We are glad to send you the 14th and last INFO MANEJO's issue of the year, where you will learn how to drive with a trailer with inertial brakes, to maintain the air conditioning and
We also invite you to visit our web site where you will find previous INFO MANEJO issues, in their Spanish and English versions.

 Driving with overspeed brakes' trailers
|
Trailers that weigh more than 750 kg must count with overspeed brakes. When a light vehicle carries a trailer, this kind of brakes are important for their safety, because if the tractor brakes using only its service brake and the trailer doesn't have a brake of its own, the trailer with its own inertia, will push the tractor vehicle due to the fact that they would be driving at the same speed. Hence, a velocity difference would appear related to the trailer's mass that exceeds the tractor's braking capacity. This indicates that, at least, the braking distances would increase significantly. The inertia force is generated by the trailer's tendency to keep the vehicle going in the same velocity it had before.
To prevent the trailer from pushing and from the consequences of lack of control, brakes of the overspeed type are used, as the law in force demands. Overspeed brakes function when the vehicle tractor's velocity diminishes. The pushing is generated in the trailer, and it acts over the drawbar's brake cylinder, producing an efficiently proportioned braking, without blocking the wheels.
Warning: When driving in reverse, the pushing generated when the tractor vehicle brakes has the opposite direction to the pushing previously mentioned, thus, it doesn't activate the trailer's overspeed brake. This is why the precaution measures should be maximized, because we won't count with the trailer's braking action. It's advisable to drive at a very low speed when going in reverse, always a lower velocity that when driving in reverse in normal situations -with no trailer-. Plus, we should bear in mind that when we are going back, the trailer will answer to the turning manoeuvres in an opposite direction from the tractor.

Air conditioning maintenance
|
The air conditioning system is no longer considered like just a comfort device, because it has turned into an important safety device. In high temperature periods it's the driver's allied, because it reduces his fatigue and prevents the excessive heat from affecting his concentration, thus, it improves his performance.
That it's why it's important and necessary to maintain the system in a good functioning state.
Some recommendations:
+ Every year check if the system has enough coolant gas.
+ Do not modify nor obstruct the air distribution conducts.
+ Maintain the belts in a good state. To replace them we should verify: the mileage and how much time they were used. Manuals say when it's necessary to change them, nevertheless we can prevent them from cutting by checking periodically if they are ripped or if there are loose threads that mean that the belts concluded with their service life.
+ Keep the filters and air grilles clean. An inadequate air circulation might freeze the radiator, diminishing its performance.
+ Turn it on all year long to maintain the circuit. In winter it can be used to remove the steam from the glasses, complementing it with the heating system.
+ Regularly, select the option to change the air with the exterior and do not block the entrance of new air during long periods. Remember that bad ventilation reduces the quantity of oxygen and can cause drowsiness.
Warning: When functioning, the air conditioning consumes an important amount of the engine's power, affecting its performance. It's safe and useful to turn it off when overtaking a vehicle or when we drive up slopes.

Where to start from
|
In all our INFO MANEJO articles we have tackled different points that must be bared in mind when managing our company's vehicles, focusing on the safety ones. But, how can we do to avoid failing when trying to implement a vehicle safety management?
As in many management systems, wishing our starting point to be a complete and finished system that we will implement from scratch, will imply, besides of a big effort from where we will have low rate of benefits, something impossible to carry out because of the multiplicity of processes to be done. For this reason, an incremental or spiral model is the best solution, where we start from aspects that belong to a general long term plan.
Vehicle management should be thought as a solution to existent problems, with the objective to improve permanently our fleet's use. The beginning of our plan should be based on historic data. E.g. grade the main accident causes. This will lead us to focus first on people or vehicles, but not on both at the same time. Then, we will step forward with other subjects although we didn't complete the previous ones, which will be improved and finished in other stages during time. From each advance we will obtain customized formal procedures, more specific and easy to grant its compliance. These procedures will be the base of our future vehicle policy, which will be built with our managers' experience and the advising of hired specialists.
All in all, a road of not failing when trying must be:
+ draw an evolving plan, where periodically we touch each management subject
+ start with the critical factors
+ implement proven and existent solutions in similar companies, but seeking through our specific activities
+ formalize our action in possible application procedures
+ build a vehicle management policy
+ return to each subject (personnel, vehicle, environment) and make them evolve
