The construction and dismantling of mobile scaffolding must undergo special training, which is the core prerequisite for ensuring operational safety and efficiency. Due to its structural characteristics (mobility, high-altitude operation properties) and potential risks (collapse, overturning, high-altitude falling, etc.), untrained personnel can easily cause safety accidents and also lead to low efficiency in construction/demolition. The following explains the necessity, core content, and relevant regulatory requirements of training:
1、 Why is special training necessary?
The particularity of mobile scaffolding brings operational risks
Unlike fixed scaffolding, mobile scaffolding comes with universal wheels, which require a balance between "stability" and "mobility" during construction (such as wheel lock fixation and verticality adjustment). If the principle of balance is not mastered, collapse may occur due to loose wheel locks or tilting of the scaffolding.
The principle of "top-down and symmetrical removal" shall be followed during removal. If the removal is carried out at will (such as removing the bottom upright or slant support first), it is easy to cause overall instability, while ordinary workers may make operational errors due to lack of process awareness.
Standardize and specify the requirement for 'certified employment'
According to the "Regulations on the Management of Special Operation Personnel in Construction", the construction and dismantling of scaffolding belong to the category of special operations. Operators must undergo training recognized by the housing and construction department and obtain a "Special Operation Certificate" (Construction Scaffolder). Otherwise, it is considered a violation of regulations and the enterprise will face administrative penalties.
2、 The core content of training (directly affecting safety and efficiency)
Basic Theory and Normative Cognition
The structural principle of mobile scaffold: such as the bearing limit of upright pole, the influence of cross bar spacing on stability, the role of slant support (to prevent lateral deformation of the frame), etc., to avoid overloading or structural defects caused by "building by experience".
Safety operation red line: such as maximum erection height (usually ≤ 12m, exceeding which requires special plans), work load limit (strictly prohibit concentrated stacking of heavy objects), taboos during movement (prohibit pushing when there are people or objects on the rack), etc.
Practical skills training
Key steps for building:
Site inspection (flatness, bearing capacity, avoiding direct installation on soft ground);
Leveling and locking of wheel seat (ensure all 4 wheel locks are locked, calibrate verticality with a level to ≤ 1/200);
Correct operation of quick connectors (such as "locking confirmation" for snap on locks - hearing a "click" sound and visually seeing the lock tongue pop out);
Synchronous installation of protective facilities (such as guardrails and toe boards need to be erected synchronously with the frame to avoid time-consuming installation in the later stage).
Special demolition techniques:
Removal sequence (first remove scaffold board → cross bar → slant support → upright bar, and it is forbidden to work up and down at the same time);
Component transfer and stacking (high-altitude throwing is prohibited, and "hand to hand" transfer or specialized lifting bags are used to avoid component scattering and increase sorting time);
Emergency handling (if the frame is found to be tilted during dismantling, it needs to be stopped immediately and temporarily reinforced).
Emergency response capability
The training should include adjustment methods for slight tilting of the frame, temporary reinforcement measures for failed connectors, self rescue in case of sudden falls (such as correct use of seat belt hooks), etc., to reduce the risk of accidents.
3、 The added value of training: improving efficiency
Professional training not only ensures safety, but also improves construction/demolition efficiency through standardized operations:
Workers master "pre assembly techniques" (such as pre assembling 2-layer frame units on the ground) to reduce high-altitude operation time;
Familiar with component compatibility (such as quick matching of horizontal bar specifications and vertical bar interfaces), to avoid rework caused by misuse of accessories;
Clarify team division of labor (such as one person leveling the wheel seat, two people installing the frame, and one person laying the scaffold board), form a flow operation rhythm, and improve efficiency by more than 40% compared to disorderly operations.
summarize
The construction and dismantling of mobile scaffolding are highly technical and high-risk operations, and special training is a legal requirement and a dual guarantee of safety and efficiency. Enterprises need to choose qualified training institutions to ensure that workers not only master standardized operating procedures, but also can flexibly respond to on-site problems, avoiding safety accidents or rework waste caused by "saving training costs".
