Full analysis of loader crane operation: the key to safe and efficient operation
Posted: Mar 12th, '25, 23:06
As an important mechanical equipment in engineering operations, the standardization of the operation of loader cranes is directly related to the safety and efficiency of the operation. Whether it is for novices who are new to this field, seeking "Loader Crane Novice Operation Guide", or experienced veterans facing complex working conditions, it is crucial to understand the key points of its operation. Correct operation procedures and skills can give full play to the performance advantages of loader cranes and ensure the smooth progress of the project.
Careful preparation before operation
Before starting the loader crane, comprehensive and meticulous preparation is essential. The first is equipment inspection, involving "Loader Crane Daily Pre-Operation Inspection Points". The operator needs to check the vehicle in all directions to check whether the tire pressure is sufficient and whether there is obvious wear or damage, which is related to the stability and safety of the crane during driving. At the same time, check the appearance of the crane to see if there is any deformation, cracks, etc. on the body, especially the key parts such as the boom and outriggers. Any slight damage may cause serious problems during operation.
Inspection of the hydraulic system is also a key link. Check whether the hydraulic oil level is within the normal range, whether the oil is clean, and whether there is turbidity or emulsification. The hydraulic system is like the "blood vessels" of the loader crane. The quality and level of the hydraulic oil directly affect the power transmission and smooth operation of the crane. In addition, the electrical system should not be ignored. Check whether the battery power is sufficient, whether the lines are firmly connected, and whether there is any risk of damage or short circuit to avoid equipment loss of control due to electrical failure during operation. Only after completing these comprehensive and detailed inspections and ensuring that the equipment is in good condition can the next step be carried out.
Correct operation of starting and running
When starting the loader crane, follow the standardized process. Insert the key, turn the ignition switch to the start position, and start the engine. In the early stage of engine startup, pay close attention to the various indicators and parameters on the dashboard, such as engine speed, oil pressure, water temperature, etc. The engine speed should be stable within the normal idle range, and the oil pressure and water temperature should also gradually increase within the specified standard values. After the engine is preheated for a period of time and all parameters are stable, subsequent operations can be carried out. This is very important for "loader crane engine cold start protection".
When preparing for lifting operations, first drive the loader crane to a suitable working position to ensure that the ground is solid and flat. Lower the outriggers and adjust the extension length of the outriggers to keep the crane in a horizontal and stable state. This is the basis for ensuring lifting safety. The stability of the outriggers directly determines the crane's anti-overturning ability during operation. In the "Loader Crane Outrigger Operation Skills", it is emphasized that the support force and extension range of the outriggers should be reasonably adjusted according to different ground conditions and lifting weights. When starting the lifting and rotating operating device of the crane arm, operate the control handle slowly to avoid sudden acceleration or emergency stop to prevent the cargo from shaking or even falling.
Operation points in different operating scenarios
In conventional cargo lifting scenarios, operators need to accurately judge the weight, shape and center of gravity of the cargo. According to the "Tips for Lifting Cargo of Different Shapes with Loader Cranes", cargo with regular shapes and clear center of gravity can be directly lifted, but the connection between the hook and the cargo must be firm and reliable. For cargo with irregular shapes and difficult to determine center of gravity, auxiliary tools such as ropes and slings are needed to reasonably bundle and fix the cargo so that the center of gravity is in a stable state before lifting. During the lifting process, the crane arm must always be kept stable to avoid large swings.
When working in a narrow space, the "Tips for Loader Crane Operation in a Narrow Space" is particularly critical. Due to limited space, the operating range of the crane is greatly restricted. At this time, the operator should operate the extension and rotation of the crane arm more carefully, make full use of the flexibility and maneuverability of the crane, and use small amplitude and multiple frequency operations to gradually complete the lifting task. At the same time, pay close attention to the distance between the crane and surrounding obstacles, and arrange special personnel to direct when necessary to ensure the safety of the operation.
Safety Precautions in Operation
Safety is always the top priority of loader crane operation. Operators must strictly abide by the operating procedures and overloading is strictly prohibited. Each loader crane has its specified rated lifting capacity. Overloading can easily lead to serious accidents such as crane tipping and cargo falling. During operation, you must always stay focused and avoid fatigue. Long-term continuous operation can easily lead to slow response and misjudgment of operators, increasing the risk of accidents.
In addition, pay attention to keeping a safe distance from people around you and set up obvious warning signs to prevent unrelated people from entering the operation area. In severe weather conditions, such as strong winds, heavy rain, and heavy fog, operations should be stopped because these weather conditions will seriously affect the stability of the crane and the operator's line of sight. Strictly following these safety precautions is the basis for ensuring the safety of loader crane operation and achieving efficient operation.
The operation and use of loader cranes covers many aspects such as pre-operation preparation, start-up operation, response to different operation scenarios, and safety assurance. By mastering these comprehensive and detailed operating points, whether a novice seeks the "Operation Guide for Newbies of Loader Cranes" or an experienced operator facing complex working conditions uses the "Operation Skills for Loader Cranes in Small Spaces", etc., they can operate loader cranes more safely and efficiently, give full play to their important role in engineering operations, and provide strong support for the smooth progress of various engineering construction.
