San Severo SimThe 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.
Remind customers that there are still many areas to pay attention to when maintaining and maintaining the lifting platform. We also hope that customers and friends can pay more attention when using it to ensure the safety of personnel and property, regularly maintain and extend its service life, so we must make it clear based on the actual operating height and actual load capacity when using electric elevators. If the frequency is too high the matching degree of electric elevators is how the height of the electric elevator can be combined with the operating height. Electric elevators are not used frequently, which effectively solves the problem of load capacity. If the frequency of use is too high and the height is relatively high, we recommend using a guide rail electric elevator. This type of electric elevator is not easy to malfunction under high-frequency operation, By solving the load capacity and frequency of use, the matching problem of electric elevators is effectively solved. Concept of electric elevator rotary valve: The electric elevator rotary valve is a type of valve that quickly opens and closes, and the rotary valve can reduce oil pipeline channels and optimize line settings.
San Severo .Construction electric elevators should be equipped with travel limit switches, as follows: automatic reset type upper and lower limit switches should be installed on construction electric elevators, but the upper and lower limit switches should not be triggered as high
From the above comparison, it can be seen that hydraulic electric lifting mechanisms have stable lifting, low noise, long service life, large load bearing capacity, and are relatively simple, making them suitable for use in stage equipment.
.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.
Stage equipment safety door. To prevent personnel from extending their heads, hands, and feet out of the shaft and objects from falling into the vertical shaft. Its vertical position should be closed,San Severo Scissor fork electric lifting table, 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, and car roof doors not being closed.; Door interlocks should be installed on both the vertical and passenger compartment doors.
Spiral electric lifting mechanism: With all the functions of a regular lifting platform, the main feature is that the equipment occupies a small foundation pit and has a large stroke. The equipment has a height of only 200-500mm and a travel distance of up to 14m. It is particularly suitable for buildings with stages built on two or more floors due to space constraints.
When the distance between the outer edge of the construction electric elevator and the edge line of the external overhead power line cannot meet the requirements in the table above, effective protective measures should be taken.
Setting requirements: Construction electric elevators should be equipped with up travel (limit) switches.
Work is essential,San Severo Aluminum alloy electric elevator, and the main protective accessories include safety belts, guardrails, protective covers platforms and stairs, etc.
Meticulous workmanship.Flat screw mechanical electric lifting mechanism: The lifting platform of this structure has the advantages of small civil engineering coordination, shallow foundation pit required, large stroke, stable operation, low noise, accurate positioning,San Severo Three phase electric elevator, and low cost. Adopting a horizontal screw drive and a scissor fork structure to achieve the lifting motion of the table it can be stopped arbitrarily within the range of travel.
The connection method and angle between the wall bracket and the building structure should comply with the requirements of the user manual.
The use of standard section connecting bolts should comply with the user manual and specification requirements.
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.
reform.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.
Safety devices: Electric elevators for construction should be equipped with overload detection devices. When the load inside the cage exceeds 10% of the rated load capacity, the overload detection device will give a warning signal inside the cage,
When the landing door is closed, the full width of the lifting passage opening should be covered.
San Severo .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
Chain type electric lifting mechanism: With a good guiding mechanism, it can ensure that the equipment does not tilt during operation. Gear and rack electric lifting mechanism: precise transmission and high cost.
Setting requirements: Drainage measures should be set up for the foundation of construction electric elevators to ensure smooth drainage.
