Construction electric elevators outside the lightning protection range
The advantages and disadvantages of several commonly used electric lifting mechanisms are as follows: hydraulic electric lifting mechanisms: using hydraulic technology, smooth lifting and low noise.
CiH .The suspension cage movement can only be resumed after operator operation.
The connection method and angle between the wall bracket and the building structure should comply with the requirements of the user manual.
.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.
The wall bracket of the construction electric elevator should be intact and reliably fixed, and its attachment distance, 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, and verified by experts.
Buffer. In order to increase the energy for the car to hit the top or sink to the bottom. Remove rubber or sponge from the buffer and cabin to increase their impact energy; Rope groove slipping and other accidents caused the car to suddenly fall, resulting in a safety clamp. To prevent breakage of the lifting wire rope. A safety clamp that can simultaneously cut off the power supply and stop the car from falling should be removed from the car. A car without safety tongs is not allowed to ride or carry people. If it is a simple electric elevator, there should be a safety device (such as a safety stop pin) to prevent people from suddenly falling when loading and unloading goods in the car; Electric elevators with three or more floors (including three floors) for passengers or passengers.
Setting requirements: The quality of the standard section should meet the requirements of the product manual. Before installing the construction electric elevator, all components should be inspected, and standard sections and other components with severe wear and deformation should be replaced.
Stop.
The pump body adopts an integrated pump station, which can also be selected according to customer requirements to meet customer ideal requirements.
technological innovation.To ensure safe and reliable braking of the lifting platform and prevent accidents, a hydraulic control one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure. Electrical system explosion-proof button SB1&flash; The rotation of the SB6 motor and the commutation of the explosion-proof electromagnetic directional valve are used to maintain load increase or decrease, and; Program adjustment time delay to avoid frequent movement of electric elevators that may affect their service life.
Human improper operation is the main factor causing malfunctions in scissor type electric elevators. When stacking goods, electric elevators should stack the goods neatly, which is better than stacking them in the center of the cargo stacking area of the cargo elevator to avoid imbalance between the two ends of the stacking area. Eventually, during the operation of the electric elevator,CiH Portable electric elevator, it may cause the electric elevator to lose balance. After the goods are stacked completely, ropes should be used to lock the goods, so that they are not afraid of the goods during the lifting process; Careless; Scattered down
The use of a lifting platform as a tool for storing performance blankets, soft scenery, etc. In some theaters, there is a soft scenery storage lifting platform located at an appropriate location on the stage for the storage of blankets, soft scenery, etc.
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, 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.
How much does it cost?.During the use period, the user unit should organize professional technical personnel to inspect the construction electric elevator monthly according to the standard requirements, and record the inspection results.
If the set screw is loose, be sure to pin it tightly to prevent accidents caused by the shaft pin falling off. Hydraulic oil should be kept clean and replaced every 6 months.
Electric elevators used in various places.
CiH .The setting of the cable guide frame should comply with the user manual and regulatory requirements.
The end height of the guide rail frame above the high attachment point should comply with the provisions of the user manual.
Steel 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/T20118; Maintenance, wear, deformation, and corrosion of steel wire ropes
