What are Boom Lifts?

Elevators and lifting operation platforms are a kind of multifunctional lifting machinery and equipment, which can be divided into fixed and mobile, rail type, curved arm type, scissor type, chain type, loading and unloading platforms, etc.

Guide rail type hydraulic lifting freight elevator

Application range of elevator:

1) Special requirements for wide or long objects.

2) Generally, the height of the lift should not be higher than 25 meters.

3) The equipment is considered economical.

4) There are restrictions on the installation position or plug-in.

5) For cargo only.

6) Generally applicable to mechanical equipment transportation, textile, industrial transportation.

Lift principle

common problem

The lifts have been inspected and debugged before leaving the factory. All technical indicators meet the design requirements. When used, only the power supply needs to be connected, and the hydraulic and electrical systems do not need to be adjusted. Pay attention to the elevator in use, it must be placed on a solid and flat ground to prevent tipping during work. Press the "up" or "down" button to lift the table. If the workbench does not move, stop it immediately for inspection. When it is found that the working pressure of the electric lift is too high or the sound is abnormal, it should be shut down and inspected immediately to avoid serious damage to the machine; monthly check the working status of the shaft pin.

Container lifts are specially used for lifting containers or vehicles with containers. Its dimensions are the same as those of containers, trailers and forklifts.

A container lift is equipped on a ro-ro ship for lifting containers or vehicles with containers. Container lifts are important loading and unloading equipment on ro-ro ships.

With the development of social science and technology, elevators have spread to all corners of social life, and they have become more and more widely used, whether it is architecture, civil engineering, or people's daily life.

The following points must be noticed when installing the lift:

1.Anti-fall safety device

Anti-fall safety device is

1. Important preparations to support the operation of the lifting platform should choose a flat surface, such as the foundation is soft or uneven, and must be treated accordingly before work.
2. During the rotation operation of the lifting platform, the lower arm must be rotated before the lower arm is raised and slowly rotated, and whether the distance between the shearing arm and a platform and various equipment can meet the safety requirements. Where any country or industry regulations conflict, according to national or industry regulations 3. The operating platform operator should wear a seat belt. The live working area should be lifted according to the regulations on the ground. The lifting operation should be directed by the person in charge.

4. The power system of the elevator does not start. This is usually the most obvious switch is not activated, which is also a problem that many people tend to ignore.

5. The screw is too loose or too tight. This problem is not usually found, but there is a big hidden safety problem. Therefore, in the daily use of the elevator, we must pay attention to safety.

As a construction machine that uses a hanging cage to carry people and carry it up and down along the guide rail, the construction elevator is widely used in construction due to its simple structure, rapid 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.

As a very old topic, the safety of construction elevators has repeatedly awakened people's attention to it in the way of life annihilation. Although it is no longer a difficult problem from idea to system to supervision to implementation, it always breaks through the security defense line from the weakest link and the most easily overlooked place. The frequent occurrence of construction elevator accidents shows that there is still a large gap in its safe use. Especially now many construction units use a contract to take charge of it. They believe that after the construction machinery is outsourced, it can be managed without management and become a construction crane. The root cause of this accident. Order No. 549 of the State Council Special Equipment Safety Supervision Regulations clearly stipulates that the production of lifting machinery at construction sites (construction elevators are hoisting machinery) shall comply with the requirements of the Regulations for factory supervision and inspection, and the installation and use management shall be supervised by the construction administrative director The department shall implement in accordance with the relevant laws and regulations. Article 5 of the Regulations on the Safety Supervision and Management of Construction Hoisting Machinery states: Before the first rental of construction hoisting machinery, the user of the self-purchased construction hoisting machinery shall hold the building The heavy machinery special equipment manufacturing license, product qualification certificate and manufacturing supervision and inspection certificate shall be filed with the competent construction department of the local people s government at or above the county level where the business registration of the unit is located. Article 10 states: "The units engaged in the installation and disassembly of construction cranes (hereinafter referred to as installation units) shall obtain the corresponding qualifications issued by the competent construction department and the safety production licenses of construction enterprises in accordance with the law, and shall be contracted within the scope of their qualifications. Construction hoisting machinery installation and disassembly engineering. " Article 16 stipulates: "After the installation of construction cranes is completed, the user shall organize the relevant units such as rental, installation, supervision, etc. to conduct acceptance inspections, or entrust inspection and testing institutions with corresponding qualifications to conduct acceptance inspections. It can be put into use, and those who haven't experienced acceptance or failed the acceptance can't use it. If the general construction contract is implemented, the construction general contracting unit will organize the acceptance " ^[1] .
