Points To Be Paid Attention To When Working With Small Cranes Under High Temperature In Summer

Working with small cranes during the scorching summer months requires extra caution and attention to ensure both the maintenance of the crane and the safety of the operator. The combination of high temperatures and heavy-duty operations can lead to increased risks, such as decreased inflation coefficient, lubricating oil deterioration, machine parts burning, and compromised braking performance, which can result in frequent accidents. To mitigate these risks and ensure smooth operations, certain precautions need to be followed when operating small cranes under high temperature conditions in summer.

1. Deterioration and Burning of Lubricating Oil:

High engine temperatures cause the anti-oxidation stability of lubricating oil to deteriorate. This leads to increased thermal decomposition, oxidation, and polymerization of the oil, which can impact its performance.

2. Contamination of Lubricating Oil:

Dry and dusty air, as well as moist air, can introduce contaminants into the engine oil pan through the air intake system and crankcase vents. This pollution compromises the quality of the lubricating oil, leading to further deterioration.

3. Evaporation and Burning of Lubricating Oil:

As the lubricating oil passes through overheated areas, such as cylinder walls, pistons, piston rings, journals, and oil bottoms, it is prone to evaporation and burning. This process accelerates wear and tear on engine parts.

4. Carbon Deposits and Colloids:

High engine temperatures contribute to the formation of carbon deposits and colloids on various engine parts, including the piston top, combustion chamber walls, and valve heads. These deposits hinder heat dissipation and hasten the damage to engine components.

5. Thinning of Engine Oil:

Elevated engine temperatures cause the engine oil to become thinner, resulting in decreased oil pressure and reduced formation of a lubricating oil film. This, in turn, accelerates wear on engine parts.

6. Tire Maintenance:

When it comes to tire maintenance, it's crucial to consider wear, road conditions, and driving mileage rather than solely relying on the age of the tires. It's recommended to replace tires based on wear and working conditions to ensure the balance and safety of the vehicle. Enlarging the hub excessively can negatively impact braking effectiveness, while using excessively wide tires may affect fuel consumption and braking performance. Whenever possible, tires should be used and replaced in pairs to maintain vehicle balance.

7. Outrigger Usage:

Outriggers play a vital role in providing greater support span for the crane during lifting operations. It is essential to ensure the outriggers are properly positioned and secured. While they are lightweight due to space constraints, their lateral support distance may be limited. This emphasizes the importance of ensuring stable lateral support for the crane during operation, without compromising its lifting capacity or mobility.

By paying close attention to these points and implementing proper maintenance and safety measures, operators can mitigate the risks associated with working with small cranes under high temperature conditions in summer. This will not only enhance the longevity and performance of the crane but also ensure the safety of all personnel involved in the operations.
