countrywide coverage and trust on following product

Company Profile

• SSWIM Scales

• Applications: Dynamic and Static Weighing of Trucks,

Overload Control, Freight Terminals, Data Collection for

Pavement Design and Rehabilitation, Weight/Dimensions

Violation Enforcement

• Brief Overview: The slow speed weigh-in-motion scales

manufactured by IRD offer superior weight enforcement, greater

vehicle throughput and excellent stability of operations. The

development of iSINC™ Electronics- the heart of IRD’s core

system technologies- is a tremendous achievement towards ITS

Industry, that allows for greater flexibility, modularity, self

diagnostics and expandability in the competitive world of

weighing equipment.

Controller Rack

Company Profile

• This single controller can integrate variety of sensors in

receiving their inputs and then controlling multiple hardware

modules yet in absolute modular fashion. IRD’s SSWIM Scale

boasts a design to the true spirit of ASTM 1318 that knocks

down axial (lateral) forces with no mechanical movements, less

number of sensors and hence exhibits very low maintenance

over its life cycle.

Company Profile

• Portable/ Mobile Weighing Systems

• Applications: PAT/ IRD’s Dy-SAW and DAW300 PC equipment

has revolutionized the world of mobile weighing in Weight

Enforcement applications. These systems may be used in Dynamic

or Static Mode in completely portable or semi-permanent

installations.

Larger weighing surface and simple

design of PAT Bending Plates are the

key attributes of an intelligent built to

cover increased weighing capacity and

performance requirements. PC based

application is as simple as ready-to-go

in its easy set-up, configuration of all vehicle classes and display

of per-vehicle information like speed, wheel loads, axle weight and

GVW information as per international standards.

Company Profile

The Dy-SAW (the dynamic and static) is one of the recent

developments in IRD’s SAW Series of Wheel Load Weighers which

holds OIML certification to its credit in the respective accuracy

class desired by enforcement agencies.

Company Profile

• Full Deck Static Weighbridges (Pitless, Semi-Pit

and Pit Types)

• Application: Industrial weighing in Legal-For-Trade

applications, GVW violation and Citation

The weighing industry is very much familiar with weighing

complete vehicle/ Truck in one-go. These scales are used in

variety of applications with major use in industrial, commercial

and enforcement weighing applications.

Company Profile

• i-Toll System- Electronic Toll and Traffic

Management System (ETTM)

• IRD’s i-Toll System is an intelligent toll having reliable hardware

and operating mechanism that enjoys utmost distributed

architecture. Each sub-set of

toll system whether it is a lane

sub-system or plaza sub-system shall

work like independent soldiers to

guard against revenue pilferage

and performance hiccups.

Company Profile

The powerful Tolling Software allows integration and receiving data

from multiple plaza environments and capable to generate

configurative, statistical, financial and diagnostic reports. IRD’s

Dynax ™ Sensors technology is one of the most reliable axle

sensors technologies used for Automatic Vehicle Classification

(AVC). In addition our toll system uses, superior Access Control,

Incident Detection and Multi-Modal Payment techniques (RFID/ e-

Tags, Smart Cards) used in the i-toll system.

Traffic Counters are also supplied as portable or permanent field

applications on highways and motorways.

Company Profile

• Crack Sealing Equipment and Services

• Crack Sealing is a preventive maintenance technique to protect

damage to the pavement due to moisture, water and

incompressible solids. This is an ideal sealing solution for linear

cracks, large block cracking and pavement joints.

• Pavement cracking can cause pre-mature failures and

devastate the service life of our roadways. A timely chosen

treatment method can save millions with our crack sealing

equipment and professional services. Our crack sealing solution

may be applied to both flexible (Asphalt) and rigid (Concrete)

pavements alike.

• Collaboration with Marathon Equipment Inc, has led us a way

forward in just one gallop to provide superior crack sealing

equipment with correctly engineered hot-applied sealant

material and requisite services

Company Profile

• Pavement Testing

• National Engineers offers Dynatest‘s superior pavement

engineering products for the long term performance and testing

of highways and air fields. Falling Weight Deflectometers (FWD)

are one of the most important pavement testing techniques to

ascertain pavement stability over its designed life besides

planning and implementing the correct pavement maintenance

technique. Road Profilometer can collect variety of data at traffic

speed to get complete picture and pavement characteristics.

• A recent HWD Equipment/ Unit purchased by National

Highway Authority (NHA) has had completed its one year of

valuable data collection operations on major highway (N-5) and

Motorways of Pakistan. The Unit has also been put to service

for pavement testing on newly built Islamabad Airport.
