Setting requirements: The foundation and foundation of the construction electric elevator should meet the requirements of the user manual. Before installing the construction electric elevator, the foundation should be inspected and accepted according to the requirements of the specifications. Only after passing the inspection can the installation be carried out.
The bearing capacity of the ground under the concrete foundation plate should be greater than 0.15Mpa.
Mingshan.The counterweight steel wire rope should be equipped with an anti loosening device that is sensitive and reliable.
The setting of the cable guide frame should comply with the user manual and regulatory requirements.
.Before operating the construction electric elevator, routine inspections should be carried out according to regulations and inspection records should be filled out.
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,MingshanGuide rail electric elevator, low noise, 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.
For customers to use and operate the lifting platform for a long time, the editor briefly introduces how to maintain and repair the lifting platform: First of all normal maintenance is mainly focused on prevention, especially if any damage or malfunction is detected and corrected or repaired in a timely manner. Careful inspection and maintenance at this time can save costs and avoid larger problems, resulting in costly repairs.
Implementing multiple shifts of homework should fill in and submit records according to regulations.
It is strictly prohibited to use travel limit switches as switches to stop operation.
The scaffolding of the parking platform should be laid tightly and firmly.
Test results.Double layer steel mesh: The diameter of the steel bars is 12mm, with a spacing of 200mm.
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.
The spacing between wall brackets and the height of guide rails above the high attachment point should comply with the requirements of the user manual.
Manual pump: When the system malfunctions, the protective measures taken should comply with the specification requirements.
Setting requirements: A limit switch should be set at both the upper and lower ends of the stroke,MingshanElectric tricycle elevator,MingshanElectric folding elevator, which should be able to cut off the power supply before the suspension cage and other mechanical stop devices (such as buffers), so that the suspension cage can stop
The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter explosion-proof electromagnetic directional valve, throttle valve, hydraulic control one-way valve, and balance valve, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge. The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects).
Mingshan.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.
Acceptance: Concrete strength grade C30, strength testing report.
