The setting of the cable guide frame should comply with the user manual and regulatory requirements.
Small safe operation distance: Circuit voltage (kV) of external power lines<11~1035~110220330~550 Small safe operation distance (m) 4681015 Setting requirements: A small safe distance should be maintained between the outer edge of the construction electric elevator and the edge of the external overhead power line.
Rajibri.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 stop
The net height of the landing door opening should not be less than 8m, and the difference between the net width and the outlet width of the cage door should not exceed 120mm. When the floor door is closed, except for the gap between the lower part of the door that should not exceed 35mm, 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, should comply with the provisions of Table 4 of 'Mechanical Safety - Safety Distance to Prevent Upper and Lower Limbs from Touching Dangerous Areas' GB23821-2009.
.Once again, weekly inspections should be conducted to check whether the connecting screws at various parts of the lifting platform are tightened, whether there is a lack of hydraulic oil,RajibriElectric brick elevator on construction site, and whether the oil cylinder is leaking. It is necessary to clean the lifting frame, scissors, wiring, it can ensure that the equipment does not tilt during operation. Gear and rack electric lifting mechanism: precise transmission and high cost.
The distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements otherwise protective measures shall be taken.
Setting requirements: The verticality deviation of the installation of the guide rail frame of the construction electric elevator should comply with the requirements of the user manual and specifications,RajibriFloor electric elevator, as specified in the above table.
When adding hydraulic oil, we can extend the oil cylinder to the high position for filling. When filling, the lifting platform should not exceed the high position,RajibriElectric elevator 10 meters, and then retract the oil cylinder back to the low position to check if the hydraulic oil level is lower than the low position, and maintain it between the two.
The scaffolding of the parking platform should be laid tightly and firmly.
Customer first.Setting requirements: The anti loosening and anti loosening parts between the connecting parts should comply with the provisions of the user manual and should not be replaced by other objects. For connecting bolts with pre tightening requirements, a torque wrench or special tool should be used to accurately tighten the bolts to the specified torque value according to the specified tightening sequence. When installing standard section connecting bolts, it is advisable to place the screw at the bottom and the nut at the top.
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, mechanical components may fall off or be damaged due to various factors. This problem depends on regular inspection and maintenance of the machinery
Setting requirements: Drainage measures should be set up for the foundation of construction electric elevators to ensure smooth drainage.
The connection method and angle between the wall bracket and the building structure should comply with the requirements of the user manual.
Where is it.Safety performance: Electric elevators not only have the safety device of traditional traction elevators, but also have an overflow valve to prevent excessive system pressure during upward movement
Is the water cooling and air cooling of the hydraulic station the same?
With 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.
Rajibri.When the wall bracket adopts non matching standard products, design calculations should be carried out.
The oil cylinder and sealing components are made of imported components to solve the problem of unstable oil pressure and oil leakage of components for customers.
Tank oil temperature protection: When the oil temperature in the tank exceeds the standard setting value, the oil temperature protection device sends a signal to suspend the use of the elevator. The elevator can only be started when the oil temperature drops
