Construction elevator common safety hazards
To ensure the safety of the construction elevator, it is necessary to understand the common safety hazards.
Hidden dangers during installation, disassembly, and addition
1. Temporary employment of non-professional dismantling and qualified personnel;
2. Safety education and safety technology are not provided to the operators;
3. The installation quality is not high, the inspection is not in place, especially the installation accuracy of the rail frame is poor, the verticality is seriously exceed the allowable deviation, or the installation clearance of the machine is exceeded, which will leave great danger to the safe operation of the construction elevator.
4. The necessary acceptance and test procedures have not been carried out. If the test is not qualified, the newly installed construction elevator will be put into use rashly, which will easily lead to various accidents.
Hidden dangers of the construction hoist itself
1. Overloading (overload protector failure) poses a serious threat to the safe operation of construction elevators.
2. The service life of the main components exceeds the allowable life of the whole machine.
3. Daily inspection found that there are more problems with the attached wall.
4. Common cage door interlock failure conditions:
5. There are problems with the floor protection door and the unloading platform:
6. Other problems: After the rail frame is added, the floor is raised, and the communication device is not installed in time, which makes the upper and lower personnel unable to contact, which not only affects the construction progress, but also brings hidden dangers to safety. In addition, there is a separate installation of grounding protection and lightning protection devices according to regulations, and the ground entrance and exit protection sheds do not meet the requirements.
Security risks caused by illegal operations
The construction elevator is an indispensable manned cargo loading machine on the construction site. During the use process, it must correctly understand its potential safety hazards and take relevant preventive measures in time to avoid “safety hazards” becoming “safety accidents”.
