XigenSmall ele
XigenFully eleWhen 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.
Every theater is a public place with a large number of people, and safety considerations should be taken into account in stage design. According to relevant national regulations, in order to prevent accidents caused by the crushing of electric elevators or improper control by drivers. Electric elevators should be equipped with the following necessary safety devices to ensure that the car of the electric elevator stops rising or falling in a timely manner.
Xigen.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 quality of the standard section should comply with the product manual and specification requirements.
.When the door is closed, except for the gap between the lower part of the door that should not exceed 35mm any through-hole and opening size related to the distance between any door and adjacent moving parts, 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.
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, rather than in the shaft; A buffer should be installed that can absorb the energy of the moving mechanism and reduce impact.
The safety bulletin board for construction electric elevators should be hung at the protective shed of the electric elevator,XigenSmall and simple electric elevator, with a size of 8 meters by 2 meters.
The foundation production and acceptance of electric elevators for foundation construction should comply with the user manual and regulatory requirements.
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.
Every theater is a public place with a large number of people, in order to prevent accidents caused by the crushing of electric elevators or improper control by drivers. Electric elevators should be equipped with the following necessary safety devices to ensure that the car of the electric elevator stops rising or falling in a timely manner.
Test method.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
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.
It is reported that a fixed electric elevator has good lifting stability and can only be used for fixed operations, making high-altitude operations easier
Setting 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.
Quality improvement.Stage equipment safety door. To prevent personnel from extending their heads,Xigen15 meter electric elevator, hands,Xigen6m electric elevator, 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, and car roof doors not being closed.; Door interlocks should be installed on both the vertical and passenger compartment doors.
Installation position of upper limit switch: Under normal working conditions, the distance between the upper limit switch and the upper limit switch is 0.15m for SC type construction electric elevators, and 0.15m for SS type construction electric elevators (person)
Mechanical devices controlled by cage movement should not be used to open or close the landing door.
Xigen.The landing door should meet the requirements of the specifications and achieve standardization.
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, efforts will inevitably be made to design and produce high-altitude lifting platform vehicles.
Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.
