Several inspections for truck-mounted crane winter maintenance

Winter maintenance of truck-mounted cranes is a crucial task that demands attention to multiple aspects, especially the inspection of easily worn parts. These inspections are essential to ensure the safe and efficient operation of the crane during the cold winter months. Let’s take a closer look at the inspections of easily worn parts for truck-mounted crane winter maintenance.

The appearance of a truck-mounted crane not only affects its aesthetic appeal but also provides an indication of its overall condition. Inspecting the appearance includes examining the vehicle body surface and all visible parts.

First and foremost, thoroughly washing the vehicle is a necessary step. A clean vehicle allows for a more detailed inspection as dirt and grime can mask potential issues. After washing, take a walk around the vehicle twice and carefully observe the paintwork. Look for scratches, dents, or any other signs of damage. Even small scratches can lead to rust formation over time if not addressed promptly.

Scratches on the paintwork can occur due to various reasons, such as accidental contact with other objects or exposure to harsh weather conditions. In winter, when road salt and ice can be abrasive, the risk of paint damage is even higher. If left unaddressed, these scratches can allow moisture to penetrate the metal body, leading to rust and corrosion.

For example, imagine a truck-mounted crane parked outdoors during a winter storm. The combination of snow, ice, and road salt can cause small particles to scratch the paint as the wind blows them against the vehicle. Over time, these scratches can deepen and become more visible, potentially compromising the integrity of the body.

In addition to scratches, check for any other damage to visible parts such as mirrors, lights, and bumpers. These components are essential for safe driving and proper operation of the crane. Any damage to them can affect visibility or functionality.

After a long period of use, a particular part in the engine compartment of the truck-mounted crane requires emphatic inspection – the “air filter.” The air filter plays a crucial role in protecting the engine by filtering out dust, dirt, and other contaminants from the incoming air.

If the vehicle owner frequently drives on roads with more dust than in the city, the air filter may absorb a significant amount of dust during this time. When dust enters the engine, it can cause wear and tear of various engine parts. This can lead to reduced engine performance, increased fuel consumption, and potentially costly repairs.

Moreover, if the air filter becomes blocked, it will restrict the air intake, resulting in insufficient oxygen for proper combustion. This can cause the engine to lose power and run less efficiently.

To check the air filter, remove it carefully from its housing. Inspect it for signs of excessive dust accumulation, clogging, or damage. If the filter is dirty, it can be cleaned or replaced depending on its condition. In some cases, a simple cleaning with compressed air may be sufficient. However, if the filter is severely clogged or damaged, it should be replaced with a new one.

For instance, suppose a truck-mounted crane is used on a construction site with a lot of dust. Over time, the air filter can become saturated with dust, reducing its effectiveness. If not checked and replaced when necessary, the engine may suffer from poor performance and increased wear.

Tires are one of the most critical components of any vehicle, and for a truck-mounted crane, they play an especially important role in ensuring stability and safety. After a long period of bumping and wear, the tire positioning may become ineffective.

The most obvious characteristics of improper tire positioning are vehicle deviation and bouncing. If the vehicle starts to pull to one side while driving or experiences excessive bouncing, it is a sign that the tire alignment or balance may be off.

Deviation can be caused by uneven tire wear, improper inflation, or damage to the suspension system. Bouncing can indicate problems with the tires themselves, such as low air pressure, damaged belts, or worn shock absorbers.

In such cases, it is essential to have the tires inspected by a professional. They can check the tire pressure, alignment, and balance and identify any issues that need to be addressed.

For example, imagine a truck-mounted crane driving on rough winter roads. The constant impact and stress can cause the tires to wear unevenly, affecting their performance. If left uncorrected, this can lead to poor handling, increased fuel consumption, and a higher risk of accidents.

Regular inspection and replacement of engine oil are crucial for the proper functioning of the truck-mounted crane‘s engine. Engine oil lubricates the moving parts of the engine, reducing friction and wear. In winter, the engine oil needs to be able to flow smoothly at lower temperatures to ensure proper lubrication.

Check the engine oil level regularly using the dipstick. If the level is low, add the appropriate amount of oil. When replacing the engine oil, make sure to drain the original oil completely. Any old or contaminated oil left in the engine can cause damage and reduce performance.

After draining the old oil, add new engine oil that meets the manufacturer’s specifications. Use the correct viscosity grade for the winter climate to ensure proper lubrication.

For instance, if the engine oil is not changed regularly or if the wrong type of oil is used, it can lead to increased engine wear, reduced fuel efficiency, and potential engine failure.

The chassis of a truck-mounted crane is subjected to a lot of stress and abuse, especially during winter when road conditions can be harsh. If there are phenomena such as abnormal noise from the chassis, shaking of the steering wheel, or oil stains at the parking position of the vehicle, it indicates that the chassis may have been damaged.

After road obstacles scratch the chassis, some parts of the chassis can become deformed. Components such as the upper and lower swing arms, left and right steering tie rods, and other suspension parts are particularly prone to deformation. Even slight collisions can cause minor leaks in the oil pan or transmission oil pan.

To inspect the chassis, look for any signs of damage, such as bent or cracked parts. Check for loose bolts or connections. If there is abnormal noise or shaking, have a professional mechanic inspect the suspension and steering systems.

For example, suppose a truck-mounted crane encounters a large pothole on a winter road. The impact can damage the chassis, causing parts to bend or break. If not detected and repaired promptly, this can lead to poor handling, increased wear on tires and other components, and a potential safety hazard.

The brake system is one of the most critical safety features of any vehicle, and for a truck-mounted crane, it is essential for ensuring safe stops and preventing accidents. Visually inspect the surface of the brake disc through the aluminum alloy wheel rim of the tire.

The surface of the brake disc should be smooth. If there are obvious grooves on the disc, it may indicate a problem. This can occur when the vehicle is driving on a gravel road, and some small gravel gets stuck between the brake disc and the fender. The continuous rubbing of the gravel against the disc can create grooves.

In such cases, when the vehicle is running, a “clanging, clanging” sound may be heard. In some instances, a screeching sound can also be heard when braking. These sounds are warning signs that the brake system needs attention.

Have a professional mechanic inspect the brake system if you notice any unusual sounds or signs of wear on the brake discs. They can check the brake pads, calipers, and other components to ensure they are in good condition.

For example, if the brake discs are severely grooved, it can reduce the effectiveness of the brakes and increase stopping distances. This can be extremely dangerous, especially in winter when roads are slippery.

The vehicle glass is not only important for visibility but also plays a role in the safety and comfort of the driver and passengers. Not all problems with vehicle glass can be solved by simply rinsing with clean water.

For example, if oil gets stuck on the glass, it may not be visible to the naked eye. However, it can greatly reduce the efficiency of the windshield wiper. At this time, degreasing cleaners must be used to remove these oils.

There can also be permanent scratches on the windshield caused by gravel mixed in the windshield wiper or wounds caused by stones hitting the glass. These scratches can affect visibility and can be a distraction for the driver.

Inspect all the vehicle glass carefully for cracks, chips, scratches, and other damage. If there are any significant issues, have the glass repaired or replaced as soon as possible.

For instance, imagine driving a truck-mounted crane in winter with a cracked windshield. The cold temperature can cause the crack to expand, further reducing visibility and increasing the risk of the glass shattering.

In conclusion, winter maintenance of truck-mounted cranes requires thorough inspections of easily worn parts. By paying attention to these inspections and addressing any issues promptly, vehicle owners can ensure the safe and efficient operation of their cranes during the winter months. Regular maintenance not only extends the lifespan of the vehicle but also helps prevent costly repairs and potential safety hazards.
