SilmhantanScisWhen 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, all equipped with imported high-quality pump stations, which can also be selected according to customer requirements to meet customer ideal requirements.
Silmhantan.Attention should be paid to the occurrence of oil leakage on the aluminum alloy lifting platform to avoid secondary damage caused by a shortage of hydraulic oil. Overloading work is prohibited during use
The counterweight guide rail should meet the specification requirements.
.Setting requirements: Before starting work every day and changing shifts, the driver of the construction electric elevator should inspect the construction electric elevator according to the requirements of the user manual and specifications, record the inspection results, and report any problems found to the user unit.
Protective measures should comply with regulatory requirements.
Principle of electric elevator rotary valve: When the electric elevator rises, 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 wall bracket of the construction electric elevator should be intact and reliably fixed, and its attachment distance, wall bracket spacing and end height must comply with the requirements of the 'User Manual'. The angle between the plane of the wall bracket and the normal direction of the attachment surface should not exceed 8 degrees;. When the attachment device does not meet the requirements of the 'User Manual' due to conditions, its calculation sheet, design, and production materials should be confirmed by the manufacturer or reviewed by the technical leader of the installation unit, and verified by experts.
It is strictly prohibited to use travel limit switches as switches to stop operation.
Braking. The brake limit switch for partial motion control of the electric hoist traction machine. Assembly that restricts the operation of the lift car when it is opened to a high or low position; If the limit switch controls the overtravel switch. When the car travels to a high or low position, it will take on the function of raising or lowering. In order to prevent the lift car from crashing or sinking, stage equipment should be dismantled with over travel switches that can cut off power and cannot be automatically reset, and installed in the machine room, rather than in the shaft; A buffer should be installed that can absorb the energy of the moving mechanism and reduce impact.
Customer first.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
During normal operation, the horizontal distance between the closed cage door and the closed landing door should not exceed 150mm. Otherwise, measures should be taken to make it meet the requirements, or side protection devices at the entrance of the landing station that meet the requirements should be equipped. The distance between any opening between the side protection device and the hanging cage or landing door should not exceed 150mm.
When the landing door is closed, the full width of the lifting passage opening should be covered.
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, as well as the gap around the door or the gap between parts,SilmhantanThree phase electric elevator,SilmhantanElectric tatami elevator, should comply with the provisions of Table 4 of GB 23821-2009.
plan.Horizontal lead screw mechanical electricity
The device should be used within the valid calibration period and operate effectively and reliably. The anti fall safety device should have a valid inspection certificate (or inspection report), and the validity period should not exceed 1 year. Anti fall safety devices have been manufactured for five years
The use of a lifting platform as a tool for storing performance blankets, soft scenery, etc. In some theaters there is a soft scenery storage lifting platform located at an appropriate location on the stage for the storage of blankets, etc.
Silmhantan.When the door is closed soft scenery, 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.
Civil engineering advantages: The pit depth of the guide rail type lifting platform is generally around 150-300mm, and its attachment distance, wall bracket spacing, and end height must comply with the requirements of the 'User Manual'. The angle between the plane of the wall bracket and the normal direction of the attachment surface should not exceed 8 degrees;. When the attachment device does not meet the requirements of the 'User Manual' due to conditions,SilmhantanElectric boom elevator, its calculation sheet, design, and production materials should be confirmed by the manufacturer or reviewed by the technical leader of the installation unit, and verified by experts.
