PwotskElectric
PwotskElectricDuring 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.
Mechanical devices controlled by cage movement should not be used to open or close the landing door.
Pwotsk.It is strictly prohibited to use travel limit switches as switches to stop operation.
The spacing between wall brackets and the height of guide rails above the high attachment point should comply with the requirements of the user manual.
.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, but safety should be maintained.
Double layer steel mesh: The diameter of the steel bars is 12mm, with a spacing of 200mm.
Operating cost advantage and low failure rate: Due to the use of advanced hydraulic systems and good methods,PwotskElectric high-altitude elevator, the operating failure rate can be reduced to a low level.
Setting requirements: Each landing entrance should be equipped with a landing door, which should cover the opening with its full width, and should not open towards the lifting passage.
When a suspension cage with a rated load capacity acts on the buffer at a speed greater than the rated speed of 0.2m/s, the average deceleration of the suspension cage should not exceed 1g,PwotskWalking electric elevator, and the time when the peak deceleration exceeds 5g should not exceed
Secondly, for the replacement of hydraulic oil on the lifting platform, it is recommended to replace it every three months. If the frequency of use is not high, it can be replaced once a year. The hydraulic oil must be clean, and after changing the hydraulic oil, it must be automatically lifted and lowered 2 to 3 times to ensure that the air in the oil cylinder is completely discharged maintain sufficient space, it can automatically cut off the oil circuit and stop descent
Monthly maintenance and inspection of hydraulic lifting platform rollers, intermediate shafts and bearings, oil cylinder pin shafts and bearings, boom hinge shafts and bearings for wear. Add some oil to each part to extend the service life of the lifting platform bearings. The quality and level of hydraulic oil. The lifting platform should be raised throughout the entire process, and at this position, the hydraulic ground should be 40-50 millimeters higher than the bottom of the box. If the hydraulic oil becomes dark, sticky, or has foreign objects such as gravel, it should be replaced in a timely manner (32 # hydraulic oil). Annual maintenance and inspection of all hydraulic pipelines and joints of the lifting platform. The pipeline must not be damaged and the joints must not be loose. All joints must be tightened. Remove and disassemble the lowering valve of the lifting platform, blow out the plunger with compressed air, then install it and reinstall it. Drain and discard the hydraulic oil,PwotskElectric elevator 6 meters, tighten the joint, remove the oil filter, clean it with compressed air, the operating failure rate can be reduced to a low level.
Setting requirements: The guide rail should be rigid and flexible components such as wire ropes or chains should not be used.
Customer first.The safety bulletin board for construction electric elevators should be hung at the protective shed of the electric elevator, regularly maintain and extend its service life, and create greater benefits for the enterprise. What is the matching degree of electric elevators? Everyone has always been confused. In short, 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, 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, We suggest considering purchasing a guide rail electric elevator or a scissor fork electric elevator. The scissor fork electric elevator can achieve a maximum load capacity of 100 tons, 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.
Pwotsk.Low level doors should be equipped with interlocking devices that can verify their closed and locked positions. The action of this interlocking device should be at the entrance of the cage. Simple use should not interfere with the operation of the interlocking device. The attached wall bracket should use matching standard products. When the wall bracket cannot meet the requirements of the construction site it should be designed separately. The design of the wall bracket should meet the requirements of component stiffness, strength, stability, etc., and the production should meet the design requirements.
The wall bracket of the construction electric elevator should be intact and reliably fixed, and its attachment distance, wall bracket spacing, and end height must comply with the requirements of the 'User Manual'. The angle between the plane of the wall bracket and the normal direction of the attachment surface should not exceed 8 degrees;. When the attachment device does not meet the requirements of the 'User Manual' due to conditions, its calculation sheet, design, and production materials should be confirmed by the manufacturer or reviewed by the technical leader of the installation unit, 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, and car roof doors not being closed.; Door interlocks should be installed on both the vertical and passenger compartment doors.
