Core Safety Specifications for Crane Operations: Build a Secure Defense Against Overturning, Overloading and Collisions

Anti overturning standard: Strengthen the foundation of the operation and eliminate the hidden danger of equipment overturning

Overturning is the most destructive safety accident in crane operations, often caused by substandard site conditions, non-standard operations, and abnormal equipment status. It is a key risk prevention and control measure on construction sites. Before starting the formal operation, the operator needs to conduct a comprehensive survey of the construction site to ensure that the working ground is flat and solid. The soft soil should be backfilled and compacted in a timely manner to avoid dangerous areas such as foundation pits, ditches, and slopes. The pad and roadbed board should be laid strictly according to the equipment requirements to ensure even stress distribution of the entire machine. During the operation, strictly control the lifting range and the elevation angle of the boom. It is forbidden to force the operation in severe weather such as strong wind and rainstorm. It is prohibited to operate the boom at extreme speed, suddenly rise and fall, and walk with load. At the same time, it is necessary to observe the tilting status of the equipment and the force on the support legs in real time. If any problems such as body deviation or suspended support legs are found, the machine should be stopped immediately for adjustment, and the risk of overturning should be avoided throughout the entire process of site, equipment, and operation to ensure the stability of the entire crane operation.

Anti overload regulations: strictly adhere to load standards and eliminate the risk of overloading operations

Overloading operations are the core cause of crane failures, structural damage, and safety accidents. Long term overloading operations can damage equipment steel structures, wire ropes, and hydraulic systems, significantly increasing the probability of failure. All lifting operations must strictly follow the rated load standards of the equipment. Operators must accurately calculate the weight of the lifted object, lifting equipment, steel wire ropes, and other accessories before starting the operation. It is strictly prohibited to estimate the load based on experience or blindly exceed the lifting limit. In response to the differences in working conditions between long and short arms and different amplitudes, it is necessary to match the rated lifting capacity accordingly to prevent violations such as small amplitude large load and large amplitude risky lifting. During homework, it is strictly prohibited to diagonally pull or lift heavy objects, drag heavy objects, or adjust the amplitude of the load. Lifting buried heavy objects, sticking heavy objects, and other situations are strictly prohibited. At the same time, the overload protection device and torque limiter are regularly checked to ensure that the safety protection device is sensitive and effective. Overloading operations are eliminated from the source, extending the service life of equipment while ensuring construction safety.

Anti collision regulations: standardize operating procedures to avoid collision accidents between human-machine equipment

The construction site has dense equipment, large personnel flow, and limited working space. The crane arm, hook, and lifted objects are prone to collide with surrounding buildings, machinery, and construction personnel, causing safety accidents. Before starting the homework, it is necessary to clear the obstacles within the homework radius in advance, designate a dedicated work warning area, arrange for a dedicated person to command and guide on-site, and prohibit unrelated personnel from entering the homework area. The operator must operate the equipment steadily and keep the crane arm and hook running at a constant speed and slow speed. It is strictly prohibited to rotate rapidly, start or stop suddenly, or swing the arm in a large range during operation. For multi device cross operation, adjacent buildings, and high-voltage line construction scenarios, it is necessary to plan the operation path in advance, reserve sufficient safety distance, and observe the surrounding environment dynamics in real time. At the same time, strictly implement standardized command commands, eliminate misoperation and blind operation, and comprehensively avoid equipment collision and human-machine collision accidents.

Full process compliance control: building a normalized safety operation system

The three safety points of crane overturning prevention, overload prevention, and collision prevention complement each other and are the core principles of engineering lifting operations, running through the entire process of equipment operation. A normalized safety control mechanism should be established at the construction site. Equipment inspection, site investigation, and condition assessment should be completed before the operation. Special personnel should be assigned to supervise, standardize operations, and implement real-time prevention and control during the operation. After the operation, equipment reset, hidden danger investigation, and maintenance should be carried out. Operators must hold certificates and be proficient in safe operating procedures under different working conditions. They should abandon the habit of lucky operations and strictly avoid all kinds of illegal operations. Standardized and regulated operation control can comprehensively eliminate various safety hazards in crane operations, ensuring efficient, safe, and orderly progress of engineering construction.
