Hi all, does anybody know where we could find qualified reach operators ?
We are looking for about 20 reach operators and are struggling to find one.

Have a wonderful day!

some interesting statistics:

In South Africa, deaths per 100,000 = 43 . This is shocking!
In SA - 18 000 people are killed annually and 150 000 are severely injured. (Medical Research Council statistics)
On a daily basis, 45 people die and 410 are injured, with 25 people becoming paralyzed.
Road crashes are the main cause for death in the youth, age 5 - 29. (Ref : World Health Organisation)
According to the National Injury Mortality Surveillance System (NIMSS) of 2010 SA’s annual road traffic fatality burden is estimated in the region of 18 000, with road traffic deaths of 43 per 100,000 (UK: 6 per100 000, Australia: 8 per 100 000, USA: 14 per100 000 - according to WHO.) CSIR says road crashes costs SA R309 Billion annually. DoT still loosely talk about approximately 14 000 deaths a year- but most people involved with road safety feel these are largely incorrect and the crashes/deaths and injuries are underreported.

Today has been such a busy day, exciting things to come for us!

Back to our usual topic of the week,
How can I diagnose what is wrong with the steering of my vehicle?

The best advice is to monitor how your vehicle steers on an open stretch of road. Check for the following:

If the car wanders slightly from side to side during the test it may be due to incorrect, or uneven, wheel alignment, loose steering gear, or an uneven load.

If the vehicle starts to deviate to one side the moment you let go of the wheel, it may be due to a major difference in tyre pressure between the left and right sides, improper rear wheel tracking, tyres not the same size, or a broken or sagged spring. It may also be a result of any of the faults mentioned in the previous paragraph.

If you take a sharp corner and the steering wheel is reluctant to return to the straight-ahead position, or the steering requires too much effort, this may be due to low tyre pressure, binding steering linkages, damaged suspension arms, incorrectly adjusted steering gear or sagging front springs. A power-steering system might have a low fluid level, a defective pump, a sticky valve spool, a loose belt, or a kinked or clogged hose.

If the steering wheel has excessive play, it will also have excessive kickback. This may be due to worn or loose steering linkages, a worn or badly adjusted steering box or improperly adjusted front-wheel bearings. Air in a power steering system could also result in excessive play.

Tyre squeal on corners is usually due to low tyre pressure, but can also be caused by incorrect toe or camber.

Vehicle components and factors which may affect steering include the following:

Steering gear ratio and back lash: The steering gear provides mechanical advantage for the driver to guide the vehicle by exerting only a small amount of physical effort at the steering wheel.

Steering linkage connection: They must provide free movement of the linkage to transmit driver’s effort at the steering wheel to the knuckles. If there is more play in the joints, most of the efforts shall be going waste and if there is less play, hard steering would result in.

Type pressure: It should be as per specifications. Less or uneven pressure of air in the wheels shall result in hard steering and more tyre pressure shall lead to wobbling.

Play in wheel bearings: The wheel bearing should be properly adjusted. Less play shall result in hard steering and more play shall effect wheel alignment and lead to wheel wander.

Condition of king pins and bearings: The front portion vehicle load acts through the pins. If the pins are tight in the bushes, hard steering shall result in and if there is more play, wheel alignment shall be affected, which has great influence on the steering operation.

Wheel alignment: this relates to the relative position of wheels for obtaining a true and free rolling movement over the road. The smooth operation of steering depends much upon the wheel alignment.

Shock absorbers: Shock absorbers are filled with oil, which hydraulically dampen the suspension and prevent the wheels from bouncing. Due to this action, tyre-to-road contact is maintained over bumps and undulations. This in turn allows control of the vehicle to be maintained.

Introduction and Importance of Safe Steering

In discussions about road safety, not much emphasis is placed on the safe steering of a vehicle. As this is often regarded as a “common sense” activity we seldom pay enough attention to the skills required to perform this safely!

Steering safely is a fundamental skill we learn when studying how to drive, and is perhaps the skill that most people associate with operating a vehicle.

Cars are designed to run straight on a level or even slightly cambered road. This means that, if you let go of the steering wheel on a level road, the car should continue in a straight line for some distance before gradually veering to the left, because of the natural road camber

Because it looks really simple, many drivers often pay no importance to steering safely. But don’t make that mistake; virtually all the other driving skills like parking, cornering, and overtaking rely heavily on one’s ability to steer in a fluid but precise manner. Many fatal head-on collisions are directly related to our failure to steer our vehicles safely!

Over inflation/ Under Inflation

Over and under-inflation reduces tyre to road contact and shortens tyre life.
The tyre responds in the same manner to under inflation as to overloading.
The same applies to over inflation / under loading.
Over inflation / under loading: Reduces cushioning power of tyre. Tyre is more susceptible to impact, penetrations and abrasion. Reduced road-tyre contact. Negatively affects the handling characteristics of the vehicle. (Excessive centre wear.)

Under inflation / Overloading: The biggest single cause of a "burst" tyres. Under inflation cases excessive flexing of the tyre sidewall which leads to overheating and ultimately, casing break-up and tread separation. Reduced tyre-road contact leads to poor handling and faster wear. (Excessive shoulder wear.)
