GuizhouAutomatThe 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.
Guizhou.After the limit switch is activated,GuizhouElectric hydraulic folding elevator, only professional personnel can restore the movement of the suspension cage.
Installation verticality deviation guide rail frame erection height, h/mH≤ 7070100150H& gt; 200 verticality deviation/mm≤ (1/100h≤ 70≤ 90≤ 110≤ 130 pairs of steel wire rope construction electric elevators, the verticality deviation of the guide rail frame should not exceed (5/1000) h.
.To ensure safe and reliable braking of the lifting platform and prevent accidents,GuizhouIndoor electric elevator, a hydraulic control one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure. Electrical system explosion-proof button SB1&flash; The rotation of the SB6 motor and the commutation of the explosion-proof electromagnetic directional valve are used to maintain load increase or decrease, and; Program adjustment time delay to avoid frequent movement of electric elevators that may affect their service life.
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, the door should be able to withstand and have no deformation; - Deformation not exceeding 30mm; After the test, it worked normally.
Drivers of construction electric elevators should hold special construction operations and are not allowed to operate without a certificate.
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),GuizhouElectric mini elevator, and the validity period should not exceed 1 year. Anti fall safety devices have been manufactured for five years
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.
Inspection requirements.Setting requirements: The guide rail should be rigid and flexible components such as wire ropes or chains should not be used.
Horizontal lead screw mechanical electricity
The bearing capacity of the building structure at the attachment point of the wall bracket should meet the requirements specified in the user manual for construction electric elevators.
From the perspective of the safety performance of the machinery itself those that have undergone national safety certification will not have significant safety issues. The main problem is that after using the electric elevator for a period of time, and the main protective accessories include safety belts, guardrails, protective covers, platforms and stairs, etc.
Greater than 0.04s; When the hydraulic buffer is used, the oil level shall be checked, and the action of the hydraulic buffer shall be monitored by the Electrical safety switch. When the hydraulic buffer is compressed, the cage shall not
Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.
Guizhou.The safety notice board for construction electric elevators should be prominently placed on the hanging cage for the rated load capacity and rated number of passengers of the construction electric elevator. It is strictly prohibited to use construction electric elevators beyond the rated load capacity or rated number of passengers.
The counterweight guide rail should meet the specification requirements.
The full height landing door should meet the following requirements: the net height of the landing door opening should not be less than 0m. In special circumstances when the net height of the building entrance is less than 0m, it is allowed to lower the height of the lower door opening, but in any case, the net height of the lower door opening is not less than 8m.
