UlmFolding eleSetting requirements: The quality of the standard section should meet the requirements of the product manual. Before installing the construction electric elevator,UlmFolding electric elevator, all components should be inspected, and standard sections and other components with severe wear and deformation should be replaced.
The landing door should be in a normally closed state. Without the permission of the construction electric elevator driver, the landing door shall not be opened.
Ulm.The magnetic directional valve returns to the fuel tank. To ensure stable landing of heavy objects and safe and reliable braking, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the landing speed does not change due to heavy objects. It is adjusted by the saving valve
Once again, weekly inspections should be conducted to check whether the connecting screws at various parts of the lifting platform are tightened, whether the sealing rings are damaged or ineffective, whether there is a lack of hydraulic oil, and whether the oil cylinder is leaking. It is necessary to clean the lifting frame, scissors, wiring, and oil cylinder once a week to avoid dust and debris affecting normal operation.
.Acceptance: Concrete strength grade C30, strength testing report.
The bearing capacity of the building structure at the attachment point of the wall bracket should meet the requirements specified in the user manual for construction electric elevators.
Setting requirements: The verticality deviation of the installation of the guide rail frame of the construction electric elevator should comply with the requirements of the user manual and specifications, as specified in the above table.
Safety performance: Electric elevators not only have the safety device of traditional traction elevators, but also have an overflow valve to prevent excessive system pressure during upward movement
In addition to fixed modes there are also types of car mounted mobile devices. As the name suggests, this type of lifting device is a combination of lifting equipment and car mounted systems. It is very flexible to move, and of course, it is better to use it. For example, there are such lifting devices in airports, and car stations or sports stadiums may also be equipped with such devices, as they can be moved So the scope of the operation is not limited to a specific place, but can be used wherever lifting operations are required. For example, when installing outdoor advertisements,UlmElectric light lift, mobile lifting equipment can be used to transport billboards or staff to the designated height for work. This type of equipment can also be divided into two types based on the driving mode: hydraulic lifting and electric lifting. The so-called hydraulic lifting is the use of hydraulic oil to drive and reach a specified height. The electric mode is driven by a motor or teeth to lift to a certain height. However, currently, hydraulic lifting platforms are more widely used.
Setting requirements: The verticality deviation of the installation of the guide rail frame of the construction electric elevator should comply with the requirements of the user manual and specifications, as specified in the above table.
Packaging strategy.When the distance between the outer edge of the construction electric elevator and the edge line of the external overhead power line cannot meet the requirements in the table above, effective protective measures should be taken.
When the wall bracket cannot meet the requirements of the construction site, the user unit shall organize the leasing unit, installation unit, and supervision unit to conduct acceptance. For the implementation of construction general contracting,UlmSubminiature electric elevator, the acceptance shall be organized by the construction general contracting unit. The acceptance form should be signed by the relevant responsible person.
Braking. The brake limit switch for partial motion control of the electric hoist traction machine. Assembly that restricts the operation of the lift car when it is opened to a high or low position; If the limit switch controls the overtravel switch. When the car travels to a high or low position, it will take on the function of raising or lowering. In order to prevent the lift car from crashing or sinking, stage equipment should be dismantled with over travel switches that can cut off power and cannot be automatically reset, and installed in the machine room, rather than in the shaft; A buffer should be installed that can absorb the energy of the moving mechanism and reduce impact.
Installation materials.From the perspective of the safety performance of the machinery itself, those that have undergone national safety certification will not have significant safety issues. The main problem is that after using the electric elevator for a period of time mechanical components may fall off or be damaged due to various factors. This problem depends on regular inspection and maintenance of the machinery
The counterweight steel wire rope should be equipped with an anti loosening device that is sensitive and reliable.
The net height of the landing door opening should not be less than 8m, and the difference between the net width and the outlet width of the cage door should not exceed 120mm. When the floor door is closed, the size of any through-hole and opening related to the distance between any door and adjacent moving parts, as well as the gap around the door or between parts, should comply with the provisions of Table 4 of 'Mechanical Safety - Safety Distance to Prevent Upper and Lower Limbs from Touching Dangerous Areas' GB23821-2009.
Ulm.Then, the lifting platform platform platform that carries the load needs to be balanced, and no deviation of one side is allowed. The lifting of goods does not allow people to stand on both sides of the platform, and the lifting of goods should try to maintain a stable and uniform speed.
Chain type electric lifting mechanism: With a good guiding mechanism, it can ensure that the equipment does not tilt during operation. Gear and rack electric lifting mechanism: precise transmission and high cost.
Secondly, the lifting platform is driven by electrical energy and lifted by the hydraulic system. During operation, it is necessary to avoid irregular operations. To ensure the normal and orderly operation of the lifting platform and achieve the ideal unloading level, timely inspection of various functions is essential.
