which must open towards the landing platform side

The entrance of each landing platform must be equipped with a landing door, and the door bolt must be set on the side next to the construction electric elevator.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).valence,Lower limit switch: In normal working state, before the suspension cage touches the buffer, the lower limit switch first acts.Spiral electric lifting mechanism: With all the functions of a regular lifting platform, the main feature is that the equipment occupies a small foundation pit and has a large stroke. The equipment has a height of only -mm and a travel distance of up to m. It is particularly suitable for buildings with stages built on two or more floors due to space constraints.Imatra,Principle of electric elevator rotary valve: When the electric elevator rises, the rotary valve will automatically open. To close the plug valve, it is necessary to first turn the handle to turn the plug to a degree position until it is closed, and then turn the transmission handwheel to lower the plug and achieve sealing.Small safe operation distance: Circuit voltage (kV) of external power lines<~~~ Small safe operation distance (m) 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.Human improper operation is the main factor causing malfunctions in scissor type electric elevators. When stacking goods, electric elevators should stack the goods neatly, during the operation of the 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

Installation and dismantling personnel and drivers should hold certificates to work.Do not move after lifting and do not lift until the four legs are firmly supported.According to the needs of different performance genres, the form of the stage can be changed. For example, using an orchestra pit lift can combine a framed stage with a large lip or even an extended stage. In an experimental theater, using a lift can make the theater have various forms such as an end stage, an extended stage, an island stage, an intermediate stage, a T-shaped stage, or a hall.quality,Work is essential, and the main protective accessories include safety belts, guardrails,valenceMobile small electric elevator, platforms and stairs, etc.Setting requirements: For construction electric elevators with foundations installed on roof slabs, floors,valenceElectric elevator 6 meters, or other lower suspended structures,valenceSmall electric elevator platform, 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.

When 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.High quality and low price,Acceptance: Concrete strength grade C, strength testing report.Alarm devices can be divided into fixed and mobile platforms, rail type and scissor type (curved arm type) to distinguish between overload or equipment malfunction. Fixed types include: scissor lift cargo elevator chain electric elevator, and installationThe distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements, otherwise protective measures shall be taken.valence,Installation verticality deviation guide rail frame erection height, h/mH≤ H& gt; verticality deviation/mm≤ (/h≤ ≤ ≤ ≤ pairs of steel wire rope construction electric elevators, the verticality deviation of the guide rail frame should not exceed (/) h.The foundation production and acceptance of electric elevators for foundation construction should comply with the user manual and regulatory requirements.The bearing capacity of the ground under the concrete foundation plate should be greater than .Mpa.
