Bakersfield2 mWhen the door is closed, except for the gap between the lower part of the door that should not exceed 35mm, 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.
Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.
Bakersfield.Correct use can also greatly improve work efficiency. So how should it be used?
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.
.Before operating the construction electric elevator, routine inspections should be carried out according to regulations and inspection records should be filled out.
To ensure safe and reliable braking of the lifting platform and prevent accidents, 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.
Operating cost advantage and low failure rate: Due to the use of advanced hydraulic systems and good methods, the operating failure rate can be reduced to a low level.
Once again, weekly inspections should be conducted to check whether the connecting screws at various parts of the lifting platform are tightened, whether the sealing rings are damaged or ineffective, whether there is a lack of hydraulic oil and whether the oil cylinder is leaking. It is necessary to clean the lifting frame, scissors,BakersfieldUsed electric elevator, wiring, and oil cylinder once a week to avoid dust and debris affecting normal operation.
Check whether the sealing of components such as the oil cylinder, oil pipe, and motor of the aluminum alloy electric elevator is good and whether there is any air leakage.
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,BakersfieldPure electric curved arm elevator, hands, and feet out of the shaft and objects from falling into the vertical shaft. Its vertical position should be closed, its cabin should be full of doors, and the height of the hoistway (hall door) should not be less than 8 meters; The electric door opening and closing switches should be removed from the vertical and passenger compartment doors. In order to prevent accidents caused by vertical, passenger car doors,Bakersfield22ov electric elevator, and car roof doors not being closed.; Door interlocks should be installed on both the vertical and passenger compartment doors.
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
The foundation base or embedded parts should be fully embedded in the concrete foundation plate.
Human improper operation is the main factor causing malfunctions in scissor type electric elevators. When stacking goods, electric elevators should stack the goods neatly, during the operation of the electric elevator, it may cause the electric elevator to lose balance. After the goods are stacked completely, ropes should be used to lock the goods, so that they are not afraid of the goods during the lifting process; Careless; Scattered down
How many?.Construction electric elevators outside the lightning protection range
The coaxiality between the motor shaft and the worm shaft in the aluminum alloy electric elevator drive device should be less than 0.1mm, and there should be a 2mm gap at the shaft end to ensure that the motor bearings bear reasonable loads and reduce motor operating noise; electric
Acceptance: Concrete strength grade C30, strength testing report.
Bakersfield.Setting requirements: The quality of the standard section should meet the requirements of the product manual. Before installing the construction electric elevator, all components should be inspected, and standard sections and other components with severe wear and deformation should be replaced.
