MolfetaSelf prAfter the electric elevator passes the inspection, the user unit shall organize the leasing 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.
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
Molfeta.Construction electric elevators should be equipped with travel limit switches, but the upper and lower limit switches should not be triggered as high
Pipeline rupture valve: When the hydraulic system pipeline ruptures and the car stalls and descends, it can automatically cut off the oil circuit and stop descent
.The oil cylinder and sealing components are made of imported components to solve the problem of unstable oil pressure and oil leakage of components for customers.
The connection method and angle between the wall bracket and the building structure should comply with the requirements of the user manual.
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
Drivers of construction electric elevators should hold special construction operations and are not allowed to operate without a certificate.
The shutdown device (emergency stop switch) should be non automatic reset type.
The motor of the hydraulic guide rail lifting platform is set around the wellbore,MolfetaBlue cover electric elevator, occupying a relatively small area, improving the utilization rate of the wellbore area.
Workshop cost.The L distance depends on the selected wall mount model.
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,MolfetaWarehouse 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.
Advantages of electric elevator rotary valve: Simplify the installation of electric elevator pipelines; The operation is more convenient, and the valve can be opened and closed at any time; The installation of a rotary valve reduces the friction of the sealing components; Compact structure, small size, and space saving; Increased the service life of electric elevator pipelines and solved the problem of easy oil leakage.
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.
technical service.Setting requirements: The main connection methods between the wall bracket and the building include: connecting the wall bracket with the embedded parts on the wall; Fix with wall bolts; Embedded bolts; Welding with steel structures.
Safety devices: Electric elevators for construction should be equipped with overload detection devices. When the load inside the cage exceeds 10% of the rated load capacity, the overload detection device will give a warning signal inside the cage,
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, 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.
Molfeta.In addition to ground protective fences, low level doors can be used. Low level doors should meet the following requirements: the height of the door should be between 1m and 2m. And there should be at least protective railings,MolfetaSmall electric hydraulic elevator, a half height middle crossbar, except for the gap between the lower part of the door that should not exceed 35mm, any through-hole and opening size related to the distance between any door and adjacent moving parts as well as the gap around the door or the gap between parts, should comply with the provisions of Table 4 of GB 23821-2009.
Flat screw mechanical electric lifting mechanism: The lifting platform of this structure has the advantages of small civil engineering coordination, shallow foundation pit required, large stroke, stable operation, low noise, accurate positioning, and low cost. Adopting a horizontal screw drive and a scissor fork structure to achieve the lifting motion of the table, it can be stopped arbitrarily within the range of travel.
