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 spacing of wall brackets along the vertical direction should comply with the provisions of the user manual.
Jinghai.The occurrence of.
Advantages of electric elevator rotary valve: Simplify the installation of electric elevator pipelines; The operation is more convenient, and the valve can be opened and closed at any time; The installation of a rotary valve reduces the friction of the sealing components; Compact structure, small size, and space saving; Increased the service life of electric elevator pipelines and solved the problem of easy oil leakage.
.Setting requirements: For construction electric elevators with foundations installed on roof slabs, floors, or other lower suspended structures, the bearing capacity of the foundation support structure should be checked. Click here to download the construction technical information for free. Basic drainage facilities should be installed.
Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.
For customers to use and operate the lifting platform for a long time, normal maintenance is mainly focused on prevention, especially if any damage or malfunction is detected and corrected or repaired in a timely manner. Careful inspection and maintenance at this time can save costs and avoid larger problems, all equipped with imported high-quality pump stations, which can also be selected according to customer requirements to meet customer ideal requirements.
Requirements for the operation platform of the construction lowering machine and the setting of the brake reset emergency stop switch: The shutdown device (emergency stop switch) should be able to stop or maintain the electric elevator (including the power driven door) in a non working state
The landing door should be in a normally closed state. Without the permission of the construction electric elevator driver the landing door shall not be opened.
retailer.The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve, throttle valve, and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking,JinghaiElectric cargo elevator, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed.
The setting of the cable guide frame should comply with the user manual and regulatory requirements.
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, 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.
Setting requirements: The wall bracket should use the manufacturer's matching standard products.
superior quality.From the above comparison, it can be seen that hydraulic electric lifting mechanisms have stable lifting low noise,JinghaiThree phase electric elevator,JinghaiElevator platform electric, long service life, large load bearing capacity, and are relatively simple, making them suitable for use in stage equipment.
The safety overtravel of limit switches and upper limit switches should comply with regulatory requirements.
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, and corrosion of steel wire ropes
Jinghai.The setting of the cable guide frame should comply with the user manual and regulatory requirements.
Construction electric elevators should be equipped with cable guide frames and comply with regulatory requirements.
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.
