Safety Supervision Requirements.

Legal analysis: filing registration certificate, qualification of the demolition unit, safety license, special operation certificate of the demolition personnel, technician, safety officer, special construction plan, accident emergency plan, technical disclosure and other information required for supervision.

The top of the self-elevating tower has truncated cone type, forward or backward truncated cone type, herringbone frame type and diagonal brace frame type. All the upper rotary tower crane needs to be set with a counterweight, and its function is to support the counterweight, so as to constitute the balance moment that is required in the design and the direction of the lifting force Qi Ze moment.

Legal basis: "Regulations on the Management of Special Construction Workers with Registered Construction" Gao Lao Shed Article 6 The assessment and certification of special construction workers shall be organized and implemented by the people's construction departments of provinces, autonomous regions and municipalities directly under the Central Government or the assessment and certification agencies entrusted by them.

After the tower crane installation and dismantling personnel are trained in professional basic theoretical knowledge, they must also carry out (d) months of practice operation, pass the examination of relevant departments, and obtain the special operation qualification certificate before they can work on the job.

Tower Crane Introduction:

The crane mainly includes a lifting mechanism, a running mechanism, a luffing mechanism, a slewing mechanism and a metal structure. The hoisting mechanism is the basic working mechanism of the crane, which is mostly composed of a hanging system and a winch, and there are also heavy objects that are lifted through the hydraulic system.

The transportation section talking mechanism is used to move heavy objects horizontally or adjust the working position of the crane vertically, which is generally composed of an electric motor, a reducer, a brake and a wheel. The luffing mechanism is only equipped on the boom type crane, and the amplitude decreases when the boom is raised, and the amplitude increases when it is lowered down, and it is divided into two kinds of balanced luffing and unbalanced luffing base burning.

The slewing mechanism is used to make the boom rotate, and is composed of a driving device and a slewing support device. The metal structure is the skeleton of the crane, and the main bearing parts such as bridge, boom and gantry can be box structure or truss structure, or web structure, and some can be used as supporting beams with section steel.

The lifting machinery used in bridge construction projects, according to its different structure and performance, can generally be divided into four categories: light and small lifting equipment, bridge type lifting machinery and boom type cranes, and cable cranes. The main beam of the single-girder overhead crane bridge is mostly made of I-shaped steel or a combined cross-section of steel type and steel plate. The hoisting trolley is often assembled by chain hoist, electric hoist or hoist as a hoist mechanism.

The characteristics of jib cranes are basically the same as those of overhead cranes.

It can be used in the circular field and above it, and is mostly used for open-air loading and unloading and installation, including portal cranes, floating cranes, mast cranes, wall cranes and deck cranes. The boom crane includes: hoisting mechanism, luffing mechanism, and rotating mechanism.

Relying on the coordinated action of these mechanisms, heavy objects can be lifted and carried in a certain cylindrical air fighting room. The boom crane is mostly installed on the vehicle or other forms of transportation (moving) tools, so that it constitutes a running boom type rotary crane. Such as truck cranes, tire cranes, tower cranes, portal cranes, floating cranes, railway cranes, etc.

Safety precautions for tower crane installation and dismantling operations.

At present, the accident of the tower crane in the process of assembly and dismantling has accounted for a large part of the tower crane accident, which shows that the high-rise building is becoming more and more popular at the moment, and the towering tower body should complete its construction and dismantling, and the risk contained in it is indeed not to be underestimated. How to ensure the safety of tower crane assembly and disassembly has become an urgent problem for large tower crane practitioners.

The functions of each part of the tower crane (also known as the tower crane) can be divided into: foundation, tower body, jacking, slewing, lifting, balance arm, lifting arm, lifting trolley, tower top, driver's cab, luffing and other parts. Among them, the tower crane assembly and dismantling accident mainly occurs in the assembly and dismantling of the tower body, that is, the raised part and the lifting boom (generally the stressed member of the lifting heavy object) part, so the assembly and dismantling of these two parts should be paid attention to safety.

In general, when doing a good job in tower crane assembly and disassembly, we can start from these aspects:

1. Carefully handle the declaration procedures for disassembly and assembly. Before the tower crane is disassembled, the user shall declare to the relevant competent authorities in accordance with the regulations, provide the required declaration information, and be disassembled and assembled only after being reviewed and approved by the competent authorities.

2. Choose a disassembly team with corresponding qualifications. The use of the unit to carry out the tower crane disassembly and assembly work, must choose a team with the corresponding professional qualifications to undertake, shall not entrust the unit that has not obtained the corresponding professional disassembly and assembly qualifications to carry out the tower crane disassembly and assembly work.

3. Really prepare the disassembly and assembly plan and make the safety technical disclosure. Before the disassembly and assembly of the tower crane, the disassembly and assembly unit must prepare a detailed, practical and feasible disassembly and assembly construction plan, and write the preparation basis, engineering overview, foundation construction, tower crane installation, safety measures and other contents into the plan and review and approve the signature, and report to the entrusting unit for approval before implementation. Before the tower crane disassembly and assembly operation, the disassembly and assembly unit should be serious.

All construction personnel shall make a safety technical disclosure, and shall go through the safety technical disclosure confirmation procedures.

4. Disassemble and assemble in strict accordance with the disassembly and assembly procedures. In the process of disassembly and assembly operations, it is necessary to operate in strict accordance with the disassembly and assembly procedures according to the specific requirements of different models and specifications of tower cranes to prevent accidents.

5. Do a good job in the selection of disassembly and assembly equipment. Before the tower crane is disassembled and assembled, the corresponding lifting equipment should be selected according to the construction site situation, the maximum weight of structural parts, and the installation height.

In addition, do a good job in the safety protection measures of the disassembly site, and timely handle the acceptance procedures and permits are also important ways to ensure the safety of tower crane assembly and disassembly, especially the safety of second-hand tower cranes and tower crane rental equipment.
