Comprehensive Interpretation of Suspended Platform Safety Standards and On - site Hidden Danger Prevention

Next, we will conduct an in - depth discussion on the safety standards of suspended platforms, covering multiple key aspects such as safety locks and life ropes. In the process of understanding these standards, we will have a clearer understanding of the importance of suspended platform safety and how to ensure the safety of every user by complying with the standards.

Safety Locks and Related Requirements
The safety lock is a key component for the safety of the suspended platform, and its function is to ensure the stability and safety of the suspension platform. Therefore, the suspended platform must be equipped with a safety lock, which should be firmly connected to the suspension platform to ensure that it can play a role quickly and effectively in emergency situations. The pendulum - type safety lock has an automatic rope - locking function. When the longitudinal inclination angle of the platform during operation exceeds 8°, the safety lock will start immediately, automatically lock the rope and stop the operation of the suspended platform, thus ensuring safety. The effectiveness of the safety lock is crucial, and it must be used within the valid calibration period. The valid calibration period usually does not exceed one year to ensure that it is always in good working condition.

Travel Limit Baffle and Switch
Requirements: To ensure safety, the suspended platform must be equipped with a travel limit device, which must have a sensitive, reliable and effective triggering function. Once triggered, the device should immediately stop the operation of the suspension platform, thereby effectively preventing the occurrence of roof collision accidents. The action mode of the travel limit device needs to be directly triggered by the suspension platform itself.

Steel Wire Rope Specifications and Installation
Requirements: Each lifting point of the suspended platform must be equipped with two steel wire ropes, one of which should be used as a safety rope. When the suspended platform is working normally, the safety steel wire rope can pass through the safety lock smoothly. The rope end of the steel wire rope must be fixed firmly and reliably. When using a rope clip for fixing, it should first go around the thimble and then be fixed. At the same time, it is necessary to ensure that the rope clip splint is located on the stressed side of the steel wire rope, and the U - bolt should be placed at the tail end of the steel wire rope to avoid positive and negative interleaving. In addition, the rope clip should be tightened appropriately so that the diameter of the two steel wire ropes is flattened by one - third. Finally, an arc - shaped observation port is reserved at the end for easy observation and adjustment.

Requirements for the Use of Safety Life Ropes
Operators on the suspended platform must be equipped with a safety life rope independent of the suspension platform, and it must be ensured that the rope has no safety hazards such as damage and corrosion. The fixed end of the safety life rope must be firm and reliable to ensure its safety during use. When the safety life rope is set on a wall column or other structures with edges and corners, appropriate protective measures should be taken, such as wrapping with rubber or wear - resistant materials, to prevent the edges and corners from damaging the rope.

Hoist and Manual Release Device
The connection between the hoist and the suspension platform must be firm and reliable. The hoist should have an excellent rope - threading function to avoid rope jamming. To ensure safety, the hoist must be equipped with a brake, and the brake should be sensitive and reliable. In addition, the brake must be equipped with a manual release device to ensure that its action is also sensitive and reliable. The function of the manual release device is that once the electrical system of the suspended platform is short - circuited and the hoist cannot operate normally, the operator can use it to gradually lower the suspension platform to the ground.

Emergency Stop Switch Function
The suspension platform must be equipped with an emergency stop switch button that can quickly cut off the main power control circuit in an emergency. The circuit design of this switch should be independent of other control circuits to ensure that the power can be cut off quickly in an emergency. In addition, the color of the emergency stop switch should be eye - catching red, and it must be manually reset to ensure that the power can be restored in time after the emergency is lifted.

Requirements for Suspension Mechanism
Ensure that the steel structure part of the suspension mechanism has no plastic deformation, cracks or severe corrosion, and the weld surface should be intact without cracks or pores. Each structural connector of the suspension mechanism must meet the specified requirements in the "Instruction Manual". If bolts are used for connection, effective anti - loosening measures must be taken, and the exposed part of the bolt thread must be controlled between 0 and 3 threads. The ratio between the anti - overturning moment and the overturning moment of the suspension mechanism should strictly follow the relevant requirements in the "Instruction Manual", and the ratio must not be less than 3.

Illustration of On - site Safety Hidden Dangers
On the construction site, various safety hidden dangers are often encountered. To ensure construction safety, we must always be vigilant and take effective measures to prevent them. The following are some illustrations of common on - site safety hidden dangers, hoping to attract everyone's attention. The lack of a travel limit baffle and the failure to connect the travel limit control line are safety hidden dangers that must attract great attention on the construction site. The safety rope is severely worn and is illegally tied to the support. This series of safety hidden dangers also need to attract our great attention on the construction site. The safety rope lacks edge and corner protection, and the counterweight block is severely damaged. These safety hidden dangers must be highly valued by us on the construction site. When installing the steel wire rope clips, their directions are staggered, resulting in the threads of the connector bolts not being fully exposed. This safety hazard also needs to attract attention on the construction site. The position of the front support point is unstable, the inclination angle is too large during erection, or the front support point is directly suspended in the air. These may cause uneven stress on the wooden board, thus leading to safety hidden dangers. The front support is not stably placed on the edge of the structure, which is a safety hazard.
