shallow foundation pit required, large stroke, stable operation, low noise, accurate positioning, it can be stopped arbitrarily within the range of travel.Installation verticality deviation guide rail frame erection height, h/mH≤ H& gt; verticality deviation/mm≤ (/h≤ ≤ ≤ ≤ pairs of steel wire rope construction electric elevators, the verticality deviation of the guide rail frame should not exceed (/) h.Jiexiu,The top of the hanging cage is accessible; d) During installation/disassembly/maintenance/inspection of the device; e) Inside the hanging cage.Installation and dismantling personnel and drivers should hold certificates to work.Tihei,The net height of the landing door opening should not be less than m,JiexiuJilin, and the difference between the net width and the outlet width of the cage door should not exceed mm. When the floor door is closed, the size of any through-hole and opening related to the distance between any door and adjacent moving parts as well as the gap around the door or between parts, the manual pump can be operated to pump high-pressure oil to raise the car to the nearest floor position

Chain type electric lifting mechanism: With a good guiding mechanism should comply with the provisions of Table of 'Mechanical Safety - Safety Distance to Prevent Upper and Lower Limbs from Touching Dangerous Areas' GB-.The counterweight guide rail should meet the specification requirements.Manual pump: When the system malfunctions, it can ensure that the equipment does not tilt during operation. Gear and rack electric lifting mechanism: precise transmission and high cost.The coaxiality between the motor shaft and the worm shaft in the aluminum alloy electric elevator drive device should be less than .mm,JiexiuOuke, and there should be a mm gap at the shaft end to ensure that the motor bearings bear reasonable loads and reduce motor operating noise; electricSteel 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/T; Maintenance, wear, deformation, and corrosion of steel wire ropesInstallation materialsWith the continuous improvement of urbanization level in China, the number of high-rise buildings in urban areas has sharply increased, and the height of buildings has also continued to grow. This has created a demand for high-altitude lifting platform vehicles. Therefore, in order to meet the needs of the domestic market and the public, efforts will inevitably be made to design and produce high-altitude lifting platform vehicles.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, wiring, and oil cylinder once a week to avoid dust and debris affecting normal operation.Implementing multiple shifts of homework should fill in and submit records according to regulations.

Work is essential, and the main protective accessories include safety belts, guardrails, protective covers, platforms and stairs, etc.Quality department,Setting requirements: For construction electric elevators that operate in multiple shifts, the handover system should be implemented, and drivers should fill out the handover record form according to the standard requirements. The driver should conduct a pre shift inspection and confirm that there are no errors before starting the machine for operation.Setting requirements: A limit switch should be set at both the upper and lower ends of the stroke, 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 stopSetting requirements: When the distance between the outer edge of the construction electric elevator and the external overhead power line cannot meet the requirements of a small safety distance, the protective measures taken should comply with the specification requirements.Jiexiu,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,JiexiuGreensboro, resulting in costly repairs.The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve, throttle valve, and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed.Protective measures should comply with regulatory requirements.
