MishkoltzElectWhen the horizontal distance between the edge of the cage and the edge of the landing or between the cage and the landing door is greater than 150mm and there is no effective protection from other structures, the side protection device for the landing entrance should be equipped.
Many theaters use a lifting platform as a vertical transportation tool for goods. The rear of the main stage or the end of the side stage in many theaters are equipped with a set container transportation lifting platform, which is used to vertically transport items from the ground to a designated location or even the stage plane. The lifting platform of the music pool is often used for transporting movable seats, etc.
Mishkoltz.The up travel (limit) switch should be of the automatic reset type.
The entrance of each landing platform must be equipped with a landing door, which must open towards the landing platform side, and the door bolt must be set on the side next to the construction electric elevator.
.Installation and dismantling personnel and drivers should hold certificates to work.
Principle of electric elevator rotary valve: When the electric elevator rises, it is necessary to first turn the handle to turn the plug to a 90 degree position until it is closed, and then turn the transmission handwheel to lower the plug and achieve sealing.
Setting requirements: The spacing of wall brackets along the vertical direction should comply with the provisions of the user manual.
The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve, throttle valve hydraulic control one-way valve, and balance valve, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge. The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects).
It is strictly prohibited to use travel limit switches as switches to stop operation.
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, it may cause the electric elevator to lose balance. After the goods are stacked completely,MishkoltzElectric mobile elevator, ropes should be used to lock the goods, so that they are not afraid of the goods during the lifting process; Careless; Scattered down
property right.The safety bulletin board for construction electric elevators should be hung at the protective shed of the electric elevator, with a size of 8 meters by 2 meters.
Secondly, 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,MishkoltzSmall electric mobile elevator, 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,MishkoltzSelf propelled electric elevator, and ensure that the lifting platform can be lifted to the rated lifting height.
Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.
Safety grounding device. In order to protect against electrical equipment. The metal casing of electrical equipment and the metal structure of electric elevators should be equipped with a safety grounding device. The grounding wire should operate multiple wires, and the neutral wire should not be arbitrarily held as a safety grounding wire. Its grounding resistance should not exceed 4 ohms; The power supply of the electric elevator can be cut off.
production.Pipeline rupture valve: When the hydraulic system pipeline ruptures and the car stalls and descends, it can automatically cut off the oil circuit and stop descent
And the decoration team is also using aluminum alloy electric elevators. What safety considerations should we consider during the use process? Many manufacturers have not clearly indicated it. Today, the mechanical editor will talk to you about aluminum alloys
Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.
Mishkoltz.Setting requirements: Drainage measures should be set up for the foundation of construction electric elevators to ensure smooth drainage.
Setting requirements: The installation and dismantling workers electricians, and other operators of construction electric elevators should have special construction operations.
The safety bulletin board for construction electric elevators should be hung at the protective shed of the electric elevator, with a size of 8 meters by 2 meters.
