What should I pay attention to when using the construction site lift?

1.The lift must be placed on solid, level ground to prevent tipping over while working.

2.Work according to the specified load of the elevator used, can not be overloaded, in case of emergency, up to 10% overload is allowed.

3.Try to evenly distribute the weight in the elevator **, in special circumstances, with the allowable eccentric load, the vertical eccentric load can not exceed the rated load of the elevator 1 2, and the transverse eccentric load can not exceed 1 3. The eccentric load must be 300 mm away from the table top.

4.Round or rolled materials must be bundled and placed on the countertop.

5.It is strictly forbidden to carry people without manned protection

In recent years, the emergence of construction hoists has brought great convenience to the construction site, but at the same time, it has also brought many potential safety hazards and construction accidents. In fact, whether it is a safety hazard or an accident, most of them have reasons for improper management of construction elevators. There are many construction hoist buyers who are not clear about the precautions for construction hoists.

Precautions for hoist:

The service life of the construction hoist in the normal working environment (no corrosive environment) is 5 years (except for wearing parts).

2.The springs in the components must be replaced after about 1 year of normal use.

3.In the process of use, attention must be paid to the care and maintenance of the equipment; It is strictly forbidden to connect the electric control cabinet to other electrical equipment, otherwise you will be responsible for the consequences.

4.Safety gears must be well lubricated and regularly maintained. It is strictly forbidden to apply any lubricant to the main frame track.

5.The first 15-day oil change in the reducer gearbox of the winch should be changed once every 2 months.

6.The braking device should be inspected, maintained and maintained frequently.

7.The main wire rope has burrs and broken strands and must be replaced.

8.It is strictly forbidden to store and accumulate any sundries on the top of the cage, and it is strictly forbidden to stand in the cage.

Note: If any of the above contents is found to be abnormal, it must be stopped immediately, the manufacturer must be notified, repaired, and recorded before it can be put into use.

When the construction elevator is working at height, we must pay more attention to the occurrence of falling objects at high altitude. In the above article, we have made a relevant analysis of the causes of falling objects, and have a certain grasp of this, and now the most important thing is how to do a good job in preventing high-altitude falling objects from injuring people safety measures?

With many years of operating experience, the experts who operate the construction hoist have summed up how to better do a good job in safety protection. First of all, it should be noted that for important and large hoisting, detailed hoisting construction technical measures and safety measures must be formulated, and there should be a special person responsible, unified command, and full-time safety supervision personnel. In addition, non-professional lifting workers are not allowed to engage in lifting operations.

For each load-bearing temporary platform, it is necessary to carry out a special design and calculate its bearing capacity, and it is allowed to be used only after welding by professional welders and passing the inspection. Clean or tie up the debris and small items on the hanging objects before lifting. When engaged in high-void work, you must wear a tool bag, and large tools must be tied with a safety rope.

For the operation of the relevant construction lift, it is necessary to pay attention to safety measures, which also includes strengthening the cleaning and storage management of small items on high-altitude work sites and scaffolding, and doing a good job in anti-falling measures. When passing objects up and down, they should be passed with ropes, and they should not be thrown up and down, and tool bags should be used when passing small workpieces and tools. Try to avoid cross operations, dismantling or lifting operations, set up a warning area in the operation area, and it is strictly forbidden for irrelevant personnel to enter.

Fall prevention measures should be taken when cutting objects and materials. When lifting scattered items, a special spreader should be used for lifting.

Finally, here we also want to tell you about the preparation of safety protective equipment for operating construction hoists for aerial work, including: safety helmets and safety belts. Among them, before using the helmet, it is necessary to check whether the shell, hat lining, and hat strap are complete and effective.

Adjust the helmet lining before using the helmet so that each part of the helmet lining is separated from the cap shell by a certain space. The hoop should be adjusted according to the shape of the head, so as to prevent the hat from slipping forward to block the view when working with the head down. It is strictly forbidden to combine the two layers of hard hat top lining into one layer.

The helmet should be worn tightly and straightly, and the hat strap should be tied under the chin and fastened tightly. The validity period of the helmet is calculated from the date of completion of the manufacturing of the product, and the plastic cap shall not exceed two and a half years, and the glass fiber reinforced plastic cap shall not exceed three and a half years.

In addition, for seat belts, they must be inspected by the inspection unit every six months before they can be used. It should be noted that seat belts should be worn when working in the following conditions: (1) when it is possible to work at height, safety belts must be worn when entering the workplace;

2) When working at altitude with a height of more than two meters;

3) When working on a scaffold without scaffolding or without a barrage, the height exceeds the meter;

4) When working on sloping roofs;

5) Flat-roofed house, when there is no protective fence within meters from the edge of the roof or the roof opening;

6) Any suspended platform or workbench;

7) Any guardrail, paving filial piety socks board incomplete scaffolding;

8) Approaching the roof or ladder near the opening in the ground;

9) When there are no reliable anti-fall measures for high-altitude operations.

When the high-rise construction elevator is carried out at height, we need to pay more attention to the safety issues, and the following relevant knowledge is sorted out for you, so you should pay attention to it.

According to the relevant data, about 50% of safety accidents are caused by falling from height or related to high-altitude work, so it is extremely important to do a good job in safety protection and safety management and safety monitoring of high-altitude work. Safety protection measures should be formulated and strictly implemented for high-altitude operations. In my opinion, the following points should be paid attention to when the construction hoist is carried out for high-altitude work:

1. Personnel working at height must be in good health. Persons suffering from mental illness, epilepsy, high blood pressure, heart disease, and other diseases that are not suitable for working at heights are not allowed to participate in work at height. When it is found that the staff has drunk alcohol or is not energetic, it is forbidden to climb the height.

2. High-altitude operations must be carried out only after building scaffolding or taking measures to prevent falling. The construction hoist works on the dam crest, steep slope, roof, cliff, pole tower, suspension bridge and other dangerous edges, and safety nets or protective railings should be installed on the empty side, otherwise, the staff must use safety belts.

3. When working on scaffolding without scaffolding or without railings, when the height is exceeded, safety belts or other reliable safety measures must be taken. Seat belts should be inspected before use, and static load tests should be carried out regularly (every 6 months); The test load is 225kg, the test time is 5min, check whether there is deformation, rupture and other conditions after the test, and make a test record. Unqualified seat belts should be dealt with promptly.

4. The hook or rope of the safety belt should be hung on a strong and firm member, or on the wire rope specially used for hanging the safety belt. It is forbidden to hang on moving or unstable objects. Tool bags should be used for high-altitude operations of construction elevators, and larger tools should be tied to firm components with ropes, and they are not allowed to be placed randomly to prevent accidents from falling from heights.

5. When working at height of the construction elevator, except for the relevant personnel, others are not allowed to pass or stay below the work site, and there should be a fence or other protective devices installed below the work site to prevent falling objects from hurting people. If working on a grating platform, planks should be laid to prevent tools and equipment from falling.

6. Tools and materials are not allowed to be thrown up and down, and they should be hung down or up after being tied with ropes, so as not to injure the staff below or destroy the scaffolding. When the upper and lower floors are working at the same time, a tight and firm protective partition, canopy or other isolation facilities must be erected in the middle. Staff must wear hard hats.

In strong winds of level 6 and above, as well as bad weather such as heavy rain, thunder, and fog, open-air high-altitude operations should be stopped. It is forbidden to work on unstable structures (e.g. asbestos tile roofs). In order to prevent false boarding, warning signs should be hung at the necessary points of such structures.
