Construction Precautions for Concrete Laser Leveling Machines in Extreme Temperature Environments

In extreme temperature environments (high or low), the performance of concrete laser Leveling machines and the setting state of concrete are significantly affected. Based on professional guidance from Vanse Machinery, the following are key precautions for construction in extreme temperature environments:

I. Construction in High-Temperature Environments (Generally referring to temperatures above 35°C)

In high-temperature environments, rapid water loss from the concrete and overheating of the hydraulic system are the biggest challenges.

Hydraulic and Power System Cooling:

Oil Selection: High viscosity index hydraulic oil (such as No. 68 hydraulic oil) must be used to prevent the oil from thinning and causing insufficient pressure due to high temperatures.

Radiator Cleaning: Inspect and clean the cooling fins of the engine and hydraulic system before daily operation to prevent dust and cement slurry from clogging them and affecting heat dissipation.

Intermittent Operation: Under extremely high temperatures, avoid continuous operation of the machine under overload; if necessary, take measures to stop the machine and cool it down.

Concrete Slump Control:

High temperatures cause concrete slump to drop extremely quickly. During construction, the travel speed of the laser Leveling should be strictly controlled to ensure leveling is completed before the concrete initially sets.
Substrate Moistening: The substrate (base) must be thoroughly moistened before construction to prevent it from absorbing moisture from the concrete, which could lead to shrinkage cracks in the underlying layer.

Preventing laser interference:

High temperatures can cause ground-level heat waves (heat waves) to refract the laser beam, resulting in a "drift" phenomenon.
Solution: Erect the laser transmitter in the highest and coolest possible location, and minimize the distance between the transmitter and receiver (ideally within 30-40 meters) to ensure accuracy.

II. Construction in Low-Temperature Environments (Generally referring to temperatures below 5°C)

Low temperatures can affect machine start-up performance and the hardening speed of concrete.

Machine Preheating and Lubrication:

Low-viscosity oil: Replace with low-temperature special engine oil (such as 5W-40) and low-pour-point hydraulic oil (such as No. 32 aviation hydraulic oil) to prevent oil solidification that could damage the pump head.
Start-up preheating: Do not operate at high speed immediately after starting. Allow the machine to idle for 10-15 minutes until the hydraulic oil temperature rises above 20°C before beginning leveling operations.

Battery and electronic component protection:

Batteries experience a significant capacity reduction at low temperatures. After construction is completed, the batteries and laser emitter should be removed and stored in a warm indoor environment to prevent power loss or freezing and cracking of the LCD screen.

Concrete antifreeze:

When using a laser Leveling, ensure the concrete temperature upon placement is not lower than 5°C.
Post-screing treatment: After the machine completes the screing, immediately cover the concrete with plastic film and insulating straw mats to prevent freezing and subsequent surface sanding or cracking.

III. Key Recommendations for Extreme Environments

Laser Accuracy Verification: Drastic temperature changes can cause thermal expansion and contraction of precision components inside the laser emitter. It is recommended to recalibrate the reference level every 2-3 hours of continuous operation.
Seal Inspection: Extreme high temperatures accelerate seal aging, while extreme low temperatures make seals brittle. Special attention should be paid to checking all hydraulic cylinder joints for leaks.
Personnel Safety: In extreme environments, heatstroke prevention and frostbite protection for construction personnel are equally important.

If you are carrying out special flooring construction (such as cold storage floors or outdoor plazas) in extremely cold regions (such as below -10°C) or tropical regions, it is recommended to contact WanShi Machinery's technical support to obtain an oil change list and parameter setting guidance for specific machine models.
