What are the safety inspection standards for construction hoist?
construction hoist are also called construction elevators.Generally,it refers to a transportation vehicle that vertically transports pedestrians or building materials on construction sites. The total number of construction elevators in the world exceeds 8 million, which is the most used vertical transportation of people and goods in the contemporary construction industry.
As a construction machine that uses a hanging cage to carry people and loads and transports them up and down along the guide rails,construction hoist are widely used in construction due to their simple structure,fast lifting and smooth transmission.With the continuous increase of high-rise buildings,the use of elevators has also increased rapidly,leading to frequent occurrence of malignant accidents.The main reason is the lack of scientific management and effective preventive measures.So what are the safety inspection standards for construction elevators?
Anti-fall safety device
The construction hoist relies on anti-fall safety devices to eliminate the occurrence of cage falling accidents and ensure the safety of the occupants.Therefore,the factory test of the anti-falling safety device is very strict,and the lifts used on the construction site must undergo a fall test every three months and an annual test.The quality of the anti-falling safety device can only be judged through testing and inspection.It is impossible to determine whether it is good or bad in daily operation.
The safety switches of the lift are all designed according to safety requirements.In some construction sites, in order to save trouble, some limit switches are manually cancelled and short-circuited or damaged and not repaired in time, which is equivalent to canceling these safety lines of defense and planting hidden accidents.
Example:The hanging cage needs to be loaded with long things,and the hanging cage cannot fit inside and needs to be extended out of the hanging cage, and the door limit or top door limit is artificially canceled.In the case of imperfect or incomplete safety facilities, people still carry people,This kind of illegal operation is joking with the lives of workers.
Wear and replacement of gears and racks
The working environment of the construction site is harsh, cement, mortar, and dust cannot be eliminated. The gears and racks are ground each other, and the teeth are still in use after they are sharpened. This should be taken seriously. Many "old" gears and rack elevators on the construction site are still in overdue service. For safety reasons, new parts must be replaced.
The buffer on the construction hoist is the last line of defense for the safety of the construction hoist. First,it must be installed; second, it must have a certain strength,can withstand the impact of the hoist's rated load, and serve as a buffer. And many construction sites, although some have installations, but they are not enough to play a buffer role, and some construction sites have no buffers at all. This is extremely wrong, and this last line of defense cannot be underestimated.
Floor parking safety protection door
Each parking floor of the construction hoist shall be equipped with parking safety protection doors.If it is not installed as required, construction workers waiting at high places are prone to accidental fall accidents.When setting the parking safety protection door,the height of the safety protection door should be no less than 1.8 meters, and the landing door should have an interlocking device.The protection door cannot be opened when the cage is not at the parking position to ensure the safety of operators.On the construction site, people waiting for the construction elevator can open the safety protection door at any time. This is very dangerous and should be taken seriously.
