PisaMicro elecWhen a rigid 5000mm2 square or circular flat surface is applied with a normal force of 600N to either side of the door, the door may not meet the above requirements, but safety should be maintained.
When the door is closed, 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, should comply with the provisions of Table 4 of GB 23821-2009.
Pisa.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,Pisa3 meter high electric elevator,
When a rigid 5000mm2 square or circular flat surface is applied with a normal force of 600N to either side of the door, the door may not meet the above requirements, but safety should be maintained.
.When the wall bracket adopts non matching standard products, design calculations should be carried out.
Before installation, the installation unit should confirm that the foundation, foundation bearing capacity, embedded parts, and foundation drainage measures of the installed construction electric elevator and auxiliary heavy equipment comply with the requirements of the special construction plan for the installation and dismantling of the construction electric elevator based on the construction electric elevator foundation acceptance form, concealed engineering acceptance form and concrete strength report.
When the door is closed,PisaScissor fork electric lifting table, 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.
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).
Installation position of upper limit switch: Under normal working conditions, and 0.15m for SS type construction electric elevators (person)
Drainage measures need to be considered around the foundation. (Drain the accumulated water on the foundation).
analysis.Civil engineering advantages: The pit depth of the guide rail type lifting platform is generally around 150-300mm, and the top layer is not affected. It can be customized according to the location and environment.
There is no need to set up a computer room above the shaft like an elevator, and the top floor height can be installed at least 2.5 meters.
The setting of the cable guide frame should comply with the user manual and regulatory requirements.
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
Online consultation.The verticality of the guide rail frame should meet the requirements of the specifications.
Steel wire rope construction electric elevators and reusable steel wire ropes should be equipped with anti loosening rope devices, which should have compliant loosening rope switches and be able to interrupt any movement of the lifting cage until it is approved by a professional
Setting requirements: The guide rail should be rigid and flexible components such as wire ropes or chains should not be used.
Pisa.Principle 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.
Drivers of construction electric elevators should hold special construction operations and are not allowed to operate without a certificate.
Use floor doors and cage door devices on construction sites where conditions permit.
