Public works and mining machines are designed to withstand extreme working conditions. However, it is necessary to provide them with extra attention when winter is approaching.

Inspections are essential at any time of the year, but in winter it is 100% necessary due to the temperature drop. These lower temperatures and adverse weather conditions take their toll on equipment.

A periodic overhaul will keep the machine in the best possible condition to perform at its best for a longer period of time.
When carrying out the overhaul it is absolutely necessary to pay special attention to the following parts of the machine:

BATTERY

It is one of the components most affected in winter with the cold. Although it has been working during the summer it may be discharged suddenly due to the low temperatures. Do not forget to check the battery age, check its charge and replace it if necessary. A battery in good condition extends the life of other components such as the starter motor.

TIRE PRESSURE AND CONDITION

Tires are the only part of the machine in permanent contact with the ground.
The good or bad condition of the tire is affected depending on the weather, the possibility of snow, water or ice which directly impact on it, consequently influencing its correct operation.

Another check to take into account is the tire pressure as it directly affects the grip of the machine to the ground.

 

COOLANT FLUID

Coolant not only protects the system from freezing, but also prevents corrosion and avoids cavitation that leads to erosion of engine components. Coolant loses its properties over time. If it is not in good condition, it can result in engine overheating and costly breakdowns.

OILS

At low temperatures all oils become denser.
The viscosity of oils varies directly with temperature changes. It is essential to check and select the right oil for the temperature of the location in which the machine will work, so that the winter does not take its toll on the equipment.
It is  very important to check engine, hydraulic, servo-transmission and axle oil levels.
And always check and replace it if necessary

LIGHTS

In winter the bad weather conditions and the reduction of daylight hours increase the importance of all lights working properly. It is highly recommended to choose a lighting of high resistance, with greater durability and an optimal light quality for the darkest conditions.

 

WINDSHIELD WIPERS

Proper visibility is essential in the work carried out.

If the wiper blades do not clean the glass well or make noise, it is time to change them.

It is essential at any time of the year, but more so in autumn or winter as weather conditions are more adverse.

In addition, it is necessary to check and refill windshield washer fluid if necessary.

 

 

BRAKING

Stopping distances increase when the ground is not dry. For a safe work it is mandatory to check and verify the condition of the brakes.

Regardless of the time of year, it is absolutely necessary to check the brakes; the operator’s safety is at stake.

 

HEATING

In addition to the comfort that heating brings to the cabin, it also helps to demist windows in cold weather. Due to the lack of use in summer, the radiator could be clogged, so it is imperative to include it in the winter overhaul.

Do not forget to change the cabin filters as well.

 

LUBRICATION SYSTEM

Low ambient temperatures influence the lubrication capacity.

Therefore, it is important to choose the right consistency of grease depending on the temperature of the area.

 

A good grease not only dissipates heat and reduces wear of linkages, shafts, spiders and bearings, but also protects them against water and corrosion during the winter months.

 

UNDERCARRIAGE

In winter, the terrain conditions are very changeable. The good condition of the machine’s undercarriage, whether made of steel or rubber, ensures maximum control at any time when carrying out the work.

 

BELTS AND TENSIONERS

Belts are one of the parts with the highest risk of deterioration, not only due to the passage of time and wear, but also due to temperature changes that may cause crack or harden, causing noise during operation or breakages which lead to more costly repairs.

It is very important to check their condition and tension, and replace them if necessary.
