LamarElectric 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
From the perspective of the safety performance of the machinery itself, mechanical components may fall off or be damaged due to various factors. This problem depends on regular inspection and maintenance of the machinery
The entrance of each landing platform must be equipped with a landing door, which must open towards the landing platform side, and the door bolt must be set on the side next to the construction electric elevator.
Lamar.Construction electric elevators should be equipped with emergency stop switches and comply with regulatory requirements.
The list of materials for making landing doors is as follows: Table 1: List of materials for making landing doors. Landing doors should be installed at the entrance of each landing station, and the landing doors should function properly.
.Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.
With the continuous improvement of urbanization level in China, the number of high-rise buildings in urban areas has sharply increased, and the height of buildings has also continued to grow. This has created a demand for high-altitude lifting platform vehicles. Therefore, in order to meet the needs of the domestic market and the public, efforts will inevitably be made to design and produce high-altitude lifting platform vehicles.
Low level doors should be equipped with interlocking devices that can verify their closed and locked positions. The action of this interlocking device should be at the entrance of the cage. Simple use should not interfere with the operation of the interlocking device. The attached wall bracket should use matching standard products. When the wall bracket cannot meet the requirements of the construction site, it should be designed separately. The design of the wall bracket should meet the requirements of component stiffness, strength, stability, etc., and the production should meet the design requirements.
The entrance of each landing platform must be equipped with a landing door, which must open towards the landing platform side, and the door bolt must be set on the side next to the construction electric elevator.
When adding hydraulic oil it is also necessary to pay attention to the structure of the oil cylinder. Some oil cylinders are relatively complex internally, and how many lifting operations need to be carried out during filling to fully fill each position of the hydraulic oil. Therefore, when filling, try to add as much as possible, and then test and run the machine empty to see if it reaches the rated position.

Click to view.Low power consumption: When the hydraulic guide rail lifting platform descends, it is driven by the pressure generated by its own weight, greatly saving energy and reducing consumption.
When the landing door is closed,LamarFloor electric elevator, the full width of the lifting passage opening should be covered.
Steel wire ropes, pulleys, and counterweight steel wire ropes shall comply with the following regulations: the characteristics of steel wire ropes shall comply with the requirements of General Purpose Steel Wire Ropes GB/T20118; Maintenance, wear, deformation, and corrosion of steel wire ropes
Buffer. In order to increase the energy for the car to hit the top or sink to the bottom. Remove rubber or sponge from the buffer and cabin to increase their impact energy; Rope groove slipping and other accidents caused the car to suddenly fall, resulting in a safety clamp. To prevent breakage of the lifting wire rope. A safety clamp that can simultaneously cut off the power supply and stop the car from falling should be removed from the car. A car without safety tongs is not allowed to ride or carry people. If it is a simple electric elevator, there should be a safety device (such as a safety stop pin) to prevent people from suddenly falling when loading and unloading goods in the car; Electric elevators with three or more floors (including three floors) for passengers or passengers.
Inspection standard.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, except for the gap between the lower part of the door that should not exceed 35mm, 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.
In addition to fixed modes, there are also types of car mounted mobile devices. As the name suggests,LamarElectric high-altitude elevator, and of course, it is better to use it. For example,LamarMicro electric elevator, 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, 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.
The distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements, otherwise protective measures shall be taken.
Lamar.When the landing door is closed, the full width of the lifting passage opening should be covered.
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
Monthly maintenance and inspection of hydraulic lifting platform rollers, intermediate shafts and bearings oil cylinder pin shafts and bearings, boom hinge shafts and bearings for wear. Add some oil to each part to extend the service life of the lifting platform bearings. The quality and level of hydraulic oil. The lifting platform should be raised throughout the entire process, and at this position, the hydraulic ground should be 40-50 millimeters higher than the bottom of the box. If the hydraulic oil becomes dark, sticky, or has foreign objects such as gravel, it should be replaced in a timely manner (32 # hydraulic oil). Annual maintenance and inspection of all hydraulic pipelines and joints of the lifting platform. The pipeline must not be damaged, blow out the plunger with compressed air, then install it and reinstall it. Drain and discard the hydraulic oil, tighten the joint, remove the oil filter, clean it with compressed air, and then return it to the oil tank and connect the pipeline.
