In the field of construction, as an efficient vertical transportation and operation platform, the safe use and standardized management of high-altitude operation hoists are crucial. To ensure construction safety and prevent accidents, strictly complying with the installation requirements and usage specifications of hoists is the core responsibility of all relevant units and personnel. This article will elaborate on the safety points throughout the entire process of high-altitude operation construction hoists, from installation preparation, process control to daily use and maintenance.

 

The safety of hoists begins with scientific preliminary planning and adequate installation preparation. Firstly, the design of the hoist installation form must strictly follow the provisions of the product instruction manual and relevant national or industry standards to ensure that its structural selection matches the construction requirements. Secondly, it is necessary to comprehensively consider the characteristics of the building structure, on-site usage requirements, and specific installation conditions to optimize the layout design of the hoists, and draw detailed layout plans, specifying the position, quantity, and operation range of each hoist to avoid mutual interference or potential safety hazards.

 

Installation personnel are the first line of defense for the safe installation of hoists. Before the start of installation work, all installation personnel must receive systematic professional training to ensure that they fully understand the structural characteristics of the hoist to be installed, detailed operating specifications, and crucial safety precautions. At the same time, before installation, all components of the hoist must be checked one by one to confirm that the main structure, wire ropes, safety devices, and other key components as well as all accessories are in good condition, without damage, deformation, or functional failure.

 

 

The installation process of the hoist is a critical link in safety control and must be carried out in strict accordance with established operating procedures and technical requirements. During installation, special attention should be paid to the following details: The installation of tension ropes and reinforcing ropes should meet the design requirements to ensure uniform force and firm connection; the life safety rope, as the last barrier to protect personnel's lives, must be independently set up and securely fixed; the threading, fixing, and pre-tightening of wire ropes should be correct to avoid twisting, knotting, or excessive wear; the connecting bolts of all structural parts must be tightened in place to prevent loosening; the weight of the counterweight should meet the design regulations and be firmly fixed to prevent overturning; the installation position and quantity of the counterweight hammer should be accurate to ensure the balance and stability of the hoist; the front support and possibly used wall-riding bracket and other supporting structures must be installed stably, with a solid and reliable bottom bearing surface to meet the bearing capacity requirements.

 

 

After the hoist is installed, it cannot be put into use immediately. The general contracting unit must take the lead in organizing a joint acceptance with the property rights unit, the user unit, and the supervision unit. The acceptance should be based on relevant standards and design documents to conduct a comprehensive inspection of the installation quality of the hoist, the effectiveness of safety devices, and the connection of various components, and truthfully fill in the acceptance form. Only after the acceptance is qualified and confirmed by signature can the hoist be officially put into use.

 

When the construction requires hoist displacement or the hoist needs to be dismantled after the operation, it must also be operated in strict accordance with the reverse order of the original installation process. It is strictly forbidden for any unit or individual to私自 conduct displacement, dismantling, or modification to ensure that the process is safe and controllable.

 

 

The professional quality of operators is directly related to the safety of hoist use. All hoist operators must receive special safety technical training, pass the assessment, and obtain a valid "Hoist Construction Operation Certificate" before they can work.

 

In daily use, operators must strictly abide by the following regulations: correctly wear and use personal protective equipment such as safety helmets and safety belts, and ensure that safety devices (such as safety locks, limiters, etc.) are in normal working condition; it is strictly forbidden to overload the hoist or carry flammable, explosive, and other dangerous goods; it is strictly forbidden to force operation when the hoist is faulty. Once any abnormal sound, vibration, or functional failure is found, the use should be stopped immediately and professional personnel should be reported for inspection and maintenance in a timely manner; before daily operation, professional personnel should conduct routine safety inspections on the hoist to confirm that it is correct before allowing use; the hoist is strictly forbidden to be used as a vertical transportation tool for carrying materials or personnel; its power supply box must meet the electrical safety requirements of "one machine, one switch, one leakage protector, one box" to ensure electrical safety; to ensure operation visibility and safety, the hoist is prohibited from being used at night; according to the construction scale and the number of hoists, a sufficient number of professional managers and maintenance personnel should be in proportion to ensure effective supervision of the hoist use process.

 

 

To ensure the long-term safe and stable operation of the hoist, regular inspection and maintenance are indispensable. A sound hoist inspection and maintenance system should be established, specifying the inspection cycle, content, and responsible person. Regular comprehensive inspections, lubrication, and adjustments should be carried out on key parts of the hoist such as structural parts, wire ropes, safety locks, and electrical systems to timely detect and eliminate potential faults, replace aging or damaged parts, and ensure that the hoist is always in good technical condition.

 

In conclusion, the safety management of high-altitude operation construction hoists is a systematic project that requires strict control from all links including design, installation, acceptance, use, and maintenance. All relevant units and personnel must attach great importance to it, strictly implement various safety specifications, and integrate safety awareness throughout the entire construction process to effectively prevent accidents and ensure the life safety of construction personnel and the smooth progress of the project. During specific operations, it is essential to combine the actual on-site conditions and strictly follow the latest national and local laws, regulations, and standards.
