TevesoAluminumPrinciple of electric elevator rotary valve: When the electric elevator rises, the rotary valve will automatically open. To close the plug valve, it is necessary to first turn the handle to turn the plug to a 90 degree position until it is closed, and then turn the transmission handwheel to lower the plug and achieve sealing.
The safety bulletin board for construction electric elevators should be hung at the protective shed of the electric elevator with a size of 8 meters by 2 meters.
Teveso.The impact load can cause early wear, fracture, and fragmentation of mechanical structural components, as well as generate impact pressure in the hydraulic system, which in turn can damage hydraulic components, oil seals, and high-pressure oil
Manual pump: When the system malfunctions, the manual pump can be operated to pump high-pressure oil to raise the car to the nearest floor position
.A complete lifting platform accessory can be selected and customized according to different places, venues, and environmental usage conditions. Meet the needs of different users. So why lifting platforms can be used and installed in so many industries and places is because they can achieve multi-purpose, demonstrate multifunctional,TevesoSmall hydraulic electric elevator, meet various different needs, and win market demand. In modern industrial transportation processes, lifting platforms have begun to play an increasingly important role, whether in airports, docks,TevesoElevator platform electric, warehouses, floors, workshops and other places that require rapid loading and unloading of goods, they have played a very practical value, It has also brought great contributions to the entire industry and even the entire economic development. However, long-term operation and use of these devices inevitably lead to wear and consumption, and regular maintenance and upkeep are essential. Otherwise, the gains and losses will outweigh the losses.
Especially suitable for steel structured factories and at that time, suitable for both indoor and outdoor installation.
The scissor type electric elevator is a widely used high-altitude operation special equipment. Its scissor mechanical structure ensures high stability of the lifting platform, wide working platform, and high bearing capacity, making the high-altitude operation range wider and suitable for multiple people to work simultaneously. It makes high-altitude operation more efficient and safer
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.
The upward movement of the hydraulic cylinder involves lifting heavy objects, and the return oil from the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve. The additional pressure relief valve is used for adjustment, and the pressure gauge reads the value when observing the pressure gauge
Installation verticality deviation guide rail frame erection height, the verticality deviation of the guide rail frame should not exceed (5/1000) h.
Direct labor.Secondly, for the replacement of hydraulic oil on the lifting platform, it is recommended to replace it every three months. If the frequency of use is not high,Teveso4 meter high electric elevator, it can be replaced once a year. The hydraulic oil must be clean, and after changing the hydraulic oil, it must be automatically lifted and lowered 2 to 3 times to ensure that the air in the oil cylinder is completely discharged, maintain sufficient space, and ensure that the lifting platform can be lifted to the rated lifting height.
The setting of the cable guide frame should comply with the user manual and regulatory requirements.
When the horizontal distance between the edge of the cage and the edge of the landing or between the cage and the landing door is greater than 150mm and there is no effective protection from other structures, the side protection device for the landing entrance should be equipped.
The scissor type electric elevator is a widely used high-altitude operation special equipment. Its scissor mechanical structure ensures high stability of the lifting platform, wide working platform, and high bearing capacity, and the neutral wire should not be arbitrarily held as a safety grounding wire. Its grounding resistance should not exceed 4 ohms; The power supply of the electric elevator can be cut off.
Non automatic reset upper and lower limit switches should be installed at both the upper and lower ends of the stroke, which should be able to cut off the power supply before the suspension cage and other mechanical stop devices (such as buffers),
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.
Teveso.After the electric elevator passes the inspection, the user unit shall organize the leasing unit, installation unit, and supervision unit to conduct acceptance. For the implementation of construction general contracting, the acceptance shall be organized by the construction general contracting unit. The acceptance form should be signed by the relevant responsible person.
Protective measures should comply with regulatory requirements.
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, 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.
