (% vol.), CO2 (% vol.), HC (ppm vol), O2 (% vol.) and Lambda. Parameter for Diesel version: Opacity ( /m), takes 10 accelerations. Test time: 8-10 mins CAPELEC: CAP Alignment Tester (Side slip plates): Description: Alignment testers are also called side-slip plates because they measures sideways movement of vehicle s wheels when the vehicle is moving forward. The side-slip plates are fitted with a sensor that measures the sideways drift of the vehicle in fit/mile or meter/km. Plate Dimension (with mat): 740X860X44.5 mm Page 2

Speedometer test: Type: Roller speedometer with motor drive and without motor drive. Make: Mustang Advanced Engineering (MAE), Ohio, USA. Light Duty Speedometer Tester 6. Roller Brake Tester: Type: Four-roll configuration, dynamically balanced; Rear roll set grooved; Offset rear rolls from front rolls (57.15 mm / 2.25 in) Make: Mustang Advanced Engineering (MAE), Ohio, USA. Maximum Load per Axle: 13,000 kg / 28,660 lbs for Heavy Duty; 3,000 kg / 6,614 lbs for Light Duty. Page 4

6 Rolls (For Low duty vehicles): Number of Rolls: 4 Minimum Track Width: 762 mm / 30 in Maximum Track Width: 2591 mm / 102 in Diameter: 202 mm / 7.95 in Length: 914 mm / 36 in Roll Spacing: 400 mm / in Brake Testing (For Low duty vehicles): Max. Brake Force / Wheel: kg / 0-1, 124 lbs / 0-5 kn Speed of Test: 5 kph / 3 mph Motor x 2: 3.7 kw / 5 hp Sensor Type: Load Cell Coefficient of Friction: μ Rolls (For Heavy Duty Vehicles):- Number of Rolls: 4 Minimum Track Width: 914 mm / 36 in Maximum Track Width: 2743 mm / 108 in Diameter: mm / in Length: 914 mm / 36 in Roll Spacing: 470 mm / 18.5 in Brake Testing (For Heavy Duty Vehicles):- Max. Brake Force/Wheel: 0-3,060 kg / 0-6, 744 lbs / 0-30 kn Speed of Test: 3 kph / 2 mph Motor x 2: 7.5 kw / 10 hp Sensor Type: Load Cell Coefficient of Friction: μ Page 5

7 Heavy Duty Roller Brake tester 7. Suspension Tester: Type: The BM40000 suspension tester is designed for axle load of up to 2000 kg. The suspension tester is using the EUSAMA measuring principle for testing the suspension system of the wheels. The unit consist of a one bed system with a vibration plate for left and right wheel, which controlled by an electrical gear motor. Results: The test results are as standard shown on an aluminium display with large point meters for left and right wheel values and large 50 mm digital readout of imbalance between left and right wheel. Test Procedure: The test is performed by vibrating a plate vertical from app 25 down to 3 Hz simulating all road conditions. During the test sequence the wheel weight is continuously measured and the lowest saved for comparison with the static wheel weight. The ratio between the lowest weight measured and the static weight is determined as the EUSAMA value, which is also known as the Road Adhesion value. The value is presented in percentage on the display and printout. Suspension tester Page 6

The stub axles, steering pivot points, suspension, hinge points and bearings all can be inspected while 4 hydraulic rams induce 45 movements. Features: Hand held pendant with flashlight and built in controls High friction wheel surface 4 hydraulic rams induce transverse and longitudinal movements Maximum Axle Load: 15,000 kg / 33,075 lbs for Heavy duty Specifications: Thrust Force: 3,000 dan Power of Motor: 2.5 Kw / 3.5 hp Operating Pressure: 120 bars / 1,740 psi Longitudinal Travel: 80 mm / 3.15 in Transversal Travel: 80 mm / 3.15 in Joint Play Tester 9. Visual Checks: To reduce human intervenes in the overall report we do only few minor visual checks. Mobile Inspection Lane Page 7
