What are the precautions for the safe operation procedures of concrete laser leveling machines?

The core of the safe operating procedures for concrete laser leveling machines is "personnel protection, equipment control, environmental avoidance, and emergency response." Focus on the following four key areas to ensure human and machine safety and construction compliance:

1. Personnel Safety: Mandatory Protection + Standardized Operations

Pre-Job Requirements

Operators must undergo professional training and be familiar with the equipment's structure (laser system, hydraulic system, vibrating mechanism) and operating buttons. Operating the equipment without a license is strictly prohibited. Support personnel must understand the equipment's operating range and avoid entering hazardous areas.
All personnel must wear hard hats and non-slip, insulated shoes during operation. When working with concrete, wear waterproof gloves. When cleaning the equipment, wear protective clothing to prevent burns from cement slurry splashes.

Operational taboos

It is strictly forbidden to adjust the laser transmitter/receiver while the machine is operating (this requires shutting down the machine and disconnecting the power supply). Avoid direct laser light into your eyes (the strong light may cause blindness).
Do not stand under the scraper or vibrator or inside the machine's tracks/tires to prevent hydraulic system failure from causing components to fall or the machine to overturn.
Do not be distracted during operation (e.g., answering or making phone calls). Two people working together must maintain communication (using hand gestures or a walkie-talkie) to avoid accidental collisions.
 

2. Equipment Safety: Startup Inspection + Operation Control

Items to check before starting the machine

Inspection Area	Inspection Items and Standards	Purpose
Laser System	The transmitter/receiver is fully charged, calibrated correctly, and free of signal interference.	Avoid elevation errors and equipment misjudgment
Hydraulic System	The oil pipes are leak-free and the hydraulic oil level is within the upper and lower limits.	Prevent hydraulic failure (such as scraper jamming)
Power and Transmission	The engine oil and coolant levels are normal, and the tires/tracks are undamaged.	Ensure stable equipment operation
Safety Devices	The emergency stop button (red) is responsive, and the warning lights and horn are functioning properly.	Enable rapid shutdown in emergencies

Operational Controls

After starting the equipment, allow it to idle for 1-2 minutes to confirm that the vibrator and scraper are operating smoothly without unusual noise or jamming before entering the work area.
Strictly control the travel speed to 0.5-1.5 m/min. Reduce speed when turning (≤ 0.5 m/min) to avoid rollover caused by high-speed turns.
Overloading is strictly prohibited (e.g., concrete pile thickness exceeds the maximum handling capacity of the equipment) to prevent motor overload and scraper deformation.
 

3. Environmental Safety: Avoid Risky Scenarios

Work Environment Taboos

Do not operate on rainy days or when the base is flooded. This can reflect the laser signal (causing elevation errors) and potentially short-circuit the equipment's electrical system.
Avoid areas with strong electromagnetic interference (such as those near large transformers or welding machines) to prevent laser signal interference and equipment loss of control.
For nighttime operations, ensure adequate lighting (≥50 lux) and display warning signs around the laser transmitter to prevent collisions.

Site Protection

Warning tape or guardrails must be installed at the edges of the work area. Especially when working at height (such as pouring floors), edge protection (such as scaffolding) must be checked to prevent equipment from slipping or falling.
The laser transmitter must be mounted on a stable, unobstructed support (≥1.5m in height) and supervised by a designated person. Unauthorized movement is prohibited.
 

4. Emergency and Closing: Prompt Risk Management

Emergency Response

In the event of an emergency (such as laser signal interruption, unusual equipment noise, or hydraulic leakage), immediately press the emergency stop button, disconnect the power supply, and troubleshoot the problem. Do not operate with the equipment in a faulty state.
If equipment overturns and causes injury, evacuate personnel to a safe area, call emergency services (such as 120), secure the scene, and report the incident to the responsible person.

Finishing Safety

After completing the operation, first shut down the laser system, then the power supply, and use a high-pressure water jet to clean any remaining concrete (do not use water directly on electrical components).
The equipment must be parked away from slopes and edges, with the handbrake engaged and triangular wood placed to prevent rolling. The laser transmitter and receiver must be stored in a moisture-proof box to prevent damage.
 

Core Compliance

All operations must comply with the "Technical Regulations for Safety in the Use of Construction Machinery" (JGJ 33) and the "Concrete Structure Construction Quality Acceptance Code" (GB 50204). Regular (every three months) professional verification of the equipment's safety devices and laser accuracy should be performed to ensure long-term compliance.
